In 2020, Apple released the first iPhones to support 5G connectivity, working with both mmWave and sub-6 GHz 5G. AT&T and Verizon both announced that their 5G service is available nationwide, with Verizon also indicating that its 5G Ultra Wideband service (up to 4 Gbps) is available in parts of 71 cities. T-Mobile, which acquired Sprint in April 2020, added 2,000 towns and cities to its 5G network with the launch of its independent architecture. This increased the total of cities covered to over 7,500.

But the more exciting aspects of 5G are yet to come, as the collection of technologies known as 5G become an integral part of the retail experience, fixed wireless access, manufacturing, healthcare, mobility — and woven throughout IoT.
