A cellular communications system is provided have both satellite nodes and surface nodes for providing mobile cellular communications services for a plurality of mobile user units. The surface and satellite nodes are fully integrated by a network controller for providing service over large areas. In the alternative, each user unit includes link control means permitting the user unit to designate the mode of communications, either satellite node communications or ground node communications. In addition, multiple beam, relatively high gain antennas are disposed in the satellite nodes to establish satellite cells having enough gain in the satellite part of the system such that a user unit need only comprise a small, mobile handset with a non-directional antenna for communications with both ground nodes and satellite nodes.
