Long Term Evolution (LTE) is a radio technology based on OFDM and MIMO technologies. LTE provides much higher data rates (over 100 Mbps) to users while reducing the cost-per-bit for service providers. This is very exciting to wireless operators who are eager to deploy multimedia rich Internet content over a wireless medium with seamless access anywhere at any time. This course describes the simplified architecture of LTE and moves on to OFDM and MIMO. The course also covers the downlink and uplink frame structure, OFDM operations at the physical layer, and resource management and scheduling considerations at the MAC layer. It steps through system acquisition, call setup, traffic operations and handover. The deployment and interworking issues with 2G/3G wireless networks are also explored. In summary, this course provides a comprehensive overview of LTE technology.
