AUSTIN, Texas, Aug. 10, 2020 /PRNewswire/ -- Aviat Networks,
Inc. (NASDAQ: AVNW), today announced the results of recent field
testing with Ameren and Electric Power Research Institute (EPRI) to
determine the effects of unlicensed device interference on licensed
point to point microwave links in the 6GHz band.
The field test was conducted on an existing 18.5-mile Aviat IRU
600v3 microwave link in the Ameren network operating at 5974.85 MHz
with a 30 MHz channel and 256 QAM static modulation configuration
with 8-foot antennas. Two types of interferer signals were used; A
Part 15 compliant point to point radio and an IEEE 802.11ax
waveform from a signal generator. Several points were carefully
chosen both on and off the centerline of the main microwave beam to
a distance of 4.8km from the receiver. At the different points
several tests were conducted varying the interferer power levels,
the interferer bandwidth and applying partial fading to the main
link. At all times, the implementation of both the licensed
PTP link and the unlicensed 6GHz devices were within legal limits
of the FCC regulations.
Test Results Summary:
- Both types of unlicensed devices were found to produce
interference to the incumbent microwave link when operating in a
co-channel frequency. However, the two unlicensed sources did not
affect the link equally. The IEEE 802.11ax device produced less
interference compared to the Part 15 point to point radio
- The antenna elevation mismatch did not significantly protect
the incumbent licensed microwave link when the unlicensed sources
were at a distance <1.2 km
- Side and back lobes of the incumbent licensed microwave link
are vulnerable locations for a co-channel source of a Part 15
compliant transmitter
- Unlicensed sources operating at an adjacent channel frequency
did not cause any significant interference to the incumbent
licensed microwave radio
- Aviat's new Frequency Assurance Software (FAS) was successful
in detecting and reporting on the interference events and
accurately captured the interference details
"We are committed to providing the most reliable microwave
solutions at the lowest total cost of ownership," states
Pete Smith, President and CEO, Aviat
Networks. "This testing demonstrates that, with the evolution of
Wi-Fi 6e and other unlicensed devices operating in the band,
solutions like FAS which is an expert system to detect and report
on interference events, are critical to maintain the trusted
reliability of licensed microwave links."
