3G Technology Introduction

The 3G services in mobile phones have been unveiled by different handset makers and cellular providers, although the corporations, generally aren't too good at telling the exact details, aside from a small number. There seems to be some sort of missing link in the present standard from the previous services by 2.5G of2G tech. Knowing the types and the details will aid you to pick the proper tools such as mobile broadband for your personal use or your occupation.

About 3G

3G cellular technology is categorized as the availability of wireless broadband data and information facilities right to a person's mobile phone. In comparison to the previous techs, 3G promises speeds that range all the way from 144 Kbps, which is three times as fast compared to the standard 56K dial-up modem connection of up to 2.4 Mbps, which is quite close cable-modem speed. The networks of 3G permit you to browse web sites rapidly, watch video broadcasts, download and listen to songs, videos and Three Dimensional games, view streaming videos as well as music clips and have a video conference with others anyplace around the globe.

New Developments

The HSDPA is a new technology, that may also be known as 3.5G, is coming very soon which offers quicker speeds of about 7.2 Mbps and also promises speeds of 14.4 Mbps in the near future. The interface is very much different for a cell phone, but other experiences such as downloading, real-time, browsing the net and sending messages and email may be just like a broadband Internet connection.

The Accesses

Currently, 3G tech is the more recent in mobile communications and is the abbreviation for third generation, making the analogue cell tech generation one, and digital/PCS generation two. The 3G tech is intended and made for the real multimedia cell device, also called smartphones. These tools provide greater bandwidths as well as transfer rates to serve web-based applications as well as local video in addition to audio data files.

The Networks

3G networks have the capability of transferring speeds of up to 2.4 megabytes per second being equivalent to around 15 seconds for every download of a 3-minute MP3 track. To do a comparison, the fastest 2G cell phones can transmit speeds of up to 144 Kilobytes per second, being equal to about eight minutes to download a 3-minute MP3 song.The high data rates of 3G are suggested while getting data on the Internet, in addition to sending and receiving huge multimedia files.

3G phones are comparable to small laptops that are able to cater to several broadband apps such as web browsing, getting real-time videos on the Internet, video conferencing and working with faxes.

What is broadband?

Broadband is one of those Internet terms that has several meanings, depending on the context. Probably the most popular understanding of broadband has to do with its formal title: broadband Internet access. Simply referred to as broadband, this is the high rate of data access to the Internet. This is opposed to dial-up access, or access via the telephone line, which is an older technology and limited to a 56kbps modem (only some 10% of Internet users in the United States are still using it). Broadband, on the other hand, usually means high-speed Internet, because its rate of data transmission is 256kbits. This bit rate is referred to as broadband throughout the world. As Internet use continues to expand, however, current broadband data rates will have to be expanded in order to meet the growing demand for video services, such as video conferencing, videophones and newsgroups. This means upgrading from the standard DSL (digital subscriber line) technology to very high speed DSL (VDSL) and fibre-optic connections, from the current much slower ADSL (asymmetric DSL) technology.

A more immediate challenge for broadband use is to provide service to customers on the rural periphery of large cities, whose high population density makes broadband technology profitable for providers. In some rural areas, satellite Internet access is an expensive broadband alternative. Third-generation cellphone networks are also capable of providing broadband Internet access. In addition, the term broadband is less popularly used to describe a range of frequencies used in telecommunications, data communications, communications over power lines, and cable television.
