Enrich Life Through Communication
What is 3G?
3G3G is an ITU specification for the third generation (analog cellular was the first generation, digital PCS the second) of mobile communications technology. 3G promises increased bandwidth, up to 384 Kbps when a device is stationary or moving at pedestrian speed, 128 Kbps in a car, and 2 Mbps in fixed applications. 3G will work over wireless air interfaces such as GSM, TDMA, and CDMA. The new EDGE air interface has been developed specifically to meet the bandwidth needs of 3G.

Frequency of 3G
IMT ( International Mobile Telecommunication) suggest:
Standard Frequency:The bands 1 885-2 025 MHz and 2 110-2 200 MHz are intended for use, on a worldwide basis.
For FDD mode: 1920 - 1980 MHz and 2110 - 2170 MHzFor TDD mode: 1885 - 1920 MHz and 2010 - 2025 MHz
Another 160 MHz of additional spectrum should be available in its entirety prior to 2010.The frequency bands 698 to 806 MHz, 2500 to 2690 MHz and 2700 to 2900 MHzshould be non-exclusively designated for the use of IMT-2000 to provide from 2005 for up to an additional 160 MHz of spectrum for IMT-2000.
