UMTS - Universal Mobile Telecommunications System

UMTS is the Western European name for the 3G WCDMA standard adopted as an evolutionary path by the GSM world. However, it utilises the radio spectrum in a fundamentally different manner than GSM. UMTS is based on DCMA technology and the GSM standard is based on TDMA technology.
