What Is 4G
The most important technology for 4G is known as Open Wireless Architecture (OWA). It supports ultrahigh internet access, very high speed multimedia streams to the users. It can be used with any of the cell phones and any of the wireless devices. Many useful new options are available in the 4G networks. Access to the high definition videos (HD) is just a step ahead. In fact HD videos can also be downloaded as well as uploaded at the same time. It would make a great impact on the business world. There are thousands of conferences held every day around the world but it is very difficult for the individual to attend all the conferences. The concept of video conferences did came but it didn’t work provide an efficient result because of the slow streaming but this problem is overcome by the 4G networks.
A secure internet protocol (IP) solution is provided by it. Some of the objectives of the 4G networks are that between any two points in the world there must be a mobility rate of 100Mbps.The technologies that fall under 4G are Orthogonal Frequency Division Multiplexing (OFDM), Software Defined Radio (SDR) receivers, Orthogonal Frequency Division Multiple Access (OFDMA), Universal Mobile Telecommunications Systems (UMTS) and multiple input or multiple output technologies (MIMO).High rates for data transmission for 4G users are assured by these technologies. The huge demand of bandwidth did came because of the fact of downloading the information by the users is increasing rapidly every month from 10 to 20 to 30 gigabytes and so on. These would be provided by the 4G at a much faster rate. One Giga bytes per second (Gbps) transfer speed could be possible by the 4G networks. It had brought a new era to the download speed and would also lead to reduce the cost by the various telecoms. It would lead to higher end user phones, more powerful devices with more variety of applications to the users.
Concept of 4G
The concept of buffering won’t be there with the availability of 4G networks. It would also solve the problem of space. As a result of such extremely fast internet there won’t be a need to save any file other than that, they can just view it on the internet without buffering every time. There are millions of users on the social networking sites. Thus, sharing would be just a click away. It’s a gift to the gamers in order to play multiplayer games since most of the games involve high end graphics today. An extensive range of entertainment would be possible through it.
