Major wireless carriers have been building out their 5G networks in test cities, reﬁning the details and use cases before wider rollouts. This isn’t a quick, easy effort. In fact, an article in the New York Times stated, “The shift to 5G feels like a tech revolution happening in slow motion.” Although AT&T and Verizon plan to have their 5G networks available nationwide in the US in 2020, devices and applications will still take a while to catch up. To provide an idea of the pace of the rollout, Cisco estimates that by 2022, 12% of all mobile trafﬁc will be on 5G and that 422 million mobile devices will be 5G-capable.
Once fully implemented, the capabilities 5G offers – high speed, more bandwidth, ultra low-latency – promises to fundamentally alter the mobile landscape.
