Gsm time hierarchy
WebOriginal GSM radio band is 900 MHz (GSM 900). Another band later added to it as DCS (Digital Cellular System) at 1800 MHz (DCS 1800). The most of the world (except North America) uses these bands. These bands are, however, are not available in North America as they were allocated to some other wireless services.
