4G mean? It is not faster than 3G? Its rates are cheaper than ever and not 3G, users are “test” this technology?
1. 4G mean?
As well as the terms 2G or 3G, 4G is an acronym of the phrase “fourth generation” (4th generation) to facilitate the marketing program of the network.
Telecommunications service or wireless connection to use this technology is actually very different and depend on service providers but generally, a wireless 4G technology will be faster network 3G from 4 to 10 times.
2. 4G technologies that use?
World standards exist two core technologies of 4G is WiMAX and Long Term Evolution (LTE). WiMAX is a wireless standard developed by IEEE (Institute of Electrical and Electronics Engineers) and the 3GPP LTE standard, part of a coalition of home networks using GSM technology.
LTE and WiMAX both use the advanced receiver technology to improve the recording and operation of devices and networks. However, each technology will use a different band.
3. Compared to the speed of 3G 4G How?
Service providers to use WiMAX technology often have their ad network download speed (download) from 2 Mbps to 6 Mbps and peak as possible up to 10 Mbps or higher bit further. Verizon, the network is preparing to deploy LTE networks in the U.S. later this year, said their services would have a rate of about 5-12 Mbps.
Most 3G networks are currently at speeds from 400 kilobits per second for up to 1.5 Mbps.
4. Why do I need to 4G?
4G networks with higher speed will enable the speed of data transmission over the network is significantly improved and offer advanced services such as the use of mobile applications, on live video over the network, videoconferencing or online gaming will boom … really.
However, at “dangerous” as it’s 4G network can perfectly replace the fixed line internet (including fiber optic lines) not inferior speeds, wider coverage and mobility is very high.
5. Currently there is not 4G?
The answer is “Yes” but only in a certain place.
In America, the network partnered with Clearwire Sprint Nextel to offer 4G services based on WiMAX in 28 cities. In 2010, the alliance also plans to develop its services to cities like Los Angeles, New York, and San Francisco …
With LTE technology, Verizon is the network “enthusiasm” in the U.S. and most have formal plans to offer commercial 4G service in 25 to 30 major U.S. markets by the end of 2010. AT & T also plans to deploy LTE networks by 2011.
On international markets, WiMAX-based services are deployed in several countries such as Japan, Korea or Russia and only a single network deployment of LTE in Sweden.
