Vehicle-based 5G NR call mobility testing is a first, Verizon says

Verizon and Nokia have successfully tested a 5G New Radio call in a vehicle moving between two sectors, the two companies said. Verizon described the testing as “the first successful transmission of a 3GPP New Radio 5G signal to a receiver situated in a moving vehicle, seamlessly handing off the signal from one radio sector to another.”

The testing was conducted in Murray Hill, New Jersey, at Nokia’s campus. Verizon noted that the two companies have worked together over the summer on other testing, including a series of 5G NR outdoor data sessions and multi-carrier aggregation.

Verizon said that the call mobility test involved a data transmission at 28 GHz that was sent from two 5G NR radios on Nokia’s building, to a vehicle that had a receiver and test equipment to measure transmission information.

“The vehicle traveled between the two radios, achieving seamless 5G NR Layer 3 3GPP-compliant mobility handoff of the signal between the two sectors,” Verizon said, noting that these were intra-gNodeB and inter-distributed unit handovers.

“Unlike some of the incremental 5G technology announcements we’ve seen lately, tests like the one we conducted are significant advancements in the development of 5G technology,” said Bill Stone, Verizon VP for technology development and planning, in a statement. “By taking these tests out of the lab and into the field, we’re replicating the experience users will ultimately have in a 5G mobility environment.”

“We are pleased to showcase the acceleration of the mobile capabilities in 5G,” said Marc Rouanne, Nokia’s president of mobile networks, in a statement. “Enhanced mobile broadband is one of the first services being delivered on Nokia’s end-to-end 5G Future X portfolio. As a result, we can help our customers meet their early 5G deployment schedules and initial coverage demands.”
