Wireless and Mobile Networking, I
The course provides an overview of mobile and wireless networking with multimedia services, including voice and data. Fundamental concepts in designing mobile wireless systems are presented: frequency reuse, propagation and fading, interference, basic digital modulation and detection, channel capacity and coding/decoding, diversity gains (spatial, frequency, time), Medium-Access Control (MAC) protocols (TDMA, FDMA, CDMA, ALOHA-based), channel assignment methods (fixed versus dynamic), power control, handoff, scheduling methods for wireless packet networks. Examples of second generation (2G) circuits switched systems and standards and their evolution to third generation (3G) packet-based networks. If time permits, additional topics may be covered based on the class interest, e.g., issues in ad-hoc and sensor networks.
