1G
First Generation wireless technology. Based on analog or AMPS technology, 1G wireless networks were designed to carry voice traffic only.
1X - CDMA2000 1X, 1XRTT
Third-generation wireless technology that offers enhanced voice and data capacity and higher data rates than previous, second-generation wireless technologies. 1X is an evolution of cdmaOne®.
2G
Second-generation wireless technology. Based on digital technology, 2G wireless networks offer increased voice quality and capacity over 1G systems. 2G systems traditionally supported voice and circuit-switched data service. 2G systems are being replaced today by 2.5G and 3G networks.
2.5G
Based on digital technology, adding 2.5G wireless technology to a 2G network provides packet-data service and improved data rates. 2.5G technology has been implemented as GPRS.
3DES
Triple Data Encryption Standard. A private key symmetric cryptographic algorithm, that protects computer data by encoding the data three times for greater security. 3DES was issued as a Federal Information Processing Standard and is an updated version of DES.
3G
Third-generation wireless technology. Based on digital technology, 3G wireless networks offer increased voice capacity and provide higher data rates than 2G and 2.5G networks. As defined by the International Telecommunications Union (ITU), 3G technology has been or will be implemented as CDMA2000®, CDMA2000 1xEV-DO, WCDMA/UMTS and HSDPA/HSUPA.
3GPP
Third Generation Partnership Project, the standards body that oversees WCDMA.
3GPP2
Third Generation Partnership Project 2, the standards body that oversees CDMA2000.
4GV™
Fourth-Generation Vocoder™. Enables operators to prioritize voice quality and network capacity. Can be used to improve delay-sensitive applications such as VoiP (Voice over internet Protocol).
802.11 - a.k.a. Wi-Fi
802.11 refers to the body of standards issued by the IEEE for WLANs (wireless local area networks). 802.11 technologies use an over-the-air interface to connect a device (for example, a Wi-Fi enabled laptop) and an access point to another network. The 802.11 family of technologies includes 802.11a, 802.11b, 802.11g and 802.11n.
