Wireless mesh networks comprise nodes with multiple radio interfaces, and can provide low-cost high-speed Internet access or connectivity for data transfer. In this paper the authors report their experiences and investigations with an experimental metropolitan multi-radio mesh network that covers an area of approximately 60 km2 in the city of Heraklion, Crete. They present the design and deployment of the network, experiments to quantify the network's performance, and an application that runs on top of it and exploits its low-cost wide-area connectivity. The metropolitan network consists of 16 nodes, among which six are core nodes, each with up to four 802.11a wireless interfaces and an additional wireless interface for management and monitoring.
