What is 4G technology?
4G technology is the fourth generation of wireless technology available from mobile service providers. This technology, sometimes also called the "Ultra Mobile Broadband", is designed to provide higher data transfer speeds and a safer connection. Various wireless devices can use 4G technology, including phones and tablets. However, there is some controversy about the use of "4G", because some of the first adoptors have not met the requirements of the technological standard.
Purpose 4G
Ultra Mobile Broadband concerns faster data transfer speeds available on the wireless network. 4G technology can provide data transfer speeds between 100 megabits per second (MBPS) and one gigabite per second (GBPS). For comparison, 3G or third generation networks offer data transfer speeds of about 200 kilobites per second (KBPS), which is significantly slower than the power that allows 4G technology.
4G network connections can also be a multiple accurator while traveling when they areLocation of the user and the tower at constant speed changes. For example, when a user travels in a car and transmits data signals between towers that 4G process more efficiently than previous technologies. This faster and more accurate connection can allow the transfer of larger data packets than 3G networks. Users have access to more and more information applications, such as high -resolution TV (HD) and real -time video chats.
devices using 4G
4G Wireless service can use modem, mobile phones and other devices such as laptop computers. Mobile hotspots offer wireless connections for multiple devices, including computers, tablets and handkerchiefs; With 4G technology, users can also download and use large applications on each device at the same time. 4G "Netbook" or tablet device could work similarly to noterite, but with smaller memory and mThe discs, offer immediate access to the Internet and web communication in real time.
Discussion of Standard
developers set certain standards for high-performance 4G technology capabilities in accordance with those dictated by the International Telecommunications Trade Union (ITU-R). While companies have not yet reached the 4G technology at the beginning of the 21st century, some began to use "4G" to describe their networks. This was initially cloudy, but eventually allowed if the technology used would probably prepare a path for real 4G performance. New systems such as Mobile Wimax and long-term evolution (LTE) were referred to as "4G", although they did not reach the performance of marked standards of ITU-R.
Development of wireless technologies
The first generation available wireless technology, 1G, refers to the analog signal used by the cellular towers in the 80's. 2G technology at the age of 90 has upgraded an analog signal to digital and allowed people to sendAT text messages across the network. 3G technology, at the beginning of 2000, used an electromagnetic wavelength to broadcast a wireless broadband signal that allows users to access the Internet and download applications using pocket mobile devices. The 4G technology further upgrades these networks with faster information transmission, increased security and greater information exchange capabilities.
