The Technology Behind 3G and 4G
The third generation of standards of accessibility and speed for mobile devices is often referred to as 3G technology. These standards are set by the International Telecommunications Union (ITU). 3G technology enables wireless telephone usage over a wide area, as well as broadband internet access and video calls, all accessible by mobile electronic devices. 3G not only enables these services to be used over a wide area, but promises increased speed and bandwidth as well. Devices which use 3G are able to be used in most worldwide locations, due to intentionally engineered compatibility in the system. Although convenience and speed are enhanced with 3G technology as compared to other systems, speed depends greatly on the movement of the target device, such as a mobile phone , for example. 3G standards provide for data transfer rates of up to two megabits per second when a device is stationary or indoors, but this speed goes down to 384 kilobits at pedestrian speeds on the stree...
