  • Patent number: 11017670
    Abstract: Vehicle-to-vehicle (V2V) communication through short range communication techniques can be extended by sending messages from a host vehicle to a target vehicle using an intermediate vehicle. The host vehicle identifies road conditions which may be of interest to a target vehicle. An intermediate vehicle relays the message detailing the identified road conditions from the host vehicle to the target vehicle. The message can be rebroadcast by the intermediate vehicle to target vehicles in its communication range, or it can generate a new message to transmit the information to target vehicles.

    Abstract: A high frequency signal is down-converted into an intermediate frequency signal, transmitted over a limited bandwidth medium from a master unit to a remote unit and up-converted back into its original high frequency at the remote unit. The up-conversion is aided by reconstruction of a reference signal embedded at the master unit as a carrier for a management signal which is transmitted to the remote unit through the same limited bandwidth medium together with the intermediate frequency signal. The reference signal is reconstructed using a phase locked loop which includes a charge pump and is kept stable during intervals between bits and messages by a charge pump shutter.

  • Patent number: 8787269
    Abstract: A method for communicating with a relay station is disclosed. The method for communicating with a relay station comprises transmitting resource allocation information of downlink traffic and uplink traffic from a base station to the relay; and transmitting the downlink traffic to the relay by encapsulating the downlink traffic in accordance with the resource allocation information and receiving encapsulated uplink traffic from the relay in accordance with the resource allocation information. It is possible to enable efficient communication through a relay using a minimum interface without deterioration of throughput even in the case that a base station does not know detailed attributes of a relay existing in a system. Also, it is possible to coordinate collision through a master relay in case of a system supporting multi-hop relays.

  • Publication number: 20140199990
    Abstract: A wired network may be used to carry signals for a wireless network, in a frequency-shifted manner, to extend the range of the wireless network. A wired network may detect signal interference emanating from a wireless service provider, and received through a leak in the wired network's infrastructure. Devices may be installed or leveraged in the vicinity of the interference to extend the wireless service to geographic areas that may have poor reception. The devices may amplify wireless downstream signals and transmit them wirelessly, and may receive upstream wireless communications and transmit them upstream in the wired network's protocol.

  • Patent number: 8724526
    Abstract: A system is described for transmitting a communication signal between power lines. The system includes: a transmitter which outputs an OFDM or an FM-OFDM signal at a radio frequency greater than 200 MHz; a first power line which receives the OFDM or the FM-OFDM signal from the transmitter and radiates the OFDM or the FM-OFDM signal from a conductor of the first power line; a second power line which wirelessly receives, by a conductor of the second power line, the OFDM or the FM-OFDM signal radiated from the first power line, and a receiver connected to the second power line which receives the OFDM or the FM-OFDM signal from the second power line.

  • Publication number: 20140106665
    Abstract: There is provided apparatus for propagation of a wireless signal through a barrier comprising a first antenna for location on a first side of the barrier, a second antenna for location on a second side of the barrier and a waveguide. The waveguide comprises a conducting member passing through the barrier between the first and second sides. The conducting member is held within an insulator sleeve such that it is spaced from a surrounding metal wall of the waveguide. A wireless signal received by the waveguide on the first side of the barrier is transmitted through the barrier by Transverse Electro-Magnetic (TEM) mode propagation along the waveguide is re-radiated on the second side.

  • Publication number: 20140011443
    Abstract: A first network node of a cellular system is configured for communication with a second network node over a twisted pair wire. The first network node includes a receiver for receiving, over the twisted pair wire, an intermediate frequency signal from the second network node, which intermediate frequency signal has been converted from a high frequency signal having a frequency higher than the frequency of the intermediate frequency signal by the second network node, and a down-converter for converting the intermediate frequency signal to a low frequency signal having a frequency lower than the frequency of the intermediate frequency signal. The first network node also includes an up-converter for converting a received low frequency signal to an intermediate frequency signal having a frequency higher than the frequency of the low frequency signal.

    Abstract: A multi-mode convergence method, a multi-mode combination method, and devices thereof are provided. The multi-mode convergence method includes the following steps. Data from multi-mode base band units (BBUs) is received and separated into downlink service data and operation maintenance data. A channel configuration is generated according to the operation maintenance data. The downlink service data of a corresponding mode is selected according to the channel configuration, and the downlink service data and the operation maintenance data are consolidated, and the consolidated data is sent to corresponding remote radio unit (RRUs). The multi-mode convergence method, the multi-mode combination method, and devices thereof are adopted, so as to accomplish functions, such as multi-mode and pseudo noise (PN) multiplexing, to decrease complexity of a multi-mode system, and provide a function of multi-mode coexistent optical fiber.
