As the name suggests, 4G is the most recent (fourth) version of wireless communications standards. There’s less than 30 years of gap between the first-generation, huge, voice-only cordless cellular phones and high-speed, multifunctional smart cell phones of today. However,4G technology is not simply restricted to mobile phones. Constant developments in laptops, gaming gadgets, video cameras, and even refrigerators and vending machines will let them gain from 4G technology.
4G Connectivity –The background
The very first digitally encrypted mobile phones became available in the market in 1991 (Finland). A more advanced voice technology; second-generation cell phones could relay and receive data, for example text messages. The third generation of mobile communications entered the market from 2000 onwards. Mobile online access and video conferences came into effect, trailed by mobile broadband facility to laptops and latest version of mobile phones. The fourth generation mobile technology is all set to provide speedy data transfers in both stationary and mobile situations.
Purpose of 4G mobile technology
The purpose of 4G networking include providing quick, streaming, necessary multimedia services, integrated video calling, full voice-over-Internet protocol, and better international roaming, from both mobile and static positions. This new version treats all services as data packets and uses a different, advanced wireless range than third-generation gadgets. Since no single radio communication technology can offer high-speed data transmission and the high degree of mobility necessitated by the standards, access to the mobile services and mobile technology can no further be handled by a single provider.
In the month of October 2010, the ITU Radiocommunication Sector circulated its particulars for 4G services. The aim is to provide high-speed data transfer of up to 100 megabits per second when the user is in motion and a speed of up to 1 gigabyte per second when static. Popular as IMT-Advanced or International Mobile Telecommunications Advanced, the cellular plan should also supply scalable bandwidths of at least 40 megahertz.
