A method comprising: establishing a first wireless optical broadband data link between a first mobile narrowbeam transceiver positioned on a vehicle and a first fixed narrowbeam transceiver mounted along a prescribed path of the vehicle; the first mobile narrowbeam transceiver maintaining connection with the first fixed narrowbeam transceiver until detecting the vehicle has reached a first prescribed path position along the prescribed path; in response to detecting the vehicle reaching the first prescribed path position switching from the first wireless optical broadband data link between the first mobile narrowbeam transceiver and the first fixed narrowbeam transceiver to a second wireless optical broadband data link between the first mobile narrowbeam transceiver and a second fixed narrowbeam transceiver mounted along the prescribed path after the first fixed narrowbeam transceiver by slewing of at least one of the first mobile narrowbeam transceiver, the first fixed narrowbeam transceiver and the second fixed narrowbeam transceiver to a prescribed acquisition position for the second fixed narrowbeam transceiver, thereby enabling the vehicle to maintain continuous broadband access to a wide area network via a prescribed sequence of the fixed narrowbeam transceivers along the prescribed path, wherein the first mobile narrowbeam transceiver and the first and second wireless optical broadband data links are positioned in a forward facing direction relative to the prescribed path of the vehicle to establish a forward wireless broadband channel providing the continuous broadband access; establishing a reverse wireless broadband channel by establishing a third wireless optical broadband data link between a second mobile narrowbeam transceiver positioned in a reverse facing direction on the vehicle and a third fixed narrowbeam transceiver mounted along the prescribed path; the second mobile narrowbeam transceiver maintaining connection with the third fixed narrowbeam transceiver until detecting the vehicle has reached the first prescribed path position along the prescribed path; and in response to detecting the vehicle reaching the first prescribed path position switching from the third wireless optical broadband data link to a fourth wireless optical broadband data link between the second mobile narrowbeam transceiver and a fourth fixed narrowbeam transceiver mounted along the prescribed path by slewing of at least one of the second mobile narrowbeam transceiver, the third fixed narrowbeam transceiver and the fourth fixed narrowbeam transceiver to a prescribed acquisition position for the fourth fixed narrowbeam transceiver, thereby enabling the vehicle to maintain continuous broadband access to the wide area network. establishing a first wireless optical broadband data link between a first mobile narrowbeam transceiver positioned on a vehicle and a first fixed narrowbeam transceiver mounted along a prescribed path of the vehicle;
