First 28GHz mm-wave 5G transceiver demoed in US

National Instruments says it has given the world’s first public demonstration of a real-time, over-the-air prototype for Verizon 5G specification operating in the 28GHz frequency band which is likely to be deployed for first 5G services in the US.

A prototype system was built using NI’s mmWave transceiver system with a new version of the RF mmWave heads operating at 28GHz and phased array antennas developed by Anokiwave and Ball Aerospace.

The system, which was demonstrated at the IEEE Wireless Communications and Networking Conference (WCNC), uses OFDM with eight component carriers in a 2×2 downlink MU-MIMO configuration with hybrid beamforming and a self-contained subframe, yielding a 5Gbit/s peak throughput, and is scalable to over 20 Gbit/s with eight MIMO streams.

James Kimery, director of RF research and SDR marketing at NI, writes:

“Researchers can take advantage of the combination of hardware and software to rapidly prototype new wireless standards and iterate quickly to reduce time to results. They can now prototype and test the Verizon 5G specification and move immediately to 5G New Radio once the standard stabilises.”

US mobile operator, Verizon announced the availability of its 5G Technology Forum specification in 2015.
