This work studies frequency allocation in 802.11s mesh wireless networks, employing muti-radio terminals and directive antennas. The network targets city-wide deployment and connects critical water tanks, storage reservoirs and pumping stations. The objective is to offer frequency planning with minimum remaining interference between the network terminals, under stringent and practical constraints, including a) long distances, on the order of 4--5 kilometers, b) radio terminals with broad beamwidths that serve multiple destinations, c) need for different frequency channels among different radio interfaces at the same terminal and d) limited number of frequency channels and transmission power. Practical centralized algorithms are provided for connectivity, conflict graph and frequency channel assignment, considering all constraints. It is shown that frequency planning under such stringent constraints is feasible.
