Over 50% of the world’s LTE subscribers are in the US right now. With aggressive 4G deployments aided by the thriving application ecosystem, US wrestled back the leadership mantle of the mobile world. While consumers are enjoying their mobile broadband devices and services, chatter around 5G has begun. Some new to the industry might be perplexed by all the talk of a technology cycle that is years away. However, if we study the 35 year old history of the mobile industry, things are going according to the plan.
All the major mobile markets have started to focus on defining 5G and the subsequent launch dates. Even Europe, which still has a long way to go before their 4G networks are built out have set their sights on 5G to recapture the mantle and the pride of the GSM days. Korea and Japan led the world in 3G but lost the lead of 4G to the US. They both are eager to be considered leaders in 5G. Japanese government has set the ambitious goal of having 5G by the Tokyo Olympics in 2020 (Russia wants to do it by 2018 for the FIFA World cup). US regulators have also started to talk about 5G and the future spectrum needs as well.
