3G networks were developed to address limitations of 2G networks like low data rates, voice-centric design, and incompatible global standards. 3G offers higher bandwidth through factors like chip rate and channel structure, enabling new applications for consumers like video streaming and location services, and for businesses like video conferencing and real-time financial information. The data speed of 3G depends on a combination of technical factors as well as the number of users and their distance from the cell tower.

1. Why move on to 3G Life?
Limitations of 2G
Voice centric
Designed mainly for telephony application
Circuit-switched
High BER (Bit Error Rate)
Low data bit rate (< 14.4kbps)
Too many standards globally
GSM, CDMA, PDC, PHS etc.
Isolated networks
MAP based
IS-41 based
Difficult to roam between these networks

2. How fast exactly is 3G
The data speed of 3G is determined based on a combination of
various factors including :
Chip rate
Channel structure
Power control
Number of users in a cell
Distance of user from cell
User is moving or stationary
Synchronization

3. Features of 3G Life
Higher bandwidth enables a range of new applications
For the consumer
Video streaming, TV broadcast
Video calls, video clips – news, music, sports
Enhanced gaming, chat, location services…
For business
High speed teleporting / VPN access
