Verizon and Nokia this week touted the industry’s first successful outdoor test of a 5G connection using 3GPP standards.

The tests, which were conducted at Verizon’s campus in New Jersey, also used multi-carrier aggregation to reach throughput speeds of up to 1.8 Gbps, officials said.

“By continuing to push the technological envelope and make advancements like these, we’re driving the ongoing development of 5G technology and bringing it to life for our customers,” Verizon 5G Ecosystems & Innovation VP Sanyogita Shamsunder said in a statement.

The carrier and telecom equipment maker collaborated to transmit multiple live virtual reality sessions, as well as simultaneous 4K streaming video, on 28 GHz spectrum with latencies of 1.5 milliseconds.

Verizon, Nokia and Qualcomm completed a 3GPP standard-compliant 5G connection in a lab setting earlier this year, but officials said the outdoor tests more closely mirror how businesses and consumers will use 5G.

“Our successful trial pushes the testing distance and because it has been conducted outside, tests the interference variables in an outdoor environment,” said Nokia Mobile Networks President Marc Rouanne. “This is a major milestone for preparing Verizon for widespread 5G implementation.”

Verizon plans to launch 5G fixed wireless service in four U.S. cities by the end of the year.
