The 2G cellular system GSM 900 operates its 125 forward channels in the uplink frequency band 890.2-915 MHz and 125 reverse channels in the frequency band 935.2-960 MHz. Each channel has a bandwidth of 200 kHz. i. What is the bandwidth in the forward channels (uplink frequency band) and reverse channels (downlink frequency band)? ii. If each channel is subdivided into 16 time slots, what is the sub channel spacing? If each channel is shared by 16 users then compute the total number of users per cell?
