4G Technology
[attachment=47830]
Why 4G?
• 3G may not be sufficient to meet needs of future high-performance applications like multi-media, full-motion video, wireless teleconferencing.
• Multiple standards for 3G make it difficult to roam and interoperate across networks
• Requirement of a single broadband network with high data rates which integrates wireless LANs, Bluetooth, cellular networks, etc
4G - Also known as "Beyond 3G", 4G refers to the fourth generation of wireless communications. The deployment of 4G networks should be in the 2010-2015 timeframe and will enable another leap in wireless data-rate and spectral efficiency. ITU has specified IMT-A (IMT-Advanced) for 4G standards.
4G is all about convergence; convergence of wired and wireless networks, wireless technologies including GSM, wireless LAN, and Bluetooth as well as computers, consumer electronics, communication technology and several others. 4G is a Mobile multimedia, anytime anywhere, Global mobility support, integrated wireless solution, and customized personal service network system
4G wireless technology is also referred to by “MAGIC” which stands for Mobile multimedia, Any-where, Global mobility solutions over, integrated wireless and Customized services.
4G is an all IP-based integrated system will be capable to provide 100 Mbps for high mobility and 1 Gbps for low mobility , with end-to-end QoS and high security, and will offering various services at any time as per user requirements, anywhere with seamless interoperability, at affordable cost. The user services include IP telephony, ultra-broadband Internet access, gaming services and High Definition Television (HDTV) streamed multimedia.
4G Requirements - As per ITU's IMT-A
• All-IP packet switched network.
• Data rates up to 100 Mbps for high mobility and up to 1 Gbps for low mobility.
• Seamless connectivity and global roaming
• Interoperability with existing wireless standards
• Smooth handovers.
• High QoS.
