Universal Mobile Telecommunications System (UMTS) Protocols and Protocol
Testing, Universal Mobile Telecommunications System (UMTS) is envisioned as the
successor to Global System for Mobile Communications (GSM). UMTS signals the
move into the third generation (3G) of mobile networks. UMTS, also referred to
as wideband code division multiple access (W–CDMA), is one of the most
significant advances in the evolution of telecommunications into 3G networks,
