The following is a list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. This list does not aim to cover all networks, but instead focuses on networks deployed on frequencies other than 2100 MHz which is commonly deployed around the globe and on Multiband deployments.
All of the major carriers plan on shutting down their 3G networks in 2022, with AT&T in February, T-Mobile in the summer and Verizon at year's end.
In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the US, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.
By May 2002, the second South Korean 3G network was by KT on EV-DO and thus the South Koreans were the first to see competition among 3G operators. The first commercial United States 3G network was by Monet Mobile Networks, on CDMA2000 1x EV-DO technology, but the network provider later shut down operations. The second 3G network operator in ...

There is a series of related technologies that were developed based on CGI that enhances the location precision: Cell Global Identity with Timing Advance (CGI+TA), Enhanced CGI (E-CGI), Cell ID for WCDMA, Uplink Time Difference Of Arrival (U-TDOA) and Any Time Interrogation (ATI), and the high accuracy terminal based method Assisted Global ...
Wireless tracker Milan Milanovic has discovered that the carrier is now using LTE data in Cleveland and Manhattan on 1,900MHz frequencies that were previously reserved for EV-DO (3G) service.
HSDPA is also known as 3.5G and 3G+. It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity. HSDPA also decreases latency, and therefore the round-trip time for applications. HSDPA was introduced in 3GPP Release 5. It was accompanied by an improvement to the uplink that provided ...
