Many ULS coordinates are not accurate which means FCC may allow Wi-Fi 6 APs to be coordinated near actual tower locations. Licensees will have zero protection from interference if their FCC data is incorrect and that should be particularly troubling to critical infrastructure licensees. Find out how our data correction service can help you here.

The problem:

Pending new unlicensed usage in the 6 GHz band may cause interference to your current critical services. To deal with interference, it’s important to understand the main issues and how they affect your critical services.

Issues causing interference in 6 GHz unlicensed:

– FCC/ ULS data discrepancies

Currently, AFC (automatic frequency coordination) methods will be relied on to ensure new unlicensed services do not impact critical 6 GHz fixed point-to-point services already installed. To ensure accurate operation, AFC will require that the FCC data accurately reflects the reality of what’s deployed.

– No way to monitor interference

It’s one thing to report alarms and failures, however to fix the issue you need to be able to understand the root cause of the interference and analyze them before they become a major problem. Without the ability to monitor interference, you are constantly in reactive mode versus proactive operations. This may result in link degradation and outages on critical services.

– No way to document interference

The inability to document interference basically renders you blind to your network health, and unable to fight back. You need the ability to analyze baseline data to identify the root cause, and trend the interference to be protect your network.

Incorrect FCC/ULS data means…

AFC cannot protect fixed services resulting in possible interference and impacts to critical services in the 6 GHz band.

The result for you…

Zero protection! Licensees will have zero protection from interference if their FCC data is incorrect and that should be particularly troubling to critical infrastructure licensees.

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.
