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.

Standard LTE Bands

Current Use
859–894 MHz LTE band 26 FDD downlink 869–894 MHz LTE band 5 FDD downlink 875–890 MHz LTE band 19 FDD downlink 880–915 MHz LTE band 8 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.

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).

Cellular Radiotelephone Service

Current Use
880–890 MHz Cellular B block, base transmit/mobile receive
The 869-894 MHz band (base transmit/mobile receive), paired with the 824-849 MHz band (mobile transmit/base receive) is the original band in which first-generation cellular phone service was first widely deployed in the U.S. It is still used for 2G and 3G cellular services.

The paired band is subdivided into two smaller bands of 2x12.5 MHz each, referred to as the A block and the B block. When cell phone service was first authorized, the A block was assigned to the local exchange carrier, and the B block was assigned to a competitive local exchange carrier.

The cellular service in the United States is governed by Part 22 of the FCC's rules.
