Introduction to Global System for Mobiles Seminar Topic:

The main objective of this paper is to give idea of global system mobile (GSM). In the earlier days, only telephones are present. These are wired and cannot be carried any where. So means of communication was difficult if the person is not available near the telephone. This Problem gave rise to cell phones which are wireless and can be carried everywhere.

These cell phones use GSM technology. The evolution of GSM is being grown day by day. Today this GSM technology is being covered even in the rural areas also apart from urban cites.

Brief into Solar Tracking system and Hybrid Power generation:

This GSM technology makes use of radio frequency waves. This has two frequency bands of 900MHZ band and 1800 MHZ band. GSM network has three subsystems, BSS, NSS and NMS. The combination of mobile equipment and SIM is considered as mobile station. The network switching subsystem consists of MSC,VLR, HLR. The MSC is used for controlling calls. VlR maintains the user location records and is temporary. HLR maintains the permanent subscriber information. The network switching subsystem controls the calls, locates the subscriber and mobility management.

The Base station subsystem has the responsibilities such as establishing a connection between mobile station and network switching subsystem, error free transmission and decoding the digital system into speech.  Two open air interfaces ‘Air Interface and A Interface’ are present. GSM uses three security algorithms A3, A5, A8. A3 and A8. These algorithms are present in the SIM. The aim of maintaining these security algorithms are to compare the data which is stored in the network and SIM.
