SDH, E1, microwave, satellite etc. 1-minute fast startup Support GSM900,DCS1800,EGSM and RGSM Support GSM PHASE 1、PHASE 2 and PHASE 2+ Support GPRS and EDGE Support baseband hopping and RF hopping Support FR, HR, EFR and AMR Support A5/1 and A5/2 encryption/decryption | GSM BTS312 Hardware Structure Objectives Upon completion of this course, you will be able to: Know the functions and features of BTS Master the BTS hardware structure Master the signal processing of BTS Page References BTS312 User Manual User Manual Page Contents Overview System Components Signal Processing Antenna and Feeder System Page Location MS: Mobile Station BTS: Base Transceiver Station OMC: Operation and Maintenance Center HLR: Home Location Register EIR: Equipment Identity Register MSC: Mobile Switching Center VLR: Visitor Location Register SMC: Short Message Center VM: Voice Mailbox BSC: Base Station Controller AUC: Authentication Center Page BTS is one of the most important parts in GSM system. It is the wireless part of the base station subsystem, and its position in the system is shown in this figure. BTS is a set of transceiving equipment that serves a certain cell and it is controlled by the BSC ( the base station controller). Connects with BSC through the Abis interface and connects MS through the Um interface. It helps BSC implement radio resources management, wireless parameter management and interface management.
