LocusUSA Receives New U.S. Patent for Analyzing Radio Performance Over-the-Air (OTA) While in Operation

“Our technology will allow agencies to feel confident their portable and mobile radios will work whenever and wherever they are needed,” said Joseph Rey, managing partner of LocusUSA.

LocusUSA, a leader in the area of RF (radio frequency) capture for alignment analysis and radio location, has been granted a new patent from the United States Patent and Trademark Office (USPTO). The U.S. patent, number 9681321B2, entitled “Method and System for Analyzing Radio Performance During Over-the-Air (OTA) Operation”, was issued in June 2017.

Automatic Frequency Control (AFC) is an embedded technology incorporated into most land mobile radio (LMR) systems to temporarily adjust specific metrics including frequency misalignment or error. A misaligned radio will experience issues connecting to the LMR system. As the radio continues to drift further out of alignment AFC will no longer engage resulting in a hard failure. A radio like this, even while appearing to be temporarily in spec, is a definite candidate for maintenance.

This new patent technique will identify how much AFC correction is being applied to a subscriber radio in real-time, while it is operational and deployed in the field. It measures the temporary AFC adjustment by capturing and analyzing all control channel transmissions from the radio and identifies, by Radio ID, which ones are in jeopardy of failing while in use.

“Our technology will allow agencies to feel confident their portable and mobile radios will work whenever and wherever they are needed,” said Joseph Rey, managing partner of LocusUSA. “It will enable them to experience a higher level of radio performance while reducing their annual radio maintenance costs.”

The company presently holds seven United States patents, three Australian patents, and one Canadian patent.
