2.2. Supported Bands
The Fastrack Xtend comes in several variants, supporting various bearers and bands. The FXT001,
FXT002, FXT006 and FXT007 are quad band programmable gateways that support either EU bands
(EGSM900/DCS1800) or US bands (GSM850/PCS1900). Users may switch from one supported band
to another by using AT commands.
The FXT003 and FXT008 are also quad band EGSM900/DCS1800/GSM850/PCS1900 that also
supports Tri Band WCDMA/FDD (850/1900/2100) (Band I, II, V) UMTS/HSxPA. Band selection is
done automatically without having to switch manually using AT commands. FXT004 is the CDMA
version, which supports dual band (800/1900 MHz) mode.
Refer to sections 9.4 Checking the Band Selection and 9.5 Switching Bands for more information
