Prerequisite: Course ECS 252

Grading: Letter; one exam (40%), homework/reports on papers (30%), project (30%)

Catalog Description:
Fundamental techniques in design of second generation wireless networks: cellular network and protocols, medium access techniques, handoff control, signaling and mobility management, wireless data works, Internet mobility and Personal Communication Services (PCS). Third generation wideband systems, novel technologies, adhoc networks. Offered in alternate years.

While ECS 252 is the core graduate course in computer networks and deals with the fundamental principles of networking, ECS 257 is devoted to mobile and wireless networks, in particular, on the protocols and architectures of existing and emerging wireless networks. The course will develop the fundamental concepts in wireless networks; the different access technologies, handoff control and mobility management protocols, and existing and emerging applications. Through assignments, and projects, the students will learn the key design issues in wireless networks supporting traditional voice applications as well as Personal Communication Services (PCS) and new multimedia applications. This course will prepare the students to start research in the area of the mobile and wireless networks.
