FAS Expert System Software

Integrated into ProVision Plus, FAS incorporates Aviat’s popular paperless chart recorder (PCR) application to simplify root cause analysis and isolate and analyze interference events with a single click of the mouse. FAS has an innovative algorithm that allows Aviat customers to baseline their networks before unlicensed 6 GHz rules go into effect so customers can see the effect of interference over time.

Benefits:

  1. Prevent outages – identify issues BEFORE they become real problems
  2. Protect yourself with data
    • Report on and trend your network over time
    • Isolate problem links, find the interferers and remediate issues
    • FAS lets you baseline your network to understand base case and impacts over time. Deploy now before unlicensed devices proliferate
  3. Manage your network from anywhere, anytime. With FAS you also get web-based management (for layer 1) and a management platform for the future (all new Aviat apps build on ProVision Plus)

Key features:

  • Interference analysis and alarms
  • Interference trends by network/link
  • Detailed and executive reports
  • Paperless Chart Recorder (PCR) integrated into FAS app for further analysis

Monitor 6 GHz RLAN unlicensed interference with Aviat's FAS software app

   

In addition to FAS, all new versions of Aviat radios, will come equipped with an integrated spectrum analyzer

Aviat's built-in spectrum analyzer gives you the power to confirm the presence of interference

Built-in and license-free diagnostic feature

Spectrum Analyzer feature is a built-in and license-free diagnostic feature to enable the user to check for potential interfering signals and measure the level of interference across the desired frequency range (limited by the diplexer bandwidth) and check the RSL (received signal level) of the interfering signal in 1.4 MHz steps.

IRU 600v4, ODU 600v2 and WTM 4000 all come with our built-in spectrum analyzer

While protecting the 6 GHz band is of utmost importance, it is not the only band or application being affected by interference. FAS has been designed to work on all bands from 6 GHz – 80 GHz and works on any Aviat radio including IRU 600, ODU 600, WTM 4000, and WTM 4800 with or without Eclipse or CTR 8000. Beyond 6 GHz, interference monitoring is important in countries with lax regulatory enforcement, where unprofessional actors use spectrum in an unauthorized way, in lightly licensed environments like 80 GHz, or in regions where spectrum is expensive, and operators need insurance their costly spectrum asset is being protected.

Our FAS Expert System coupled with our ULS Data Correction service is a “must have” for anyone concerned with link reliability.

Aviat Participates in Field Testing on 6 GHz Unlicensed Devices with Ameren and EPRI

Determines Interference Effects of Unlicensed Devices on Licensed Microwave Links

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.

The FCC opened the 6 GHz band to Wi-Fi 6e and other unlicensed users today. In response, we launched our new FAS Expert System to help protect networks in the 6 GHz and other bands from interference.

Aviat’s FAS Expert System software is custom built to monitor and detect interference, perform trend analysis of the network over time to track the growth of interference, and isolate problem links often before noticeable impacts occur.

Check out the overview video of our FAS Expert System presented by Alphonso Arnal.

FAS Wi-Fi Testing Summary White paper: FAS Wi-Fi Testing Summary
The purpose of this document is to describe the laboratory tests executed to understand, create, validate, and refine the rules designed and implemented in the expert system. We will focus specifically on the WiFi interference tests as those are the most critical at this point due to the imminent opening by the FCC of the 6 GHz frequency band to WiFi and other unlicensed uses. While we have conducted numerous WiFi interferer tests in our labs, we will only present in this document one of the most representative sets capturing the different interference levels and the effects that they create in the PTP microwave link.

FAS Expert System White paper: FAS Expert System
White paper: For more than two years now, the FCC has been evaluating the necessity and feasibility of opening up the 6 GHz band to unlicensed users of a wide variety of devices. They’ve published multiple notices of their findings, and on April 2, 2020, FCC Chairman Ajit Pai issued a draft version of the official rules, allowing unlicensed operation in the 6 GHz band—over the entire 1,200 MHz spectrum of that band. A final vote on April 23 opened the door to Wi-Fi 6e.

How to protect mission critical communication links from Wi-Fi 6E interference

Point-to-point microwaves links are the de facto standard for connecting infrastructure over vast distances quickly and cost-effectively. Lower frequencies, like 6 GHz, allows a network to span long distances with high capacity while maintaining robust availability, especially during rain fade. These characteristics have led to rapid, widespread adoption with more than 40000 links in the 6 GHz frequency band deployed across the US.
