ECE Department Seminar: Evolution to 4G Wireless - the dominant role of LTE
February 13, 2013
Dr. Vijay K. Varma,
Applied Communication Sciences
Red Bank, NJ
Time: 3:00 PM -- 4:00 PM, Feb 13th (Wednesday), 2013
Location: Babbio Center, Room 319
The trend towards All-IP networks and the increased demand for multimedia services prompted the wireless industry to adopt a packet based radio-access technology and an optimized packet core network. Evolved Packet System (EPS), an evolution to GSM and UMTS technologies - with an industry-adopted name of Long Term Evolution (LTE) – has become the most dominant technology in the race for 4G wireless.
This talk will address the evolution from GSM/UMTS technologies to 4G wireless dominated by the LTE. The talk will cover the drivers for 4G, the architectural details of LTE and the Evolved Packet Core (EPC), QoS support for real-time services, and seamless mobility within and across multiple radio access networks provided by LTE. This will be followed by a status of LTE deployments and projections worldwide, and brief preview of Voice over LTE (VoLTE) – a technology that will change the way telephone networks operated for over 100 years.
