WebThe basic GSM frame defines the structure upon which all the timing and structure of GSM messaging and signalling is based. The fundamental unit of time is called a burst period and it lasts for approximately 0.577 ms (15/26 ms). Eight of these burst periods are grouped made a TDMA frame.

WebGSM Control Channels (CCH): There are three main control channels in the GSM system. These are the i) Broadcast CHannel (BCH), ii) The Common Control CHannel (CCCH), and the iii) Dedicated Control CHannel (DCCH) Each control channel consists of several logical pieces of information which is discussed in detail: WebGPRS uses FDMA to divide 25 MHz to 124 channels and each channel is further divided using TDMA into 8 time slots similar to GSM. Each of the frequency and time slot make one physical channel. We have seen that in GSM 26 Frame MF (Multiframe) and 51 Frame MF is used for traffic/SACCH and Signaling channels respectively. black pyramid jacket chris brownWebGSM Time Hierarchy is also known as GSM Frame Hierarchy.
