3G wireless
Third generation (3G) wireless. Third generation wireless is a global framework that is implemented regionally in
Europe (UMTS), North America (CDMA2000) and Japan (NTT DoCoMo). 3G is designed for high-speed wireless

4G wireless
Fourth generation (4G) wireless. Fourth generation is successor to 3G and 2G standards. The nomenclature of the
generations generally refers to a change in the fundamental nature of the service. The first was the move from analogue
to digital (2G), which was followed by multi-media support (3G) and now 4G, which refers to all IP packet-switched
networks and increases in data s

Analog
Analog transmission uses energy waves to transmit information. In the case of wireless voice transmission, the sound
waves of a human voice are converted directly to specific, continuously variable characteristics of a radio wave.
