The Low Power Radio Service or LPRS.

LPRS is a private, one-way short-distance communication service providing auditory assistance to persons with disabilities, persons who require language translation, and persons in educational settings, health care assistance to the ill, law enforcement tracking services in cooperation with a law enforcement agency, and point-to-point network control communications for Automated Marine Telecommunications System (AMTS) coast stations. Two-way voice communications are prohibited. Use of these frequencies is common on college campuses for wireless auditory assistance systems, audience participation systems and similar technology.

260 overlapping channels (wideband and narrowband) 216-217 MHz. Channels 19, 20, 50, and 151-160 are available exclusively for law enforcement tracking purposes. AMTS transmissions are limited to the 216.750-217.000 MHz frequency band for low power point-to-point network control communications by AMTS coast stations. Other AMTS transmissions in the 216-217 MHz frequency band are prohibited.

Channels 1-40 are standard band channels (25 kHz bandwidth), channels 41-60 are extra band channels (50 kHz bandwidth) and channels 61-260 are narrowband channels (4 kHz bandwidth). LPRS stations operating as part of an AMTS may use the 216.750-217.000 MHz frequency range as a single 250 kHz bandwidth channel.

The ERP of a LPRS transmitter must not exceed 100mW, unless the LPRS transmitter is part of an AMTS station/network. The ERP of a LPRS transmitted used with an AMTS station must not exceed 1 Watt.

See FCC rules Part 95 Subpart G - Low Power Radio Service 47 CFR 95.2101 through 47 CFR 95.2195. FCC rules Part 80 (Maritime Service) also apply in regards to the AMTS. See also: the VHF marine service and MF/HF marine mobile (maritime mobile) service.
