  • Publication number: 20190013988
    Abstract: There is provided a node for operating in a wireless network, including: coarse-granularity scanning circuitry that performs a coarse-granularity scanning process to detect one or more donor nodes of the wireless network according to a first metric. Connection circuitry forms a connection to a selected donor node in the one or more donor nodes. The connection is broken as a consequence of the coarse-granularity scanning process being performed. Fine granularity scanning circuitry performs a fine granularity scanning process to determine a configuration in which a quality of the connection is improved according to a second metric. The connection is maintained during the fine granularity scanning process.

  • Patent number: 10070325
    Abstract: An antenna apparatus for use in a wireless network and method of operating such an antenna apparatus are provided. The antenna apparatus has omnidirectional antenna elements and RF chains, where there are fewer RF chains than omnidirectional antenna elements. A subset of the omnidirectional antenna elements are coupled to the RF chains and sampling circuitry coupled to the RF chains samples the signals received by the subset of the omnidirectional antenna elements. This forms part of a signal detection process in which different subsets of the omnidirectional antenna elements are iteratively coupled to the RF chains. A signal sample spatial covariance matrix for the omnidirectional antenna elements is constructed from the signals sampled by the sampling circuitry at each iteration and a beamforming algorithm applied to the signal sample spatial covariance matrix parameterizes the signals received by the omnidirectional antenna elements.

  • Publication number: 20180213417
    Abstract: An antenna apparatus for use in a wireless network and method of operating such an antenna apparatus are provided. A wireless network controller provides a configuration of such an antenna apparatus, a method of operating such a wireless network controller, and a resulting wireless network. The antenna apparatus comprises a directional antenna and a uniform circular antenna array. The directional antenna can be rotatably positioned about an axis with respect to a fixed mounting portion of the apparatus in dependence on wireless signals received by the antenna array. The antenna array allows the antenna apparatus to receive wireless signals isotropically and thus to accurately monitor the wireless signal environment in which it finds itself. The antenna apparatus can thus monitor and characterise incoming signals, both from external interference sources and from other network nodes, and the directional antenna can then be positioned in rotation to improve the network throughput.

  • Patent number: 10028154
    Abstract: A rotatable antenna apparatus has a fixed unit for attachment of the apparatus to an external structure, and a rotatable unit mounted on the fixed unit and comprising an antenna assembly and processing circuitry coupled to the antenna assembly for signal processing. An interface unit, coupled to both the fixed unit and the rotatable unit, routes a cable to provide a wired connection from the fixed unit to the processing circuitry. The interface unit includes a cable housing within which a coiled length of the cable is enclosed. A control mechanism coupled to the interface unit constrains the amount to which the length of cable is wound and unwound within the cable housing to inhibit application of a stretching stress on the cable during rotatable unit rotation. This provides a very efficient, cost effective mechanism for providing a wired connection to the processing circuitry included within the rotatable unit.

  • Patent number: 9973943
    Abstract: A method and corresponding apparatus are provided for network configuration selection in a wireless network comprising a plurality of nodes. A subset of the nodes are configured to simultaneously participate in a sounding process, in which a node of the subset omni-directionally transmits a predetermined signal and in which other nodes of the subset of nodes sample the predetermined signal as received by an omni-directional antenna array of that node. Measurement reports are received from the subset of nodes, each measurement report comprising a signal source angle and a received signal strength. A path loss is determined in dependence on each measurement report to generate a set of path losses covering a plurality of transmitter node receiver node pairs. Then a directional configuration is selected for a directional antenna of each node of the subset of nodes for data transmission in dependence on the set of path losses.

  • Patent number: 9706419
    Abstract: An antenna apparatus operates as a base station in a wireless network with spatial nulling performed within such apparatus. The apparatus has an antenna assembly employing a selected reception beam pattern. During a nulling test, a reception beam pattern controller causes the assembly to employ each reception beam pattern. Quality metric determination circuitry determines for each reception beam pattern a link quality metric for each of several wireless terminals, based on communication between those wireless terminals and the base station while the assembly employs that reception beam pattern. Reception beam determination circuitry determines, from the various link quality metrics, a reception beam pattern from the reception beam patterns for use for subsequent communication with the wireless terminals. A reception beam pattern can be altered seeking to reduce interference source effects and to maintain an appropriate level of link quality regarding each wireless terminal communicating with the base station.

  • Patent number: 9560676
    Abstract: A wireless feeder network comprises feeder base stations coupled to the communications network and feeder terminals coupled to associated access base stations of the access network. A group of wireless network components form elements of a feeder cluster and the elements of the feeder cluster are connected by an additional communications resource configured to be operated in parallel with the wireless resource of the wireless feeder network. Both a primary and secondary element of the feeder cluster seek to decode at least one resource block allocated to the primary element for reception of data. Information derived from the secondary decoded data is transmitted from the secondary element to the primary element via the additional communications resource. The primary element then performs a revised decoding process additionally using the information received from said secondary element to improve its own decode probability.

  • Publication number: 20160381590
    Abstract: A method and apparatus configures a wireless network comprising a plurality of nodes to mitigate effects of an external interference source. A subset of the nodes simultaneously participate in an external interference sampling process in which each node of the subset samples signals received by an antenna array of that node. A measurement report, comprising a signal source angle and a received signal strength, is received from a node. A location of the external interference source is estimated using the measurement report. The external interference source is then characterised using the estimated location of the external interference source and the received signal strength to calculate for the external interference source at least one of: a source power; a beam width; an antenna bearing; and a front-to-back transmission ratio. The nodes are configured to mitigate effects of the external interference source in dependence on a result of the characterising step.
