AT&T Adds Nokia to 5G List, Expands Tests

AT&T is adding Nokia to its list of 5G test vendors, expanding trials into new cities and claiming speeds of over 10 Gbit/s in initial trials with Ericsson.

AT&T Inc. (NYSE: T)'s initial focus has largely been on setting up tests at its labs -- and around the city. The operator now says that it has begun system and software architecture lab work in Middletown, N.J., Atlanta, Ga. and San Ramon, Calif. (See AT&T's Wolter: 5G Isn't Just Bigger, Better, Faster.)

AT&T has already filed for a license to perform 5G tests at 28GHz and 39GHz in New Jersey. It hasn't said if Nokia Networks will be part of those trials, but the vendor will be working with Ma Bell on millimeter wave tests. (See AT&T Will Do More 5G Tests in N.J.)

"We've seen great results in our 5G lab trials, including reaching speeds above 10 gigabits per second in early tests with Ericsson," said Tom Keathley, SVP of wireless network architecture and design at AT&T, in a statement. "Nokia is joining to help us test millimeter wave (mmWave), which we expect to play a key role in 5G development and deployment."

AT&T has previously revealed that it is working with Ericsson AB (Nasdaq: ERIC) on pre-standard 5G network gear and Intel Corp. (Nasdaq: INTC) on devices. (See AT&T 5G Trials to Start With Fixed 15GHz Tests.)

All of the big four US carriers have now started testing, or committed to test, pre-specification 5G mmWave equipment. Sprint Corp. (NYSE: S) is the latest, kicking off 5G tests in sports stadiums last week. (See Sprint Kicks Off 5G Tests in Levi's Stadium.)
