CHAPTER 2 - DESCRIPTION - OPERATION

2.1 REMINDERS ABOUT THE GENERAL CHARACTERISTICS OF GSM 900, DCS 1800 and PCS
1900
Table 1 below gives the characteristics of the radio interface for the GSM 900, DCS 1800 and
PCS 1900 systems :
Frequency Band (MHz)
Number of time intervals per TDMA
frame
Width 2 x W simplex (MHz)
Duplex spacing (MHz)
Modulation speed (kbit/s)
Speech throughput (kbit/s)
Maximum data throughput (kbit/s)
Multiple access
Cell radius (km)
SAGEM terminal power (W)
Table 2 shows powers as a function of the network:
