Cellular Communication Cellular Communication Cellular communication is designed to provide communications between two moving units, or between one mobile unit and one stationary phone or land unit PSTN.
A burst is put in a TDMA-timeslot. Any telecommunications network requires some kind of NMS. This burst format is used by SCH channel only.
There are a number of channels which are reserved and not used for traffic or control. Wireless Signaling and Intelligent Networking 3 Wireless Signaling and Intelligent Networking The first two chapters provided an introduction to the history of mobile communications, its evolution, and the wireless industry standards process.

Medium Capacity Cell example: Eng Page 3 of 7. There are more on this later. All other frequencies are mostly for traffic but can also be used for control channels.
A list of such combinations is given below.
This optional feature empowers the carrier More information. Digital cellular telecommunications system, Global System for Mobile More information. Short introduction More information. One of those frequency channels is defined as the base-frequency beacon frequency or BCCH frequency. IKT Course title: That uplink contains RACH channel in this example see the figure below.
Few important features of the burst is stated below.
