Mobile and Wireless Systems

Subject description

Introduction to mobile communication systems (overview, concepts of wireless connectivity and mobility, a historical overview of commercial mobile systems, development guidelines). Electromagnetic wave propagation specific to mobile services (propagation modes, propagation under conditions specific to mobile services (N- LOS), fading, empirical propagation models, planning coverage). Cellular systems (network capacity, spectral reuse, call handover, interference in cellular systems, planning, methods to improve capacity and reduce interference). Digital mobile communications (digital data communication, modulation for mobile services, BER, channel coding). Channel access methods for shared medium resources (TDMA, FDMA, CDMA, SDMA, hybrid systems, network capacity and trunking). Architecture of wireless mobile systems and standardization (GSM, 3GPP, UMTS, WCDMA, LTE, LTE Advanced, development guidelines, WiFi, WiMAX, service carriers, signalling protocols, service architecture). Mobile services (voice, messaging, data communication, service convergence, All-IP networks, IMS).
