3G: High-Speed IP Data Networks

3G refers to an ITU specification for the 3rd generation of wireless mobile telecommunications technology.

3G mobile telecommunication was first introduced in May 2001 as a pre-release of W-CDMA technology. on 1 October 2001, the 3G network was launched commercially by NTT DoCoMo in Japan.

3G technology is the upgrade for 2.5G and 2.5G GPRS networks, and it promises increased bandwidth and faster data transfer speed.

3G networks work over wireless air interfaces such as GSM, CDMA, and TDMA as well as the EDGE air interface.

3G Network Features

– 3G Characteristic: Digital broadband, increased speed, fast communication, video calls.

– Frequency: 1.6 – 2.0 GHz

– Bandwidth: 100MHz

– Capacity (data rate): 144kbps – 2Mbps

– Technology: CDMA, UMTS, EDGE

What is the difference between 2G and 3G networks?

The main difference between 2G and 3G networks is that GSM (2G) can provide voice and video communication using GPRS, while 3G provides high-speed internet, high-speed video communication, video conferencing, etc.

The data transmission rate on a GSM (2G) network is 200-300 Kbps, while the downloading speed can go up to 42Mbps in 3G networks.

Overall, 3G networks are much better and work faster than the 2G network.
