Question

The transmitted signal in a GSM system is of 200 kHz bandwidth and 8 users share a common
bandwidth using TDMA. If at a given time 12 users are talking in a cell, the total bandwidth of the
signal received by the base station of the cell will be at least (in kHz) ________.

Answer 1

HEY DEAR ...

I think the answer of your question is 400 KHZ .

HOPE , IT HELPS ...

Answer 2

the total bandwidth of the  signal received by the base station of the cell will be at least 400 kHz

Given bandwidth = 200 kHz

8 users can share a common bandwidth of 200 kHz.

Number of user present = 12

number of users extra = 12 - 8 = 4

For 4 user extra 200 kHz of bandwidth is required.

Total bandwidth = 200 + 200 = 400 kHz

Hence total bandwidth of the signal received  400 kHz
