UMT LTE represents a major evolutionary step for GSM/UMTS networks. It is evolutionary as well as revolutionary, in the sense that LTE is non-disruptive, and allows seamless integration and backward compatibility with GSM/UMTS networks, and in the adoption of new techniques such as OFDMA, MIMO and an all IP network. This course contains a rich mix of technologies and guides the participants on the key technological enhancements of LTE, business and market considerations and drivers, with an emphasis on the ‘nuts’ and ‘bolts’ of LTE air interface, framing and channels, QoS, and signaling scenarios.
