A family of standards to describe the protocols for second-generation (2G) digital cellular networks, GSM was developed by the European Telecommunications Standards Institute (ETSI) as a replacement for first-generation (1G) analog cellular networks. The original GSM standard described a digital, circuit-switched network optimized for full duplex voice telephony, employing time division multiple access (TDMA) between stations.
History and Evolution
GSM was initially developed to standardize digital cellular networks across Europe. Over time, it expanded to include data communications, first through circuit-switched transport and later through packet data transport via its upgraded standards, General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE).
- ETSI: The European Telecommunications Standards Institute developed the original GSM standard.
- GPRS: The first upgrade to GSM, enabling packet data transport.
- EDGE: A further upgrade to GPRS, providing enhanced data rates.
GSM Association
The GSM Association, now known as the GSMA, is an industry organization representing the interests of mobile network operators worldwide. It owns the GSM trademark and plays a crucial role in the development and promotion of mobile technologies.
Applications
GSM technology is used by mobile devices such as mobile phones and mobile broadband modems. It supports voice telephony and data communications, making it a foundational technology for mobile networks globally.
