CN 8817: Wireless Networks

NOTES | LABS | SOLUTIONS | FINAL GRADES

Objective:

This course gives an overview of wireless networking, which includes an introduction to wireless physical characteristics and mobility. It discusses signal propagation, wireless channel characteristics, and multiplexing techniques. It does not cover material on coding and modulation as they are covered in CN8811. It discusses cellular networks with the system-level details of GSM and GPRS. It also gives an overview of the architecture of 3G system – UMTS. It discusses the need for specialized MAC for wireless, and MAC protocols for 802.11, WiFi, and GPRS in detail. It covers IEEE 802.11 and WiMAX standards in sufficient detail. Mobility is an important characteristic of cellular and wireless LAN networks. The course describes Mobile IP. Future Architectures of multi-hop wireless networks, e.g. Mesh, Ad Hoc and Sensor Networks are also discussed.
