PCI: What Is The Difference Between 4G LTE and 5G NR

In this blog we are going to look at the difference between 4G LTE and 5G-NR, specifically in terms of PCI. 

 

What is PCI when it comes to 4G / 5G?

 

PCI is the Physical Cell ID and is one of the most important ways a cell identifies itself in a 4G or 5G wireless network.

The physical layer (or PHY-layer) Cell ID is what determines the Cell ID Group and Cell ID Sector, and it is this that is needed for DL synchronisation. 

DL (Downlink) Synchronisation is the process in which a UE (phone) detects the radio boundary and OFDM symbol boundary. In other words, the exact timing of when a radio frame or OFDM starts. (In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies.) 

This DL synchronisation process is done by detecting and analysing the SS Block. From a UE’s (phone’s) point of view, Downlink is the ‘receiving’ transmitting direction. The SS Block (SSB) stands for Synchronisation Signal Block and refers to the synchronisation signal and Physical Broadcast Channel (PBCH) as a single block that always moves together.

 

Why is PCI Planning important? 

 

If you are planning, designing and deploying a 4G / 5G network, then PCI Planning will be one of your most important steps. 

Making sure your network is properly designed with PCI in mind will ensure your network works efficiently and increases how your resources are utilised. 

Excellent PCI planning ensures QoS for those who are subscribed to your 4G / 5G network.

QoS (Quality of Service) is the use of technologies to control traffic on your network, ensuring that the performance of critical applications meets requirements.

The key goal here is to use QoS and PCI Planning to enable your network to prioritise traffic, offering dedicated bandwidth and lower latency.

PCI is one of the technologies used to enhance performance of business applications, WANs and service provider networks. 

Poor planning in this area can result in PCI collisions and conflicts – Which in turn, negatively impact the overall performance of your network.

 

How is the PCI value created?

 

The PCI value is created from two components – PSS (Primary Synchronisation Signal) and SSS (Secondary Synchronisation Signal). 

The PSS is used to obtain the slot, ub-frame and half-frame boundary as well as providing the cell identity within the cell identity group. 

The SSS is used to obtain the radio frame boundary (10ms) as well as enabling the UE (phone) to determine the cell identity group.

After your UE (phone) has successfully decoded the PSS and SSS, it will be able to calculate the PCI. It uses the following formula:

PCI = (3 × SSS) + PSS

 

How is PCI calculated for 4G?

 

PSS has 3 values (0,1 and 2) and is created using the Zad-off Chu sequence.The PSS helps to accomplish slot and symbol synchronisation in the time domain.

SSS has 168 values (0 to 167) and is produced using concatenation (linking together in a series) of 2 m-sequences (max length sequence). The SSS helps to achieve radio frame synchronisation.

The formula to work out PCI for 4G is therefore:

PCI = (3 * 167) + 2 = 503

This means that there are PCI values varying from 0 to 503 LTE, which in turn supports 504 unique PCIs for 4G. 

 

How is PCI calculated for 5G?

 

PSS has 3 values (0,1 and 2) and created using m-sequence. 

SSS has 336 values (0 to 335) and is generated using the product of 2 m-sequences.

In 5G-NR (a new radio access technology developed by 3GPP for the 5G (fifth generation) mobile network), the basic structure of PSS is the same but the number of SSS is increased.

The formula to work out PCI for 4G is therefore:

PCI = (3 * 335) + 2 = 1007

So the PCI values will vary from 0 to 1007. This means that 5G-NR can support 1008 unique PCIs.

 

What does this difference in PCI between 4G and 5G actually mean? 

 

In the simplest terms, 5G-NR has double the number of PCI’s, compared to LTE 4G. 

5G has more Physical Cell IDs (the actual area that the cell antenna on a cell site is covering). Each 5G NR cell has a Physical Cel lD. 5G has 1008 unique possible Physical Cell ID’s, whereas 4G has only 504. 

So if we’re connected to Vodafone on Physical Cell ID No.1, but we could also see Vodafone signals being broadcast out of that cell tower on different cell antennas using Physical Cell ID No,2 and No3, then our mobile device would know to connect to No1. It would get confused if it connected to No.2 or No.3 and impact the quality of service.

The user device connects to the one physically nearest. So for example, a Vodafone tower has two cell antennas out the top broadcasting the Vodafone signal across an area, which will overlap to a small degree. A user’s device will always want to make sure it is connecting to the same one. You don’t want to connect to one antenna and back to another – It’s this that ruins the quality of service. So you will always try and connect back to the one you were talking to, which is normally geographically the one closest to you. 

The Physical Cell ID is used to identify each space. We don’t want those numbers to overlap too often, or our devices get confused and don’t know which to connect to. If a device can see a Physical Cell ID of 2, and there’s another cell antenna using an ID of 2, it wouldn’t know which one to communicate with.

It is beneficial to know that 5G-NR has more PCI’s available in the planning stages, to enable a higher quality of service (QoS) for end user devices.



Wi-Fi and Connectivity Options for Village Halls

Did you know that village halls in need of a bit of updating and renovation can apply for a share of a £3m fund, all in honour of the Queen’s Platinum Jubilee?

 

This follows the tradition of village hall investments for Queen Victoria’s Diamond Jubilee in 1897 and King George V’s Silver Jubilee in 1935. 

 

125 lucky village hall recipients will have a share of the £3m fund, which can be put towards renovations and building improvements including Wi-Fi.  

 

You might well be hosting or celebrating in your local village hall for this weekend’s Jubilee celebrations! Village halls are often the heart of communities, bringing people together. It’s vital these hubs stay well connected with strong, reliable Wi-Fi. 

Wi-Fi for Village Halls – A Quick Guide

If you’re a part of the committee that looks after your local village hall, then you’ll know that there is an ever-increasing need for these community buildings to offer broadband and Wi-Fi access to their users. 

 

Not only will this support a wide range of community activities and events, it will also enhance the facilities you can offer as a venue to those who hire your space. 

 

So what do you need to consider to improve digital connectivity for your communities and businesses by making sure your village hall is well connected? 

 

Get a Broadband Connection


Before even thinking about Wi-Fi or broadband, you need to make sure you have a telephone landline. The only exception is if you are able to get cable or fibre access to the hall. You can read more about FTTP in one of our previous blogs here. Make sure that you have a business contract rather than residential, as it will be for public use. 

 

To get a new telephone line, order one through BT.com. After that’s done, you can upgrade to broadband. Always make sure you check with the ISP that you are able to make your internet connection available to the public before placing your order. 

 

If you want to get broadband without a landline, you would need to be able to have a cable, full fibre or mobile broadband connection. More on that later! 

 

Not got an official postal address? Some village halls don’t actually have an official post office address which can cause problems with some ISP’s as they may insist that you have one in order to place an order. If you find this is the case, you can contact the Post Office and request an official address here.

 

Some ISP’s will accept what’s known as an ‘unserved’ building but they may ask to do an initial survey before they confirm your order.  

 

How much will it cost to install Wi-Fi in a village hall?

You will need to incur some costs to get Wi-Fi successfully set up in your village hall. Bear in mind the following likely outgoings:

  • Installation and connection costs for a new telephone line (plus VAT) and broadband connection (if required)
  • Line rental for the telephone line (ongoing costs)
  • Data usage charges from broadband / Wi-Fi use (ongoing costs)
  • Any work required to install the Wi-Fi router in a secure location, plus additional devices that may be needed to boost Wi-Fi signal 

 

You can help keep costs to a minimum by shopping around for the best contract available on price comparison websites. Remember you need a business contract, not a residential one! Make sure you balance out the costs with data usage limits and of course, reliability.

 

Remember though, making improvements with the Wi-Fi in your village hall is investing in its successful future. It’s vital that these community hubs are well connected for their users. And even better if you can get the costs covered by securing part of the £3m Jubilee fund!

 

Security

 

We cannot express enough how important it is to make sure that your Wi-Fi is secure. You should manage and filter the access to your Wi-Fi signal. 

 

If you were to allow unmanaged access to your Wi-Fi, people may use your broadband connection for illegal purposes. By providing the Wi-Fi for this, you could be liable. 

 

Luckily for you, it’s super easy to manage your Wi-Fi security – And definitely not something that should put you off setting up a Wi-Fi connection in your village hall. 

 

To minimise the risk of inappropriate use, you should:

 

  • Install your router in a secure place where only authorised users are able to physically access it. Don’t let people connect to your router via Ethernet cable as they could make changes.
  • Routers usually display the passwords you need in order to manage and access your Wi-Fi connection. If you think it’s possible for unauthorised users to access this information, then consider changing the User ID and admin password (instructions on how to do this should be in your router user guide).
  • Regularly change your Wi-Fi access password for users. This means that only current users will be able to use your Wi-Fi connection, rather than someone who isn’t authorised or is re-using a password they’ve previously been issued with.
  • Always ensure that the parental control setting is switched on. This prevents access to any unsuitable websites on your Wi-Fi connection. You can use your router manual to set appropriate firewall settings to set the level of restriction required. 

 

 

The router in our village hall doesn’t reach the whole building

 

If you already have a router installed in your village hall, but it’s not reaching far enough and you’re struggling with black spots or slower Wi-Fi in certain places then you may need to extend your Wi-Fi coverage. 

 

This is particularly relevant if you have a large village hall building – The signal just may not be strong enough to reach everywhere it needs to from one router. 

 

We mentioned above that it’s important for the router to be in a secure area so unauthorised people cannot access it. This could mean that it’s been placed in a less than ideal location for signal strength and connectivity. It’s vital to balance the two! 

 

Ideally, you will be able to place the router in a central location, but if that is not the case then you may need to install other devices to extend the signal to other locations within your village hall building. You could potentially use a powerline adapter or a Wi-Fi extender to boost the signal strength and get wider Wi-Fi coverage in the building. 

 

Mobile Broadband for Rural Village Halls

You and your users might not be in London, but that doesn’t mean that you don’t expect the same Wi-Fi connection that you get in urban areas – Despite being in more rural ones. 

 

Unfortunately there are many parts of the countryside that are suffering from a broadband deficit – Indeed, there seems to be a connectivity imbalance across the countryside, with many village halls struggling.

Over the past year particularly, we’ve installed countless numbers of external 4G antennas and routers in rural areas, effectively replacing the broadband through the telephone cable using a data SIM card.

 

You can read more about our 4G Mobile Broadband solutions in a previous blog of ours here

 

If you are wary about whether Mobile Broadband could work in your more rural village hall, then our Cellular Survey could be just what you need. We can map the availability of cellular and data coverage within a building and report the details of phone coverage for 2G, 3G, 4G/LTE and 5G. We can measure the cellular connectivity, data upload and download speeds and the occurrence of dropped and failed calls for all the main mobile network operators.

What is 6GHz Wi-Fi?

Did you know that following the historic decision by USA’s FCC in April 2020 to release 1200 MHz of bandwidth in 6 GHz space for unlicensed use, UK regulators cleared unlicensed wireless usage in the 6 GHz spectrum to give 6GHz WiFi a huge boost back in July 2020. 

 

This regulatory go-ahead enables your router to broadcast over the 2.4GHz and 5GHz bands. What does this mean in real life terms? Simply, it means there are now a lot more open airwaves that routers can use to broadcast Wi-Fi signals. This in turn means faster, more reliable connections from the next generation of devices.

 

This is the biggest spectrum addition in over 30 years – In fact, since the FCC cleared the way for Wi-Fi back in 1989. Pretty huge right? It means the space available for routers and other devices have quadruple the amount in this new spectrum. This means a lot more bandwidth for the user and less interference for their devices. 

 

For the past 20 years we’ve had the Wi-Fi Alliance that oversees the implementation of Wi-Fi. This change in the spectrum is the most ‘monumental decision’ during their existence. You’ll be seeing this implementation as Wi-Fi 6E, with more and more enabled devices becoming available. 

 

Will Wi-Fi 6E fix my bad Wi-Fi? 

 

There’s a good chance that spectrum congestion has interfered with your ability to connect to your Wi-Fi network in the past. When there are a lot of devices all trying to connect over the same band of frequencies, some devices will drop out. Have a look at your local area for Wi-Fi networks – If there is a long list, that could be why you’re struggling with a slow connection and less than favourable reliability. This is because there are too many competing signals, which stops your device getting through. It’s hoped that gains in 6GHz performance will last, even when they are more widely used than they are now. 

 

Not only does Wi-Fi 6E offer new airwaves for routers to use, they are also more spacious airwaves that have less overlapping signals which can cause problems on some other Wi-Fi channels. 

 

The new spectrum doesn’t use any of the previous spectrum, yet offers space for up to 7 maximum-capacity Wi-Fi streams which can all be broadcast simultaneously without causing interference with each other. 

 

Here’s the geeky bit… The UK telecoms regulator, Ofcom, made it possible for home Wi-Fi networks to harness 500MHz of radio spectrum frequency in the new 6GHz band, which will significantly boost the speed of licence-exempt indoor home wireless networks via Wi-Fi 6/6E. 

 

What is 6GHz? 

 

Basically, Wi-Fi works by broadcasting over airwaves that are open for anyone to use. Previously, this was over two bands: 2.4GHz and 5GHz. This third band, 6GHz, is quadrupling the available space for traditional Wi-Fi. 

 

What do the numbers mean? 2.4GHz can travel further, but 6GHz travels faster. The main thing however is that the number of airwaves available on the6GHz band is quadruple what has been available before. Exciting stuff! 

 

On a personal ‘how will this affect me’ level, it means that if you live in a block of flats, and you are the first person to get a 6GHz router, then you won’t be competing with anyone for a connection. The great thing is that even as 6GHz routers become more popular, it’s likely that signals will stay faster and stronger than previously as it’s a more spacious spectrum.  

 

Will Wi-Fi 6E be faster?

 

It’s not quite as straight forward as that, but Wi-Fi 6E will sort of be faster. Theoretically, 6GHz Wi-Fi has the same top speed as 5GHz Wi-Fi. The maximum Wi-Fi 6 standard speed is 9.6 Gbps. Now, you’re not going to actuall get that speed in real life, however having access to the new airwaves could well increase your speed. 

 

The available spectrum at 5GHz means that Wi-Fi signals aren’t as large as they could be. Whereas, it’s thought that routers at 6GHz will broadcast at the current maximum allowable channel size. That in itself, means a faster connection. 

 

These new networks could see smartphone Wi-Fi connections hit 1–2 Gbps. You might be wondering how this compares to 5G – Indeed, these are the speeds expected from millimetre-wave 5G. However, that has very limited availability. 

 

Remember that your internet speeds will also always depend on / be limited by your provider. But it could still be a huge jump for connectivity.  

 

Can I buy Wi-Fi 6 devices?

 

Here in the UK we started to see Wi-Fi 6 devices creep onto the market in the last year or so, once the Wi-Fi Alliance started offering certification for Wi-Fi 6E. Deployment has been slow and steady, with more Wi-Fi 6 enables devices appearing bit by bit. We’re on course for the next generation of Wi-Fi networks.

 

Wi-Fi 6E enabled devices are most seen in smartphones and then tablets, with TV’s likely to follow suit. We use our phones for almost everything, so it’s no surprise that it’s this device that will be top of the list for Wi-Fi 6E. 

 

How do I know if a device supports Wi-Fi 6E?

 

The most widely used Wi-Fi standard on current devices is probably still Wi-Fi 6, the standard previous to Wi-Fi 6E, which you could still see on the box of a new device. This isn’t such a bad thing – It means that the device supports that Wi-Fi standard and offers efficient Wi-Fi performance. 

 

What you should probably start looking out for when buying a new device is Wi-Fi 6E – It’s this one that is extended into the 6GHz band. All devices, like smartphones, tablets, laptops and routers should have backward compatibility – Meaning they will work with any previous Wi-Fi standard to the one that’s stated on the box. This means that you can enjoy available connections even when Wi-Fi 6E isn’t available. 

 

Be aware that even if you buy a Wi-Fi 6E compatible device, you will enjoy the benefits of that when you use it with a Wi-Fi 6E router. 

 

6GHz will become an integral part of Wi-Fi 6 and future generations of Wi-Fi. This means that at some point, you will have to replace your devices with ones that are Wi-Fi 6E compatible to be able to enjoy all the benefits the extra spectrum has to offer. 

 

Due to the Wi-Fi Alliance certification programme, only efficient Wi-Fi 6 devices will be certificated. 

 

It’s worth bearing in mind that the 6GHz spectrum does have some existing licensed users. This means that particularly in outdoor spaces,  Wi-Fi will have to work around them. Outside, routers will need to use something called an “automated frequency control” system. This ensure that they don’t interfere with these existing 6GHz users. Because that means less space to broadcast, there could be degradation of overall performance in some areas.

 

Does Wi-Fi 6E have anything to do with 5G? 

 

We touched on this earlier, but no, they don’t have anything to do with each other really. It just happens that both of these networks are being spoken about a lot, simultaneously. 5G is everywhere, is it not!

 

We keep saying about Wi-Fi 6E being a new spectrum, but really it’s not new, it’s always been there, it’s just been unlicensed. Now, people can use the 6GHz spectrum without a license in their homes. 

 

This also means that other technologies could try to make use of the 6GHz band, which could in turn take up some of the space that Wi-Fi wants to use. 5G is one of the technologies that could be a rival for the space on the 6GHz band. 

 

There is a possibility that 5G could overlap on the new Wi-Fi 6E spectrum through mobile network carriers. This could in turn lead to interference issues, but it’s a bit early to say. If you’re wondering whether 5G will become dominant and replace Wi-Fi altogether, then we think probably not. There doesn’t need to be a winner or a loser when it comes to Wi-Fi 6E vs 5G – They dont necessarily have to be in competition with one another. The spacious nature of this spectrum means there should be enough room for both. 

 

6GHz Wi-Fi is certainly being revered by the tech industry, so we’re pretty hopeful that Wi-Fi will be the main beneficiary of the newly opened 6GHz spectrum.

Enterprise 5G: What You Need To Know 

You may be wondering what 5G means for enterprises. You may well have googled it and landed here! The prevalence of 5G will help to empower businesses – Allowing them to create new experiences and connect in more inventive ways.. 5G will help to change how we work and how we play as well as providing the solution for many problems. Some of them we might not even know about yet! There is a constant buzz in the air surrounding 5G and the excitement of all the possibilities it brings. It might also be causing a bit of FOMO – Businesses will not want to be the ones left behind. 

 

5G is quite often used as a backup for 4G – But those days may soon be over. Businesses will need to start considering using 5G as their primary mobile network, as well as the possibility of using it or their wireless environment – Negating the need for office wiring. 

 

Transformation is happening across all industries – As it tends to do with the introduction of new technology. An ever-changing world! 5G could well be the latest key when it comes to boosting the ambition of your business and increasing the confidence of enterprise customers. 

 

There are 3 main take homes when it comes to Enterprise 5G:

  • This year, the investment in 5G looks strong in enterprises across industries
  • Confidence in the ability to implement 5G successfully is low (only 25% of enterprises feel very confident about effective implementation)
  • Sustainability needs must be met by 5G providers and IoT use

 

The level of current and future spending on emerging technologies is looking healthy, yet there are some significant challenges that industrial 5G needs to overcome. With only a quarter of enterprises feeling confident in their ability to implement 5G successfully, it is vital that 5G providers can help enterprises to get set up. 

 

So what do our 5G providers need to know? Well they need to know what enterprises are thinking when it comes to 5G implementation in order for them to become trusted business partners. 

 

There are several key insights that need to be considered for Enterprise 5G. 

 

Adoption of 5G is not guaranteed


Just because the intention to invest in 5G is there, doesn’t mean it’s a given. The future looks bright in terms of enterprises adopting emerging technologies over the next few years, with investments likely to rise.  The intention to invest in 5G is highest amongst enterprises adopting new technologies. 17% have already invested, and 56% plan to invest in the next 1-3 years. Only 12% are not planning to invest whilst they monitor technological changes.

It seems that organisations are mostly interested in 5G for its use in helping them to meet their sustainability goals as well as improving supply chain management.

This doesn’t mean that 5G implementation is guaranteed. Indeed, just because 5G is becoming more mainstream, doesn’t mean that all organisations are going to stay receptive to it. Asian companies planning to invest in 5G is actually down 10% in comparison to last year.

 

Enterprise 5G Vision Becomes Defensive

 

The mindset towards 5G and IoT is prizing efficiency and optimization instead of entering adjacent markets and driving top-line growth. The top priority of enterprises when it comes to IoT is operational efficiency. Similarly, less enterprises want to spend on IoT for new products and services. 5G application uses for VR and AR seem to be diminishing.

We also need to look at Environmental, Social and Governance consideration as although these are fueling interest in 5G, they are also necessitating new demands on tech providers. Sustainability is a hot topic at the moment, and almost 50% of businesses don’t feel their sustainability needs are being met by 5G vendors.

 

New ways of buying and deploying 5G are well received by enterprises

 

Enterprises seem very receptive to 5G solutions, with over three quarters of businesses interested in using private networks to support the implementation of 5G. Furthermore, 50% of businesses thought that purchasing private network capabilities was an important 5G investment strategy. The reasons being that it provided more control of their network and improved reliability.

It would seem that the lack of confidence in 5G implementation could lead to businesses purchasing 5G through a MVNO (mobile virtual network operator). This implies that the relationship between telecommunications operators and enterprise customers could be in jeopardy. They need to ensure that 5G offerings are offered with easy market strategies.

 

Focus on 5G’s relationship to other technologies, with less attention on cyber risks

 

It looks like one of the top priorities for businesses is looking at the relationship of 5G with other technologies. It would be beneficial for enterprises to receive ongoing information and education on emerging technologies and how they relate to each other for their business needs. Not understanding the relationship between 5G and other emerging technologies could cause challenges.

Rather incredibly, less than a quarter of businesses viewed reducing the risk of cyber threats a priority in terms of IoT and 5G. We cannot stress enough how vital it is for enterprises to design their 5G and IoT deployments with security in mind. This is not a blind spot that can be ignored.

 

Telecommunication operators are falling behind network vendors



Enterprises are supporting their 5G deployments with their technology and telecoms providers, often following selection criteria based on price. Pricing seems to even come above the speed of execution.

It seems that enterprises don’t just want a technology supplier – They want a transformation partner. And who the experts are in this area is fairly evenly split between application and platform vendors and professional services firms. Hot on their heels are network equipment vendors! Less than a fifth of enterprises view telecommunication operators as experts in digital transformation. Whilst trusted as IoT experts, they need to prove their ability to deliver new connectivity transformations.

 

Ambitious ecosystem strategies for enterprises

 

Enterprises are wanting to take advantage of new technologies and ecosystem collaboration is one route towards these new skills and knowledge. Much of their 5 year growth is based within business ecosystem collaboration. There is a growing emphasis on developing cross-sector partnerships as well as shortening the time between new products and services, and revenue. These are ambitious drivers of ecosystem strategies.

Perhaps the most important takeaway from all this is that nearly three quarters of businesses are prioritising suppliers that can offer the relevant ecosystem relationships as part of their 5G capabilities. This means that any 5G provider needs to meet their customers needs and expectations by tapping into these fast-changing corporate ecosystems.

How can I improve my 4G signal speed?

Is there anything worse than slow Wi-Fi or a poor data connection? Waiting for a webpage to load or watching a video b-b-b-buffer. It is so frustrating! 

 

More and more people are now opting for 4G or 5G cellular connectivity in their homes, replacing fibre broadband that’s too slow. Many households are also using 4G/5G connectivity as a back up in the form of hybrid broadband. 

 

Why do people choose cellular broadband? Sometimes it’s because of the price of regular wireless broadband, which can be expensive – Especially in more rural areas where it’s also slow. In these instances, cellular signal if more often than not a faster option. 

 

4G LTE and 5G do have their own restrictions though. Slow data rates on 4G LTE and 5G are also common. But is there a way to improve your 4G signal speed and data rates?

 

How Can I Improve My 4G LTE or 5G Speed?

 

There are three main things you can try to help improve your 4G and 5G data rates:

  1. Update your Device

    If you are using old devices, you may only be connecting to older bands. Using a new phone, tablet, laptop or hotspot could help you to connect to new bands. The newer the device, the more likely they are to support a newer version of the 4G LTe or 5G spec, which would in turn bring you faster data rates.

  2. Try using External Antennas

    Many major carriers have hotspots that support external antenna ports. You may find that using an external antenna could help you to improve signal strength, signal quality and help you access bands that aren’t getting indoors. 

 

  1. You could try a Signal Booster

    The majority of phones (as well as some hotspots) do not have external antenna ports. If you are trying to improve data rates on your phone, you could use a signal booster. They work by amplifying your signal as well as increasing the signal strength of the signal. You can also use them alongside external antennas – They enable the rebroadcast of improved indoor signal.

What configurations can I use to improve 4G / 5G signal strength?

There are a couple of configurations that our Wi-Fi experts would recommend giving a go.

 

1. Latest Hotspot + Directional Outdoor Antennas

 

If you’re happy to use Wi-Fi for distributing your signal indoors, then you can use a hotspot (from your chosen carrier) used alongside external antennas which are mounted on the outside of the building.

Pros

  • If you already have a hotspot, this can prove highly cost-effective
  • Easy to support MIMO (multiple input, multiple output). Using multiple antennas can help improve performance
  • Offers the fastest available data rates
  • Using directional outdoor antennas can help improve signal to interference and noise ratio (SINR) as well as enabling you to access weaker outdoor bands, and improve MIMO performance


Cons

  • It requires a hotspot, with a line of service
  • Your system will be hard-wired. Mobile phones will be able to connect via Wi-Fi but won’t see better 4G/5G signal.

 

  1. 4G LTE or 5G Signal Booster + Directional Outdoor Antenna

 

A mobile signal booster is a great alternative if you don’t have a hotspot, don’t fancy one or simply cannot afford the monthly charges associated with adding a phone line. You may also just want to have wireless 4G / 5G coverage inside, which a mobile signal booster will give you. 

 

A mobile phone signal booster works by amplifying the signal from outdoors and then rebroadcasting it indoors via wireless. Thus getting you the best data rates. 

Pros

  • Provides wireless coverage for multiple devices
  • Will works with existing phones
  • You don’t need a hotspot or extra phone line
  • Using the directional outdoor antennas can help to improve SINR
  • A booster could enable you to connect to weaker bands

Cons

  • Boosters are SISO (single input, single output) with one antenna outside and one antenna inside. This means you cannot use MIMO with this option, and it decreases speeds by approximately 33% 
  • This option can be more expensive than external antennas

 

What can cause slow 4G / 5G data rates? 

 

If we’re trying our best to improve our 4G and 5G data rates, it would make sense to identify what actually causes rates to be slow. There are five main factors that can affect the 4G LTE / 5G data speeds you experience.

 

  1. The Signal Quality (SINR)

    The quality of signal in 4G / 5G networks is measuring in signal to interference and noise ratio (SINR). If you can increase your SINR, you can dramatically improve your data connection speed. As outlined above, you can improve your SINR by using a directional outdoor antenna, which can also be connected to a signal booster or directly to your 4G / 5G hotspot.

  2. The Number of Connected Bands

    Carrier Aggregation is when your phone (or hotspot) is able to use multiple bands to connect to the tower simultaneously. This means that the more bands you are connected to, the higher your data rates.

  3. The Signal Strength (Reference Signal Received Power)


You might be thinking that signal strength must be the most important factor, but it’s actually not. In 4G and 5G networks the RSRP signal strength certainly does matter, but it’s not the most important thing. Check your RSRP – If it’s already stronger than -100dBm, then having a stronger signal won’t help to increase your data rates. 

 

  1. Congestion

    As you can imagine, the more users there are on the tower, the lower your data rate is going to be. The congestion in the tower will also vary by band. In general, lower frequencies penetrate buildings more than higher frequencies. This means that the higher frequency bands are usually less congested. This means that using an outdoor antenna and connecting it directly to your hotspot or signal booster Ican really help you to access the less-congested bands.

  2. MIMO Support

    Using MIMO means that you can use multiple antennas to increase data rates by about 30%. The majority of mobile phone signal boosters are SISO (Single Input, Single Output) but you could install two systems in parallel to get a MIMO booster. 

  3. Throttling

    If you’re with a Mobile Virtual Network Operator, it means that the service provider does not own the wireless network infrastructure. This means that the main carrier’s network may treat your connection like a second-class citizen and find yourself throttled! Throttling may also occur if you use a lot of data per month. Throttling is how the service providers manage the data they provide – They can de-prioritise certain users and even stop their connection going over a certain speed.

 

Get in touch

If you’re struggling with wired broadband, and not getting the reliable internet connection you need in your rural business or home, then 4G / 5G could be a fantastic option for you.

It can feel like a big jump to give up on your wired broadband connection and opt for 4G – Which is where our Cell Coverage 4G survey comes in.

We can tell you exactly whether 4G broadband would work for you, and which network would be most reliable.

 

5G Survey London

With the increasing prevalence of 5G availability across London, you might be needing a 5G survey. Perhaps your London business is moving premises – Or maybe you’re looking to buy or rent a property in London? Either way you need to know that wherever you’re living or working in London will have decent cellular and data coverage. 

Mobile coverage is a huge part of buying or renting a new property – Whether for a business or somewhere to live. 5G mobile phone coverage could be a massive deal breaker if it’s not at the level people have come to expect. 

Thankfully, here at Geekabit we offer a 5G survey in London and the surrounding areas – We know our stuff when it comes to all things wireless. We understand how vital it is to maintain strong connections, whether it’s in the office or at home. 

 

Geekabit’s 5G Survey London

Geekabit offer both internal and external 5G surveys, looking at mobile phone coverage both inside and outside your property. 

You might be wondering – Why would I need a 5G survey? 

For our clients that are wanting to map out the availability of 5G cellular and data coverage in a London office or building, the 5G survey would be a great tool. It’s extremely useful if your organisation is considering moving premises. It is so important nowadays to make sure that you have good 5G mobile phone signal coverage before signing on the dotted line. You don’t want any nasty surprises when it comes to coverage once you’ve moved in! 

Our landlord and estate agent clients also find it a very beneficial tool when it comes to selling or renting out business or residential properties in London. Tenants and house buyers aren’t just looking at the water pressure of the taps or the state of the windows – They’re now asking questions about the strength of cellular reception. Our 5G Survey gives you all the information you need to know. 

People want to make sure that where they live and work in London will have strong 5G mobile coverage. Geekabit’s 5G survey is the perfect way to prove your property has just this and on what networks. 

5G Hybrid Broadband

And where there’s a strong 5G connection, you know you’re covered if the internet goes down. Hybrid broadband is giving customers confidence that even if their standard internet connection fails, they will still have 5G mobile broadband to fall back on.

But this is only as foolproof as your 5G coverage. So before going ahead and investing in hybrid broadband, why not carry out a 5G survey first to make sure that your London property has the coverage you need to fall back on. 

 

Office and homes aren’t the only places where you need a strong, reliable 5G cellular connection

There are many external areas that would hugely benefit from an external 5G survey. Geekabit can also carry out a 5G survey along London roads, parts of the capital’s transport network and throughout leisure facilities in London and the surrounding areas. 

In today’s world, we don’t just stay in one place – Even while we’re working. We take our need for connection wherever we go – And it needs to be strong and reliable. 

Gone are the days where we are tethered to a desk – We need the 5G mobile coverage to be available on the go. Whether we are using a smartphone, tablet or other internet enabled device, we need to stay connected – And we need to know that the signal will be strong and reliable. 

Geekabit’s 5G survey can tell you how strong the cellular coverage is in certain areas of London, and which networks would work best for those locations. This information is invaluable.

 

How do we report the results of our 5G survey?

We can provide results, heatmaps and detailed reports measuring the details of phone coverage for 5G (as well as 2G, 3G and 4G/LTE). 

For any given London location, we can measure: 

  • The cellular connectivity
  • Data upload and download speeds 
  • The occurrence of dropped and failed calls for all the main mobile network operators

Over the last 2 years, companies have realised how vital cellular coverage is – For business operations as well as staying connected with loved ones. This was true before the pandemic, but Covid has certainly increased the need for strong, reliable mobile coverage. 

 

It’s time to invest in mobile enterprise

If you value the importance of the Quality of Service and Quality of Experience of your employees cellular coverage whilst they are at work, then it’s time to invest in mobile enterprise. 

Here at Geekabit, we’ve long been able to provide mobile phone coverage survey results for a fixed point – For example, a particular property in London. 

We can now provide this matched to geolocation data over a moving area, as well as on building plans and maps. When it comes to 5G surveys, this information is really important. 

If your London business has been thinking about investing in further mobile technologies, then our 5G survey is ideal for providing graphical and interactive information, allowing you to really drill down into the data and support and inform your worthwhile investment.

What’s the difference between LTE and 5G?

There has been much hype surrounding 5G, relentlessly for years. Now as part of a global rollout we see 5G available in most major cities as well as some towns and more rural areas. Soon enough, we’ll be using 5G just as we use 4G as the standard.

But 5G is still new to the wireless scene. And for some, the question is – Do we really need 5G when we’ve got LTE?

Many of us are still depending on long-term evolution technology. Indeed, there are only a few areas in the UK that don’t have any LTE presence.

What is LTE?

LTE was first launched back in 2009, and whilst it took a number of years to become part of our national connectivity fabric, it is still now a standard for wireless communications.

The reason for its staying power is down to its reliability and stability – Leading many wireless users to wonder if they even need to move over to 5G.

What is the difference between 4G LTE and 5G?

It was necessary to identify LTE as an element of the 4G standard as many telecoms companies weren’t actually able to provide 4G speeds due to infrastructure. The regulator ITU-R (International Telegraph Union Radiocommunication) established LTE as a standard to show the progress being made towards true 4G.

The download/upload speeds of a particular standard can be different in theory and in practise. Whilst in theory, 4G LTE can achieve data transfer speeds of up to 150Mbps for downloading content and 50Mbps for upload speeds, in practise is is more likely to be 20Mbps and 10Mbps respectively.

These figures will vary depending on:

  • Location
  • Network deployment
  • Traffic

How does 5G compare to 4G LTE in terms of download speeds?

5G connectivity offers theoretical download speeds of up to 10Gbps. A pretty staggering difference! Of course in practise, it may not reach this, but even real-world examples seem to still be dwarfing the speeds of 4G LTE.

Why does 5G reach higher speeds?

5G uses a different spectrum to 4G – Called mmWave which are high-frequency bands. The higher speeds are mostly reached because these high frequency bands support more bandwidth than the ones that LTE uses. This means that more data can be transferred at once.

5G can also use frequencies above low-band but lower than 6GHz. Despite these not supporting the highest possible speeds, they will still outclass 4G LTE. It’s worth noting that 5G coverage could be further expanded by using connectivity below 6GHz, especially as walls and surfaces can block mmWave frequencies.

Basically, 5G uses a different spectrum to 4G LTE and thus:

  • Delivers stronger, faster connections
  • Has a higher capacity for traffic
  • Has low latency (1ms)

Sounds too good to be true doesn’t it! It’s worth remembering that the rollout of 5G is still in its infancy, and therefore coverage is still limited. Before the big networks like EE, Three and Vodafone can deliver the top scope of what 5G has to offer, more work needs to be done.

So should we be choosing LTE or 5G?

As with most techy things, there are lots of factors, such as:

  • Your budget
  • Where you’re based
  • What your connectivity needs are – Personal or business

The more countries adopt and expand their 5G infrastructure, the more 5G-friendly hardware we will start to see. The best way to know whether to choose LTE or 5G is seeing what is on the market and whether it meets your needs.

You may find that some of the 5G devices available don’t have a 4G alternative. You may also find that they are rather on the pricey side! So definitely shop around.

Of course, the more 5G devices we see on the market, the more we will see the prices start to come down. So the time for adopting 5G over LTE may not be quite yet. Patience could also serve you more of the promises 5G has to offer – The more the 5G coverage continues to expand, the higher the speeds and the more consistent the connection to mmWave networks.

Since 2019, we’ve seen prices start to come down as competition in the market starts to heat up, but 5G is still costly. If you have a big budget then you could just go for it now, but we feel like the overall coverage, packages and prices will continue to rapidly improve. We’re inclined to hold out a bit longer and stick to LTE for the time being.

What about 5G for business?

If your business relies on heavily on connected sensors and other similar IoT networks then 5G may be the network you’ve been waiting for. The bandwidth and low latency that 5G could bring to your business cannot be easily ignored.

Think driverless cars navigation and smart sensors – 5G could well be the communications technology that will enable some great and creative deployments.

What are the health concerns associated with 5G?

With 5G comes questions about whether it could harm our health. Do you remember when mobile phones were beginning to emerge into mainstream use and there was much anxiety about what the radio waves were doing to our health? Mobile telephone has never been without concerns, but 5G seems to have evoked more than its fair share of health worries.

The installation of 5G masts have been banned in multiple UK locations. And it’s not just parts of the UK that are opposed to 5G – Back in 2017 180 scientists from 36 different countries made a public appea to the EU to pause their plans of 5G expansion whilst investigations were carried out looking at the long-term effects on human health.

Whilst both 4G and 5G use radio waves, 5G uses higher frequency waves. It’s these high frequency waves that provide better network capacity and speed.

Studies that have looked into any potential health risks from 5G haven’t seemed to identify any specific danger from 5G.

What is the future for LTE and 5G?

With the rise of 5G comes potentially society-changing connectivity – Like self-driving cars.

But technological advances can be slow if not steady. Whilst there is definitely potential for 5G to take over, it could take considerable time for 5G-enabled devices to really take hold of the market. Even from the likes of Apple!

There is still space for 4G LTE in our networks, and whilst it may be 5G’s predecessor, it’s not going anywhere just yet.

Research from Ericsson suggests that the dominant cellular network technology seen in most regions globally is still 4G LTE. 78% of mobile subscriptions in Western Europe in fact! Just because the 5G rollout is well underway, doesn’t mean that everyone will immediately jump ship and drop 4G LTE. It’s expected that 4G LTE will still be the dominant network even 5 years from now.

By 2026 Western Europe is predicted to be using 5G in 69% of all mobile subscriptions. However, Ericssons findings suggest that even as 5G usage surges, 4G LTE won’t automatically decline. It’s even predicted that 4G LTE availability will grow, with global coverage of 95% by 2026, with 5G only seeing 60% in those 5 years.

There is no denying that 5G is the future for telecoms. But by the time we are all accustomed to using it, 6G might well be on the way! Despite 5G becoming more prevalent as time passes, we still think there’s no need to be abandoning 4G just yet.
