It is the upgrade for 2. 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 1G systems were introduced in and the early to mids. Each generation is characterized by new frequency bands, higher data rates and non—backward-compatible transmission technology.
The first commercial 3G networks were introduced in Several telecommunications companies market wireless mobile Internet services as 3Gindicating that the advertised service is provided over a 3G wireless network. Services advertised as 3G are required to meet IMT technical standards, including standards for reliability and speed data transfer rates. The above systems and radio interfaces are based on spread spectrum radio transmission technology.
There are evolutionary standards EDGE and CDMA that are backward-compatible extensions to pre-existing 2G networks as well as revolutionary standards that require all-new network hardware and frequency allocations. The technical specifications were made available to the public under the name IMT Both the government and communication companies approved the 3G standard. The first commercial launch of 3G was also by NTT DoCoMo in Japan on 1 Octoberalthough it was initially somewhat limited in scope;   broader availability of the system was delayed by apparent concerns over its reliability.
The first pre-commercial demonstration network in the southern hemisphere was built in AdelaideSouth Australia by m. This was a demonstration network for the IT World Congress. The first commercial 3G network was launched by Hutchison Telecommunications branded as Three or "3" in June Emtel launched the first 3G network in Africa.
Japan was one of the first countries to adopt 3G, the reason being the process of 3G spectrum allocation, which in Japan was awarded without much upfront cost.
Frequency spectrum was allocated in the US and Europe based on auctioning, thereby requiring a huge initial investment for any company wishing to provide 3G services. European companies collectively paid over billion dollars in their spectrum auctions. Nepal Telecom adopted 3G Service for the first time in southern Asia.
However, its 3G was relatively slow to be adopted in Nepal. 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 countries' delays were due to the expenses of upgrading transmission hardware, especially for UMTSwhose 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.
Roll-out of 3G 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 auctionsand initial excitement over 3G's potential. This led to a telecoms crash that ran concurrently with similar crashes in the fibre-optic and dot.
The 3G standard is perhaps well known because of a massive expansion of the mobile communications market post-2G and advances of the consumer mobile phone. An especially notable development during this time is the smartphone for example, the iPhoneand the Android familycombining the abilities of a PDA with a mobile phone, leading to widespread demand for mobile internet connectivity.
By Junethe millionth 3G subscriber had been connected of which 10 million were in Nepal and 8.
This millionth is only 6. Other leading countries [ when? 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—although according  to the ITU and informatandm.
Even then, some patents essential to 3G might have not been declared by their patent holders.
It is believed that Nortel and Lucent have undisclosed patents essential to these standards. ITU has b [ vague ] definition of the data rate that users can expect from 3G equipment or providers.
Loburhanstandard and say that the rates it specifies are not being met. Compare data speeds with 3. 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. In addition to the 3G network infrastructure security, end-to-end security is offered when application frameworks such as IMS are accessed, although this is not strictly a 3G property.
The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users. On 14 DecemberTelia Sonera announced in an official press release that "We are very proud to be the first operator in the world to offer our customers 4G services.
