Abstract: A relaying device, such as a router, especially those for forming the backbone of a wireless mesh network, comprises a first wireless frontend and a second wireless frontend which are to communicate with each other to facilitate data communication between a first external device and a second external device. The first wireless frontend is to communicate wirelessly with the first external device and the second wireless frontend is to communicate with the second external device using IEEE 802.11 infrastructure mode transmission protocol. Such a relaying device facilitates the cost effective construction of a high speed WMN of say 300 Mbps using infrastructure mode protocol contrary to conventional wisdom.

Abstract: A wireless mesh network comprises a first branch of access nodes and a second branch of access nodes. The first and second branches sharing a common access node and each access node is for facilitating wireless interconnection between a device and the network. The minimum separation distance (d1) between an access node in the first branch and an access node in the second branch is greater than K1/?d0, wherein d0 is the separation distance between a transmitting node and a receiving node in the first branch, K is the signal-to-interference ratio (SIR) and ? is the path loss exponential.
