Abstract: A method and device for wireless directional beam-forming transmission. The method for wireless directional beam-forming transmission between a first device and a second device comprises conducting one or more omni-directional transmissions between the first device and a third device; conducting one or more omni-directional transmissions between the second device and the third device; and determining directional information for directional beam forming transmissions between the first and second devices based on the omni-directional transmissions.

Abstract: A multiple wireless networks structure comprising a plurality of beacon groups each comprising one or more devices communicating via an associated wireless network utilising a superframe structure; wherein each device of each beacon group allocates a local control period and one or more neighbor control periods in each superframe; wherein the neighbor control periods in each beacon group cover all one or more control periods of other beacon groups detected by one or more of the devices in said each beacon group to an extent as said control periods do not overlap with the local control period in said each beacon group.
