5G is here, Verizon has installed "hundreds": of mmWave cells, per CEO Lowell McAdam. Korea Telecom is building rapidly a system along Highway 50, ready to astound the world at the Olympics in February. Massive MIMO is expanding rapidly. Softbank in Japan and China Mobile are installing thousands of towers, Bharti in India has now joined. Sprint in the U.S., Vodafone, and Deutsche Telekom are building and will soon have major announcements. I predict huge growth in M MIMO in 2018 & 2019.
These are not tests. Nor are they "trials," of which there are hundreds. Countries only go on these maps when I'm confident they are building and ready to serve customers. Updates and improvements very welcome.
