GSM stands for "Global System for Mobile communications", which was a replacement for the former AMPS and TDMA (Time Division Multiple Access) formats of analog cellular telephone transmissions.
GSM is currently used by over 3 billion people across more than 212 countries and territories, over 82% of the world's population.
GSM's advantage over its predecessor is that it is 100% digital, as opposed to TDMA, which was analog. While covering a shorter distance than the analog signal, a GSM signal can carry more voice and data communications than the analog band, and carry it at a faster rate, thus making GSM a "second-generation" (2G) cellular technology.
Most GSM networks operate in the 900 MHz or 1800 MHz bands. Some countries in the Americas (including Canada and the United States) use the 850 MHz and 1900 MHz bands because the 900 and 1800 MHz frequency bands were already allocated.

What are the merits and demerits of GSM?
Advantages of 2G GSM * GSM is mature; this maturity means a more stable network with robust features. * Less signal deterioration inside buildings. * Ability to use repeaters. * Talktime is generally higher in GSM phones due to the pulse nature of transmission. * The availability of Subscriber Identity Modules allows users to switch networks and handsets at will. * GSM covers virtually all parts of the world so international roaming is not a problem. [edit] Disadvantages of 2G GSM * Pulse nature of TDMA transmission used in 2G interferes with some electronics, especially certain audio amplifiers. 3G uses W-CDMA now. * Intellectual property is concentrated among a few industry participants, creating barriers to entry for new entrants and limiting competition among phone manufacturers. * GSM has a fixed maximum cell site range of 35 km, which is imposed by technical limitations.

What is difference between 2G and 2.5G?
2G is GSM whereby each user has a defined time slot to access the base station whereas in 2.5G, also known as GPRS, it is the aggregation of time slots to create a data packet for a user. GPRS is the first step towards a mobile data service.
