Abstract
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.
