Mythbusting: Will the Shutdown of 3G Cause Digital Poverty?

 Have you seen the recent news reports about the withdrawal of 3G by Mobile Network Operators – And how this move will result in ‘millions of people’ being plunged into ‘digital poverty’ by disconnecting them from the internet?

Much of this reporting goes unchallenged and could be seen as scaremongering – Will the consequences of withdrawing the 3G service actually be this dire? 

How much is 3G actually still used? 

3G is actually rather old by tech standards. We’ve had 2 further generations of mobile technology since 3G (4G and 5G, obviously). And 6G isn’t far behind them. 

Can you believe that Vodafone has been using their 3G service for 18 years? What else in the world of technology is around for so long! Vodafone also happens to be the first MNO to start the 3G withdrawal process. 3G data traffic on their network accounted for just 4% in January 2022. In 2016 it was over 30%. 

Did you know that 4G is available to over 99% of the UK’s population whilst they are outdoors? Unfortunately this does fall to between 80 and 87% for geographic coverage. Although, if we’re comparing, 2G only covers 85-93%. We use 2G for basic data like voice and text services. 

When will we lose 3G and 2G services? 

The government, along with all the major mobile network operators, have agreed that by 2033, 2G and 3G signals will be phased out. 

You might be wondering why 3G is being withdrawn first when 2G is obviously older. Well, there are less devices in operation that are critically dependent on 3G services. 4G has been more successful, mainly due to 3G being negatively affected by overpriced spectrum licensing.

2G, on the other hand, is still widely used for basic voice services and limited data for mobiles, as well as other applications like Smart Metres in home energy monitoring systems and similar solutions making it a great low-power fallback option. Therefore, 2G will be around for much longer than 3G. 

The gradual withdrawal of 3G services will differ slightly by mobile network operator. You can find out more information on your mobile operator’s plans to phase out 3G below:

  • Vodafone UK began the withdrawal of 3G at the start of this year and aims to have phased it out by December.
  • Three UK are phasing out their 3G network service gradually over the next 2 years, with it being switched off by the end of 2024.
  • EE are starting their 3G withdrawal by first moving customers off 3G, with a view to switching the 3G network off early next year. 
  • O2 are yet to publicly announce anything but are part of the plans to switch off both 2G and 3G by 2033 and are likely to follow a similar timeline as those above. 

Is the phasing out of 3G a good thing or a bad thing? 

The recent news reports we alluded to earlier would suggest that the withdrawal of 3G services would disconnect a lot of people from the internet and result in digital poverty for millions. But is the phasing out of 3G really a negative thing, like these reports suggest?

Let’s take a closer look at a couple of the worries surrounding the 3G switch off, and hopefully alleviate them.

‘My 4G signal is weak – Will I be unable to access mobile data?’

We can totally see why this would be a worry. If you find that your 4G signal coverage is weak in your area and your handset often falls back to 3G, it makes sense that you would be concerned that you would be disconnected from mobile data altogether once 3G is switched off. Especially if your fixed line broadband was also poor locally. 

What you need to bear in mind is that when the 3G service is switched off, the spectrum that would have been used for that will then be used for 4G and 5G services instead. This means that those who often find their weak 4G signal defaults to 3G, would see an improvement in 4G signal once 3G has been phased out. Happily, this also means that mobile broadband speeds would also improve.  

Of course, this does depend somewhat on the operator itself and their approach in your area. There is a chance that some people could have issues if their operator wasn’t to prepare the updated coverage after 3G is phased out. Let’s remember that that’s not in the best interests of the operator either, and all MNO’s are committed to minimising any problems caused by the withdrawal of 3G services. 

Don’t forget that a weak 4G signal can actually still be better than a strong 3G signal. The data capability available to you isn’t always accurately depicted by how many signal bars you see on your screen. 

It’s also worth noting that current plans for mobile connectivity mean that coverage and performance are only going to improve. The Shared Rural Network, an industry led project worth £1 billion, is working hard to bring 4G to 95% of the UK in geographic coverage by the end of 2025.  

What do the operators themselves have to say about the potential problem of weak 4G signal? 

It would seem that UK mobile network operators are prepared for the phasing out of 3G and the subsequent effects on 4G signal. 

Vodafone says:

“By repurposing the 3G network – we can grow the UK-wide reach of our more energy efficient 4G and 5G networks instead – this means faster data speeds, higher quality voice call services and a chance to continue improving connectivity in previously ‘cut-off’ areas, including rural communities and the London Underground.”

  • They will be optimising their 4G and 5G networks as a part of their phasing out of 3G. In fact, some of their 3G spectrum has already been re-directed as a part of this plan. 
  • They have also contacted customers of theirs who could be impacted by issues once 3G has been switched off. So no news is probably good news! 

Three says:

 “Retiring 3G enables us to repurpose network assets where our customers need them (4G&5G) … this plan has been carefully developed by our network teams to ensure that it benefits our customers.”

  • A tiny 3% of their network traffic was 3G so they expect minimal disruption
  • They believe their customers can expect “faster downloads, better quality streaming and a more reliable experience” when 3G is switched-off.
  • Ahead of the 3G switch off, Three are upgrading many of their legacy 3G sites and repurposing them for newer technologies.
  • They suggest that customers who have a 4G / 5G compatible handset will not be impacted by the phasing out of 3G. 

EE says:

  • Whilst the re-farming of 3G will be a process that takes time, the spectrum used for 3G is planned to be used for 4G and 5G, just not immediately. The locations that have the highest need (those that are congested or at risk of congestion) will be the initial focus for the reuse of 3G spectrum.
  • This operator is focusing on making sure that their 4G has enough capacity to cope once 3G has been switched off. In areas where they have both a 3G and 4G service, the 3G doesn’t generally reach beyond that of their 4G services. They believe they have the tools to identify if any work is needed on spectrum and in what areas so that they can be prioritised.
  • They are currently refreshing their 4G and 5G network and replacing some 5G vendor equipment. They need to finish this network refresh before they can re-farm the 3G spectrum. Once the work has been completed, it will be easier to use the remaining 5MHz from the 3G spectrum. Upgrades will be a mix of remote and site visits depending on configuration. Only modernised sites will be able to re-farm the 3G spectrum to be used for 4G and 5G, hence why the process will take some time. 

O2 says:

Not a lot… Yet! As we said above, O2 haven’t publicly announced their plans to phase out 3G services like the other operators have so it’s all a bit quiet from the O2 camp. 

‘I have an old device that doesn’t have 4G capabilities – How will I get online when 3G is phased out?’

The DPA (Digital Poverty Alliance) is concerned that people with older, more basic devices that don’t have 4G capabilities will fall into ‘digital poverty’ once 3G is phased out if they rely on that device to get online. 

But is this a legitimate concern? Here are some reasons why this may be an unfounded worry. 

  • There are basic phones that have 4G capabilities that have been available on the market for a number of years. They are generally lower cost than more elaborate devices, at around £20-£50 for the handset.
  • Operators often offer bundles with cheap plans and almost free handsets on the more basic models
  • Some operators and charities give more vulnerable users basic handsets for free, so they only need to pay for the tariff

That being said, we realise that there will be people out there that may currently have a device that doesn’t support 4G. There are options out there so anyone who is worried have a shop around – A basic 4G compatible handset and monthly plan for less than £10 a month are out there. 

The best option if you are concerned is probably to ring your current operator and see what they can offer you. 

How Can You Make Sure You’re Not Affected by the 3G Switch Off? 

We’re not saying that nobody will be affected by the phasing out of 3G services. There are always going to be the odd few where unique cases mean that something goes awry. Let’s bear in mind that some handsets will have better reception than others! 

We’re feeling hopeful that the operators will have planned the 3G withdrawal properly and will minimise the impact on their customers. I guess we’ll find out! 

Saying that, here are a few things you can look out for to try and minimise any disruption to your coverage and connections:

  • Ensure your current handset (or any new one you buy) has VoLTE (Voice-over-LTE) capability. Not all 4G handsets can make calls over the same generation of network technology, but if your handset supports the above it will be helpful.
  • Choose a handset that supports Wi-Fi Calling. Whilst not as common on the more basic handsets, if you have a home broadband connection then this would come in very handy.
  • Anyone with a 4G handset having issues after the 3G switch off should perhaps consider changing mobile operator and see if that fixes the problem. Each operator will have different coverage, varying by site, so it might be worth switching around. This also goes for the above – If you have a VoLTE or Wi-Fi Calling enabled handset but are having issues, it could be the operator.
  • Remember that when making calls and texts, 3G/4G handsets will fall back to 2G if having trouble anyway. 

Despite the sensationalised articles about the phasing out of 3G services in headline news, try not to worry. We deal with technological advances all the time in this modern world. You could choose to see the withdrawal of 3G as an upgrade to 4G/5G instead of a negative.

There may well be teething problems for a small percentage of mobile users, but we’re pretty sure that mobile operators will find a solution that works for all when the time comes to switch off 3G services. 

UK Smartphone Users: Are you Satisfied with 5G Mobile Performance?

UK market research provider OnePoll have recently released new survey data suggesting that 80% of smartphone users who use 5G to get online on their mobile are satisfied with the performance. 

80% of surveyed smartphone users satisfied with 5G mobile service

Commissioned by Green Smartphones (a smartphone comparison website), the poll surveyed 1000 UK based adults who use 5G mobile internet on their smartphone. 80% of the respondents reported being satisfied with both the coverage and the broadband speeds via 5G. 

The other 20% of respondents were split between being dissatisfied (8%) and undecided (12%). 

Over 50% say 5G mobile service meets expectations

The poll also asked the selected UK smartphone users whether the 5G they use on their mobile is faster or slower than they expected.

From those surveyed:

  • 53% said 5G mobile speeds were what they expected
  • 21% said it was faster than they expected
  • 12% said it was much faster than their expectations
  • Another 12% said it was slower than they expected
  • The remaining 2% said it was much slower than they expected

Can 5G live up to the hype? 

Recent news outlets have reported disappointment in the rollout of 5G, criticising the 5G mobile services that are available. 

The survey outlined above from OnePoll would suggest different, with the majority of their respondents reporting satisfaction with their 5G mobile service performance. Only a small percentage of those surveyed reported slower than expected 5G mobile speeds. 

As with most things tech, there is always a buzz and excessive hype with the rollout of anything new. Just like 4G and 3G technology before it, 5G services have been hyped up and over-sold with bit expectations for positive impact on mobile performance. 

Has 5G made fixed line broadband obsolete? No. Are we seeing a 5G-powered driverless car revolution on our roads? No, not that either. 

What we are seeing is an upgrade in mobile capability which is useful and appreciated by both businesses and consumers – Once it’s available to them. 

5G wireless network technology

Let’s not forget that 5G technology still has room to grow so further future improvements are likely. 

The expectation is that 5G broadband speed and network coverage will continue to grow and improve over the coming years. 

And, as is the world of tech, once we’ve welcomed and embraced 5G will open arms, attention will turn to 6G and the wild assertions of the benefits it will bring with it.

Which UK City has the Fastest 5G Speeds? 

Opensignal, an independent global organisation who offer reports and insights into the world’s communication networks, have this month published data revealing the UK’s fastest locations for 5G mobile broadband.

The fastest city for 5G download speeds is Birmingham, coming in at 162.7 Mbps. The fastest region was the West Midlands with 151.4 Mbps 5G download speeds. 

Where does the data come from? 

The numbers in this report come from data collected across hundreds of thousands of devices like Smartphones between November 1st 2022 and January 29th 2023. Primary mobile network operators were then compared across different categories. 

Is 5G faster than 4G?

The study also reported on the uplift in mobile broadband speeds when devices went from a 4G to 5G network in various locations. 

The majority of users found 5G download speeds to be between 3.7 to 5.5 times faster than 4G. The biggest uplift was found in Reading, Berkshire where users enjoyed 5.5 times faster speeds on 5G. London however saw the lowest uplift at a rate of 3.7 times faster than 4G.

Is 5G or 4G better in urban or rural areas? 

The report also studied the differences between rural and urban areas when it comes to 5G. You might think that there would be a difference in uplift between these types of areas, but there was actually little difference. For rural areas with 5G, the uplift was 4.7 times faster. In urban areas, the uplift for 5G was 4.5 times faster. 

With this being said, mobile broadband users in urban areas do see significantly faster download speeds on both 4G and 5G networks than those in more rural areas. On 4G networks, download speeds are 23.7% faster (5.8 Mbps) in urban areas. On 5G networks, download speeds are 20.1 Mbps which is 17.6% faster than rural areas. 

5G networks are more limited in rural areas with less coverage. Unsurprisingly, this means that users on a 5G network in an urban area spend more time with an active 5G connection than rural users (9.6% and 6.6% respectively. 

With thanks to OpenSignal for the image 

Where in the UK do users connect to 5G the most?

It will probably come as no surprise that it’s Londoners who are actively connected to 5G networks for the longest.

Unfortunately for us (as we’re based in Hampshire) the South East and South West come very near the bottom of the table when it comes to 5G availability and time spent connected to the network. 

Will mobile network coverage improve in rural areas?

As we mentioned above, the data from this report does reflect on there being a gap between the mobile experience of users in rural and urban areas. 

Thankfully, there is ongoing commitment and work happening to try and improve mobile connectivity in rural areas. 

The UK government and mobile network operators are currently working together on the Shared Rural Network programme to increase the geographic coverage of 4G networks. 

Last year in their 2022 Connected Nations report, Ofcom found that through the SRN and other initiatives, users should be able to get good mobile coverage from at least one operator across 92.2% of the UK. This is a rise of 0.3% from the year before so things are moving in the right direction.

How To Choose and Install an External 4G or 5G Mobile Broadband Antenna

Like with so many of our utilities, we only really notice them when there’s a problem or they’re not working properly. Wi-Fi is just the same! Just like when the power goes out, if your Wi-Fi is on the blink then you know about it – And it is so frustrating! 

Whilst most people are lucky enough to connect to superfast broadband through a wired connection, there are also many rural homes that cannot access and connect to broadband or internet in the same straightforward way. 

Here at Geekabit, we work with lots of people – Businesses and homes – who struggle with the more traditional ways of connecting to the internet and have to turn to mobile broadband through 3G, 4G and 5G. 

And again, many people are lucky to have a business or home within range of a strong enough UK mobile broadband network.

‘Could I benefit from an external antenna?’

There are some more remote rural homes and businesses that find themselves struggling to connect to mobile broadband too. If your business or home is:

– Unable to connect to a decent fixed line ISP 

– Within range of a mobile broadband alternative but find it unstable on various operators

Then you might find it beneficial to get an external antenna installed. But which one do you need? 

Are External Mobile Broadband Antennas Easy to Install?

In terms of actually installing an external antenna, it’s actually pretty straightforward. All you need to do is choose a high, stable location on the outside wall of your house near the roof, and screw the antenna on. Remember to make sure it’s pointing in the right direction (ie. towards the nearest mast). 

You might also choose to mount your antenna on a pole to raise it higher than your house. If you’re going for this option, always make sure that it is stable and won’t cause any damage to the building you are mounting it to. It’s also worth liaising with your local authority before installing a large pole as in some areas, a tall pole could be in breach of planning rules. 

You will also need to drill the cable into the house – It’s very important to avoid any other electrical cables and water pipes whilst you are doing this as well as sealing up the holes afterwards. 

It’s also pretty important to keep the position of your router in mind. Will it be placed near the where the cable feeds into the building? Ideally, the cable between your antenna and router needs to be 5 metres or less otherwise you could find yourself struggling with interference and/ or signal loss. 

If that all feels a little daunting then you can hire a professional installer to do the job for you – Our expert Wi-Fi engineers here at Geekabit can do just this! We operate out of Hampshire, London and Cardiff.  

Whilst the physical aspects of installing an external antenna are quite straightforward, it’s not always easy to choose the right kit. The radio spectrum is variable by nature, which makes it very dependent on your environment. You might manage to install the antenna but not get the outcome you were expecting. 

What antenna you need depends on your specific location and needs. This blog will outline some of the options that could be right for you. Sometimes it’s a case of trial and error to find the right antenna for you – But that’s where it might be best to leave it in expert hands. 

‘Do I need an Omni-directional or Directional antenna?’

When it comes to installing an external antenna, the first thing you need to decide is whether you need an Omni-directional antenna or a Directional antenna. 

Choosing a Directional antenna

If you know where your nearest mast is and have a clear line of sight, then the Directional antenna might be the one for you. Whilst it’s weaker in other directions, the Directional antenna will have higher reception in one direction, hence why it works well for a clear line of sight with the mast or base station. This is often the better choice if you live or work in a rural area. 

What problems can you have with a Directional antenna? 

Using a Directional antenna can run into issues if the station is congested or goes out of service. E.g. during upgrades. 

Choosing an Omni-directional antenna

If you live or work in a more urban, built up area and aren’t sure where the nearest mast is then an Omni-directional antenna could be the better option for you. Whilst they have a lower overall gain, they are able to attract similar reception from all directions. Because the Omni is looking at a wider area, you may find that it provides better reliability. 

Generally, if you are finding and installing an external antenna yourself, then the Omni-directional antenna is probably the one to try first. 

What problems can you have with an Omni-directional antenna? 

It’s possible that because it’s looking at a wider area, the Omni could attract more interference. If you are able to utilise a well positional Directional antenna then you could get better performance that way. 

‘How much power does my external antenna need?’

So you’ve decided whether you need an Omni-directional or Directional antenna. What do you need to consider next? 

You’ll notice that antennas have gain figures in dB / dBi – This is how the power of the antenna is measured. 

In simple terms, the gain of an antenna is the relative measure of its ability to direct radio frequency energy in a certain direction or pattern. What do the gain (dB / dBi) figures on an antenna mean?

We could go into a lot of complicated detail here, but seeing as we’re writing this blog for someone looking to buy and install their own external antenna, we’ll keep it super simple. 

Basically, the higher the gain (dB / dBi) the better the antenna’s performance and range. Obviously, the higher the gain, the more expensive the antenna will cost. 

When you are at this stage of choosing your antenna, it is worth knowing what bands your mobile operator uses so that you can ensure how the different gain values given for an antenna correspond to the spectrum band you will be using. 

‘Choosing an external antenna – What are the challenges?’ 

As we said above, when you are installing a new external antenna, it’s really important to know:

  • Where and which direction the signal is coming from 
  • How strong the signal is
  • Which bands are being used in your local area by local operators

These are some of the biggest challenges you’ll face when installing your antenna. 

‘How can I find out the spectrum information I need to choose an antenna?’

If you go online to mobile operator’s websites you can find coverage checkers (Vodafone, Three UK, O2 and EE (BT)), but these can be rather vague and not always accurate. It’s worth comparing to what Ofcoms Mobile Coverage Checker says too.

Perhaps the best way to identify which bands are being used by your local operator is to download a relevant app or look up the mobile network details on your Smartphone or router. 

These apps will often just tell you the band number for your own operator rather than tell you the spectrum frequency. You’ll find that operators tend to own several bands, but usually use one band for national connectivity. 

What are the most common 4G Mobile Bands in the UK?

800MHz (Band 20)

900MHz (Band 8)

1800MHz (Band 3)

2100MHz (Band 1)

2300MHz (Band 40)

2600MHz (Band 7)

Remember that 5G uses a different band model and is currently only deployed on the 3.4GHz band. 

‘How do I know where my nearest mast is for installing my new antenna?’

So you’ve made sense of the bands on offer in your area from local operators. Next you need to work out where your nearest mast is and whether it’s the most appropriate for your location. Unfortunately it’s not always the option that looks most logical! 

When you’re choosing the most appropriate mast for your use, you need to consider the following:

  • Forms and features of local land surfaces (artificial and natural)
  • Local surroundings
  • Operator choice

There are apps and websites that can help with this such as Mastdata.com and Cellmapper.net. The Opensignal app could also be of use.

Did you know that operators also have sharing agreements with each other? Just to make things a little more complicated. For example, there is a sharing agreement between Vodafone and O2 as well as between EE and Three. What does this mean? Well it means that a mast could be serving more than one operator. 

How do I use signal strength information to position my external antenna?’ 

If you are able to gain an understanding of signal strength in a few different measurements, then you are more likely to position your antenna correctly. 

Signal strength is measured in quite a few different ways, so we’re going to just focus on a few that you are most likely to encounter. These are:

  • Received Signal Strength Indicator (RSSI)
  • Reference Signals Received Power (RSRP)
  • Reference Signal Received Quality (RSRQ)

These measurements are given by a negative dBm (decibel milliWatts) value. In this situation, negative values are actually good (most of the time). They are negative because they represent tiny yet positive numbers on a logarithmic scale, making them easier to consume. For example, -100dBm would be 0.0000000001 mW.

What is a good RSSI signal? Essentially, the closer to 0 dBm, the better the RSSI signal (although it does get more complicated past a certain point with diminishing returns of data speed). An example of excellent 4G RSSI signal would be -65 dBm. A poor RSSI signal would be -85 dBm. 

RSRP works on a similar scale to RSSI, where an excellent 4G RSRP signal would be -80 dBm.  

RSRQ operates on a very different scale, which means that an excellent signal is anything from around -10 dB (not dBm) and a poor signal would be -20 db.

Interestingly, most mobile modems are able to maintain a pretty fast data connection using a poor signal. Problems may arise however in more rural areas where speeds are slower and stability poorer due to the distance from a mast. 

What factors are most likely to affect signal strength? 

  • Distance to mast
  • Interference from competing signals
  • Router band switching
  • Physical obstacles in the environment like buildings, tall trees etc
  • The weather

Of course, these factors are not in your control, but you need to bear them in mind when positioning your antenna in order to get the best signal possible. 

Feeling confident about choosing and installing your external antenna?

If you are about to choose and install an external antenna to improve your 3G, 4G or 5G mobile broadband signal, then hopefully this blog has given you some of the basic information you need to make your decisions.

Can Hot Weather Affect Your Phone Signal?

We’ve recently had the second heatwave of the year here in the UK, particularly the South of England with temperatures exceeding 30 degrees at our bases in Hampshire, London and Cardiff. 

Understatement of the year – It’s been very hot. And you might have noticed that during said heat wave, your 4G mobile phone signal has been affected 

Mobile network traffic is carried on radio waves, so the reception you get on your mobile phone can be affected by any kind of atmospheric conditions – including very hot weather. Just as you might find the weather affects your terrestrial radio signal! 

Weather in general, not just extreme heat, can directly (e.g. a thunderstorm with lightning causing electrical interference) and indirectly (change of season affecting mobile reception) effect 4G signal on your mobile phone or broadband service. 

How could a change of season affect network signal? Well, something as simple as the trees surrounding a property being bare in the Winter could mean that there is less interference to the reception coming in and going out. Come the Spring, the trees become covered with leaves, which could weaken and sometimes block the signal. 

But how does day-to-day weather affect 4G signal?

The most obvious weather affecting mobile phone coverage is stormy weather – Torrential rain and thunderstorms. Water and radio waves don’t really mix, so any water in the atmosphere is not good for your mobile signal. The frequencies used by mobile networks are hindered by any water – Not just rain and snow, but also fog, clouds and even high humidity. All of these types of weather can negatively impact your mobile phone signal. .

Why does water hinder 4G signal? Well, water conducts electricity, so any water vapour in the atmosphere can actually refract and reflect radio waves. Us Wi-Fi engineers call this the “propagation delay effect.”

What this means is that your mobile phone signal could be:

  • Weakened by interference
  • Disrupted or slowed down due to the signal taking longer to go between your device and the tower

Is the weather affecting my mobile phone reception?

We’re going to take a look at different types of weather now, and how each different weather conditional can interfere with the signal you get on your mobile phone or 4G device. 

Do extreme temperatures affect phone signal?

We’ll start with temperature as we’ve been enjoying such hot weather recently! Generally speaking, extremes of hot or cold weather on their own shouldn’t affect your mobile reception. 

You disagree? If you are experiencing issues with your 4G reception during extreme heat or very cold temperatures, it’s more likely to be due to what’s going on in the air and how the humidity is changing. 

Can rain affect my mobile phone reception? 

Rain is the weather that is most likely to negatively affect your 4G signal. In a rainstorm, the density o the water vapour in the air is highest – The heavier the rain, the more likely your 4G will be affected. 

Water vaoour in the air can also absorb the energy from the radio waves, reducing the reception your mobile phone can achieve. 

Can thunderstorms and lightning interfere with my 4G?

We’ve covered rain above, but actually thunderstorms even without heavy rain can cause real issues for mobile phone coverage. Because the lightning causes electrical interference, your 4G can struggle. 

Of course, lightning can also strike causing damage to cell towers and other network equipment which would obviously cause disruption to your local mobile network service. 

Does snow and hail make my mobile signal worse? 

You might think that snow or hail would be worse than rain, but generally it’s actually not as bad for phone reception. Snow flakes and hail stones are less dense than rain, so have less of an effect on mobile coverage. However, if we were to have very heavy snow, it can refract the radio waves and cause them to change direction which would cause problems with mobile signal and 4G. 

Does fog and cloud affect mobile phone signal? 

Whilst not as effective as rain at disrupting 4G signal, fog and cloud can still cause issues for mobile coverage because of the water vapour in the air. They still have the ability to cause localised problems with mobile reception by scattering radio waves. 

Can wind disrupt mobile phone signal? 

Just as with temperature, wind is unlikely to cause mobile coverage problems just as itself and shouldn’t affect your mobile signal if it’s unaccompanied by other weather. 

When it starts to cause problems for 4G signal is when the wind is joined by rain, snow or hail. Of course, with very high winds there is also the possibility of blowing down or damaging mobile network equipment and power lines, which could disrupt the service you get on your mobile. 

Is there anything I can do when the weather gives me poor mobile signal? 

There isn’t a great deal you can do if the weather is affecting your 4G signal and causing mobile coverage issues. You may find that a mobile phone signal booster could provide some reduction in disruption of mobile phone coverage due to poor weather conditions. 

A mobile phone signal booster works by taking the existing mobile signal and amplifying it, giving you better call quality, faster data and a more reliable signal for your phone or home. 

If you rely on your phone for work or use 4G broadband in your home, then this could be a good option for you to help ensure better coverage in bad weather. 

If the odd spot of bad weather isn’t going to cause you too much trouble by disrupting mobile coverage for a short while then you can probably grin and bear it – Ride out the storm! 

How Can I Accurately Check My Mobile Signal Strength? 

Did you know that there is much more to mobile signal strength than just the signal bar display? The real test for measuring your mobile signal strength accurately is the Field Test Mode. The results from this test can help you determine whether you might need a mobile signal booster. 

There are many factors that can affect your mobile signal strength, for example, whether you are inside or outside a building, how far you are from the cell tower etc. So let’s look at the Field Test Mode and how to use it. 

Signal Strength: How To Choose a Mobile Signal Booster

You can’t choose a mobile signal booster for your home or business if you don’t know how strong the outside signal is. And we don’t just mean ‘how many bars you’ve got.’ Yes, that gives some indication of how strong the signal is, but there is a more accurate way to measure mobile signal strength. 

Did you know that different phones have different numbers of bars? Some have 5, some have 4, some even have 8! Not only this, but even when phones have the same number of bars for signal strength, there isn’t actually any standardisation for them. Having 4 bars of signal on one phone can mean something different to having 4 bars on another phone. 

It’s pretty clear that measuring mobile signal strength purely by the number of bars isn’t very specific.

When experts measure mobile signal strength, they measure it in decibels. They are very precise and are much more informative and accurate for doing a mobile signal strength test. Testing in this way means you can find out just how strong the signal is that you are receiving. 

What Is Field Test Mode? 

You may not realise that the majority of phones have Field Test Mode – A built-in setting that can show you very useful information about your phone. This includes the signal strength, measured in decibels. 

We can imagine that you’ve already tried to find this on your phone right this second to check it out! We don’t blame you. But let’s just go through a couple of things to consider before you start taking mobile signal strength readings.

  • Carrier – Remember that the signal strength readings you take are only true for the mobile carrier of said phone. To compare the signal strength to other carriers, you would need phones on those carriers. Basically, even if you get 4 different service providers, you can only test the signal strength of the carrier of your phone when in Field Test Mode. 
  • Network – You need to know if the signal you are measuring is from an LTE network or not in order to interpret the results. LTE readings can be read differently from previous generation networks (like 2G, 3G and 4G0. 

How do you use Field Test Mode on an iPhone?

If you have an iPhone, you’ll find that it has a hidden built-in Field Test Mode app. Follow these steps to access it:

  1. Go to Settings > Wi-Fi and turn Wi-Fi Off.
    You will need the Wi-Fi to be turned off in order to be able to see the network you are connected to (e.g. 3G). 
  2. For iOS 9.3 and above: Go into Settings > Cellular > Cellular Data Options > Enable LTE and turn LTE to Off.
    For iOS 9.2 and below: Go into Settings > Cellular > Enable LTE and turn LTE to Off.
    As we said above, LTE readings can be very different from previous networks. In order to be able to best interpret the results, it’s ideal to get your signal readings from a previous generation network.
    If you like, you could then repeat the site survey with LTE enabled, which would give you readings for different generation networks. 
  3. To launch the Field Test Mode app, go to your Phone Keypad, dial *3001#12345#* and press the Call button. You’ll notice that where before you had signal bars, you now have a negative number. This negative number is the decibel signal strength reading. You should also see the carrier name and the type of network.  
  4. Tap on LTE
  5. Tap on “Serving Cell Meas”
  6. Look for “rsrp0” and the number corresponding will be the numerical measurement of the iPhone cellular signal strength in dBm

To start taking signal strength readings, you need to move to the location where you want to take the reading and then wait for between 30 and 60 seconds for the signal strength readings to catch up. You can record the signal strength, network type and carrier. 

Once you’ve finished taking readings, you can return to your normal iPhone settings by pressing the home button. Don’t forget to go back in and enable Wi-Fi and Cellular LTE! 

How do you use Field Test Mode on an Android?

To access Field Test Mode on an Android follow these simple steps:

  • Go to Settings > “About Phone”
  • Depending on the model of your phone, look for ‘Network’ or ‘Status’ to see your numerical signal strength in decibel 
  • You can usually see Network Type near the signal strength option. 

If you’re after a bit more information, there are apps you can download from Google Pay that will give you the signal strength in decibels as well as other info. To see the available apps search for ‘cell signal’ in the App Store. DOwnload whichever one is compatible with your phone, tablet or device. 

Just like with an iPhone, get ready to take signal readings by moving to the location you want to know the signal strength for. Stop and wait for between 30 and 60 seconds to let the signal readings catch up with you and then you can record them along with the network type (2G, 3G, 4G, LTE etc). 

Keep doing this until you have recorded the signal strength for all the locations in your home or business. 

What would I use mobile signal strength information for? 

Knowing the mobile signal strength for your living or working space enables you to see where you might need to boost the signal. Using Field Test Mode can enable you to perform a site survey, which gives you a floor plan analysis of your home or business.

The purchase of mobile signal boosters (also known as network repeaters, signal amplifiers, signal repeaters etc) should be based on the results of a site survey. 

Carrying out a site survey involves taking several accurate signal strength readings from in and around your home or office building. These readings can help you to calculate whether a signal booster will help and what devices you will need. 

Field Test Mode is ideal for carrying out a site survey. Basing it on signal bars is not reliable compared to the precise numerical value of decibel you get from this tool. Carrying out a site survey using Field Test Mode is very straightforward (as you will have seen from the steps above) and helps you to measure the mobile signal strength of your home or business using just your phone. 

What do the Decibel numbers mean? 

If you are connected to a non-LTE network (2G, 3G, 4G H+), the value you get is the Received SIgnal Strength Indicator (RSSI). This is a method of measuring wireless signals. 

LTE networks however, are usually measured in Reference SIgnal Received Power (RSRP) which is why LTE readings can be very different to the readings for previous generations like above. 

You’ll find that Decibel signal strengths are usually double or triple digits and are marked as a negative number. Your phone might not show the negative sign though. The stronger the signal, the closer the number is to zero, so -89 is a stronger signal that -99. 

The unit of measurement in all this is decibel (dB) – This measures the power of the mobile signal. This value is telling you how strong your phone is receiving the signal from your provider’s mobile network. 

Did you know that the Decibel scale is not linear? If the signal strength increases by 3dB, then it is twice as strong. Signal strength that increases by 10 dB is an increase of ten times the signal strength. So, in real terms, an RSSI value of -50 is actually ten times stronger than an RSSI measurement of -60. 

Why is Field Test Mode so Important?

If you are planning to install a mobile phone signal booster, then it’s absolutely vital that you have an accurate reading of your Received Signal Strength across your business or home. Field Test Mode can help you do just this and inform your site survey ready to help you make the right booster purchase. 

Field Test Mode enables you to see exactly how strong your mobile signal strength is – Both inside and outside your building. 

Field Test Mode is an essential tool when it comes to assessing how a mobile signal booster can improve your reception.
