NOTE 1: The term GSM 400 is used for any GSM system, which operates in any 400 MHz band.

NOTE 2: The term GSM 850 is used for any GSM system which operates in any 850 MHz band.

NOTE 3: The term GSM 900 is used for any GSM system, which operates in any 900 MHz band.

NOTE 4: The BTS may cover a complete band, or the BTS capabilities may be restricted to a subset only, depending on the operator needs.

Operators may implement networks that operate on a combination of the frequency bands above to support multi band mobile terminals.

The carrier spacing is 200 kHz.

The carrier frequency is designated by the absolute radio frequency channel number (ARFCN). If we call Fl(n) the frequency value of the carrier ARFCN n in the lower band, and Fu(n) the corresponding frequency value in the upper band, we have:

P-GSM 900

Fl(n) = 890 + 0.2*n

1  n  124

Fu(n) = Fl(n) + 45

E-GSM 900

Fl(n) = 890 + 0.2*n

0  n  124

Fu(n) = Fl(n) + 45

Fl(n) = 890 + 0.2*(n‑1024)

975  n  1 023

R‑GSM 900

Fl(n) = 890 + 0.2*n

0  n  124

Fu(n) = Fl(n) + 45

Fl(n) = 890 + 0.2*(n‑1024)

955  n  1023

DCS 1 800

Fl(n) = 1710.2 + 0.2*(n‑512)

512  n  885

Fu(n) = Fl(n) + 95

PCS 1 900

FI(n) = 1850.2 + .2*(n-512)

512 £ n £ 810

Fu(n) = FI(n) + 80

GSM 450

Fl(n) = 450.6 + 0.2*(n-259)

259  n  293

Fu(n) = Fl(n) + 10

GSM 480

Fl(n) = 479 + 0.2*(n-306)

306  n  340

Fu(n) = Fl(n) + 10

GSM 850

Fl(n) = 824.2 + 0.2*(n-128)

128  n  251

Fu(n) = Fl(n) + 45

Frequencies are in MHz.

A multi-band MS shall interpret ARFCN numbers 512 to 810 as either DCS 1800 or PCS 1900 frequencies according to the parameter BAND_INDICATOR when received in other than the DCS 1800 or PCS 1900 bands. If received in the DCS 1800 or PCS 1900 bands, those ARFCN numbers shall be interpreted as frequencies in the same band. The BAND_INDICATOR is broadcast on BCCH, PBCCH and SACCH. The most recently received value shall be applied by the mobile station. If the parameter is not broadcast, the default value is DCS 1800 frequencies.
