Learning Outcomes
This course will examine technologies underlying current and future wireless communications systems. The unique challenges and opportunities that arise when using wireless connections will be explored in detai. An in-depth study of the physical layer and an understanding of the trade-offs to be made therein will be delivered. Following on from this, higher-layer techniques for establishing wireless physical links will be studied.
Medium Access Control (MAC), and network routing will be covered, with the emphasis on reducing access delay and increasing throughput. Case studies will be presented on wireless LANs, while coursework will look at cellular systems.
On completion of the course, the student is expected to:
1. Explain the concepts of radio transmission to the extent that they impact on wireless communications system design.
2. Explain and contrast different types of multiple access techniques, including TDMA, FDMA, CDMA and Carrier Sense.
3. Demonstrate an understanding of ad-hoc and infrastructure-less networks: in particular their organisation, MAC layer specifications and energy conservation techniques.
4. Discuss the basic concepts of mobility and radio resource management in
wireless networks
5. Discuss the principles of network discovery and routing in ad-hoc wireless networks
