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)________.

\lceil \frac{\text{Total users}}{\text{Users per carrier}} \rceil = \lceil \frac{12}{8} \rceil = \lceil 1.5 \rceil = 2
