System Bandwidths
2.3.2 Variable Bandwidth Systems
The 1800 MHz DCS (GSM) and 1900 MHz CDMA, TDMA, and GSM systems have
a bandpass filter that can be positioned within the uplink and downlink bands. This
position is specified when the equipment is ordered and it is set during manufactur-
ing.
1800 MHz DCS (GSM) System Bandwidth
The 1800 MHz DCS (GSM) 30 MHz bandpass filter is positioned within the 75 MHz
band during manufacturing.
You can choose where to place the 30 MHz band of operation, as shown in the fol-
lowing table
