GSM Network

GSMe When you use your mobile phone, you're connecting to a mobile network. Ever wonder how GSM networks work, and how your phone is identified on that network? NETWORK A A GSM networks (which cover 80% of the world's mobile users) consist of "cells," radio networks centered around Base Transceiver Stations In densely populated urban areas, BTS are more closely grouped and cells are much smaller and numerous. Additional (BTS) and their towers. In rural areas, BTS increase capacity and help manage the higher traffic in heavy call areas. each BTS can reach a maximum of 45 miles/ 70 kilometers depending on terrain. GSM phones search for a signal to connect to a BTS, moving among cells to find the strongest signal. Each BTS contains a tower/antenna, transceivers, signal processors, GPS/timing receivers, a power source, and a base station controller. GSM phones connect to each BTS via a signal, finding available frequencies. The BTS knows that a mobile phone is connecting to it by identifying the unique IMSI (International Mobile Subsciber Identity) and IMEI (International Mobile Equipment Identity) of those phones. Handsets are identified on the network by their unique IMEI number. Mobile phones on the GSM network use SIM (Subscriber Identity Module) cards – uniquely identifying, detachable smart cards that contain the user's subscription information. Each SIM card has a unique IMSI number that authenticates the user.
