Claim 0:
1. A radio communication system comprising a plurality of aerial nodes for providing a radio route via one or more of said aerial nodes for data transmissions between two ground-based nodes, each of said nodes including a plurality of directional antennas for transmitting and receiving radio signals in a plurality of different directions, wherein:
said nodes comprise a first node type for transmitting radio signals only in a first frequency band and simultaneously receiving radio signals only in a second frequency band different from said first frequency band, and a second node type for transmitting radio signals only in said second frequency band and simultaneously receiving radio signals only in said first frequency band;
said aerial nodes comprise a plurality of each of said first node type and said second node type and said ground-based nodes comprise a plurality of each of said first node type and said second node type;
each said ground-based node comprises a sending ground station for transmitting initial information signals including an address of said sending ground station simultaneously from a plurality of its directional antennas;
each said aerial node includes route creation circuitry for selecting a radio link between said aerial node and a sending ground station from which said aerial node received an initial information signal, and another radio link between said aerial node and another node based on a routing message said other node received from said aerial node including the address of a sending ground station;
each said ground-based node comprises a receiving node for receiving routing messages transmitted by said aerial nodes and an originating node for transmitting data to a destination ground station having the sending ground station address included in a routing message received from an aerial node;
said system further comprises at least one dual-type ground-based node comprising a first antenna set for transmitting radio signals only in said first frequency band and simultaneously receiving radio signals only in said second frequency band and a second antenna set for transmitting radio signals only in said second frequency band and simultaneously receiving radio signals only in said first frequency band;
said dual-type ground-based node includes antenna selection circuitry for selecting one of said antenna sets of a said originating dual-type ground-based node for transmitting said data to said destination ground station having the address included in a said routing message transmitted from an aerial node, said antenna set being selected based at least in part on a composite quality calculated from a quality of a routing message received by said antenna set and a quality of an upstream radio link between said aerial node and another node included in said received routing message; and
said antenna selection circuitry selects a directional antenna of said first or second antenna set for transmitting the data to said destination ground station from said receiving node, said selected antenna being associated with a composite quality higher than the composite quality of any other antenna of either said antenna set as between received routing messages having the same sending ground station address.
