G - Wikipedia, the free encyclopedia. G, short for third generation, is the third generation of wireless mobile telecommunications technology. This is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications- 2. IMT- 2. 00. 0) specifications by the International Telecommunication Union. G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. G telecommunication networks support services that provide an information transfer rate of at least 2. Later 3. G releases, often denoted 3. G and 3. 7. 5G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies. A new generation of cellular standards has appeared approximately every tenth year since 1. G systems were introduced in 1. Each generation is characterized by new frequency bands, higher data rates and non. The first 3. G networks were introduced in 1. G networks in 2. 00. Overview. Services advertised as 3. G are required to meet IMT- 2. To meet the IMT- 2. Mbit/s). However, many services advertised as 3. G provide higher speed than the minimum technical requirements for a 3. G service. Recent 3. G releases, often denoted 3. G and 3. 7. 5G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. The following standards are typically branded 3. G: the UMTS (Universal Mobile Telecommunications Service) system, first offered in 2. GPP, used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by GSM (Global Systems for Mobile) 2. G system infrastructure. The cell phones are typically UMTS and GSM hybrids. Several radio interfaces are offered, sharing the same infrastructure. The original and most widespread radio interface is called W- CDMA (Wideband Code Division Multiple Access). The TD- SCDMA radio interface was commercialized in 2. China. The latest UMTS release, HSPA+, can provide peak data rates up to 5. Mbit/s in the downlink in theory (2. Mbit/s in existing services) and 2. Mbit/s in the uplink. CDMA2. 00. 0 system, first offered in 2. GPP2, used especially in North America and South Korea, sharing infrastructure with the IS- 9. G standard. The cell phones are typically CDMA2. IS- 9. 5 hybrids. The latest release EVDO Rev B offers peak rates of 1. Mbit/s downstream. The above systems and radio interfaces are based on spread spectrum radio transmission technology. While the GSM EDGE standard (. It is based on the three times as efficient 8. PSK modulation scheme as supplement to the original GMSK modulation scheme. EDGE is still used extensively due to its ease of upgrade from existing 2. G GSM infrastructure and cell- phones. However, in practice EDGE is seldom marketed as a 3. G system, but a 2. G system. EDGE shows slightly better system spectral efficiency than the original UMTS and CDMA2. GSM spectral bandwidth of 2. Hz, and it is thus a dead end. EDGE was also a mode in the IS- 1. TDMA system, today ceased. Evolved EDGE, the latest revision, has peaks of 1 Mbit/s downstream and 4. The Universal Mobile Telecommunications System, created and revised by the 3. GPP. The family is a full revision from GSM in terms of encoding methods and hardware, although some GSM sites can be retrofitted to broadcast in the UMTS/W- CDMA format. A few others use the 8. MHz bands. HSPA is backward- compatible with and uses the same frequencies as W- CDMA. HSPA+, a further revision and upgrade of HSPA, can provide theoretical peak data rates up to 1. Mbit/s in the downlink and 2. Mbit/s in the uplink, using a combination of air interface improvements as well as multi- carrier HSPA and MIMO. Technically though, MIMO and DC- HSPA can be used without the . E has an increased voice capacity (in excess of three times) compared to Rev. B offers downstream peak rates of 1. Mbit/s while Rev. C enhanced existing and new terminal user experience. While DECT cordless phones and Mobile Wi. MAX standards formally also fulfill the IMT- 2. Break- up of 3. G systems. In 1. 99. 9, ITU approved five radio interfaces for IMT- 2. ITU- R M. 1. 45. 7 Recommendation; Wi. MAX was added in 2. The cell phones utilise UMTS in combination with 2. G GSM standards and bandwidths, but do not support EDGE. The latter group is the UMTS family, which consists of standards developed for IMT- 2. DECT and Wi. MAX, which were included because they fit the IMT- 2. While EDGE fulfills the 3. G specifications, most GSM/UMTS phones report EDGE (. G specifications and standards were developed in fifteen years. The technical specifications were made available to the public under the name IMT- 2. The communication spectrum between 4. MHz to 3 GHz was allocated for 3. G. Both the government and communication companies approved the 3. G standard. The first pre- commercial 3. G network was launched by NTT Do. Co. Mo in Japan in 1. It was first available in May 2. W- CDMA technology. The first commercial launch of 3. G was also by NTT Do. Co. Mo in Japan on 1 October 2. By May 2. 00. 2 the second South Korean 3. G network was by KT on EV- DO and thus the South Koreans were the first to see competition among 3. G operators. The first commercial United States 3. G network was by Monet Mobile Networks, on CDMA2. EV- DO technology, but this network provider later shut down operations. The second 3. G network operator in the USA was Verizon Wireless in July 2. CDMA2. 00. 0 1x EV- DO. AT& T Mobility is also a true 3. G UMTS network, having completed its upgrade of the 3. G network to HSUPA. The first pre- commercial demonstration network in the southern hemisphere was built in Adelaide, South Australia by m. Net Corporation in February 2. UMTS on 2,1. 00 MHz. This was a demonstration network for the 2. IT World Congress. The first commercial 3. G network was launched by Hutchison Telecommunications branded as Three or . However its 3. G was relatively slow to be adopted in Nepal. In some instances, 3. G networks do not use the same radio frequencies as 2. G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates. Other countries' delays were due to the expenses of upgrading transmission hardware, especially for UMTS, whose deployment required the replacement of most broadcast towers. Due to these issues and difficulties with deployment, many carriers were not able to or delayed acquisition of these updated capabilities. In December 2. 00. G networks were operating in 4. HSDPA networks were operating in 7. Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the USA, telecommunication companies use W- CDMA technology with the support of around 1. G mobile networks. Roll- out of 3. G networks was delayed in some countries by the enormous costs of additional spectrum licensing fees. The license fees in some European countries were particularly high, bolstered by government auctions of a limited number of licenses and sealed bid auctions, and initial excitement over 3. G's potential. This led to a telecoms crash that ran concurrently with similar crashes in the fibre- optic and dot. The 3. G standard is perhaps well known because of a massive expansion of the mobile communications market post- 2. G and advances of the consumer mobile phone. An especially notable development during this time is the smartphone (for example, the i. Phone, and the Android family), combining the abilities of a PDA with a mobile phone, leading to widespread demand for mobile internet connectivity. G has also introduced the term . This 2. 00 millionth is only 6. Other leading countries. About half the mobile- broadband subscriptions are for subscribers in developed nations, 9. Note however that there is a distinction between a phone with mobile- broadband connectivity and a smart phone with a large display and so on. In Japan, 3. G penetration was similar at about 8. It is believed that Nortel and Lucent have undisclosed patents essential to these standards. Thus users sold 3. G service may not be able to point to a standard and say that the rates it specifies are not being met. While stating in commentary that . By allowing the UE (User Equipment) to authenticate the network it is attaching to, the user can be sure the network is the intended one and not an impersonator. G networks use the KASUMIblock cipher instead of the older A5/1stream cipher. However, a number of serious weaknesses in the KASUMI cipher have been identified. Some of the applications are: Global Positioning System (GPS)Location- based services. Mobile TVTelemedicine. Video Conferencing. Video on demand. Evolution. These specifications already display features characteristic for IMT- Advanced (4. G), the successor of 3. G. However, falling short of the bandwidth requirements for 4. G (which is 1 Gbit/s for stationary and 1. Mbit/s for mobile operation), these standards are classified as 3. G or Pre- 4. G. 3. GPP plans to meet the 4. G goals with LTE Advanced, whereas Qualcomm has halted development of UMB in favour of the LTE family.
