# Gsm time slots and burst

Introduction GSM divides up each ARFCN into 8 time slots. These 8 timeslots are further broken up into logical channels. Logical channels can be thought of as just different types of data that is transmitted only on certain frames in a certain timeslot. Reliability of the GSM-R Communication System against Railway ... As in the case of the GSM, the frequency spacing between each physical channel is 200 kHz. It is also a Time Division Multiple Access (T DMA) system: for each carrier frequency, data transmission is made of periodical TDMA frames. Each frame is divided in 8 time slots (T S) of 577 µs and has a period of 4.615 ms.

## Extended Range

Adaptive time frame alignment is a technique designed to equalize propagation delay differences between MSs at different distances. The GSM system is designed to allow for cell sizes up to 35 km radius. The time a radio signal takes to travel the 70 km from the base station to the mobile station and back again is $$233.3 \mu s\ .$$ What is TDMA ? An explanation of TDMA - satsig.net TDMA burst time plan. The allocation of bursts to time slots within the TDMA frame is the burst time plan. As shown above the plan is: VSAT site 1 start 0 mS, time allocated 180 mS VSAT site 2 start 200 mS, time allocated 80 mS VSAT site 3 start 300 mS, time allocated 180 mS VSAT site 4 start 500 mS, time allocated 280 mS GSM-EDGE Test Signal: GSM_TSIG - awrcorp.com The Element Options dialog box General Information tab allows you to specify the general configuration of the test signal. The configuration of the time slots can also be set to match several of the required measurements found in the GSM specifications.

### GSM Transmit Frequencies. GSM-like systems have been specified for the 900 MHz ( GSM), 1800 MHz (DCS-1800) and 1900 MHz (PCS-1900Mobile terminals transmit in bursts of 577 microseconds. One burst fits into one time slot. Through feedback signals, the system can ensure that the signals...
