First phase of third-generation (3G) mobile wireless technology for CDMA2000 networks.


Evolutionary phase of third-generation (3G) CDMA2000 networks, divided into two phases: 1XEV-DO (data only) and 1XEV-DV (data and voice).


Triple Data Encryption Standard. A 168-bit encryption algorithm that encrypts data blocks with three different keys in succession, achieving a higher level of encryption than is achieved with standard DES, and often implemented with cipher block chaining (CBC). 3DES is one of the strongest encryption algorithms available for use in virtual private networks (VPNs). Also called triple DES.


Third-generation Partnership Project. Created to expedite the development of open, globally accepted technical specifications for the Universal Mobile Telecommunications System (UMTS).
