Technology for wide-band 3 g

Third generation or 3 G Broadband, broadband is a technology that enables high-speed Internet access via mobile devices.

3 G broadband technology uses create different standards to voice high speed wireless technology and mobile data networks. Standards are two effective technology 3 g Wideband Code Division multiple access (W-CDMA) and enhanced data GSM environment (EDGE GSM).

This operation

Used according to the provider of services 3 g technology GSM or CDMA broadband for transferring data.

CDMA-3 G broadband technology called evolution data optimized (EV-). EV - runs exclusively dedicated to a part of a mobile network data. As more bandwidth sound is still required calls, the separation of string voice data channel increases efficiency. 3 G is mobile broadband for high speed packet access (HSDPA) called down. In contrast to EV - DO, HSDPA can manage, voice and data transfers very effectively to a channel, so that 3 g mobile phone users speak and surf the Internet at the same time.

Speed

Offer 3 g broadband connections up to 14.4 Mbps per second speed download and 5.8 MB / S download speed.

Overall speed under each subscription vary software, provided by the Internet (ISP), the networking use service providers. Because 3 G used deliver broadband 3 g signals, data with the PSI, the speed will reduce more widely a user comes from a signal Tower 3. other factors include the lVelocity weather, traffic network and interference from other electronic devices.

Devices

3 G can access to any device with 3 g broadband technology.

While theCell phones widely used are 3 g broadband technology use, small devices to known the 3 g dongles access used broadband be. Cables are for use with desktop and portable computer via USB connected designed. Other devices that can access 3 G Broadband include computer smartphones, portable, PC cards.

Cost

A connection fee varies depending on each subscription package high-speed 3 g.

High packages, with upload and download speeds are usually very expensive. Unlike other types of connections band, DSL (digital subscriber line) and cable, 3 g broadband packages have a data plan and crossing borders specified data in the plan leads to pay user fees. By 2010, the cost of a package subscription with a plan data 5 gigabyte costs about 15 to $20.

Next generation

Fourth-generation wide-band or broadband 4 g succeeded in 3 G Broadband in March 2009.

The latter is improved versions of WiMax (worldwide interoperability for microwave access) and LTE (long term evolution) used to transfer data. 4 G a WAN or wide area network standards, meaning that it provides connectivity with devices over a large area as a city or even an entire country. Because most 4 G Broadband still istrelativ new 3 g broadband is type of technology used for mobile broadband by 2010.
