It often is said that 5G builds on 4G, and that is correct. Consider AT&T, which is boosting 4G speeds as it launches 5G markets. AT&T plans to bring mobile 5G to 12 cities in 2018, reaching at least 19 cities in early 2019.
AT&T also has announced 99 new 5G Evolution markets, bringing the total number of such markets with these technologies to 239. 5G Evolution markets are locations where peak theoretical wireless speeds for capable devices are at least 400 megabits per second.
AT&T says 5G Evolution will be available in over 400 markets by the end of 2018. In the first half of 2019 AT&T plans to offer nationwide coverage, making 5G Evolution available to over 200 million people.
The other technology AT&T is deploying is LTE-LAA, which boosts peak theoretical wireless speed for capable devices to a gigabit per second. LTE-LAA is now live in parts of 20 cities with plans to reach at least 24 cities in 2018.
In terms of devices, AT&T offers 13 devices capable of accessing both 5G Evolution and LTE-LAA network technologies. The devices include: LG V30 and LG V35 ThinQ, Motorola Z2 Force Edition, Netgear Nighthawk Mobile Router, Samsung Galaxy S8 and Galaxy S9 series devices and others.
