3G SUM DETAILS ABT IT

3G is the third generation of mobile phone standards and technology, superseding 2.5G. It is based on the International Telecommunication Union (ITU) family of standards under the IMT-2000.
3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. Additional features also include HSPA data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.
Unlike IEEE 802.11 (common names Wi-Fi or WLAN) networks, 3G networks are wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data.

SECURITY ISSUE WITH 3G

3G networks offer a greater degree of security than 2G predecessors. By allowing the UE to authenticate the network it is attaching to, the user can be sure the network is the intended one and not an impersonator. 3G networks use the KASUMI block crypto instead of the older A5/1 stream cipher. However, a number of serious weaknesses in the KASUMI cipher have been identified.
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.

ISSUES WITH 3G BETWEEN 3G PROVIDER AND USER
Although 3G was successfully introduced to users across the world, some issues are debated by 3G providers and users:
1.Expensive input fees for the 3G service licenses
2.Numerous differences in the licensing terms
3.Large amount of debt currently sustained by many telecommunication companies, which 4.makes it a challenge to build the necessary infrastructure for 3G
4.Lack of member state support for financially troubled operators
5.Expense of 3G phones
6.Lack of buy-in by 2G mobile users for the new 3G wireless services
7.Lack of coverage, because it is still a new service
8.High prices of 3G mobile services in some countries, including Internet access .
9.Current lack of user need for 3G voice and data services in a hand-held device
10.High power usage
