They include the use of always-on data access, higher voice capacity, and high data speeds. The other higher end features are live, streaming video.

3G uses two different types of technology standards they are UMTS and CDMA. The technology in UMTS is based on WCDMA and it can be interchanged. The other one is CDMA2000 which is the latest version of CDMA 2G technology.

3G has many features like video streaming using GPRS or EDGE, the access is slow but it works. The other feature is the live video with which you can watch Cricket Matches. Video calling with an additional camera helps to talk with the other person face to face. There is facility to browse with faster downloads. It is also useful for those who want to do high speed browsing.

Some 3G mobiles have a shorter battery life. This hampers the high-speed data download functions, making it difficult for longer use. Check out the battery when buying a 3G mobile.

3G phones are for the present generation on the lookout for reliable, best technology

Now what is this GPRS? It stands for “General Packet Radio Service”. And as the name suggests, it is a service of transmission and sharing of data over the mobile phone services in the form of packets.
The best part of the GPRS technology against the traditional old-form circuit switching is that they are charged according to the amount of megabytes of data transferred in contrast with of the charging according to the amount of “on” time as followed by the circuit switching technology.
The “European Telecommunications Standard Institute” (ETSI) originally standardized the GPRS technology but now, it is taken over by the “3G Generation Partnership Project” (3GPP). It normally offers a moderate rate transfer of data through the using of the unused TDMA channels; TDMA stands for “time division multiple access”. It follows the GSM standards and was developed as a response to the earlier mobile communications technology like i-mode packet switching and CDPD, etc.
GPRS technology is one of the best packet switching data transferring technologies that has been developed in the recent times and it is one of the most popular of the mobile technologies of all time.
