Emissions from spaceborne or airborne stations can be particularly serious sources of interference to the radio astronomy service (see Nos. 4.5 and 4.6 and Article 29). (WRC 07)

  • 5.341   In the bands 1 400-1 727 MHz, 101-120 GHz and 197-220 GHz, passive research is being conducted by some countries in a programme for the search for intentional emissions of extraterrestrial origin.

High Altitude Platform Station (HAPS)

Current Use
1885–1980 MHz HAPS service links for IMT in Regions 1, 2, & 3 (per 5.388A)
The ITU has identified various bands for use by High Altitude Platform Stations (HAPS), which are defined as "a station located on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth."

One set of bands (47.2-47.5 and 47.9-48.2 GHz) is identified on a worldwide basis. The others apply regionally or in a subset of countries.

Although there was a flurry of activity related to HAPS beginning in the late 1990's, no HAPS systems were ever developed. As of 2015, there is renewed interest in HAPS for applications involving telecommunications from Unmanned Aerial Systems (UAS).

HAPS is declared as an application of the fixed service.

Standard LTE Bands

Current Use
1910–1930 MHz LTE band 37 TDD 1920–1980 MHz LTE band 1 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.

European Union 3G & 4G (LTE) Band

Current Use
1920–1980 MHz European Union 3G & 4G band
In November, 2012, the European Commission adopted new rules clearing the way for the frequency band 1920-1980 MHz, paired with 2110-2170 MHz, to be used for 4G (LTE) services, in addition to its existing designated use for 3G services.
