Capacity increase when reuse density is multiplied: Supposing there are 300 cells Bandwidth: 8 MHz (40 frequency) Normal 4*3 reuse: reuse den
Read MoreMulti-layer reuse pattern technology means to divide the whole frequency resources into different subgroups according to specific principles. Each sub
Read MoreThe basic frequency reuse mode of GSM is 4*3 frequency reuse. It is the basic of other frequency reuse modes, we also call it regular frequency reuse
Read MoreGSM is an interference restricted system. Carrier-to-interference ratio (C/I), also called interference protection ratio, refers to the ratio of all u
Read MoreBCC is a part of BSIC. For its function, please refer to above sections. BCC is composed of 3 bits. The available range is from 0 to 7. BSIC in
Read MoreTo uniquely identify each cell in the GSM PLMN, the network operator needs to allocate one code for each cell, which is the cell identity (CI). Cell i
Read MoreLocation Area Code(LAC) : To locate the location of MS, the whole area covered by each GSM PLMN is divided into different location areas. LAC is used
Read MoreNetwork identity parameters mainly include cell global identity (CGI) and base station identity code (BSIC). CGI=MCC+MNC+LAC+CI Once MS receives S
Read MoreTransmission delay is unavoidable in the radio interface. If the mobile station moves away from the base station during a call, the further distance t
