FCC statements

There is an FCC statement on coexistence of WMTS in various frequency bands.

Prior to the establishment of the WMTS, medical telemetry devices generally could be operated on an unlicensed basis on vacant television channels 7-13 (174-216 MHz) and 14-46 (470-668 MHz) or on a licensed but secondary basis to private land mobile radio operations in the 450-470 MHz frequency band. This meant that wireless medical telemetry operations had to accept interference from the primary users of these frequency bands, i.e., the television broadcasters and private land mobile radio licensees. Further, if a wireless medical telemetry operation caused interference to television or private land mobile radio transmissions, the user of the wireless medical telemetry equipment would be responsible for rectifying the problem, even if that meant shutting down the medical telemetry operation.
