Abstract: A central office node using beam patterns and antenna polarizations, a remote node, and a wireless communication method between the nodes. The central office node includes: 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 polarization of the first and second antenna arrays.
