Abstract:
1. A method to enhance wireless communications in high-speed vehicles through Doppler-nulling traveling-wave antenna relays, the method comprising: aggregating wireless traffic from a plurality of wireless communication devices at an access terminal on a moving vehicle; and forwarding the wireless traffic to a wireless communication network through a pair of matched traveling-wave directional antennas arranged to transmit and receive signals at a predefined angle such that a Doppler effect on the transmitted and received signals resulting from a motion of a first of the antennas positioned on the moving vehicle relative to a second of the antennas positioned along a path of the moving vehicle introduces zero frequency shift on the signals between the matched traveling-wave directional antennas, wherein the second antenna is conductively coupled to one or more access nodes of the wireless communication network.
