How to gsm mobile phone tracking

 

GSM ( Global System for Mobile Communications , originally Groupe SpécialMobile ) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation ( 2G ) digital cellular networks used by mobile phones , first deployed in Finland in July 1992. [2] As of 2014 [update] it has become the de facto global standard for mobile communications – with over 90% market share, operating in over 219 countries and territories. [3]

2G networks developed as a replacement for first generation ( 1G ) analog cellular networks, and the GSM standard originally described as a digital, circuit-switched network optimized for full duplex voice telephony . This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS).

Subsequently, the 3GPP developed third-generation ( 3G ) UMTS standards followed by fourth-generation ( 4G ) LTE Advanced standards, which do not form part of the ETSI GSM standard.
