Radio over Fiber for Broadband Wireless Access

Fiber based wireless access systems support high-speed multimedia in real-time by combining the capacity of optical fiber with the flexibility of wireless networks. For example, single subcarrier multiplexed radio-over-fiber (ROF) link can support wireless LAN, cellular radio, and CATV simultaneously. We investigate various issues in this scenario in order to provide a cost-effective, high perf...

Reconfigurable medium access control protocols for wireless networks

Wireless networks are becoming ubiquitous. They have numerous applications also outside the cellular systems, for example in agriculture, multi-user games, healthmonitoring using body area networks, and security surveillance. Wireless networks operate using a limited and unstable radio resource, yet they must provide a reliable service for an array of varying applications and mobility patterns....
