Many of the best coming April 8-10 for Ted Rappaport's Brooklyn 5G Summit. 5GW News was conceived at last year's event. AT&T's #2 John Stankey, the CTO of NTT DOCOMO Seizo Onoe, and many of their peers spoke at the 2014 first event. I was then a doubter but these guys are serious. Folks at that level wouldn't have flown from around the world unless 5G was closer than i thought,
In 2015, everyone's rushing to promise 5G despite no one knowing just what it will be. 5G performance will be 10-100 times faster than today's wireless. The three most important technologies are Massive MIMO & MU MIMO; millimeter wave high frequency cells; and bottoms-up small cells, especially WiFi from everyone's home gateway.
I've pasted in the speaker list below. It's a veritable who's who of 5G research.
1) High frequencies have enough spectrum available to easily deliver gigabits.
