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. The access points communicate in a frequency channel alternately selected from one of two disjoint sets and a first wireless modem (111) is constrained to communicate using a frequency channel from the first set and a second wireless modem (701) is constrained to communicate using a frequency channel from the first set. A data session controller (705) communicates data of the data session over links provided by the first wireless modem and the second wireless modem.
