A fiber-radio communication network includes a base station () and wireless access nodes () coupled by fiber optic cables (). The base station () includes a switch module () arranged to switch Ethernet signals on a local area network, and a media converter rack module () comprising media converter units MC1-MC6 arranged to convert between a baseband Ethernet signal carried by the fiber optic cables () and an Ethernet digital signal for the switch. The wireless access node () comprises a media converter module () which converts between a baseband Ethernet signal carried by the fiber optic cables and an Ethernet digital signal; and a wireless access point module () comprising a local modem which converts between the Ethernet digital signal received over the fiber optic cables and a wireless transmission in a 60 GHz range for wireless communication with a client terminal () in the vicinity of the wireless access node ().

Fibre-radio communication network and apparatus and fibre-radio communication method

An aircraft-side aircraft data retrieval system and method, comprising: a data storage device () located in an aircraft () adapted to, during a flight, store data acquired during the flight; a transmission element (), for example a dielectric filled hole or a coaxial transmission line assembly, in an external panel () of the aircraft (); and wireless apparatus () adapted to wirelessly transmit, after the aircraft () has landed, the stored data to a ground-side data retrieval system () via the transmission element ().

A bidirectional radio frequency communication unit includes: a transmit modem; a receive modem; an RF transceiver circuit; a coupling waveguide arrangement; and an antenna. The RF transceiver circuit transmits and receives at RF frequencies greater than or equal to 50 GHz. At least a majority of the RF transceiver circuit is provided on a single multilayer PCB. The coupling waveguide arrangement is provided in the form of respective transmit and receive waveguides provided within a diplexer that has a common antenna coupling port and is in the form of a block. The multilayer PCB and the diplexer form a laminated structure; and transition interfaces between the RF transceiver circuit and the waveguide include one or more buried layer probe elements in a buried layer of the multilayer PCB.

Radio frequency communication

An antenna system, comprising: a phased array antenna (); and a dielectric lens arrangement (), for example a single solid dielectric lens () comprising a substantially spherical convex surface () and a concave surface (); wherein the dielectric lens arrangement () is arranged to magnify the effective aperture of the phased array antenna (). The concave surface () is positioned within the near field of the phased array antenna (). The phased array antenna () is operated at a frequency greater than or equal to 50 GHz. The antenna system retains some ability to electronically scan the beam. The antenna system may be for transmission and/or reception. The antenna system may be used for example for communication between two vehicles.

Antenna system

A point-to-point radio frequency (RF) communication system having one or more communication units coupled to respective television cameras and displays; and a further communication unit; wherein the units transmit video data to the further communication unit at frequencies greater than or equal to 50 GHz and at data rates greater than or equal to 1 gigabit/second; and the units receive video data transmitted by the further communication unit at frequencies greater than or equal to 50 GHz and at data rates 250 megabits/second. The units can each include an antenna with a waveguide diplexer and an RF transceiver circuit board having sufficient transmit/receive isolation for the transmitting and receiving to take place point-to-point at distances greater than or equal to 1 km.
