GSM(Global Systems for Mobile)
Global System for Mobile: One of the world’s main second generation (2G) digital wireless 
standards.It is a European standard. It was developed by CEPT(Conference of European Posts and Telecommunications)
GSM is used in over 170 countries to cover Over 400 GSM network operators,Over 550 million 
people were subscribers to GSM.GSM as an OSI related model. GSM uses Gaussian Minimum Shift Keying (GMSK).GSM 900 uses 50 MHz in two 25 MHz bands for up 
and down links.
GSM functions in three bottom layers of the OSI model :
Physical  Data-Link  Layer 3

Goals of GSM:
It improved spectrum efficiency
It support International roaming
Low-cost mobile sets and base stations
High-quality speech
Compatibility with ISDN and other telephone company services.
Support for new services
GSM Architectures is three broad parts 
1. Subcribers carries MOBILE STATION 2. BSS controls  3. Network Subsystems
Acronyms in GSM:
MS : Mobile Station  BTS : Base Transceiver Station  BSC : Base Station Controller  MSC : Mobile-services Switching Center  VLR : Visitor Location Register  HLR : Home Location Register  AUC : Authentication center  EIR : Equipment Identity Register
