Abstract: Embodiments of the invention relate to low-cost and low-complexity mesh routing method to provide connectivity within a channel-diverse mesh network in which there is no common channel available for the whole network and in which a single transceiver is provided in each node. The mesh routing method includes a procedure for flooding radio resource maps (RRMs), a procedure for determining the operating channel for each mesh node device, a routing procedure for establishing a route for a pair of source device and destination device, and a maintenance procedure for repairing routes and optimize selection of operating channel.

Abstract: A low-profile wideband monopole antenna is provided. The antenna may include a radiating element configured in a bent monopole arrangement to provide a vertical polarization such that an omni-directional radiating characteristic is achieved. The radiating element may include a plurality of slots formed at or edged from each side of the radiating element to increase the effective current path length of the radiating element. The antenna may include a feed and a feeding structure extending from the radiating element to the feed. The antenna may further include a ground plane. The radiating element may be arranged substantially parallel to the ground plane. The surface area of the radiating element may be smaller than the ground plane.
