3G Mobile phone technology explained
We are now going to tell you more about 3G technology…..Its still not available in India but it is going to come *soon*
3G is the 3rd Generation of GSM (Global System for Mobile communications) services.
The current generation of phones are mostly 2G (G is for generation, hence 2G is 2nd Generation). 2G allows for GPRS data transfer as well as voice. It is the most widely used radio technology for mobile communication.
While GPRS has data transfer speeds of max. 48kbps (using 10 data channels). Another Enhanced version of GPRS was also released and is known as EDGE (Enhanced Data Rates for GSM Evolution) which is sometimes also referred to as 2.5G.
Hence 3G is the advanced version and it allows speeds up to 384kbps. Its fast speeds also allows for video call facility (which is only possible if both the phones are capable of video calling).
UMTS has two operating frequencies:
First is the 2100MHz which is the more popular and second is 1900MHz which is used in the U.S. and some other areas.
In India, many operators plan to launch 3G services on the UMTS technology like Airtel, Vodafone and BSNL.
The major problem for implementation of UMTS is its spectrum (Radio Frequency band) usage which is more than the existing technologies and so its licensing has taken time and involves a lot of money too.
Expect it to come to India by May this year and the others who are using it in the other countries….Enjoy using it !!!!!
