4G !
The technology called 4G has redefined the whole concept of today’s sophisticated communication. According to the Wireless World Research Forum (WWRF), 4G is a combination of wired and wireless networks in computer, consumer electronics and communication technology systems based on the internet technology, that can merge applications like the Wi-Fi and WiMAX capable of transmitting at a speed ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks).
This collection of technologies and protocols delivers high quality of service at both ends and high point security. Officially named by IEEE as Beyond 3G (B3G) it provides with the lowest cost wireless network.
4G is being developed to accommodate the quality of service (QoS) and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, HDTV content, Digital Video Broadcasting (DVB), minimal services like voice and data, and other streaming services for "anytime-anywhere"
