Fourth generation (4G) mobile systems are characterized by high data transmission rates between 20 to 100 Mbps, allowing for high-resolution video and TV. 4G networks use orthogonal frequency-division multiplexing and aim to complement existing 3G networks by providing high-speed downlinks. 4G technologies will converge fixed and mobile networks using all-IP architecture and enable nearly limitless applications like virtual workspaces, remote education, and multimedia.
