Footnotes

  • 5.317A   The parts of the frequency band 698-960 MHz in Region 2 and the frequency bands 694-790 MHz in Region 1 and 790-960 MHz in Regions 1 and 3 which are allocated to the mobile service on a primary basis are identified for use by administrations wishing to implement International Mobile Telecommunications (IMT) – see Resolutions 224 (Rev.WRC 19), 760 (Rev.WRC 19) and 749 (Rev.WRC 19), where applicable. This identification does not preclude the use of these frequency bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. (WRC-19)

  • 5.322   In Region 1, in the band 862-960 MHz, stations of the broadcasting service shall be operated only in the African Broadcasting Area (see Nos. 5.10 to 5.13) excluding Algeria, Burundi, Egypt, Spain, Lesotho, Libya, Morocco, Malawi, Namibia, Nigeria, South Africa, Tanzania, Zimbabwe and Zambia, subject to agreement obtained under No. 9.21. (WRC 12)

  • 5.323   Additional allocation: in Armenia, Azerbaijan, Belarus, the Russian Federation, Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan and Ukraine, the frequency band 862-960 MHz, in Bulgaria the frequency bands 862-880 MHz and 915-925 MHz, and in Romania the frequency bands 862-880 MHz and 915-925 MHz, are also allocated to the aeronautical radionavigation service on a primary basis. Such use is subject to agreement obtained under No. 9.21 with administrations concerned and limited to ground-based radiobeacons in operation on 27 October 1997 until the end of their lifetime. (WRC 19)

  • 5.325   Different category of service: in the United States, the allocation of the band 890-942 MHz to the radiolocation service is on a primary basis (see No. 5.33), subject to agreement obtained under No. 9.21.

  • 5.327   Different category of service: in Australia, the allocation of the band 915-928 MHz to the radiolocation service is on a primary basis (see No. 5.33).

  • G2   In the bands 216.965-216.995 MHz, 420-450 MHz (except as provided for in G129), 890-902 MHz, 928-942 MHz, 1300-1390 MHz, 2310-2390 MHz, 2417-2450 MHz, 2700-2900 MHz, 3300-3500 MHz, 5650-5925 MHz, and 9000-9200 MHz, use of the Federal radiolocation service is restricted to the military services.

  • US116   In the bands 890-902 MHz and 935-941 MHz, no new assignments are to be made to Federal radio stations after July 10, 1970, except on case-by-case basis to experimental stations. Federal assignments existing prior to July 10, 1970, shall be on a secondary basis to stations in the non-Federal land mobile service and shall be subject to adjustment or removal from the bands 890-902 MHz, 928-932 MHz, and 935-941 MHz at the request of the FCC.

  • US268   The bands 890-902 MHz and 928-942 MHz are also allocated to the radiolocation service for Federal ship stations (off-shore ocean areas) on the condition that harmful interference is not caused to non-Federal land mobile stations. The provisions of footnote US116 apply.

WRC Agenda Item 1.5, ITU Region 1

Proposed Use
470–960 MHz Review spectrum use and needs 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)"

Military Shipborne Very Long Range Surveillance Radar

Current Use
850–942 MHz Military shipborne very long range surveillance radar
The Raytheon AN/SPS-49 series very long range surveillance radar is installed on many ships of the U.S. fleet, as well as several other countries. It operates with 360 kW peak power and 13 kW average power, using a 24 ft wide by 14 ft tall antenna rotating with a period of 12 rotations per minute (one rotation every five seconds). The antenna gain is 28.5 dBi with an azimuth beamwidth of 3.4 deg. The radar can detect objects as close as 0.5 nmi, and as far as 250 nmi. The antenna is stabilized for up to +/-25 deg roll.

Radiofrequency Identification (RFID)

Current Use
860–960 MHz RFID (ITU Regions 1 & 3)
An RFID system consists of an interrogator and a transponder, and is used for identification and data capture. RFID systems are used for a very wide range of applications, including:

Highway tolls
Vehicle tracking
Container tracking
Inventory control & theft prevention (often used to prevent shoplifting)
Healthcare (patient & drug tracking)
Passports
ID cards
Building entry
Livestock & pet tracking

and numerous other applications.

RFID tags can be extremely small devices with little or no internal power, which respond to an interrogation by utilizing some of the RF energy imparted by the interrogator; or they can be larger powered units that can be interrogated over larger distances.

The ITU is in the process of attempting to harmonize RFID bands, since RFID systems are used for global commerce. ITU Study Group 1 (Working Party 1B) is drafting a new ITU-R Recommendation on RFID.

ISO/IEC18000 is the principal standard for the RFID air interface.

RFID systems typically operate in ISM and unlicensed bands.

The bands listed below represent the totality of the various bands presently used around the world. The exact bands used in specific countries may vary (and is what the ITU is attempting to harmonize).

Standard LTE Bands

Current Use
925–960 MHz LTE band 8 FDD downlink
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.
