Abstract: A communication system comprises an access point communicating via a directional beam and a first and second wireless modem for establishing a first and respectively second mm wave radio communication link to the first access point. The first and second wireless modems are located on a vehicle and employ electronically steerable beamforming directional antennas having a first main beams for establishing the radio communication links A proximity detector detects proximity of the first wireless modem to the first access point. A switch controller switches data of a data flow from the first mm wave radio communication link to the second mm wave radio communication link in response to the detection of the proximity of the first wireless modem to the first access point.

Abstract: A method of maintaining data packet forwarding information in a first network node of a wireless mesh communications network having a plurality of network nodes interconnected by wireless communications links is disclosed. The method includes receiving respective activity indicators for neighbour network nodes connected with the first network node by respective wireless communications links, and determining respective link indicators for the outgoing wireless communications links of the first network node, each such link indicator being indicative of a data packet transmission characteristic for the link concerned. The method further includes, for each of the outgoing communications links of the first network node, combining the link indicator associated with that outgoing wireless communications link with the activity indicator relating to the neighbour network node connected with the first network node via that outgoing wireless communications link, thereby to generate a routing value for the outgoing wireless communications link for the destination network node. A selected next communications link for the destination network node is determined from the generated routing values; and is then stored as forwarding information relating to the selected next communications link for the destination network node concerned.

Abstract: A communication system comprises access points (203, 205) communicating via directional beams and a first and second wireless modem (111, 701) for establishing a first and respectively second mm wave radio communication links to access points (203, 205). The first and second wireless modems (111, 701) are located on a vehicle (103) and employ electronically steerable beamforming directional antennas having a first main beams for establishing the radio communication links. A common network element (705) supports communication over both links and a connection control circuit (1001) switches between the links. It further transmits an address resolution message over a link when switching to that link with the message comprising identification data for the common network element (705).

Abstract: A communication system supporting communication for nodes of a vehicle (103) comprises wireless access points (203, 205) for communication using directional beams. Wireless modems (701, 703, 111, 113) of the vehicle (103) establish a mm wave radio communication link to an access point (203). The vehicle network transmits link indications to at least one of the access points (203, 205) where a link indication provides a link between a MAC address of a wireless modem (701, 703, 111, 113) and a vehicle identity indication for the vehicle (103). An air interface scheduler (1001) for an access point (201) performs MAC layer scheduling over mm wave radio communication links established for the access point (201) in response to the first vehicle identity indication.
