Abstract: A shared wired-based medium is deployed inside a vehicle, so as to interconnect various in-vehicle communication components such as radio transmitters, radio receivers, antennas, and processors. The shared wired-based medium is used by each of the communication components to send and receive intermediate-frequency (IF) signals to and from at least one of the other communication components, thereby implementing an efficient in-vehicle IF communication bus, in which each of the IF signals may be a frequency-shifted version of an original signal produced by one of the communication components, and in which such IF signal, after being transported by the shared wired-based medium, is extracted from the shared wired-based medium by at least one of the other communication components, which in turn frequency-shifts the extracted IF signal into a respective radio-frequency (RF) signal capable, for example, of being wirelessly transmitted outside of the vehicle.

Abstract: An access point is located in a first room together with a local plurality of antennas. A plurality of power boosters are located in a second room together with a peripheral plurality of antennas. A wire-based medium connects the first and second rooms. The access point uses the local antennas to transmit wirelessly, in the first room, a plurality of spatially-multiplexed streams, thereby allowing a receiving wireless device in the first room to decode the streams. The access point injects into the wire-based medium, in the first room, a plurality of signals derived respectively from the streams, which are then transported to the second room. The boosters then power-boost the signals extracted from the wire-based medium in the second room, and the peripheral antennas transmit wirelessly, in the second room, the now-power-boosted signals, thereby allowing another receiving wireless device, in the second room, to decode the same plurality of streams.

Abstract: Systems and methods for using spatial multiplexing in conjunction with a coaxial cable deployed in-house. Input streams associated with spatial multiplexing are converted into respective signals occupying different respective frequencies. The signals are transported, via a coaxial cable deployed in-house, into a certain room located in-house, thereby enabling a presence of the plurality of signals in the certain room. The signals are shifted into respective output signals that occupy a single wireless frequency by up-converting each signal from the corresponding different frequency into the single wireless frequency. The output signals are transmitted wirelessly, using only the single wireless frequency, via respective antennas located in the certain room, all said antennas operating in conjunction with the single wireless frequency, thereby achieving spatial multiplexing in the certain room and in conjunction with the coaxial cable.
