AT&T Plots Mobile 5G Tests in 2017

AT&T is now expecting to start mobile 5G tests in 2017.

Scott Mair, SVP of technology planning and engineering for AT&T Inc. (NYSE: T), speaking at the Jefferies 2016 Technology Conference last week, reiterated that the operator is planning 15GHz fixed wireless tests in Austin, Texas, this summer. This will be followed at the end of 2016 by 28GHz fixed 5G tests. (See AT&T 5G Trials to Start With Fixed 15GHz Tests and AT&T Will Do More 5G Tests in N.J.)

"In early '17 we'll be rotating into that mobility use case," Mair said. "We expect that we'll be doing some field deployment ... with pre-standards equipment by late '17."

Major rival Verizon Communications Inc. (NYSE: VZ) is working on at least eight 5G test sites in the US. Big Red is planning a fixed 5G pilot sometime in 2017. (See Verizon Hits 1-Gig+ in 5G Trials, Eyes Early Applications and Verizon Will Pilot 5G Fixed Wireless in 2017.)

"We haven't been sitting still on 5G, we've been doing a lot of work in the labs ourselves," Mair says.

AT&T's early testing will be in the high-frequency centimeter wave frequencies -- 15GHz and 28GHz. The operator has so far said it is working with Ericsson AB (Nasdaq: ERIC) on the 5G network side and Intel Corp. (Nasdaq: INTC) for devices. (See AT&T Wants to Start 5G Tests in Austin and Intel Wants to Be a 5G Player.)

Mair expects AT&T to get more catholic, however, with its radio band choices as 5G evolves. "We'll use millimeter wave but we'll also use other spectrum bands, the bands deployed today," Mair said. "As well there's the 3.5GHz that's coming. That's more WiFi-based ... it's possible we'll use all those bands."

"Initially, it's gonna be dense urban core, some suburban deployments," Mair said of future 5G millimeter deployments.

Standards-wise, Mair is expecting the Phase 1 5G standards to arrive in September 2018, with fixed and enhanced broadband wireless "use cases."

"The other two use cases that we see will come about a year later, in late '19," Mair said. These are "massive IoT," which anticipates a million networked machine-to-machine devices being deployed in an area less than a mile square. The other use case leans on less-than-a-millisecond latency connection time expected in 5G networks to start to actually make smart cities, medical devices -- and more -- a reality.

"Typically what we see from a commercial production or deployment standpoint is that it is about a year from [when] the standards come out," said Mair.

Which still puts commercial 5G deployments happening in or around 2020.

Mobile test terminals Wonder how big the mobile test terminals will be by 2017?

Re: Mobile test terminals Wonder how much ATT will pay for Straight Path's "STRP" nationwide spectrum?

Re: Mobile test terminals Mair didn't mention 39GHz though, only 28GHz. Straight Path's LMDS licenses are all in the North-East, no?

Re: Mobile test terminals It will be interesting to watch the competition as test move forward. With Verizon "working on at least eight 5G test sites in the US," you can be sure everyone is going to be watching AT&T closely.

5G Well it nice that AT&T will be testing in 2017.  However, I could be mistaken, but Sprint has their 5G test in about 7 days!  Shouldn't we be talking about that?

"Wonder how big the mobile test terminals will be by 2017?"

Samsung 5G : A custom made Galaxy phone.

Nokia and Ericsson 5G : A portable suitcase.

AT&T agrees Samsung 5G will be ready for demonstration in Februrary of 2018.


AT&T's Wolter isn't expecting smaller commercial 5G devices to arrive until 2020. "We understand that there may be some things that may be ready for the Olympics in Korea [2018], but they'll really be one-offs," he said.

Re: Mobile test terminals Yes, that's why I linked to the SKT milestone story. They still have work to do though, the Galaxy was rocking a 60GHz module at MWC.

Re: 5G It will be a bit confusing I'd say as some get into testing before AT&T while most seem to be moving forward even before the standards are set in 2018 or so. Getting to " "massive IoT," which anticipates a million networked machine-to-machine devices being deployed in an area less than a mile square" successfully will be very interesting to watch while on the other hand some other devices will require very low latency but not be so closely spaced.
