T Mobile LTE 230T-Mobile's main focus for 2018 was to be LTE-LAA, Mark McDiarmid, VP of network engineering told Monica Alleven at Fierce. In December, 2017, CTO Neville Ray promised they "will give customers even greater access to near gigabit speeds in 2018." They had just demonstrated speeds of 1.1 Gbps with Ericsson. (At end.) In February of 2018, T-Mobile proudly announced

Speeds of 1.3 Gbps were achieved by aggregating LTE carriers in licensed and unlicensed bands using five-component carrier aggregation, 256QAM, 4x4 MIMO and LAA on 14 antenna layers. 

Even without LAA, five-component carrier aggregation, 256QAM, 4x4 MIMO  is called "Gig LTE." Peak speeds can go up to 2 gigabits, but typical user seeds will be in hundreds. Update May 5: I'm sure people in Seattle are regretting their many comments about LTE, claiming results nearly the same as they expect from 5G NR in 600 MHz. Yet this Saturday, Tmo CTO Neville Ray tweeted about their LTE 

 @NevilleRay
Our network team added lowband LTE to 100s of sites in just two weeks, which means more and better coverage. And !!
You can expect another capacity upgrade announcement like this in a couple weeks.
But for D.C., he played loyal soldier.

The New would significantly enhance our network with immediate customer benefits like speed, coverage & capacity as we build a nationwide 5G network that puts the US in a 5G leadership position. Incredible potential! Key info below.

T-Mobile, Ericsson exceed 1 Gbps with LAA demo

 

The demonstration was performed in T-Mobile’s lab using Ericsson Radio System together with test gear from Cobham Wireless

T-Mobile (NASDAQ: TMUS) and Ericsson (NASDAQ: ERIC) have achieved speeds of 1.1 Gbps using 12-layer Licensed Assisted Access (LAA) technology – the first in the world to hit speeds beyond the 1 Gbps threshold on unlicensed spectrum. 

Neville Ray, Chief Technology Officer for T-Mobile, says: “T-Mobile has built the nation’s fastest LTE network by innovating and bringing new technologies to market for our customers. This LAA technology builds upon our deployments of 4x4 MIMO and 256 QAM and will give customers even greater access to near gigabit speeds in 2018.”

Fredrik Jejdling, Executive Vice President and Head of Networks at Ericsson, says: “Breaking the 1 Gbps-mark means that commercial gigabit speeds are not far from reality for many broadband users, with our LAA and MIMO technologies as key enablers. It is also an example of how innovatively we work with partners to push the boundaries of technology and achieve new milestones.”

The demo took place at T-Mobile's Bellevue, Washington lab using the Ericsson Radio System and test equipment from Cobham Wireless. The data speeds were achieved by combining several key LTE technologies including 256 QAM, 4x4 MIMO, and LAA by aggregating two licensed carriers and three unlicensed carriers.

The use of these LTE technologies on unlicensed spectrum complements licensed spectrum and makes it possible for a larger number of operators to reach gigabit speeds in their networks.
LAA has been demonstrated previously on 10 layers, reaching download speeds of up to 1 Gbps. Extending to 12 layers enables speeds exceeding 1 Gbps.

The Ericsson Radio 2205 gives operators the opportunity to deploy LTE on the 5GHz unlicensed band in outdoor micro cell environments. Using LAA, the unlicensed carriers on these radios can be aggregated with licensed carriers on the micro cells or on nearby macro cells.
 

dave askAugust 2018 Verizon's $20B 5G build is starting to add customers in 2018. Gigabit LTE & Massive MIMO became real in 2017 and enow expanding worldwide. Almost all the other "5G" is mid-band, 70%-90% slower + hype. Europe is mostly pr. The term 5G has been bastardized, unfortunately.

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.

Send questions and news to Dave Burstein, Editor. I always want to hear from you, especially if you catch a mistake.

 5G Why Verizon thinks differently and what to do about it is a new report I wrote for STL Partners and their clients.

STL Partners, a British consulting outfit I respect, commissioned me to ask why. That report is now out. If you're a client, download it here. If not, and corporate priced research is interesting to you, ask me to introduce you to one of the principals.

It was fascinating work because the answers aren't obvious. Lowell McAdam's company is spending $20B to cover 30M+ homes in the first stage. The progress in low & mid-band, both "4G" and "5G," has been remarkable. In most territories, millimeter wave will not be necessary to meet expected demand.

McAdam sees a little further. mmWave has 3-4X the capacity of low and mid-band. He sees an enormous marketing advantage: unlimited services, even less congestion, reputation as the best network. Verizon testing found mmWave rate/reach was twice what had been estimated. All prior cost estimates need revision.

My take: even if mmWave doesn't fit in your current budget, telcos should expand trials and training to be ready as things change. The new cost estimates may be low enough to change your mind.
