1. 3G Frequencies
3G Frequencies
According to "WARC-92 frequencies for IMT-2000" resolution: "The bands 1885-2025 MHz
and 2110-2200 MHz are intended for use, on a worldwide basis, by administrations wishing to
implement International Mobile Telecommunications-2000 (IMT-2000). Such use does not
preclude the use of these bands by other services to which they are allocated."
Here is the summary of UMTS frequencies:
1920-1980 and 2110-2170 MHz Frequency Division Duplex (FDD, W-CDMA) Paired uplink
and downlink, channel spacing is 5 MHz and raster is 200 kHz. An Operator needs 3 - 4 channels
(2x15 MHz or 2x20 MHz) to be able to build a high-speed, high-capacity network.
1900-1920 and 2010-2025 MHz Time Division Duplex (TDD, TD/CDMA) Unpaired, channel
spacing is 5 MHz and raster is 200 kHz. Tx and Rx are not separated in frequency.
1980-2010 and 2170-2200 MHz Satellite uplink and downlink.
Carrier frequencies are designated by a UTRA Absolute Radio Frequency Channel Number
(UARFCN). The general formula relating frequency to UARFN is:
UARFCN = 5 * (frequency in MHz)
WRC-2000 in Istanbul
Identified the bands 1710 - 1885 and 2500 - 2690 MHz for IMT-2000
Identified those parts of the band 806 - 960 MHz which are allocated to the mobile service on a
primary basis
Admitted that High Altitude Platform Stations (HAPS) may use the WARC-92 frequency
bands for terrestrial IMT-2000 on restrictive conditions
Decided that the frequency bands 1525 - 1544, 1545 - 1559, 1610 - 1626.5, 1626.5 - 1645.5,
1646.5 - 1660.5 and 2483.5 - 2500 MHz may be used for the satellite component of IMT-2000,
as well as the bands 2500 - 2520 MHz and 2670- 2690 MHz, depending on market developments
Decided that "the bands, or portions of the bands, 1710 - 1885 MHz and 2500 - 2690 MHz, are
identified for use by administrations wishing to implement International Mobile
Telecommunications-2000 (IMT-2000). This identification does not preclude the use of these
bands by any application of the services to which they are allocated and does not establish
priority in the Radio Regulations".
