In the world of technology, 4G continues to be a major buzzword in the community as more and more providers are looking to add this technology to their list of services. An acronym for fourth-generation wireless, 4G is a technology used with cell phones, wireless computers and other kinds of mobile devices, allowing faster Internet access than 3G networks are able to offer. It also permits the ability to access high-quality voice, high-definition video and better wireless channels using mobile devices.
Three years ago, the ITU Radio communication Sector defined 3G’s successor: It must provide a peak speed at 100 megabits per second for high users, including those in cars and trains, or 1 gigabit per second for pedestrians or those who are stationary. As with other generations, the new version wasn’t expected to be fully available for several years.
The 4G technology offers a wide range of services, including the ability to view, upload and download high-definition videos, which may change the way companies do business. For instance, it may be more likely to conduct video conferences. High-quality audio and voice is another benefit with 4G, which is also known as “beyond 3G” since it offers a secure IP solution.
Users can access high-quality streaming video and data “anytime, anywhere” faster than 3G was ever able to offer. This speed that 4G provides is often referred to as MAGIC: Mobile multimedia, Anytime, anywhere, Global mobility support, Integrated wireless solution and Customized personal services.
This technology has provided several objectives for its standard, which includes a rate of 100 Mbps between any two points in the world with high mobility as well as seamless connectivity so that users can roam across various networks while using high-quality multimedia. Many users are willing to upgrade as it is said to be about ten times faster than 3G.
The 4G technology will inter-operate with its predecessor and with broadband systems while also integrating with fixed wireless access, wireless local loop, personal area network and wireless local area network in an effort to make a wireless Internet fully based on IP. When it is completely implemented, 4G technology may create new markets and opportunities for those in the telecommunications industry. It can also potentially open the gates for mobile video blogging considering the technology combines cell phone use with advanced HD capabilities.
This new technology also places a focus on seamless service across various wireless networks with its broader bandwidth capability. Some core technologies that the 4G wireless uses include multiple input/multiple output, Universal Mobile Telecommunications System, Orthogonal Frequency Division Multiple Access, Software-Defined Radio and Orthogonal Frequency Division Multiplexing. Combined together, all of these technologies can guarantee that 4G users can easily get the promised rates of data transmissions, but it may not be widespread for several years.
