4G in simple terms means a fourth-generation mobile technology, it is a name given to the advanced international mobile telecommunication standards defined by the ITU (International Telecommunication Union). What these standards mean are download speeds up to 1 gigabit per second while accessing wireless internet.
According to the ITU, 4G is the next-generation network that provides faster access, broadband multimedia services and unified messaging services.
Even if a user is mobile at a speed of 60 mph, 4G allows you to download speeds up to 100 MBS that translates by download of HD movies in less than 30 seconds!
It could be emphasized that there are different technologies that offer a broadband internet connection, while 4G would be different. For this reason, some technical standards have been specified by the ITU that should be followed by organizations that claim to offer 4G to its customers. The objectives and the defined standards are:
• An average data rate of 100 Mbit / s while users are physically moving at high speeds and 1gbit / s while users are relatively stationary.
• A minimum data rate 100Mbit per second between 2 points in the world.
• The flexible channel bandwidth of between 5 and 20 MHz and may optionally be up to 40 MHz.
• 1GBIT / s in the downlink must be possible on the bandwidth less than 67 MHz.
• Spectral efficiency of the system up to 3 bits / s / Hz / cell in the downlink and 2.25bit / s / Hz / cell for use inside.
• Seamless agreement on several networks.
• Smooth global roaming on heterogeneous networks and connectivity.
• High quality service for supporting the next generation multimedia (mobile television, HDTV video content, high speed data, etc.)
• Interoperability with existing wireless standards.
• A complete Internet protocol protocol, packet network.
It must be understood that the high speed of 4G or wireless has become inevitable and how it will change that the internet world can be judged of the last standard derived from the ITU; Data transfer via the Internet protocol.
Web 2.0 has brought a revolution and user-generated content is a significant portion of the Web. Social networking sites such as Facebook and Twitter have become cultural icons and shaped political movements. Other technologies such as IPTV have changed the television concept all together. The problem with such applications is networks as to date download speeds is a concern. This is where 4G technology between its extremely high speed, the 4G super fast could completely change the concept of these interactive applications.
Another area that will make a significant contribution via 4G networks would be cloud computing as increased mobility, speed and portability offered by 4G can be an important resource for these computer applications. As people spend less oriented capital expenditures (save online data instead of a hard disk), an increased data transfer rate will be essential for smooth operations and any delay will make cloud computing very unattractive. Cloud Computing thus transforms workstations from the size of mobile phones into powerful computers, but only if they are linked to a powerful network offering 4G download speeds and download speeds. This coupled with mobility makes the experience personal, portable and profitable.
It is said that IoT (Internet of Objects) is the next club to come. In future physical objects, even those we use for everyday life will be connected via a network. This technology is similar to today’s RFID cards. With so many 4G information flows will undoubtedly be part of such a revolution.
