Wireless medical telemetry has worked fairly well for many years as the secondary users of the RF spectrum between the high power channels for the Private Land Mobile Radio Service (PLMRS) and on vacant local television channels. According to the FCC rules,as the secondary users of the spectrum, medical telemetry users must accept interference but not cause EMI to the licensed primary spectrum users (e.g., the TV broadcasters). In general, the low radio output power of medical telemetry poses little threat to the highpower broadcasters, and for many years there were adequate numbers of low-power PLMRS channels and unused TV channels (because the older analog TV broadcasts required vacant spectrum between channels). Thus, in a real sense the TV broadcasters of soap operas about hospitals had more rights to use the airways than the hospital transmitting vital signals from actual patients.
