Keysight Technologies and the University of California, San Diego (UCSD) have announced the world's longest bidirectional phased-array link in the 60GHz band.
The 32-element array sent data at a rate higher than 2 Gbps all over scan angles up to 45 degrees at a link distance of 300 meters. Data rates were 4 Gbps at 100 meters and 500 Mbps at 800 meters over most scan angles, and initial tests suggest the system can deliver content to eight homes simultaneously at a maximum of 300 meters.
UCSD researchers employed Keysight's Signal Studio software to define and produce the 60GHz 802.11ad waveform, which was the developmental platform. Using UCSD's high-performance system-on-a-chip designs, the phased array only consumed 3 to 4 watts of direct current power in either its transmit or receive modes.
"This is the second time UC San Diego has worked with Keysight to demonstrate high-performing phased-array 5G communication links, now achieving gigabit-per-second speeds at previously unimagined ranges and with extremely low power consumption," says Gabriel M. Rebeiz, wireless communications industry chair at UCSD's Jacobs School of Engineering.
