The term Cellular is sometimes used to describe GSM services in the 850 MHz band, because the original analog cellular mobile communication system was allocated in this spectrum. In the United States, regulatory requirements determine which area can use which band. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band. In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. GSM-1900 and GSM-850 are used in most of North, South and Central America (ITU-Region 2). In some countries GSM-1800 is also referred to as "Digital Cellular System" (DCS). Mobile Communication Services on Aircraft (MCA) uses GSM-1800. GSM-900 and GSM-1800 are used in most parts of the world (ITU-Regions 1 and 3): Africa, Europe, Middle East, Asia (apart from Japan and South Korea where GSM has never been introduced) and Oceania.
