U.S. telco uses mmWave spectrum to underpin next-gen network experience at Intel office.

AT&T this week claimed a world first with the launch of a 5G trial with a business customer.

The U.S. telco and hardware supplier Ericsson created a 5G network experience at one of chip giant Intel’s offices in Austin, Texas, based on millimetre-wave (mmWave) spectrum.

"We’re leaving the lab and heading into the field with a real-world business customer," said Rick Hubbard, SVP of networking product management at AT&T, in a statement on Tuesday.

With a mobile network capable of reaching 1 Gbps in place, the companies then tested several enterprise use cases, including VPN, unified communications and 4K video streaming.

"The trial will help accelerate our 5G work by shedding new light on how the technology acts in a business environment," Hubbard said.

AT&T said the trial will also showcase the potential of 5G VoIP using 15-GHz and 28-GHz spectrum.

"Intel is committed to collaborating with industry leaders to develop leading technologies and solutions that expedite network readiness for the successful early rollout of 5G," said Aicha Evans, general manager of Intel’s communications and devices group.

"We are excited to work with AT&T on this initial trial as we work to deliver the products and investments that will bring 5G to life," she said.
