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. 

Verizon Ready to Try Massive MIMO and Beamforming

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

Nokia's Moliin: Massive MIMO/Interference Cancellation is Ready

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.

Go WestSuddenly 2017 rather than 2020 looks possible for Massive MIMO and beamforming. Verizon told Wall Street they were close to trials. Nokia next quarter will test Antonio Forenza's pCells, with similar features. Verizon's Lowell McAdam also briefed the street on a plan for "Staying ~two years ahead of competitors in network performance." (Paul de Sa.) They can't reach that goal without pulling up technologies that most thought were five years away.  

"Go Massive" is the conclusion of Robert Heath, at The University of Texas at Austin.

massive mimo linkopingsHoping for 2017 although almost no one expected this before 2020 and "5G." CEO Lowell McAdams told analysts Verizon plans  "Staying ~two years ahead of competitors in network performance."  Massive MIMO and beamforming deliver "Huge gains in spectral efficiency." Delivered wireless can increase two to ten times over the next few years using arrays of thirty-five to hundreds of antennas. A 10x jump wouldn't surprise any of the researchers. Pulling that far ahead is probably an impossible dream. AT&T has almost caught up with Verizon. 

Until this week, almost everyone thought substantial Massive MIMO deployment unlikely until 2020 and 5G. The excellent Bernstein analyst Paul de Sa was the first to report "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)." I confirmed with a second analyst what was said.

Beginning trials soon would suggest deployment in 2017 if they go well.

Marzetta Massive10x or 100x more wireless throughput using many antennas. Masayoshi Son at Softbank has just deployed the first commercial Massive MIMO systems. 100 systems, each with 128 antennas, are being deployed in Japan. The early results show 6-10X capacity improvements. Some of the world's best engineers - Henry Samueli, Andrea Goldsmith, Arogyaswami Paulraj, Vint Cerf - expect ultimately MIMO will yield a 50X improvement. (That's not guaranteed, of course.)

Ericsson announced they'd be shipping 64 antenna systems in 2017. Huawei, ZTE, and Facebook have demonstrated 96-128 antenna systems. Each transmitting antenna sends a separate signal. The receivers mostly have two or four antennas. Each signal bounces off walls and other obstacles in a slightly different way, allowing the receivers to separate them. 

Paulraj invented MIMO in 1993 and nearly twenty years ago predicted a 100X improvement in capacity at very little power increase. Many of us have seen a preview of what's possible from WiFi 802.11ac. That uses 4 antennas and triples performance under the right conditions. Add more antennas and enough processing power and almost anything may be achievable.

ArtemisVerizon and Nokia are ready to test. Nokia CTO Hossein Moiin intends to test Antonio Forenza's pCell technology early next year. Last year, I wrote extremely skeptically about Artemis/pCell informed by three very respected engineers. CEO Steve Perlman made wildly implausible claims, including that they would deploy across 350 San Francisco rooftops by the end of last year. They haven't been seen.

Moiin is a respected, independent engineer. I have to look again. USC Prof Giuseppe Caire now says "The early trials showed pCell achieving far higher concurrent user capacity than any wireless technology I am aware of." That's very different from his earlier comments (below) and I assume he's been shown something newer. Peter White at Faultline has an important article about semi-secret trials in U.S. sports stadiums. (Paywall.) 

Verizon in a startling move Monday told analysts they would soon test Massive MIMO and beamforming. (pCell is very similar.) These are key "5G" tools that weren't expected until about 2020.

zte pre5GChina Mobile, ZTE & Huawei are seeking to lead the 5G/4G future. MIMO work was initially led by U.S. researchers. Stanford's Paulraj won the Marconi Prize for inventing it. Gerry Foschini and Tom Marzetta of Bell Labs did crucial work. Most of the first thousand papers came from the U.S. and Western Europe. Lucent was the world leader in most areas of telecom. The U.S. telcos had massive research centers.

Today, those three remain active and others like Ted Rappaport, Andrea Goldsmith and Robert Heath are prominent at important universities. But the industry has changed. Huawei is now the world's largest telecom company and has committed $600M to 5G research. ZTE is now in the top five. The EU has promised a billion for 5G research, much of which will come to market through Ericsson and Nokia.

The Site for Massive 230
dave ask

Massive MIMO is rapidly deploying across the world; Soon, I'll be adding many more countries to the Massive MIMO map. On average, adding 64 or 128 antennas triples the performance of the cell site at moderate cost. Ericsson, Huawei, and ZTE are shipping by the thousands.

Being a reporter is a great job for a geek. I'm not an engineer but I've learned from some of the best, including the primary inventors of DSL, cable modems, MIMO, Massive MIMO, and now 5G mmWave. Since 1999, I've done my best to get closer to the truth about broadband.
