Unlicensed device users at 902-928 MHz challenge LMS provider Progeny’s test results.
We reported back in February about a licensed service provider being required to demonstrate that its operation would not cause unacceptable interference to unlicensed devices. This is unusual. The FCC rules ordinarily require an unlicensed device to accept any and all interference from any source. But certain technologies used in the licensed Location and Monitoring Service (LMS) at 902-928 MHz are uniquely subject to a reversal of the usual priority. Those LMS licensees must demonstrate through actual field tests that their systems do not interfere with unlicensed devices.
