Abstract

A routing system of call connection and call routing for radio telephone communications system including cellular radio systems wherein the mobiles transmit on channels in a first band. and the bases transmit on channels in a second band. The routes are selectable from more than one possible route to a desired destination using routing tables to permit different destinations for different calls selectively based on telephone number indications. The system includes multiple blind nodes that do not support direct base to mobile communication. The blind nodes transmitting in the band used for transmission by the mobiles, and nodes receive in the band used for receiving by the mobiles such that the system performs in a limited number of bands of frequencies.

b) utilizing directional or beam antennae for communications between said nodes;

c) providing a first set of beams from a first node, and providing a second set of beams from a second node, a beam from the first node and a beam from the second node comprising a pair;

d) measuring the signal strengths created by pairs of beams; and

e) selecting a beam pair between different nodes with the highest signal strength, for communications by eliminating beam pairs that have the weaker signals,
