1. A central office node comprising:
- a first antenna array with first polarization attributes;
a second antenna array with second polarization attributes; and
a transmitter unit configured to transmit data to a plurality of remote nodes using beam patterns generated during beamforming and the polarizations of the first and second antenna arrays,wherein an angle between the beam patterns is calculated based on a distance between a transmitter antenna and a receiver antenna and a distance between remote nodes.
