4G


4G is an acronym of the words in English: fourth-generation technology. This term is generally used in reference to the development of mobile phone technology. 4G represents 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 words from English: fourth-generation technology. This term is generally used to describe the development of mobile phone technology.

Definition
4G systems will be able to provide a comprehensive IP solution where voice, data and multimedia flows can be up to users anytime and anywhere, on the average data higher than the previous generation. There are currently no formal definition for 4G. However, there are some opinions that are designated for 4G, namely: 4G will be a fully integrated IP-based systems. This will be achieved after wired and wireless technologies can be converted and capable of producing speeds and 1Gb/detik 100Mb/detik both inside and outside space with premium quality and high security. 4G will offer all kinds of services at affordable prices. Each handset will direct 4G IP v6 has a number equipped with the ability to interact with the Internet telephony-based Session Initiation Protocol (SIP). All types of radio transmissions such as GSM, TDMA, EDGE, CDMA 2G, 2.5G will be used, and can integrate easily with a radio that operated without a license, such as IEEE 802.11 in the frequency of 2.4GHz & 5-5.8Ghz, Bluetooth and cellular. Integration of voice and data in the same channel. Integration of voice and data-enabled SIP application.

History
The development of wireless technology can be summarized as follows:
• First generation: almost all systems in this generation is an analog system with low speed (low-speed) and sound as the main object. Example: NMT (Nordic Mobile Telephone) and AMPS (Analog Mobile Phone System).
• Second generation: used as a commercial standard digital format, low speed – medium. Example: GSM and CDMA2000 1xRTT.
• Third generation: digital, capable of transferring data at high speed (high-speed) and multimedia applications, to broad band (broadband). Example: W-CDMA (also known as UMTS) and CDMA2000 1xEV-DO.
Between the second generation and third generation, 2.5 generation are often inserted digitally, the medium speed (up to 150 Kbps). The technology categories at 2.5 G is a 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 represents 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 4G, High-Speed Downlink Packet Access (HSDPA), which is sometimes referred to as 3.5G technology has been developed by the WCDMA the same as CDMA2000 EV-DO development. HSDPA is a protocol that provides mobile phone network evolutionary paths for the Universal Mobile Telecommunications System (UMTS) that will be able to provide greater data capacity (up to 14.4 Mbit / second direction down).
