AT&T 5G: Everything you need to know

AT&T's 5G network is still a work in progress, but with more than 250 million people covered, the steady expansion of mmWave and C-band spectrum, and a fast LTE network as a backup, AT&T is set to make a 5G comeback in the next couple of years. AT&T's 5G network is made up of three primary parts. There is a nationwide network comprised of low-band and shared spectrum, mid-band spectrum including C-band, and mmWave for dense areas.

These pieces come together to form one of the most competent mobile networks around, especially if you live in a rural area. While its 5G expansion hasn't quite kept pace with T-Mobile and Verizon, the carrier is hard at work expanding its network coverage and performance. 

How is coverage improving?

AT&T's 5G network is comprised of three main parts. The first part is a low-band 5G deployment at 850MHz and uses some Dynamic Spectrum Sharing with speeds similar to LTE. The second piece is a mid-band 5G made up of mid-band spectrum around 3.7GHz, similar to Verizon's C-band network. The final piece is a high-band mmWave network capable of very fast speeds and high capacity but with a more limited range.

Dynamic Spectrum Sharing, or DSS, is a technique that reuses some of the spectrum currently used for 4G with both 4G and 5G as the need grows. Unlike the refarming spectrum from LTE and simply moving capacity from one network to the other, DSS can keep both networks active and allocate portions of that spectrum as needed to either 4G or 5G. This allows the network to adjust to higher 5G demand as people upgrade their phones.

While the majority of AT&T's 5G coverage is still made up of this slower network, the carrier has been making solid mid-band progress and even achieved its goal of 70 million covered by the end of the year, much earlier than expected, and estimates coverage of 100 million by the end of 2022. Those in urban and suburban areas will see mid-band coverage sooner than rural customers since the higher frequencies don't reach as far as low-band frequencies.

One thing to keep in mind is that not all 5G is what it seems. AT&T began preparing its towers for a 5G network with LTE upgrades it calls 5GE. This essentially added the network capacity on the backend for 5G, including upgraded fiber network connections. If you see 5GE on your older AT&T phone, this is not 5G and is actually 4G LTE with tower upgrades that make the most of LTE technology.

AT&T's mmWave coverage

For the most part, you'll be using the larger low-band 5G coverage through 2022 as AT&T builds out the places where it has access to the mid-band spectrum. However, if you have one of the phones that supports AT&T's mmWave 5G+ network, you can still get some incredible speeds in several U.S. cities.

These markets now have AT&T 5G+ coverage.

Arenas and Venues

AT&T has also continued to focus on bringing mmWave 5G to stadiums and venues across the country. These buildings are the perfect demonstration of mmWave's strengths with large numbers of people in an open area that can be easily covered by 5G. This is also helped by the large number of people that wish to capture and share pictures and videos from the events they attend.

Which phones work with 5G?

Most of the new phones AT&T sells work with 5G, including many of the best Android phones like the Galaxy S22 series and Pixel 6. Apple's 5G iPhones are also supported. If you're looking to update your AT&T phone, it's the right time to ensure it has 5G built-in.

The Features & Specs table on AT&T's website lists each phone's 5G support. Mid-band and mmWave 5G will be listed under the 5G+ category, with band n260 for mmWave and n77 for mid-band. Nationwide 5G will include the bands n2, n5, n30, and n66, although coverage will mainly depend on what's available in your area.

Having a phone that at least supports mid-band n77 is important if you care about getting the most from the network, as the majority of significant 5G expansion will be coming from the mid-band in the next few years.

Which plan do I need?

All of AT&T's current unlimited plans include 5G access. If you want to go for a data plan such as the 4GB plan, you won't get any access to 5G at all. Like most of the best 5G plans, AT&T treats its low-band nationwide 5G data the same as LTE regarding hotspot and premium data.

Currently available AT&T plans with 5G access include AT&T Unlimited Elite, AT&T Unlimited Extra, AT&T Unlimited Starter, and AT&T Value Plus. Keep in mind that only Unlimited Elite and Extra include priority data, so the other may experience slower speeds when the network is congested.

AT&T has added 5G support to several of its older unlimited plans. This is great for people who want to upgrade to a 5G phone and use the growing network but don't want to lose a current promotion or go through the hassle of changing a plan. This applies to consumer and business unlimited accounts alike.

These AT&T plans will now get access to 5G service with a 5G compatible phone.

With AT&T Prepaid, you can only get 5G with the most expensive Unlimited plan which comes in at $50 per month with auto-pay.

Cricket, the AT&T-owned prepaid carrier, now offers 5G access on all its plans. Combined with the recent removal of speed limits from Cricket's plans, this carrier is a great way to test out AT&T's 5G network.

What tech is AT&T using for 5G?

AT&T first started its 5G network with mmWave tech. This uses a high-frequency spectrum above 24GHz for coverage, and this spectrum is available in large chunks allowing for enormous speeds of over 2Gbps in ideal conditions. With a solid signal, mmWave can handle a large amount of traffic while staying fast enough to get just about anything done on your phone.

AT&T next launched a low-band sub-6 5G network at 850MHz. This is the network that most customers will be able to connect to since it has much better coverage than mmWave. The coverage areas from a single tower will be much more like LTE, but so will speeds. This low-band 5G will essentially fill in the gaps where deploying a denser coverage is not practical. AT&T is also sharing some spectrum with LTE where possible to balance the network for the current load.

Lastly, AT&T started deploying C-band spectrum in late January 2022. While its initial footprint was small, with just eight cities at launch, AT&T has continued to expand and improve. The carrier reached 70 million, covered two quarters ahead of predictions, and a new target of 100 million by the end of 2022. AT&T has also acquired a significant amount of mid-band spectrum in the so-called Andromeda Auction.

Is 5G worth it for most people?

In ideal conditions, 4G LTE is fast enough for most people. However, one problem is that these good speeds lead to data usage constantly increasing as media quality improves and download sizes grow. As a result, there will be a hard ceiling on the amount of data one tower can deliver with LTE technology, and the user experience will start to suffer.

All of AT&T's Unlimited plans now include 5G access, so if you're ready for a new phone, there's a good chance it will come with 5G.
