This module introduces the principles of communications networks, protocols and security mechanisms.
The major mobile and wireless communications are covered, including cellular communications and popular wireless networks including wireless local area networks (WiFi), wireless personal area networks (ZigBee), and low power wide area networks (LoRa/LoRaWAN).
Students are provided with basic concepts about network architectures, the implementation of different protocol stack layers, the major techniques used at each communications layer, the security mechanisms adopted to protect wireless transmissions.
