3G is the third generation of wireless mobile telecommunications technology. It is the upgrade to 2G, 2.5G, GPRS and 2.75G Enhanced Data Rates for GSM Evolution networks, offering faster data transfer, and better voice quality. [ 1] This network was superseded by 4G, and later by 5G. This network is based on a set of standards used for mobile ...
3G adoption. 3G mobile telephony was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates. Other delays were due to the expenses of ...

Initially constructed by China Unicom, sold to China Telecom in 2008. Gradual network shut down since Jun 2020. Network to shut down in 2025. CDMA2000 1xRTT, EV-DO Rev. Network to shut down ...
AT&T is scheduled to be the first carrier to shut down its 3G network on Feb. 22. T-Mobile will shut down its 3G network by summer and Verizon in December. The home-alarm industry has asked the ...
2G. 2G is a short notation for second-generation cellular network, a group of technology standards employed for cellular networks. 2G was commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa Oyj) in 1991. [ 1] After 2G was launched, the previous mobile wireless network systems were retroactively dubbed 1G.
The UMTS frequency bands are radio frequencies used by third generation (3G) wireless Universal Mobile Telecommunications System networks. They were allocated by delegates to the World Administrative Radio Conference (WARC-92) held in Málaga-Torremolinos, Spain between 3 February 1992 and 3 March 1992. [ 1]
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
The initial network activation was delayed due to unforeseen circumstances related to government agencies vacating the allocated spectrum. Despite launching the first 3G phone in November 2007, [58] the network itself wasn't operational until May 2008 in New York City. [59] [60] By 2009, T-Mobile had expanded its 3G network to cover over 200 ...
