Good Information about 3G

What about 3G?

Mobile services were originally offered by analog technology, radio, and they held the first-generation systems 1G. Subscribe to 2G straight ahead, as the analogue radio networks has been replaced by digital 2G networks) in 1990. Cell phones and mobile devices with 3G, send and receive data much faster than the second generation 2G systems that allow many more features and applications are possible. Increased, such as multimedia messaging, high-speed mobile broadband Internet connection the ability to see the video clip on your mobile phone.
A 3G phone and use the 3G network, you can make video calls, watch television, broadband Internet, receive e-mails and download music tracks, as well as normal voice calls and messaging services for mobile phones.
Technically, 3G is a generic term that covers a variety of wireless standards and technologies, including;
* CDMA -- Wideband Code Division Multiple-Access * CDMA2000 -- Code Division Multiple Access * UMTS-- Universal Mobile Telecommunications System * EDGE -- Enhanced Data for Global Evolution * HSPA - High Speed Packet Access, including HSDPA & HSUPA
Although developed for 2G digital version of the 1G analogue radio network, the emphasis is on calls. However, in the request to connect to the Internet to go, this Wi-Max, Wi-Fi, 2G, etc is part of Internet data services. But his average speed between the data rate of 56 kbit - s and 160 kb - s, which do not serve the real purpose of the Internet. Having in mind that this is a 3G technology and is a self-directed high bandwidth data transfer. Therefore, the concept of a faster wireless connection to reality.

How 3G working?

3G, or third-generation networks is different for 2G networks. If the invitation to the 2G line will remain open to debate, to consumers throughout the interview. 3G networks are sent via the data is divided into small "data packets" which are again in the correct order of beneficiaries. This means smarter encoding information can be transmitted and carried out effectively. In addition, the 3G phone is connected to more than one base station at a time and offers better performance and sound quality and speed of data transfer. 3G is also known as "mobile broadband", because the development is similar to the difference between a dial-up Internet and broadband services are always available. These are some of the services could be offered to 3G * Mobile Internet * Voice and video calls * Mobile TV * The mapping and GPS applications * Mobile e-mail

Why we need to use 3G?

The first thing you need is a single device (eg mobile phone), which is compatible with 3G. This is where the name comes from a 3G phone - the phone with the 3G functionality. Nothing to do with the cameras or the amount of memory. 3G phones are often two cameras, as the technology allows users to have video calls to consumers before the camera needed to capture the image from the front. You must join the service to the 3G network. We often call this kind of service, or data tariff plan. The device connects to the network for 3G mobile phone SIM cards () or 3G data card (which may be different: USB, PCMCIA, etc.) that are usually offered, sold the service provider. Despite the fact that when you connect to the Internet, if you have a 3G network.
