NOTE 1: The term GSM 400 is used for any GSM system, which operates in any 400 MHz band, including T-GSM 380.

NOTE 4: The term GSM 900 is used for any GSM system, which operates in the frequency band 876-915 MHz in the UL and 921-960 MHz in the DL.

NOTE 5: The BTS may cover a complete band, or the BTS capabilities may be restricted to a subset only, depending on the operator needs.

NOTE 6: The term ER-GSM 900 is used for the GSM system, which in addition to GSM 900 operates in the frequency band 873-876 MHz in the UL and 918-921 MHz in the DL.

For T-GSM 810 the requirements for GSM 900 shall apply, apart for those parameters for which a separate requirement exists.

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

The channel 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 for the dynamically mapped ARFCNs:

Table 2-1 Dynamically mapped ARFCN

T-GSM 380	Fl(n) = 380.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n)=Fl(n) + 10
T-GSM 410	Fl(n) = 410.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n)=Fl(n) + 10
T-GSM 810	Fl(n) = 806.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n)=Fl(n) + 45
GSM 710	Fl(n) = 698.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n) = Fl(n) + 30

DCS 1 800	Fl(n) = 1710.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n) = Fl(n) + 95
PCS 1 900	FI(n) = 1850.2 + 0.2*(n-x+y)	x  n  x+z	Fu(n) = FI(n) + 80

where the applicable band is indicated by the GSM_Band parameter, x = ARFCN_FIRST, y = BAND_OFFSET and z = ARFCN_RANGE (See 3GPP TS 44.018). Parameters defining carrier frequencies not belonging to the indicated band shall not be considered erroneous.

Information about dynamic mapping is provided by System Information type 15 or Packet System Information type 8 if PBCCH exists, and optionally by System Information type 14. Dynamic ARFCN mapping shall be valid for the whole PLMN. Dynamic mapping has priority over the fixed designation of carrier frequencies. The support of dynamic ARFCN mapping is optional for all other mobile stations except those supporting GSM 700 and T-GSM.

Fl(n) and Fu(n) for all other ARFCNs:

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, EC-BCCH 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.
