History Fourth-Generation 4G Technology. This term is generally used to refer to the development of mobile phone technology. The History Fourth-Generation 4G Technology is the development of 3G technology. The official name of this 4G technology by the IEEE (Institute of Electrical and Electronics Engineers) is "3G and beyond". 4G technology is a term borrowed from English: fourth-generation technology. This term is generally used to describe the development of mobile phone technology.
The first generation: most of the system in this generation is an analog system with a low velocity (low-speed) and sound as the main object. Example: NMT (Nordic Mobile Telephone) and AMPS (Analog Mobile Phone System). The second generation: used as a commercial standard digital format, low speed-high.
Example: GSM and CDMA2000 third 1xRTT. Generation: digital, capable of transferring data at high speed (high-speed) and multimedia applications, for broadband (broadband). Example: W-CDMA (also known as UMTS) and CDMA2000 1xEV-DO. Between second generation and third generation, often inserted the 2.5 generation of digital, high speed (up to 150 Kbps).
The technology in this category is 2.5 G of data-based services such as GPRS (General Packet Radio Service) and EDGE (Enhance Data rate for GSM Evolution) in the GSM domain and PDN (Packet Data Network) in the CDMA domain. 4G is the development of 3G technology. The official name of this 4G technology by the IEEE (Institute of Electrical and Electronics Engineers) is "3G and beyond".
Before History Fourth-Generation 4G Technology, High-Speed Down link Packet Access (HSDPA) is sometimes referred to as 3.5 G technology has been developed by the WCDMA the same as EV-DO CDMA2000 develop. HSDPA is a mobile telephony protocol provides network evolutionary paths for Universal Mobile Telecommunications System (UMTS) which will provide more data capacity of large (up to 14.4 Mbit / sec at the falls).
