4G – Fourth Generation of Mobile Communications

4G wireless network are aimed  to reduce cost, increase speed, flexibility and universal access. Increased speed is a critical requirement for 4G wireless services. Data-rate increases of 10-50X over 3G will put streaming audio and video access into the hands of consumers.  


They target to solve still-remaining problems of 3G (third generation) systems and to provide a wide variety of new services, from high-quality voice to high-definition video to high-data-rate wireless channels.  


The goal of 4G will be to replace the entire core of cellular networks with a single worldwide cellular network completely standardized based on the (Internet Protocol) IP for video, packet data utilizing Voice over IP (VoIP) and multimedia services. Networks would provide uniform video, voice, and data services to the cellular handset or handheld Internet appliance, based entirely on IP (Internet Protocol).

4G Technology is likely to support interactive services like

€¢ Interactive Multimedia, Voice, Video Streaming
€¢ High Speed Global Internet Access €“ VPN Availability
€¢ Service Portability with Scalable Mobile Services
€¢ High Speed, High Capacity, Low Cost Services
€¢ Improved Information Security
€¢ QoS Enhancements
€¢ Multi-Hop Networking
€¢ Spectral Bandwidth Efficiencies (8bits/Second/Hz)
€¢ Seamless Network of Multiple Protocols – 4G must be all-IP*
