Band Uses (1429 - 1525 MHz)

Wireless Medical Telemetry Service (WMTS)

The 608-614, 1395-1400, and 1429-1432 MHz bands are used for the Wireless Medical Telemetry Service (WMTS). WMTS devices operate in the land mobile service on a "licensed by rule" basis as one of the growing number of Citizens Band Radio Services.

The FCC defines WMTS as "a private, short distance data communication service for the transmission of patient medical information to a central monitoring location in a hospital or other medical facility. Voice and video communications are prohibited. Waveforms such as electrocardiograms (EKG) are not considered video."

The FCC intends for WMTS to be the modern replacement for conventional medical telemetry systems that operate on an unlicensed basis in FCC Part 15, or licensed and secondary under Part 90 rules. When it created WMTS, the Commission said that it does not anticipate making any more allocations to medical telemetry.

WMTS is unique among the CB Services as it is the first to require frequency coordination by FCC-selected entities. These coordinators record and monitor the locations and frequencies of WMTS equipment for interference control purposes. WMTS is co-primary with the radio astronomy service in this band, and WMTS operations must be coordinated with the National Science Foundation.

WMTS equipment is only permitted in health care facilities, and eligibility to operate the equipment is strictly limited to health care personnel. WMTS cannot legally be used in a moving vehicle, even an ambulance.

The 608-614 MHz spectrum is one of many restricted bands in which the FCC's Part 15 rules permit unlicensed devices to emit only very low level emissions.

Inmarsat

The Inmarsat system uses 1525-1559 MHz for the downlink, and 1626.5-1660.5 MHz for the uplink (2x34 MHz). The sub-band 1544-1545/1645.5-1646.5 MHz is reserved for safety & distress communications.

Inmarsat consists of three satellites in geostationary orbit that provide coverage over most of the Earth, excluding the polar regions. Inmarsat is used for a wide variety of purposes, including voice and data services to ships, in-flight telephone service to airplanes when over the oceans, and voice/data services through the "Broadband Global Access Network" (BGAN), using laptop-sized satellite terminals.

Standard LTE Bands

The following bands have been defined by 3GPP as standard LTE bands for Frequency Division Duplex (FDD, where mobile and base stations transmit in separate bands) and Time Division Duplex (TDD, where mobiles and bases transmit and receive on the same frequency). These bands are defined in 3GPP TS 36.101 (link below).

Note that bands 15 & 16 and 30-32 are not defined, and the FDD band 29 is used for downlink-only for carrier aggregation, so it has no corresponding uplink band.

Uplinks refer to the frequencies used for handsets and other user devices to transmit to the base station, and downlinks refer to frequencies used by base stations to transmit to the user devices.
