摘要： A respective preferred installation height above ground level is determined for each of a plurality of locations for a subscriber module for receiving a radio link from an access point in a wireless network, the access point having a given height above ground level and a specified location, and the subscriber module being situated within a given geographical area including the location of the access point. The method comprises accessing elevation data for the given geographical area, processing the elevation data to generate a preferred height data file representing a preferred height for a subscriber module to be wirelessly visible by the access point at each of the plurality of locations and processing the required height data file to provide output data indicating the preferred height of the subscriber module as a function of location.

摘要： An antenna array assembly comprises a ground plate, an array of radiator elements disposed in a spaced relationship with a first face of the ground plate between first and second substantially parallel conductive walls projecting from the first face of the ground plate, and a first and second conductive plate. Each of the first and second conductive plates is electrically isolated from the ground plate, and each is disposed in an upstanding relationship to the first face of the ground plate in a substantially parallel relationship with the first and second conductive walls. This provides reduced radiation in at least one direction in the hemisphere on the opposite side of the ground plate to the first face.

摘要： An access point of a wireless communication network forms beams by applying a weightset for a beamforming weights matrix to signal streams. The Equivalent Isotropic Radiated Power (EIRP) that is emitted from an array of antenna elements at the access point is controlled by calibrating the transmission phase and gain of a respective transmit chain for each antenna element, providing a polar radiation model for an antenna element of the array, and determining a weightset for the weighting matrix subject to a constraint that a maximum total EIRP for the beams in combination in any azimuth direction is maintained within a predetermined EIRP limit, based at least on a spatial separation of the antenna elements, the polar radiation model and the calibrated transmission phase and gain of each respective transmit chain.

摘要： Data packets are transmitted from a terminal of a broadband radio communication system. For each transmission cycle in a transmission period data is received at a data interface of the terminal and buffered, and transmission of radio signals comprising the received data is enabled on expiry of a repetition interval from the start of a previous transmission. The repetition intervals are controlled to reduce a proportion of the transmission period for which transmission may occur at an allowed pulse repetition interval of a radar with which the terminal may interfere. The presence of radar pulses is checked during a wait period for each cycle while the terminal is not transmitting. If radar pulses are present, the transmission of radio signals which may interfere with the radar pulses is inhibited.
