TV White Space Devices

Current Use
470–614 MHz Fixed and personal/portable white space devices
TV white space devices are unlicensed intentional radiators that operate on available TV channels in the broadcast television frequency bands. Channel availability is determined from geospatial information and a TV bands database.

White space devices in the U.S. are governed by Part 15(H) of the FCC's rules. They operate on available TV channels in the broadcast television frequency bands, the 600 MHz band (including the guard bands and duplex gap), and in 608-614 MHz (channel 37).

TV white spaces has not been a commercial success and very few devices are in operation.

WRC Agenda Item 1.5, ITU Region 1

Proposed Use
470–960 MHz Review spectrum use and needs in Region 1 470–694 MHz Possible regulatory actions in Region 1
"to review the spectrum use and spectrum needs of existing services in the frequency band 470-960 MHz in Region 1 and consider possible regulatory actions in the frequency band 470-694 MHz in Region 1 on the basis of the review in accordance with Resolution 235 (WRC-15)"

Radio Astronomy (608-614 MHz)

Current Use
608–614 MHz Radio Astronomy (continuum observations)
The band 608-614 MHz, which would otherwise be TV channel 37 in the United States, is reserved for radio astronomy and wireless medical telemetry devices (see separate entry on WMTS).

Radio astronomers use this band for continuum (wide bandwidth) observations of celestial radio sources. Its location in the radio spectrum is strategically located between the next lower and next higher radio astronomy bands, in order to best characterize frequency-dependent changes in cosmic emissions.

See the IEEE Broadcast Technology Society newsletter article for more information on the history and use of this band for radio astronomy.

Wireless Medical Telemetry Service (WMTS)

Current Use
608–614 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.

3GPP 4G/5G Bands

Current Use
612–652 MHz 3GPP 5GNR FDD band N105 Downlink (APT 600)
3GPP is the global standards organization for 4G LTE and 5G NR radio technologies. It designates multiple bands throughout the radio spectrum for 4G/5G use. Different combinations of bands are used in different countries and regions.

Bands designated with a "B" are standardized for 4G LTE; bands designated with an "N" are 5G. Some bands are designated for both.

Frequency Division Duplex (FDD) uses paired bands, where one band is used for downlink (DL) transmissions from the base station to the user terminal (i.e., handset), and the other band is used for uplink (UL) transmissions from the user terminal to the base station.

Time Division Duplex (TDD) uses the same band for both uplink and downlink, which share the same frequency in time over ~millisecond timescales.
