EP2950 Wireless Networks 7.5 credits

Wireless networks have revolutionized our ways of communicating, interacting, and working. They will continue to have huge impact in the future, in the Internet of Things era, where everything that can benefit from a communication network will be connected. This course discusses the fundamental issues of wireless networking, with examples from cellular, local area and sensor networks. The course focuses on use of mathematical modeling for network protocol design, providing the necessary theoretic tools for future studies and research in the area.

The course also explains and motivates the design of national and international standard solutions for mobile, local area and sensor networks.
