  • Patent number: 9247543
    Abstract: Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired.

  • Patent number: 9247443
    Abstract: Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.

  • Patent number: 9237449
    Abstract: A method and system for detection of available a white space channel in an area of licensed transmitters includes a detector which utilizes the autocorrelation analysis of a channel in an frequency modulated (FM) band. Calculation of the autocorrelation excludes an initial set of correlation delay values such that large values of autocorrelation are removed. The remaining autocorrelation based on higher correlation delay values exposes the sinusoidal nature of an FM transmitter operating in the selected channel. White space becomes available to a user if no transmitter is detected using the autocorrelation detection method.

  • Patent number: 9215737
    Abstract: A method of performing pairing by a transmission terminal in device to device communication is provided. The method includes classifying a plurality of link identifications for identifying a data transmission and reception channel a seed of at least one link identification; selecting an available candidate link identification seed among the seed of the at least one link identification, transmitting a pairing request message including seed information associated with the selected available candidate link identification seed, and receiving a pairing response message corresponding to the pairing request message. When allocating a connection ID in a device to device communication environment, even if a small number of devices exist, an overhead for searching for the connection ID is not great. Further, when many devices exist within a specific range, a probability of devices having the same connection ID is reduced. Accordingly, the device to device communication can be easily performed.

  • Patent number: 9143286
    Abstract: This invention concerns the estimation of signal to noise ratio (SNR) at a communications receiver; it may be applicable to a wide range of receivers but is particularly suited for Orthogonal Frequency Division Multiplexing (OFDM) receivers. In particular the invention is a method, a receiver and software for performing the method. The signal to noise ratio (SNR) in the received signals is estimated by directly estimating the power ratio, in the received signal, between the part of the frequency spectrum of the received signal that contains only noise, and the part of the spectrum that contains both signal and noise; and averaging this value over a time interval.
