Introduction to wireless communications: Evolution of mobile radio communications,
paging system, cordless telephone system, cellular telephone system, Modern
wireless communication systems: 2G networks, 3G networks, Bluetooth and
personal area networks.
Mobile radio propagation: large scale path loss - Free space propagation model,
basic propagation mechanisms. Digital Cellular Transmission, Spread Spectrum
Transmissions Local Area & Ad Hoc Networks: LAN Technologies: Evolution of Wireless LAN, IEEE802.11, Physical, Layer, MAC Sub-layer, routing algorithms.
Adhoc networks: Characteristics – Performance issues. Overview to Wireless
ATM, HYPERLAN, IEEE802.15 Wireless PAN, and Home RF.
