SpeedScore by Geekabit

Your internet speed has never been so important. Connectivity is as important as electricity, water and gas to a home or business. Decisions are made based on the speed you can offer, yet connectivity is often overlooked until it’s too late.

House buyers, tenants, hospitality customers and even employees are getting more tech savvy and starting to ask questions about internet speeds and reliability.

With a decade of providing connectivity solutions to UK markets, we have launched our innovative Internet Connectivity Measurement Platform.

SpeedScore by Geekabit gives you a variety of tools to help provide an independent certification of your internet speeds and connectivity.

Most internet speed tests are not accurate, as they become affected by the use of Wi-Fi, old devices and different test endpoints. You can’t expect them to provide the same results test after test due to a variety of factors.

Our hardware and software is different, resolving these issues and providing a balanced and independent view. We have no affiliation with any connectivity provider or hardware manufacturer, allowing us to create a truly impartial scheme based on scientific measurement and reporting.

Who is SpeedScore for?
Perfect for Estate Agents looking to prove internet connection speeds in properties for sale, landlords looking to provide accurate broadband measurement for potential tenants, and hospitality hosts giving confidence to those looking for a connected stay.

The Fundamentals of a Wireless LAN

We were going to call this blog ‘WLANs for Dummies’ but that seemed a bit harsh so we settled on the fundamentals of a wireless LAN instead.

A wireless LAN, or WLAN, might seem complicated on the surface but actually it really just follows simple laws of physics. If you can understand these and follow them, then there shouldn’t be any reason why you can’t achieve high performance and scalability for your WLAN.

If you can understand the basics of wireless physics, then you can start to plan your WLAN for a successful deployment. It will also help you to troubleshoot an existing WLAN exhibiting issues.

How Does Data Travel Through a WLAN?

First things first – Let’s look at wave properties.

Data transmits, or travels, from one point to another – e.g. between wireless access points – via electromagnetic waves. This energy travels at the speed of light and operate at different frequencies.

The frequencies of these electromagnetic waves are defined by how many periodic cycles are completed by second.

For example:

How is Frequency Measured?

As we said above, frequency is how many wave cycles are completed per second. This is measured in Hertz. A 2Hz waveform is 2 completed wave cycles in a period of 1 second.

How Does Frequency Affect a WLAN?

A phenomenon called Free Space Path Loss is something that causes signal loss when a waveform travels from one point to another. This is what affects how well data travels across a wireless network.

Different wavelengths (frequencies) experience difference signal loss. The lower the frequency, the longer the wavelength, and the longer the wavelength, the further it can travel before signal gets lost.

For example, 2.4GHz have longer wavelengths than higher frequencies like 5GHz.

How is Wi-Fi Signal Loss Measured?

We measure the energy that is associated with received wireless signals in Decibels (dB). We can also measure loss of signal in this way.

Decibels are logarithmic. On the linear domain, when you add decibels it grows exponentially and when you subtract decibels it reduces exponentially.

The 3dB rule

Every 3dB change, there is a doubling of energy (if increasing) or a halving of energy (if decreasing).

As a ratio, this would look like:

If we had the wireless signal energy at
1:10dB

Then doubling it would be
2:13dB

Remembering this rule can help with both analysing the energy associated with wireless signals as well as predicting it.
Similarly, if you add or subract 10dB, it changes by a factor of 10.

The Relationship Between Frequency and Wireless Signal

Let’s take a look at 2.4Ghz and 5GHz frequencies or waveforms. 5GHz is a higher frequency, so has more wavelengths in a given time period. 5GHz has more wireless signal loss (attenuation) than 2.4GHz, and thus is better for high-density areas. 2.4GHz has less wavelengths in a given time period and is better suited for wider coverage. Bear this in mind when you are planning or troubleshooting a wireless network.

How is Wireless Signal Affected by Different Materials?

In an ideal world, you would have a clear line of sight between your wireless points. In reality, this is rarely the case and you will often find things that get in the way and stop the wireless signal from traversing effectively across your network.

Different materials will affect wireless signals and attenuation in different ways.

Materials such as concrete will cause more attenuation of wireless signal than wood.

In scenarios where wireless signals can propagate (the action of spreading) normally, there is no interference from other materials. However, there are some things that can alter the propagation of a wireless signal, causing it to behave differently and potentially become unreliable.

For example, a WLAN environment with metal surfaces may encounter unpredictability with wireless signal due to it reflecting off the metal.
Wireless signal can also be absorbed by certain materials like water or people, causing the signal to falter.

Being mindful of materials during the WLAN planning stage can help ensure the environment doesn’t hinder your wireless network and you have reliable connectivity results.

Co-Channel Interference

Different materials aren’t the only thing that can interfer with wireless signals.

Due to the 2.4GHz and 5GHz frewuency bands being unlicensed, there are no restrictions on people when extending wireless networks with access points.

This means that they can become crowded as well as channels not being assigned efficiently. Both of these issues can cause co-channel interference.

When planning your WLAN it’s important to take these issues nito consideration and plan your wireless network accordingly so as not to risk problems with wireless signal later down the line.

You want your WLAN to be as effective and efficient as it can possible be, which takes planning and wireless network knowledge.

Whilst the 2.4GHz is popular due to its propagation qualities due its waveforms passing through materials like walls more easily and reaching end users at a long distance. This however has meant that its become crowded with competing devices such as cordless telephones, baby monitors and bluetooth devices. This saturation can cause problems with your wireless signal.

In comparison, the 5GHz spectrum has greater availability and relaxed transmission power giving it more flexibility when it comes to wireless networks.

The 2.4GHz band has only 3 channels without any overlap, whereas the 5GHz has 24. This is another reason why the 5GHz band is favoured for high-density WLAN environments.

Understanding Frequency Channels

To ensure you can maximise the performance and scalability of your WLAN, you need to understand how these channels operate and use that knowledge to avoid co-channel interference.

Let’s take an Access Point as an example. An AP will have a specific bandwidth through which it will transmit and receive signals to and from other points. The channel assigned to the AP will be appropriate for the centre frequency of the first 20MHz channel used by the AP.

This bandwidth is specifically the frequency range over which the data signals are transmitted. Peak transmission and power is spread over the range of that bandwidth, with it dropping off at the edges.

These edges are then at risk of meeting other nearby wireless networks and are prone to interference from the ‘noise’ of these other networks.

It’s important to use what you know about channels to prevent the reduction of wireless signal speed and loss of scalability of your wireless network.

In order to minimise interference between neighbouring access points, choose to assign them with non-adjacent channels. Following this will make it easier to scale your network. If you don’t follow this principle, you will likely encounter problems with latency and throughput.

The best way of reducing interference when assigning WLAN channels is to carry out a Wi-Fi site survey. This involves analysing the noise levels across the spectrum so you can make informed decisions for your wireless network.

What’s Different About Wi-Fi 6?

Wondering what all the fuss is about when it comes to Wi-Fi 6? If you’re questioning what the differences are and whether it’s worth making hardware device changes, then read on.

The next generation of wireless standard is here (actually, it’s been here since the end of 2019). Wi-Fi 6, or 802.11ax has the following main differences:

  • It’s faster
  • It provides better performance in congested areas (think anything from your own device-packed home, to stadiums)

We know it informally as Wi-Fi 6 – Wi-Fi versions have now been assigned simple numbers to replace the more complicated code-like names that we saw before.

What are the Wi-Fi Version Numbers?

The new Wi-Fi version numbers are much more user friendly, but for the fellow geeks among us, here are what the new version numbers correspond to, plus (whilst not being officially branded) what all of the old versions would have been.

Wi-Fi 1 – 802.11b (released in 1999)

Wi-Fi 2 – 802.11a (also released in 1999)

Wi-Fi 3 – 802.11g (released in 2003)

Wi-Fi 4 – 802.11n (released in 2009)

Wi-Fi 5 – 802.11ac (released in 2014)

Wi-Fi 6 – 802.11ax (released in 2019)

You might start to see these newer version numbers appear in software when connecting your smartphone, tablet or laptop, to enable you to see which Wi-Fi networks are newer and faster. This is what the Wi-Fi Alliance announced that they would like to be seeing across networks. It’s worth noting that it isn’t mandatory for manufacturers to label their products with Wi-Fi 6 instead of 802.11ax, but we’re hopeful that most will. Re-naming products from 802.11ac to Wi-Fi 5 might be another matter though!

Wi-Fi That’s Faster

As with most technological advances, the latest development in Wi-Fi standard is faster in terms of data transfer speeds. In comparison to Wi-Fi 5, a Wi-Fi 6 router would provide one device with up to 40% higher speeds.

What Makes Wi-Fi 6 Faster?

The reason Wi-Fi 6 can achieve such faster speeds is due to more efficient data coding which thus results in higher throughput. Basically, the radio waves are packed with more data. With each Wi-Fi standard, the ability for the chips to encode and decode the data gets more powerful, hence why Wi-Fi 6 is faster than Wi-Fi 5, and can handle extra work.

You may be aware that we have 2 frequenceis used for networks – 5GHz and 2.4GHz. 5GHz is more commonly used as it is subject to less interference, however 2.4GHz is still a good option for being able to penetrate solid objects. Wi-Fi 6, the new standard, even increases speeds on these 2.4GHz networks.

How Will Wi-Fi 6 Affect the Battery Life on my Device?

Many Wi-Fi 6 enabled devices will have a new ‘target wake time’ feature. This means that an access point can define a specific set of times when devices connected to the internet need to have access to the wireless network. This new efficiency should mean that your Wi-Fi enables devices should have a longer battery life.

Let’s take your smartphone, for example. When the AP is talking to your phone, it can tell it when to put it’s Wi-Fi radio to sleep and when to wave it up to receive the next transmission. Because your device can spend more time in sleep mode, you should find your battery lasts longer.

It also means that devices that connect via Wi-Fi with lower power can benefit from longer battery life.

Wi-Fi That Performs Better in Crowded Areas

We know there hasn’t been much opportunity for it as late, but picture trying to get online at an airport, hotel or live event at a stadium. When an area is as congested with devices as these, you can suffer with slow Wi-Fi and even struggle to connect.

Wi-Fi 6 tackles just this problem. With new technology, superior to previous Wi-Fi standards, it’s purported that Wi-Fi 6 will improve the average speed of each user by at least 4 times. Even in crowded areas with lots of devices.

This isn’t just something that will benefit you when out in public places – It could be a huge help in your home as well. If you have a large family all with multiple devices connected to Wi-Fi, then this could be just the solution to stop the slow-down. Or perhaps if you live in a densely populated place, like a block of flats.

How Does Wi-Fi 6 Tackle Congestion from Multiple Devices?

There are various features that help Wi-Fi 6 better tackle the problem of heavily crowded networks. Just knowing that a Wi-Fi 6 device connected to a Wi-Fi 6 access point will work better may well be enough for you!

For those who want all the geeky details, here’s what’s going on to make Wi-Fi 6 better for networks with multiple or many devices.

Wi-Fi 6 technology is able to create a large number of sub-channels within one wireless channel. Date intended for each individual device can be carried by each sub-channel. This technology is called Orthogonal Frequency Division Multiple Access (OFDMA). Essentially this means that a Wi-Fi 6 enabled access point can talk to more devices at once.

Wi-Fi 6 also has improved MultipleIn/Multiple Out (MIMO). Again, this lets the access point talk to multiple devices at once through multiple antennas. The difference between this and Wi-Fi 5, is that while the latter enabled an access point to talk to multiple devices at the same time, it couldn’t allow the devices to respond at the same time, thus slowing things down. The new improved MIMO on Wi-Fi 6 is a multi-user version (MU-MIMO) which enables devices to respond to the access point at the same time.

Let’s look at another potential scenario. Wireless access points that are locating close to one another may transmit on the same channel. This means that the radio needs to listen and wait for a clear signal before it can reply. Wi-Fi 6 uses spatial frequency re-use which allows you to configure Wi-Fi 6 wireless access points with different Basic Service Set (BSS) colours, which consists of a number between 0 and 7. The device can then determine whether a particular channel has a weaker signal, and thus ignore it and transmit without waiting. This is another way in which Wi-Fi 6 will improve wireless performance in congested areas.

These are just a couple of the improvements to be seen from the new Wi-Fi 6 standard. There are many more, smaller enhancements which will improve the speed and performance with Wi-Fi 6.

How Do I Know If Something has Wi-Fi 6?

Luckily, thanks to this handy article, you’re now familiar with all the technical names of the different Wi-Fi standards, so you’ll know exactly what to look for. Right? Don’t panic! We’re only kidding. Thanks to the new versions, it’ll be easy for you to find devices that are certified Wi-Fi 6 (rather than hunting around for 802.11ax!). Device manufacturers are able to say whether their product is Wi-Fi 6 or Wi-Fi 5.

You may also start to see a logo saying ‘Wi-Fi 6 Certified’ on relevant devices. This means that the product has gone through the Wi-Fi Alliance’s certification process. The old Wi-Fi Certified logo simply told you it was Wi-Fi Certified, rather than what generation of Wi-Fi a product was. The new logo will make it clear if it is Wi-Fi 6. So there will be no need for trawling through product specifications!

When Can I Get Wi-Fi 6 Enabled Devices?

The new Wi-Fi 6 standard was finalised in 2019, with hardware being released in the latter part of the same year and into 2020. So you should be seeing Wi-Fi 6 enabled products in the market now. It’s shouldn’t be something you need to put too much thought into – As new routers, smartphones, tables and laptops are released into the market, they will just start to come with this new Wi-Fi 6 technology.

It’s worth remembering that to benefit from the improvements on the new Wi-Fi 6 standard, you need both the sender and receiver devices to support this latest generation of Wi-Fi 6. Whatever the connection, it will only operate in the mode that your device supports. For example, you may have a Wi-Fi 6 enabled router, a Wi-Fi 6 enabled smartphone, but a laptop that only supports Wi-Fi 5. You’ll see the advantages of Wi-Fi 6 on your smartphone, but the laptop will only work at Wi-Fi 5 capacity.

Could 4G Broadband Be The Answer to Threat of BT Strike?
Working-From-Home Fears Due To BT Strike

For the first time since 1987, BT are facing nationwide industrial action due to a ballot regarding job cuts and site closures. The Communication Workers Union is due to hold a ballot soon, which could have an enormous impact on the network if a yes vote is returned.

Through this ongoing pandemic, effective internet has kept us connected with colleagues as well as loved ones. It’s held businesses together through the rise of working from home, and it’s kept part of the economy going throughout lockdown restrictions. As a nation, we’ve realised how vital a good internet connection is.

Most of the UK’s broadband network consists of BT, EE and Openreach, serving millions of homes across the nation. If, in late Spring, a strike goes ahead this could mean big problems for people who are working from home and reliant on their broadband connection.

Assuredly, they will only strike if they feel they absolutely must – They don’t want to disrupt services across the country to people’s internet unless they feel they have no other choice to protect their workers and service.

What does the possible BT strike mean for those working from home?

Nationwide industrial action by BT staff could have a huge effect on those working from home, who are relying on a dependable internet connection. Is there anything worse than trying to get some work done with a slow internet connection, or a meeting via video call dropping out every 2 minutes?

The pandemic and lockdown restrictions has meant that almost 50% of the working population have been working from home during the pandemic (ONS).

These workers are relying on their home broadband connection to be able to continue doing their jobs.

As we’ve seen from the challenges of home-learning and home-working, those who are currently based at home need a connection that can support both upload and download speeds in order to partake in video conference calls like Zoom, Microsoft Teams and Google Meet.

Not only is home internet needed more than ever, but the quality of the connection is also more vital then it has been previously.

What alternatives to Wi-Fi would be unaffected by a BT strike?

If you are worried that your home internet connection could be affected by the posed threat of BT industrial action, there are thankfully alternative methods of getting internet into your home.

We have seen an influx of 4G broadband installations and enquiries. Whilst these have mostly been from areas in rural Hampshire where standard internet connections are unreliable and slow, 4G broadband is an excellent way of backing up your existing internet connection.

Why 4G broadband?

4G broadband is the idea solution to patchy, unreliable Openreach internet connections. It can also be an excellent back-up solution should your standard Wi-Fi connection go down or become unavailable.

4G signal is received via an external 4G antenna and emitted into your home through a 4G router using a sim based data plan.

Here at Geekabit, we have a 4G testing pole so that we can accurately estimate 4G internet speeds in your location before installing a new antenna and router.

How could 4G broadband help if my internet is affected by BT industrial action?

Our expert Wi-Fi engineers are skilled in providing 4G broadband services for hire. We are experienced in providing an ideal internet solution for scenarios such as building sites, TV filming and temporary cabins. It’s also a great interim option for people moving house and between service providers when they first move in to their new home.

This makes 4G broadband the perfect alternative if your internet was to be affected and your home-working situation compromised.

If you would like more information on our 4G broadband hire options, please don’t hesitate to get in touch with one of our Wi-Fi experts here.

If you are already experiencing internet problems in a rural area, then 4G broadband may well be the answer. You may be interested in previous blogs we’ve written regarding this – Or for more information, please see our website.

4G Broadband – The Answer to Your Rural Wi-Fi Woes?

Over the last year, we’ve been inundated with requests from people looking for a different and more reliable source of broadband service.

Many people are moving out of London into more rural areas and expecting the same internet connectivity as they would have in urban areas.

They soon realise that many parts of the countryside are suffering from a broadband deficit and there’s a connectivity imbalance across the countryside.

We’ve installed countless numbers of external 4G antennas and routers, effectively replacing the broadband through the telephone cable, with a data SIM card.

This simple solution has meant that people who couldn’t Zoom for work at home now can, children can do their schooling online through Google classroom and Teams, and the dreaded buffering of Netflix binging no longer happens.

Not only is this solution perfect for those at home, but it works excellently for temporary offices too, such as those in construction, archaeology and film and TV work.

We thought we would share a couple of case studies from some recent 4G installations that have seen a hugely positive affect on their connectivity since making the switch.

 

Case Study – A Rural Home in Bishops Waltham

Wi-Fi Issue: This charming rural home in Bishops Waltham struggled with only 2-3mb download speed and 0.5mb upload speed through their BT Openreach line. As the Director of a large London bank, this unreliable connection meant she couldn’t work from home.

Our 4G Broadband Solution: We installed a 4G antenna and router, and she’s now getting perfect 60mb download speeds with 20mb upload speeds. This means she then didn’t have to travel into London so often.

Case Study – A Garden Landscaping Company in New Alresford

Wi-Fi Issue: This garden landscaping company recently moved their office to a rural location without any internet or traditional phone line. Their new office was a converted shipping container which, as it is made of metal, meant that their phones wouldn’t work quite so well for internet speed.

Our 4G Broadband Solution: Our 4G external antenna solution means they now get 40mb download and 20mb upload speeds within their new office.

Case Study – A Large Metalwork Company in Rural Dorset

Wi-Fi Issue – This metalwork company was having trouble with 3-5mb download speeds and less than 1mb upload speeds. This was the maximum possible speed in their area. Having asked  BT Openreach to extend fibre to their premises, they found out it would not only have cost them hundreds of thousands of pounds, but also ruined a beautiful part of the countryside. (If you watch The Crown you may well have seen it!) The poor internet connection meant that contacting their London based clients over Zoom was very difficult, and often required them to do so from their home instead or office.

Our 4G Broadband Solution: Using our 4G router and external antenna, they now receive 70mb download speeds and 30mb upload speeds. This means they can now easily maintain contact with their clients without having to travel back to their homes for a good quality Zoom call. It also means they can employ more people onsite and increase employment in the local community without moving their office to a larger town.

 

If any of these problems seem familiar to you, whether it’s your home connection or business, perhaps now is the time to get in touch and let us see if we can help.

These 3 examples are just a handful of the successes we’ve seen from clients moving from a slow BT Openreach connection to a faster 4G broadband option.

 

How can you be sure that 4G broadband is the right option for you?

It’s okay to feel nervous, we understand how frustrating a slow connection can be. We can come and assess your property to see whether a 4G broadband option would be viable for you with our new 4G antenna testing pole. This bit of kit means we can get an accurate representation of how our 4G routers and eternal antennas can solve your broadband connectivity problems.

For more information on our 4G broadband service, head to our website. You can also get in touch with one of our Wi-Fi experts who will be happy to discuss your requirements.

 

Don’t let a slow BT Openreach connection hold you back. Whether it’s for Zoom calls to keep in touch with colleagues, WhatsApp video calls with friends and family, or nightly Netflix binges – You deserve a connection that doesn’t freeze, buffer or drop. Call in the Wi-Fi Experts today.

Do you know the difference between mbps and mb?

Data and download speeds are all that we barter for when it comes using the internet nowadays. How much data you have is all the phone companies have left to reel you in with on a new offer. Lets break it all down and look at what the differences are.

A bit is the fundamental unit of information that we use in our computing and also in communications. The word ‘binary digit’ is shortened to form the word ‘bit’.  Therefore, we use bits in all our binary digit computations. The computation and communication here mean the digitals ones.

A byte is the unit of information that is used in digital fields and is equals eight bits. We generally address the memory spaces in terms of bytes and it forms the smallest addressable unit of memory space that is been used in computer related technologies. It is referred as ‘B’ in the digital electronics and we should note that it forms the different notion from that of a bit. So an eight-bit can also be called as a byte or simply with ‘B’.

Notions for Bits and Bytes:
We shall write the above-mentioned notions here, to understand it better.

1 bit = is denoted as ‘b’.
For example, it can be written as 1 b.
It’s bit length = 1.
1 Byte = 8 bits is denoted as ‘B’.
It’s bit length = 8.

The capitalisation of alphabets means a lot in these notions. A bit is simply written as ‘b’ whereas a byte is written as ‘B’. As already noted, what they are and what values they can hold. The letter ‘m’ here means Mega. The value 10is noted simply as Mega so that we can use it in our digital computations with better understandings. When we find a notion as ‘mb’, it means megabits and ‘MB’ means Mega Bytes. So noting the capitalisation of the betters can mean a lot.

The abbreviation ‘mbps’ means megabits per second and it is always used to denote the speed of transmissions. You might have heard it when you opted for a broadband connection. This is what you are sold your broadband on and what you are sold and what you get are two very different things. You can always check the download and upload speeds you are getting online.

Hopefully this will arm you with the information to help you make better decisions in understanding the differences between mbps and mb.

Wi-Fi Frequencies: An Overview

With all of the current and future Wi-Fi frequencies and technologies are really getting confusing, with that in mind theres actually more than you realise. So let’s take a look at what’s out there and what’s coming up, as well as trying to make it as simple as we can.

There are two common well known dominant Wi-Fi frequencies used by 802.11a/b/g/n systems, 2.4 GHz and 5 GHz. Almost all modern Wi-Fi devices are made to operate in one or both of these frequencies. These frequencies now dominate most of our homes.

The same basic OFDM technology used by 802.11a in 5 GHz is also used in a 4.9 GHz public safety band. This band is 50 MHz wide it requires a license and is only available in some regulatory domains. There are specific and limited purposes for this band so you won’t see a lot of commercial interest or attention here.

The FCC also opened up 50 MHz of bandwidth in a 3.6 GHz licensed band. OFDM is used here as well. In the US this band requires a license but usage is not limited to certain technologies, so the band will be shared.  There aren’t many benefits to this frequency band and the interference avoidance requirements represent a moderate R&D requirement without much ROI.

You’ve most likely heard about this PHY spec in development. It builds on 802.11n MIMO technology in 5 GHz and seeks to expand on the HT PHY with a few developments that are a natural next step. 802.11n gave us 40 MHz bonded channels. 802.11ac will give us 80 MHz channels and, likely, 160 MHz channels.. 80 MHz bandwidth will get us past the gigabit rate threshold. MIMO will also be expanded to 8×8, but since client devices aren’t adopting that type of power hungry radio anytime in the near future (or ever), 8×8 will be used for MU-MIMO. MU-MIMO allows an AP to transmit simultaneous downlink frames to multiple users (MUs).

VHT 60 GHz (802.11ad) — This PHY opens up a fresh use case for Wi-Fi in the form of very high throughput at short range. There are a lot of challenges getting the kind of range that would be useful to enterprises. We’ll see short-range, high bandwidth applications, but there are still failings to see the exciting benefits that have been touted in the press.

White-Fi (802.11af) — The TV whitespace frequencies between 50 and 600 MHz have also created some exciting buzz in the past several months. There are many articles out there discussing the limitations and benefits of this band. The main issue with this frequency is that contiguous bandwidth is in short supply, so we see a handful of 6 MHz-wide channels, which will yield lower transmission rates than 802.11a/g. The merits of a low frequency are fairly well known; that is, despite the throughput-deficient bandwidth, the range and coverage is advantageous. Rural broadband applications are the evident winner with this technology where coverage is more important than bandwidth and high user density.

It is also worth mentioning 900 MHz. Back in the 1990s, 900 MHz was a popular pre-802.11-Wi-Fi frequency. It is an unlicensed ISM band. This is a semi-popular broadband frequency with decent range and limited throughput. Many vendors use proprietary PtP and PtMP solutions here for wireless distribution, but they are not defined by 802.11 and they are not designed for client access.

Wi-FI frequencies in brief:

  • 50-600 MHz TV Whitespace — Good range, low capacity.
  • 900 MHz — Proprietary PtP and PtMP. Decent range, slow rates.
  • 2.4 GHz — Well-known and used.
  • 3.6 GHz — Little-used, licensed band.
  • 4.9 GHz — Licensed public safety band.
  • 5 GHz — Well-known and used, the future of Wi-Fi.
  • 60 GHz — Short range, very high throughput.
Siklu EtherHaul-2X00 Series

1 Gbps connectivity between two sites is sometimes necessary and an E-band set of radios that work within a 70-80 Ghz frequency is a viable solution.  The benefits of these radios are vast and varied.  Being relatively cheap makes them popular and this coupled with the fact that they are easy to deploy and manage makes them a Wi-Fi winner.

Siklu have created a solution in an E-band set of radios that will provide 2 Gbps connectivity over up to 7kms.  This wider channel width solution is able to work at lower modulations which makes it a great option compared to others on the market.  The EH -2X00 delivers 2Gbps full duplex point to point wireless connectivity making it robust and futureproof.

Being small in size, the tiny footprint allows easy site acquisition and an easy installation.  Moreover, the E-band spectrum is uncongested and offers a quick licensing process compared to other options.  Spectrum protection is maintained whist the cost is still relatively cheap.

The EH-2X00 series offers a great price per MB but alongside this its lower installation costs make it unbeatable in price.  The new model is based on an evolved version of a Siklu’s field proven platform making it extremely reliable.  This reliability cuts the cost of site visits which contributes to its exceptional value for money.

With 16 non-overlapping channels available to it, the EH-2X00 is able to deploy dense networks over greater distances and offers a great solution for those looking for 1Gbps between 2 sites.

Coffee shop cyber-security – how high is the risk?

It’s fair to say that the media has a way of taking an idea and running with it, which can often create hysteria.  This week we’ve been reading a lot of stories about internet security in public spaces and have been questioning the findings.

 

Ipass have just published their 2017 security report and the findings have been interesting.  Coffee shops have been flagged up as public networks where hackers can most easily access other people’s data.  The findings stated that CEO’s present the greatest security risk to businesses as they are often working remotely and therefore connect to public wi-fi which could pose a risk.  Of course, CEO’s are in possession of valuable information and so the risk to a business could be colossal. Interestingly, the report states that many organisations have stepped up their security measures and don’t allow employees to connect to public networks due to concerns about internet safety.

 

These findings have not only raised questions for businesses but have also raised questions about our everyday safety and how reliable public wi-fi really is.  However, there are ways to ensure that you are always secure.  VPN’s can help to create a safer connection by encrypting information travelling to and from a device.  Using a VPN can inhibit these attacks and keep your information safe so we thoroughly recommend looking into that as an option.  The reports are interesting and raise valid points about cyber security.  However, it’s always worth bearing in mind that there are ways to reduce your risk.  Get in touch to find out more!
