A method for controlling communication between a hub and a plurality of distributed stations over a medium is disclosed. The method comprising the steps of a method for controlling communications access between a hub () and a plurality of distributed stations (M-M) over a medium, the method comprising the steps of (a) allocating a plurality of channels for data communications between the station (M-M) and the hub (), the number of channels being at least equal to the number of stations, (M-M) and each station owning at cast one channel, each channel being varyingly in one of an empty-, a reserved, or an owner-state, and whereby (i) the empty-state provides a channel to which any station (M-M) can have access; (ii) the reserved-state provides a channel to which a station (M-M) having made a reservation with the hub (), but not owning the channel, can have access; and (iii) the owner-state provides a channel to which only the owning station (M-M) has access; and (b) allocating the respective state and/or the number of channels over time an the basis of each station's data requirements.

Medium access control protocol for data communications

The present invention discloses a wireless LAN, a peer-to-peer wireless LAN, a wireless transceiver and a method of transmitting data, all of which are capable of operating at frequencies in excess of 10 GHz and in multipath transmission environments. This is achieved by a combination of techniques which enable adequate performance in the presence of multipath transmission paths where the reciprocal of the information bit rate of the transmission is short relative to the time delay differences between significant ones of the multipath transmission paths. In the LANs the mobile transceivers are each connected to, and powered by, a corresponding portable electronic device with computational ability.
