Early in 2012, The ITU formally approved IMT-Advanced 4G including "LTE-Advanced" and "WirelessMAN-Advanced" and Ericsson is the first to show LTE-Advanced test in mobile environments, to speeds up to 1Gbps, fold over 10 times the current speed in the commercial LTE network
Currently, 4G LTE is being implemented in Release 8 and now has 17 networks were commercially launched globally, providing services to about 200 million bao.Theo statistics of the Association of suppliers mobile terminal (GSA), as of January 2012, there were 285 mobile networks in 93 countries committed to deploying LTE. Today, the LTE network can provide speeds up to 100Mbps, but the speed changes depending on network load, destination and time of each network. There are about 100 kinds of LTE devices already on the market.

Mr. Hakan Ohlsen-Ericsson Chief Technology Asia - Pacific said
The standard approved by ITU 4G IMT-Advanced technology has created a global harmonization, meet the stringent requirements during operation. When deployed on a global scale or on the band area was agreed, would bring economic and reasonable price. Technology development based on agreed frequencies in the region and globally will ensure the system infrastructure brings uniformity to optimize the cost for the network and also provide equipment more affordable for consumers with a variety of choices to the voice device intelligent devices such as smart phones, tablet PCs and
According to the 4G network will be needed if Vietnam really need a huge capacity to meet actual needs.
Currently in Vietnam, 3G fully meet current needs and in a few years. It is difficult to say exactly in what should be 4G, but with the fact that mobile data traffic average annual 2-fold increase to 2016 and is expected to be 5 billion mobile broadband subscribers, the 4G will be a step forward The next development in the future and one of the basic conditions for implementing 4G successfully in a country that has frequency and equipment. And now, according to the GSA as of January / 2012, has 17 global LTE/4G network is deployed and a total of 285 commercial operators in 93 countries have committed to deploy LTE/4G.
