||First-generation cellular network. 1G networks are based on analog systems meant to carry voice only. These were developed around 1980. NMT, AMPS, and TACS are examples of 1G systems.
||Second-generation cellular network. 2G networks are an evolution of 1G networks that was introduced during the 1990s. 2G networks are digital in nature and provide a per-user bandwidth of up to 144 kb/s. GSM, IS-54/136, and IS-95 are examples of 2G systems.
||Third-generation cellular network. 3G networks can provide a per-user bandwidth of up to 2 Mb/s and can carry multimedia traffic. WCDMA and CDMA2000 are examples of 3G systems.
||Third Generation Partnership Project. A collaborative effort by a group of telecommunications associations to define the standards for 3G networks and for the development of WCDMA/UMTS.
||Third Generation Partnership Project 2. The standards body and organization that coordinates the development of 3G networks based on CDMA2000.
||Fourth-generation cellular network. 4G networks are an evolution of 2G and 3G cellular networks; they are being defined as part of IMT-2000 and can provide a per-user bandwidth of up to 100 Mb/s.
||Authentication, Authorization, and Accounting. AAA is a generic model for IP network access control, initiated and developed by the IETF (de Laat et al., 2000).
||Authentication Header. The AH is a component of the IPSec protocol suite (Kent and Seo, 2005) that guarantees connectionless ...|
