Verizon and Nokia refuse to wait for 2020 for 5G. Massive MIMO promises major speed jumps in the same spectrum. Testing in 2016 for Massive MIMO, beamforming and interference cancellation. Hopes for huge speed boost starting in 2017. Think 64 antennas and 5-10x throughput. Good engineers tell me it's possible but didn't expect it so soon.
Beginning trials soon would suggest deployment in 2017 if they go well. That's not guaranteed. Lowell McAdam plans "Staying ~two years ahead of competitors in network performance." They are getting ambitious, including going to Alcatel's TWDM PON for 40 gig. "VZ will soon begin market trials of 5G capabilities including 'massive MIMO' (which is when a large number of antennas are packed into a single device) and beam forming (which is when a wireless signal is concentrated on a specific location)."(Paul de Sa) Much more http://bit.ly/5G256Ant
CTO Hossein Moiin intends to test Antonio Forenza's pCell technology early next year. There have been stadium field trials that went well. Very big improvements are close in wireless. Four world-class engineers were comfortable with the forecast wireless capacity would soon increase 50 times or more.
USC Prof Giuseppe Caire today says "The early trials showed pCell achieving far higher concurrent user capacity than any wireless technology I am aware of." The 2015 demo showed 16 phones receiving 12.5 megabits from a 35 antenna hub. Last year, I wrote extremely skeptically about Artemis/pCell informed by three very respected engineers. That's impressive for 5 MHz. CTO Antonio Forenza's engineering work is in the mainstream of wireless research: MU/Massive MIMO, beamforming and interference cancellation. Much more, including the challenge of practical computation, much more http://bit.ly/pcellnok
Suddenly 2017 is possible, not 2020 & 5G."Go Massive" is the conclusion of Robert Heath. Delivered wireless performance can increase two to ten times over the next few years using arrays of thirty-five to hundreds of antennas. Tower, working with UCSD, has a 256 antenna transmitter that looks aimed at expensive military systems. Henry Samueli at Broadcom mentioned last year they were working on a chip for 50 antennas. much more bit.ly/gomassive
