摘要： A method for ubiquitously covering a selected area with a single wireless communication channel. At least two wireless converters are placed at different locations to provide an aggregated wireless coverage area, the wireless converters covering wirelessly only a respective portion of a selected area with least two portions at least partially overlapping. An OFDM base station transmits a sequence of OFDM signals simultaneously via at least two distribution lines, each OFDM signal modulated by sub-carriers. The wireless converters simultaneously receive, via respective distribution lines, the OFDM signals from the OFDM base station, and up-convert a respective OFDM signal into an RF band to re-transmit wirelessly the respective OFDM signal. At least two re-transmissions of each OFDM signal arrive at a wireless client device. Each sub-carrier from each OFDM signal re-transmission can combine with the respective sub-carrier of the other re-transmissions of said respective OFDM signal, thereby facilitating said ubiquitous coverage.

摘要： 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.

摘要： 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.

摘要： A system operative to transport signals between elements in a vehicle using a shared wire-based medium (SWBM). The system includes at least one transceiver including first and second transmission sources, embedded in the vehicle, in which the first and second transmission sources are configured to generate respective first and second intermediate frequency (IF) signals having respective first and second frequency spans. First and second antennas are co-located with first and second converters, respectively, all embedded in the vehicle. The SWBM interconnects the transmission sources and converters. The system is configured to transport, via the SWBM, the first and second IF signals from the respective first and second transmission sources to the respective first and second converters; up-convert the first and second IF signals into respective first and second radio frequency (RF) signals; and transmit wirelessly the first and second RF signals respectively via the first and second antennas.

摘要： A system operative to replicate an exact frequency match among multiple signals associated with spatial multiplexing. The system includes twisted pairs and a converter configured to receive multiple input signals, in which each of the input signals is an orthogonal frequency division multiplexing signal comprising multiple sub-carriers, and in which input signals are associated respectively with multiple streams generated in conjunction with spatial multiplexing. The converter utilizes a reference signal, associated with an original conversion signal(s) used outside the converter to establish respective frequency ranges associated with the input signals, to reproduce the original conversion signal(s) as respective replica conversion signal(s). The replica conversion signal(s) are used to respectively convert the input signals into output signals all occupying a same single frequency range such that the sub-carriers of each output signal exactly match in frequency, thus enabling wireless transmission and successful decoding of output signals in conjunction with spatial multiplexing.

摘要： An orthogonal frequency-division multiplexing (OFDM) base station operative to transmit a sequence of OFDM signals simultaneously using at least two separate twisted pairs, in which each of the OFDM signals is modulated by a plurality of sub-carriers. At least two converters are connected to the OFDM base station using the at least two twisted pairs, respectively, in which each of the converters, and simultaneously with the other converters, is configured to receive each of the OFDM signals from the OFDM base station using the respective twisted pair, up-convert the OFDM signal into a radio-frequency (RF) band, and re-transmit wirelessly the OFDM signal, in conjunction with the RF band, from at least one antenna associated with each converter.

摘要： 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.
