Systems and methods for providing wireless communication between the interior of a moving vehicle (10, C1, C2) and stationary communication systems (11-1A, 11-2A) located along a track of the vehicle (10, C1, C2) are described, with the vehicle (10) having antenna sets (A1, A2) each including a plurality of antennas (A11,A12, A21, A22) mounted onto the vehicle (10) wherein said plurality of antennas has at least two pairs of antennas orthogonal polarization with respect to each other and wherein within each pair the antennas are configured to have full pattern diversity with a first antenna (A11, A21) of each pair oriented to receive/transmit signals essentially in direction of travel and a second antenna (A12, A22) of each pair oriented to receive/transmit signals essentially in direction opposite to the direction of travel and the stationary communication system (11-1, 11-2) comprising antenna systems (11-1A, 11-2A) for providing during operation two cross-polarized RF antenna corridors (17-1, 17-2) in the opposite directions along the track (19) and wherein the RF antenna corridors (17-1, 17-2) overlap along a section of the track, and receiving / transmitting two independent signal channels (s5, s6) over the first cross-polarized RF antenna corridor (17-1) and receiving/transmitting two further independent signal channels (s7, s8) over the second cross-polarized RF antenna corridor (17-2).
