What is 3G, 4G, and LTE - and Why Should I Care?
If you own a smartphone, you undoubtedly have heard the terms 3G, 4G, and LTE. Cellular providers such as AT&T and Verizon continuously advertise they have biggest or fastest 4G network or LTE network. It’s difficult to understand how each company can make those claims. However, when buying a new smartphone, it is important to understand the difference. The type of data network can directly impact the performance of your smartphone.
When you buy a smartphone, you are typically required to sign up for a service plan that defines a certain amount of calling minutes and data usage. Once connected to the cellular provider’s network, the smartphone can communicate with the outside world to support features such as email, maps, and Internet browsing. Many of the smartphone apps rely on sending and receiving data across the network.
When describing smartphone data networks, you commonly hear the terms 3G, 4G, and LTE. This refers to the generation of network technology. The third generation network, known as 3G, is the oldest technology of the group. 4G is the fourth generation data network and LTE stands for Long Term Evolution. The basic difference between them is the speed of the network. When selecting a smartphone, the older models may not support the newer data network technology. It is important to select a model that supports a data speed appropriate for your needs.
The 3G network was the first technology with sufficient speed to provide a decent user experience on a smartphone. There were some smartphones that used the older 2G EDGE technology, but the data speeds were slow and the user spent a lot of time waiting for data to load.
Each of the major cellular providers have 3G networks that provide coverage across most of the country. There are two competing 3G technologies currently being used: Global System for Mobiles (GSM) and Code Division Multiple Access (CDMA). AT&T and T-Mobile use the GSM technology while Verizon and Sprint use the CDMA technology. Since the technologies are not compatible with each other, this is the reason you can’t use a Verizon phone on an AT&T network (or vice versa).
4G and LTE
The 4G technology is the successor to the 3G technology. Cellular providers are still building out their 4G networks. Theoretically, 4G is much faster than 3G. But before we start comparing 4G speed to 3G speed, it is important to understand there are different versions of 4G.
When talking about 4G, things can get a little confusing. Basically, there is 4G and 4G LTE. Many people consider LTE to be true 4G technology. Generally, if a cellular provider describes a 4G network without mentioning LTE, they are probably talking about a High Speed Packet Access (HSPA) network. The HSPA network is a faster version of the 3G GSM network. While not as fast as an LTE network, it is still faster than a 3G network. Since LTE is still relatively new, the cellular providers haven’t fully built out their LTE networks yet. Be careful when looking at the network coverage maps on the providers’ websites. Some companies claim to have broad nationwide 4G coverage. They may really be talking about HSPA coverage and not LTE coverage.
In theory, LTE can be up to ten times faster than 3G. In practice, the actual network speed will vary based on network load and signal strength. Even if LTE does not meet its theoretical speed, it is still much faster than 3G. Activities that require large amounts of data, such as streaming movies, work very well on an LTE network. If you plan to perform a lot of data-hungry activities or simply want the best performance when surfing the Internet, you should really plan on buying a smartphone that supports LTE.
What iPhone Models Support LTE?
If you are considering buying an iPhone, you will find five models available: iPhone 6s Plus, iPhone 6s, iPhone 6 Plus, iPhone 6, and the iPhone 5s. All these models support LTE. The iPhone 5 was the first model to support LTE and all models newer than the iPhone 5 support LTE. The iPhone models prior to the iPhone 5 do not support LTE. The iPhone 4s supports HSPA, which some cellular carriers call 4G. The iPhone 4 will only support 3G networks.
This page on the Apple website compares all the current iPhone models.
When buying a new smartphone, don’t be fooled by all the marketing hype about 4G and LTE networks. Understand the different network technologies available and try using the Internet on the smartphone before you buy. The LTE technology provides the fastest cellular data network available and the speed difference between LTE, 4G (HSPA), and 3G can be quite noticeable.

4G vs LTE: What's the Difference?
4G, LTE, LTE-A, carrier aggregation. It's all tech nonsense if you don't understand what the jargon means. Here we explain the differences between 4G and LTE so you're better equipped to choose not only the best phone, but also the best tariff.
These days, there are a lot of decisions to make when getting a new phone. Along with deciding which handset is best for you, you might also have to choose a new tariff, and that's a complex business in itself.
4G is the big buzzword you'll hear or see, but what exactly is 4G? Is it the same as LTE? In a word, no, but phone manufacturers and mobile operators love to use them interchangeably, and further muddy the waters with dumbed-down marketing materials.
In this article, we'll explain everything you need to know about 4G, the speeds you can expect to get and equip you to choose a phone and tariff that's right for you.
What is 4G?
The International Telecommunications Union-Radio (ITU-R) is the United Nations official agency for all manner of information and communication technologies, which decided on the specifications for the 4G standard in March 2008.
It decided that the peak download speeds for 4G should be 100Mbit/s for high mobility devices, such as when you're using a phone in a car or on a train.
When you're stationary, (low-mobility local wireless access) it decided that 4G should be able to deliver speeds up to around 1Gbit/s.
If true 4G is supposed to offer us download speeds of up to 1Gbit/s, then why are we getting 100x less in the UK, at around 10-12Mbit/s in real-world speeds?
Unfortunately the ITU-R doesn’t have control over the implementation of the standard, which led to first-generation technologies like LTE being criticised for not being up to scratch with true 4G. (We'll explain LTE in a minute.)
The reason for this is that other groups (3GPP being an example) that work with the technology companies who develop the hardware had already decided upon next-gen technologies, leaving us with sub-standard 4G capabilities.
What is LTE?
Though originally marketed as 4G technology, LTE (Long Term Evolution) didn't satisfy the technical requirements that the ITU-R outlined, meaning that many early tariffs sold as 4G weren't actually 4G.
However due to marketing pressures and the significant advancements that LTE brings to original 3G technologies, the ITU later decided that LTE could be called 4G technology.
So, LTE is a first-generation 4G technology that should theoretically reach speeds of around 100Mbit/s. Unfortunately, Ofcom reports that the UK average is around 15.1Mbit/s. While that's around twice the speed of an average 3G connection, it’s a long way off from the theoretical top speed of LTE.
As well as lacking in overall download speed, LTE also lacks uplink spectral efficiency and speed. Uplink spectral efficiency refers to the efficiency of the rate that data is uploaded and transmitted from your smartphone.
It falls short of the true 4G capacity mainly because of the lack of carrier aggregation (explained below) and because phones don't have enough antennae.
That's where MIMO (Multiple Input Multiple Output) comes in. It's a practical technique for sending and receiving more than one data signal on the same channel at the same time by using more than one antenna.
With better carrier aggregation and MIMO, we can head towards a new standard: LTE Advanced. This is also known as 'true' 4G.
Imagine playing a PlayStation 3 when you could be playing a PlayStation 4. The PS3 isn’t necessarily too slow to use, but you’d have a better experience using the faster console, the PS4. It’s the same with LTE – LTE is the PlayStation 3 and LTE Advanced (LTE-A) is the PlayStation 4.
What is carrier aggregation?
Carrier aggregation is part of LTE-Advanced and lets operators treat multiple radio channels in different or the same frequency bands as if they were one, producing quicker speeds and enabling users to be able to perform bandwidth hogging activities like streaming HD video much faster than ever before.
Think of your wireless connection as a pipe. You can't increase the size of the pipe, but you can add a second and third pipe. Use all three simultaneously and you’ll have three times the flow rate. It’s the same concept with carrier aggregation.
Another advantage of carrier aggregation is that speeds don’t decrease, no matter how far away from the cell tower you are.
Combining two signals - or channels - should theoretically double the download speed to around 150Mbit/s. In the future, there could be aggregation across more than two channels, potentially up to five, which was defined in the LTE Advanced standard.
What about HSPA+?
HSPA+ may be marketed as 4G technology but it’s technically 3G. HSPA+ stands for High Speed Packet Access Plus. It was the next step after 3G, with UK network provider Three aiming for it to be used by 2012 (before the introduction of LTE).
The technology was developed with a theoretical top speed of 21Mb/s, which is pretty impressive for technology that doesn’t count as 4G (3G has an average speed of around 1Mb/s). However, it was quite a way away from its theoretical top speed as the average is around 4Mb/s.
Who offers the fastest 4G LTE connection?
Now you know more about what the difference is between true 4G and the 4G LTE we’re being sold, which UK network provides the best 4G LTE connection? In November 2014, Ofcom tested the 3G and 4G connections of every major provider in the UK in five cities.
The results proved that EE has the fastest 4G LTE connection, measuring in at 18.4Mb/s on average, though still far from the theoretical top speed of LTE. You can see the results in the graph below:
Research and graph by Ofcom
It’s not just the download speed that dictates overall responsiveness of a 4G connection; latency also plays an important part. A lower latency provides better responsiveness and reduced delays when using data for browsing, video calling, etc.
Surprisingly, EE wasn’t the best provider when it came to latency – that award went to Three. Ofcom reports that Three took the least time to deliver data on both 4G (47.6ms) and 3G (53.8 ms), while O2 came last with the highest levels of latency, measuring in at 62.7ms on 4G and 86.4ms on 3G.
LTE-A is already available in selected areas – Vodafone started its LTE-A rollout in Birmingham, Manchester, and London, while EE offers it in most major UK cities.
Upgrading infrastructure to support LTE-A will be a slow process and is likely to take a couple of years, much like the initial 4G rollout. You won’t automatically get LTE-A though: there are other factors that have to be taken into consideration.
The main one is compatibility. Your phone be need to support LTE-A. As with the 3G to 4G migration, many existing phones don’t have the technology to be compatible with LTE-A. The good news though is that most recent devices, especially flagships, support the tech including:
- iPhone 6s onwards
- iPad Pro
- Blackberry Priv and Passport
- Google Pixel and Pixel XL
- HTC One M9, A9, and 10
- Moto Z and X Style
- LG G3 onwards
- Huawei Honor 6, Mate 8, and P9 onwards
- OnePlus 2 onwards
- Samsung Galaxy S5 onwards, Notes S4 onwards, and A-series
- Sony Xperia X, XZ, and Z3 onwards
The good news is that it appears that both Vodafone and EE aren’t charging people for the extra speed. As long as you’re in a supported area and using a compatible phone, you should be able to enjoy the benefits of LTE-A’s carrier aggregation and see (theoretical) download speeds of around 150Mbit/s. Just watch out you don't burn through your monthly data allowance in a few minutes!
4G LTE Advanced - What you need to know about LTE-A
What is 4G LTE Advanced?
The various UK networks are still scrabbling to expand their 4G LTE coverage but already we're seeing 4G LTE-A or LTE-Advanced in some areas, which is essentially a far faster version of the already speedy 4G. Read on for the low down on just how fast it is, how it works and when you can get your hands on it.
Just how fast is it?
There’s no hard and fast answer as to how speedy LTE-A is. Theoretical peak download speeds stand at around 300Mbps whilst standard 4G LTE stands at 150Mbps.
Having said that you’ll likely find that the real world download speeds of 4G normally top out at around 15Mbps, as other factors such as the device you’re using it on, your proximity to a 4G mast and how many other people are on the network all drastically affect the speeds.
Similarly you’re not likely to get consistent LTE-A speeds of 300Mbps, but it’s still likely to deliver consistent real world speeds of over 42Mbps and up to 90Mbps, making it at least 3 times faster than standard 4G LTE speeds.
How does it work?
Essentially while standard data connections use one antenna and one signal at any given time, 4G LTE-A uses multiple signals and multiples antennas.
It uses MIMO (Multiple Input Multiple Output) technology to combine multiple antennas on both the transmitter (for example 4G masts) and the receiver (for example a smartphone). So a 2x2 MIMO configuration would mean there were two antennas on the transmitter and two on the receiver and you don’t have to stop at two, the more antennas theoretically the faster the potential speeds as the data streams can travel more efficiently.
That technology is then combined with ‘carrier aggregation’, which allows a device, such as a smartphone, to receive multiple different 4G signals at once and they don’t even have to be on the same frequency, so you could receive an 1800MHz and an 800MHz signal at the same time for example, none of which is possible with standard 4G.
Up to five different signals can be combined at once and with each offering up to 20MHz of bandwidth they can be combined to create a data pipe of up to 100MHz of bandwidth.
The upshot of all that is that it’s faster than standard 4G, a lot faster.
When can I get it?
EE already offers LTE-A, marketed as 4G+. However it's only available in a handful of places so far. Most of greater London can benefit and that's the only area you'll really find consistent coverage, but there's some coverage in the likes of Birmingham, Manchester, Liverpool and other major cities. While EE hasn't confirmed its future plans for the service we'd expect it will make a big push in expanding its coverage throughout 2016, so watch this space.
The only other UK network with any LTE-A availability if Vodafone, which currently offers it in London, Birmingham and Manchester.
The other networks are further behind. The German branch of O2 has tested LTE-A in a lab setting, but nothing has yet been done on these shores and there’s no word yet on when the network will roll it out commercially. For now they’re likely focused on expanding their standard 4G coverage so we’d be surprised if we saw any availability from them before mid 2016.
Three’s LTE-A ambitions are even less known and as the network was the last to launch 4G there’s every chance that it will be the last to launch LTE-A as well, so don’t hold your breath for seeing it any time soon.
But it is coming and we fully expect all the networks to offer it eventually. With EE and Vodafone already offering it in a limited capacity that’s likely to put pressure on the competition.
What phones work with it?
Not only might you have to wait a while to get LTE-A if you're not on EE or Vodafone or not in a major city, but you might have to get a new phone. Standard 4G phones don’t support it and no handsets currently available in the UK are LTE-A ready, which is fair enough really, since no networks offer it.
Many newer handsets, particularly high-end ones, such as the iPhone 6S, Samsung Galaxy S6, Sony Xperia Z5, HTC One M9, LG G4 and Microsoft Lumia 950 support it, but most older and lower end handsets don't. The good news is that over time more and more smartphones will arrive with LTE-A support and as it becomes more widespread it should start filtering down to low end devices too.
LTE-A not fast enough for you? Well this is a fast moving industry and people are always looking ahead. So much so that 5G is already in development. The term ‘5G’ literally just means that it’s the fifth generation of mobile wireless systems and you can expect it to be a big jump.
The specifics are still being worked out and it’s unlikely to be commercially deployed before 2020, but talk at the moment is that it will theoretically allow for data speeds of up to 10Gbps, which is just a mind boggling number.
What's all this about 4G LTE-Advanced? I need to get up to speed with 4G-LTE first.
