A communication system comprises access points () communicating via directional beams and a first and second wireless modem () for establishing a first and respectively second mm wave radio communication links to access points (). 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 common network element () supports communication over both links and a connection control circuit () switches between the links while providing a single wired connection point. A multipath controller () communicates with a complementary multipath controller of the fixed network over a plurality of paths with the multipath controller () having a first wired port for a first path of the plurality of paths connected to the first single wired connection point.

Communication with vehicle based node

A communication system supports communication between an end node () of a vehicle () and a remote correspondent node () via a fixed network () which comprises a plurality of wireless access points () with a directional antenna arrangement for mm wave radio communication using directional beams. A vehicle () comprises wireless modems () employing electronically steerable beamforming directional antennas for establishing mm wave radio communication links to the access points (). At least one first access point () is arranged to transmit multipath environment data for an area supported by the access point to the wireless modems (). A controller () of the vehicle is arranged to set a diversity property for transmissions of data from the wireless modems to the wireless access points in response to the multipath environment data.

Wireless communication for vehicle based node

A communication system comprises access points () communicating via directional beams and a first and second wireless modem () for establishing a first and respectively second mm wave radio communication links to access points (). 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 common network element () supports communication over both links and a connection control circuit () 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 ().

Communication system supporting communication between end node of a vehicle and a remote correspondent node via a fixed network

A communication system comprises a fixed network comprising access points for mm wave radio communication using directional beams. A wireless modem of a vehicle comprises a first search circuit searching for a beacon transmission in a first frequency channel. A first data receiver extracts data from a detected beacon signal including: an indication of a first access point transmitting the beacon signal; a first load value indicative of a loading of the first access point; and an indication of a second access point having overlapping coverage with the first access point. Another receiver extracts data from a second beacon signal transmitted by the second access point in a second frequency channel including a second load value indicative of a loading of the second access point. A controller selects a target access point dependent on the first and second load values, and initializes a link setup with the target access point.

A vehicle () comprises wireless modems () employing electronically steerable beamforming directional antennas for establishing mm wave radio communication links to the access points (). The wireless modems () forms links to two different access points (). A ink manager () is arranged to terminate a second mm wave radio communication link in response to a link failure a first mm wave radio communication link, and to initialize setup of a third mm wave radio communication link in response to the termination of the second mm wave radio communication link.

A vehicle comprises wireless modems employing electronically steerable beamforming directional antennas for establishing mm wave radio communication links to the access points. At least one first access point is arranged to transmit atmospheric water content data for an area to the wireless modems. A link management controller of the vehicle is arranged to perform the link management in response to the atmospheric water content data. For example, mm wave radio communication links may be initialized or terminated based on the atmospheric water content data.
