Test and Measurement: Aviat tests 6 GHz unlicensed devices for microwave-link interference

August 14, 2020


Microwave network equipment company Aviat Networks this week announced results of field tests conducted with Ameren and the Electric Power Research Institute (EPRI), focused on exploring the effects of unlicensed device use at 6 GHz on microwave point-to-point links in the band.

Aviat said that the testing was conducted on one of its existing links, an 18.5-mile Aviat IRU 600v3 microwave link in Ameren’s network that operates at 5974.85 MHz with a 30-megahertz channel and 256 QAM modulation configuration, with 8-foot antennas. The companies tested two types of unlicensed devices, both of which “were found to produce interference to the incumbent microwave link when operating in a co-channel frequency,” Aviat said.
