Self-configuring communication node arrangement

Abstract

The present invention relates to a communication node arrangement comprising at least two antenna units. Each antenna unit comprises at least one signal port and at least one antenna element, where each signal port is connected to at least one corresponding antenna element. Each antenna unit comprises at least one sensor unit arranged to sense its orientation relative a predetermined reference extension. The communication node arrangement comprises at least one control unit and is arranged to feed a respective test signal into each of at least two different signal ports. For each such test signal, the communication node arrangement is arranged to receive the test signal via at least one other signal port. The communication node arrangement being arranged to determine relative positions of said antenna units based on the received test signals, and to determine relative orientations of said antenna units based on data received from the sensor units.

1 . A communication node arrangement comprising:
 at least two antenna units, where each antenna unit comprises at least one signal port and at least one antenna element, each signal port being at least indirectly connected to at least one corresponding antenna element,
 wherein each antenna unit comprises at least one sensor unit arranged to sense its orientation relative a predetermined reference extension; 
   at least one control unit arranged to feed a respective test signal into each of at least two different signal ports,
 wherein for each such test signal, the communication node arrangement is arranged to receive the test signal via at least one other signal port, and the communication node arrangement is arranged to determine relative positions of said antenna units based on the received test signals, and to determine relative orientations of said antenna units based on data received from the sensor units.
