  • US350   In the band 1427-1432 MHz, Federal use of the land mobile service and non-Federal use of the fixed and land mobile services is limited to telemetry and telecommand operations as described further:

        (a) Medical operations. The use of the band 1427-1432 MHz for medical telemetry and telecommand operations (medical operations) shall be authorized for both Federal and non-Federal stations.

            (1) Medical operations shall be authorized in the band 1427-1429.5 MHz in the United States and its insular areas, except in the following locations: Austin/Georgetown, Texas; Detroit and Battle Creek, Michigan; Pittsburgh, Pennsylvania; Richmond/Norfolk, Virginia; Spokane, Washington; and Washington DC metropolitan area (collectively, the “carved-out” locations). See Section 47 C.F.R. 90.259(b)(4) for a detailed description of these areas.

            (2) In the carved-out locations, medical operations shall be authorized in the band 1429-1431.5 MHz.

            (3) Medical operations may operate on frequencies in the band 1427-1432 MHz other than those described in paragraphs (a)(1) and (2) only if the operations were registered with a designated frequency coordinator prior to April 14, 2010.

WRC-27 possible allocations for low-data rate NGSO MSS systems

Proposed Use
1427–1432 MHz WRC-27 possible allocations for low-data rate NGSO MSS systems
WRC-27 agenda item 1.12:

to consider, based on the results of studies, possible allocations to the mobile-satellite service and possible regulatory actions in the frequency bands 1 427-1 432 MHz (space-to-Earth), 1 645.5-1 646.5 MHz (space-to-Earth) (Earth-to-space), 1 880-1 920 MHz (space-to-Earth) (Earth-to-space) and 2 010-2 025 MHz (space-to-Earth) (Earth-to-space) required for the future development of low-datarate non-geostationary mobile-satellite systems, in accordance with Resolution 252 (WRC-23)

Standard LTE Bands

Current Use
1427.9–1447.9 MHz LTE band 11 FDD uplink
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.

Wireless Medical Telemetry Service (WMTS)

Current Use
1429–1432 MHz 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.
