OVERVIEW OF EXPLOINTING 3G
3G network has a greater network capacity through improved efficiency. So these technologies enable network operators to offer a wider ranges and advanced services. Services include wide-area wireless voice telephony and broadband wireless data, all in a mobile environment. Typically, they provide service at 5 to 10 Mb per second.
3G network works as same as IEEE 802.11 networks, it is wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony, While IEEE 802.11 (common names Wi-Fi or WLAN) networks are short range, high-bandwidth networks developed for data transmission.
The first pre-commercial 3G network was launched by NTT DoCoMo in Japan branded FOMA, in May of 2001 on the W-CDMA technology. The second network to go commercially live was by SK Telecom in South Korea on the CDMA2000 1xEV-DO technology.
The first European pre-commercial network was at the Island of Man by Manx, the operator owned by the British Telecoms group, and the first commercial network in Europe was opened for business by Telenor in December 2001 with no commercial handsets and thus no paying customers. These were both on the W-CDMA technology.
The first commercial United States 3G network was by Monet, on CDMA2000 1x EV-DO technology, but this network provider later shut down operations.
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. In Asia, Europe, Canada and the USA, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.
In many countries, 3G networks do not use the same radio frequencies as 2G, so mobile operators must build entirely new networks and license entirely new frequencies; an exception is the United States where carriers operate 3G service in the same frequencies as...
