Before mentioning the best features of 3G, Let's discuss what is 3G basically ? 3G is part of a family of standards for mobile telecommunications developed by the International Mobile Telecommunications (IMT). The Standard is also known as 3rd Generation or IMT-2000. It differs from 1G and 2G phones in terms of higher data rates for voice and data and allowing simultaneous use of speech and data services.
The 3G Technology is divided into GSM and CDMA. It is often called 'Mobile Broadband' also as it can be carried anywhere. The use of 3G first started by Japan in 2001, when NTT DoCoMo and W-CDMA Technology sell their products for the first time on a limited basis, followed by SK Telecom of South Korea in 2002. In USA, 3G network was pioneered by Monet Mobile Networks with CDMA technology followed by Hutchinson Telecommunications of Austrilia in 2003 only. Till today 3G networks is operated in more than 50 countries and more than 200 million customers are connected through 3G networks.
Specifications of 3G
- Frequency Band : 1.8 - 2.5 GHz
- Bandwidth : 5 - 20 MHz
- Switching : Circuit/Packet
- Minimum Data rates : 200 Kbps to meet IMT-2000 Specification
- Standard Data rates : 384 Kbps (Kilo bit per sec) or more
- Maximum Data rates : Upto 2 Mbps
The 3G phone uses the method of 'Packet Switching' for data transmission. The data is split into packets each with unique address and can be sent on any path in a network. Again it is recombined and interconnected to retrieve the data at the destination, thus data will be received at a less time as compared to that of voice calls. As usual, voice calls are interpreted through Circuit Switching.
At present all the major 3G Networks are using FDD ( Frequency Division Duplex ) mode of operation. In the FDD mode of operation, the uplink and downlink use separate frequency bands. The lower frequency band is used for the Uplink transmission and he upper frequency band is used for the Downlink transmission.
For Consumers, 3G high end application will take Cellphone use to the next level.Customers will be able to avail Internet with entertainment together. I am listing few facilities of 3G services :
- High Speed Internet
- Video Streaming
- Video Calling
- Video Conferencing
- TV Viewing
- Online Movies
- Online Games
- Content Download
- Data Sharing & Transfer
- Multimedia Messing Service (MMS)
According to TRAI ( Telecom Regulatory Authority of India) , 150 million Cellphone users had already Subscribed and used Internet services by end of 2009 in India, so you can easily imagine the kind of demand in coming years. So big opportunity for Telecom operators to grab this opportunity.
It will be good for everybody, if competition amongst operators ensure affordability.
The next level of 3G Technology is 4G, which is expected to hit the World Telecom Sector in 2012. It will be superior than 3G in terms of speed and transfer of data. Data transfer rates will be up to 100 Mbps outdoor and 1Gbps indoor. So just wait and wait for the arrival of the this fantastic technology. Till then enjoy the ride of Mobile Broadband using 3G technology all the way on your 3G phone in coming days....!!
" HAPPY SURFING ! "
