| | |  GSM frequency ranges: Encyclopedia II - Global System for Mobile Communications - Radio interfaceGSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. GSM networks operate at various different radio frequencies. Most GSM networks operate at 900 MHz or 1800 MHz. The exception to the rule are networks in parts of the Americas (including the USA and Canada) that operate at 850 MHz or 1900 MHz.
In the 900 MHz band the uplink frequency band is 890-915 MHz, and the downlink frequency band is 935-960 MHz. This 25 MHz bandwidth is subdivided into 124 carrier frequencies, ...

| | | | GSM frequency ranges: Encyclopedia II - Global System for Mobile Communications - Market situation More than 1.6 billion people use GSM phones as of 2005, making GSM the dominant mobile phone system worldwide with about 70% of the world's market. GSM's main competitor, cdmaOne, is used primarily in North America and [2] parts of Asia. cdmaOne also benefited from increased radio spectrum efficiencies as compared to the more common GSM networks. Roaming with GSM phones is a major advantage over the competing technology as roaming across CDMA networks from different operators i ...

| | | | GSM frequency ranges: Encyclopedia II - Global System for Mobile Communications - History Throughout the evolution of cellular telecommunications, various systems were developed without the benefit of standardized specifications. This presented many problems directly related to compatibility, especially with the development of digital radio technology. In 1982, The GSM group ("Groupe Spécial Mobile" (French) 1, 2, 3 and 4) was formed to address these problems. The name of the system comes from the name of this group, though later the decision was made to keep the initials but to c ...

| | | | GSM frequency ranges: Encyclopedia II - GSM frequency ranges - GSM frequency usage in the Americas In North America, GSM operates on the primary mobile communication bands - 850 MHz and 1900 MHz. Initial implementations were exclusively 1900 MHz, with 850 MHz being added in 2001. In Canada, GSM-1900 is the primary frequency used in urban areas with 850 as a backup, and GSM-850 being the primary rural frequency. In the United States, regulatory requirements determine which area can use which frequency.
GSM-1900 and GSM-850 are also used in parts of South and Central America. At least one country there uses ...
