How can the answer be improved? GSM Radio / Air Interface | GSM Slot & Burst | Electronics GSM slot structure. It has a defined format because a variety of different types of data are required to be transmitted. Although there are shortened transmission bursts, the slots is normally used for transmitting 148 bits of information. This data can be used for carrying voice data, control and synchronisation data. GSM Timeslot and Frequency Specifications - RF Cafe GSM Timeslot & Frequency Specifications. A GSM Multiframe is the basic unit, and is 120 ms long. There are 26 Frames in each Multiframe, with each Frame being 4.61538 ms long (120 ms/26). Within each Frame are 8 Timeslots at 576.92 μs per Timeslot (577 μs in round numbers). Finally, there are 156.25 Bits per Timeslot, each Bit being 3.69231 μs long. GSM EDGE RF Interface: Modulation, Slot, Burst The GSM EDGE radio interface or air interface is very similar to that of GSM, but adopts the different modulation scheme to enable it to carry the packet data more effectively. Being based upon the basic GSM slot and burst format, the EDGE interface is able to operate alongside GSM and GPRS signals.
