I've always been wondering, what 3G technology is all about. Prime Minister Manmohan Singh had first launched the 3G service in Delhi with MTNL.We also have so many mobile phone's with 3G technology, but still many of us do not know what is 3G Technology.
What is 3G?
3G is the next generation of wireless network technology that provides high speed bandwidth (high data transfer rates) to handheld devices. The high data transfer rates will allow 3G networks to offer multimedia services combining voice and data.
Additional features also include HSPA(High-Speed packet Access) data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.
3G wireless networks have the bandwidth to provide converged voice and data services. 3G services will seamlessly combine superior voice quality telephony, high-speed mobile IP services, information technology, rich media, and offer diverse content.
What are the Advantages of 3G?
3G networks offer users advantages such as:
New radio spectrum to relieve overcrowding in existing systems.· More bandwidth, security, and reliability.
Interoperability between service providers.
Fixed and variable data rates.
Always-online devices. 3G will use IP connectivity, IP is packet based (not circuit based).
Rich multimedia services.
What are Some Disadvantages of 3G?
There are some issues in deploying 3G:
The cost of upgrading base stations and cellular infrastructure to 3G is very high.
Requires different handsets and there is the issue of handset availability.
Base stations need to be closer to each other (more cost).
Tremendous spectrum-license costs, network deployment costs, handset subsidies to subscribers, etc.
These are just few information about 3G service, but actually speaking there's a hell lot of things that we need to learn about. Just search through google, you will get millions of website's telling you what is 3G service actually means. I also read that BSNL is planing to launch 3G, hope its been launched all over India.
