5G Coming Sooner, Not Later – IEEE Spectrum

Things are moving at blistering speed in the world of next-generation 5G mobile communications—even though many mobile users have still or only recently upgraded to 4G LTE communications, and even while 4G continues to evolve.

Nevertheless, four of the telecom industry’s big hitters—Japan’s NTT Docomo, South Korea’s KT and SK Telecom, and Verizon in the United States—are not waiting for stragglers to catch up.

Docomo, for one, has publicly committed itself to having 5G service up and running in time for the Tokyo Olympics in 2020.

As outlined by the International Telecommunications Union, 5G promises “a seamlessly connected society in the 2020 timeframe and beyond that brings together people along with things, data, applications, transport systems, and cities in a smart networked communications environment.”

To achieve all this, Docomo noted in a July 2014 White Paper, 5G would require data rates 100 times higher than today’s wireless networks offer, plus a reduction in latency to 1 millisecond, a 1,000-times increase in systems capacity, as well as a reduction in energy consumption.
