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.

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.

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.

Abstract: A rotatable antenna apparatus is provided that has both 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 performing signal processing operations. An interface unit is coupled to both the fixed unit and the rotatable unit, and is used to route 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 length of the cable is enclosed in a coiled arrangement. A control mechanism that is coupled to the interface unit is then arranged to constrain the amount to which the length of cable is wound and unwound within the cable housing so as to inhibit application of a stretching stress on the cable during rotation of the rotatable unit. This provides a very efficient and cost effective mechanism for providing a wired connection to the processing circuitry included within the rotatable unit.

Abstract: An antenna apparatus is provided for operating as a base station in a wireless network, along with a method of configuring a transmission beam within such an antenna apparatus. The antenna apparatus has a rotatable antenna assembly that can employ transmission beam patterns selected from a plurality of transmission beam patterns, and has a controller to rotate the rotatable antenna assembly in order to alter an azimuth direction of the rotatable antenna assembly. During a configuration mode, a sweep operation is performed in order to rotate the rotatable antenna assembly to each of multiple selected azimuth directions. Quality metric determination circuitry then determines, for each selected azimuth direction, a link quality metric for each of a plurality of wireless terminals based on communication between the plurality of wireless terminals and the base station whilst the rotatable antenna assembly is at that selected azimuth direction. Transmission beam determination circuitry then determines, from the link quality metrics determined for the plurality of wireless terminals at each selected azimuth direction, both a transmission beam pattern and an azimuth direction to be used for subsequent communication with the plurality of wireless terminals. This provides a particularly efficient mechanism for the antenna apparatus to self configure its transmission beam pattern and azimuth direction.
