Principles of wireless communications and how they differ from wired communications. Fundamental concepts including transmission and mitigation techniques (e.g., modulation and coding, propagation, interference, and antennas) for wireless systems, multiplexing techniques, wireless system architectures, mobility management, security, protocols, and location technology. Systems include cellular phone networks (e.g., cdma2000, UMTS), wireless local area networks (e.g., IEEE 802.11g), personal area networks (e.g., Bluetooth), fixed-point broadband wireless (e.g., WiMAX) and satellite systems.
