摘要： An access point for use in a point to multipoint wireless network comprises a sector antenna and an antenna array of antenna elements, the antenna elements not including the sector antenna, and the antenna elements being arranged to receive signals from the same sector as the sector antenna. A first beamformer is configurable to form a first beam from signals received at the antenna array and a selector switch is switchable to at least a first state in which signals received at the sector antenna are connected to a first receiver, and a second state in which signals received from the first beamformer are connected to the first receiver. A scheduler is configured to set the selector switch to the first state for at least a first receive timeslot and to the second state for at least a second receive timeslot.

摘要： An access point (1) for use in a point to multipoint wireless network comprises a sector antenna (8) and an antenna array of antenna elements (7), the antenna elements not including the sector antenna, and the antenna elements being arranged to receive signals from the same sector as the sector antenna. A first beamformer (10) is configurable to form a first beam (11) from signals received at the antenna array and a selector switch (5) is switchable to at least a first state in which signals received at the sector antenna (8) are connected to a first receiver (2), and a second state in which signals received from the first beamformer (10) are connected to the first receiver (2). A scheduler is configured to set the selector switch (5) to the first state for at least a first receive timeslot and to the second state for at least a second receive timeslot.

摘要： Data is transmitted from a first wireless station comprising first and second transmitters to a second wireless station comprising first and second receivers. In the absence of radio link failure detection, first data is transmitted via a first radio link from the first transmitter to the first receiver using a first subset of first radio resource blocks and transmitting second data via a second radio link from the second transmitter to the second receiver using second subset of the first radio resource blocks. The first and second radio links are monitored for a failure. If first radio link failure is detected, the second radio link is operated using a combination of the first and second subsets of the first radio resource blocks. If second radio link failure is detected, the first radio link is operated using a combination of the first and second subsets of the first radio resource blocks.

摘要： A wireless transceiver for a wireless communication network has an offset Gregorian antenna arrangement comprising a primary reflector dish, an electrically conductive reflector member comprising a secondary reflector and a conductive support wall, a planar array of antenna elements arranged as a feed for transmitting radio frequency signals to the secondary reflector and/or for receiving radio frequency signals from the secondary reflector and a conductive support block configured to support the planar array of antenna elements. The conductive support wall is connected directly to the conductive support block, and the conductive support wall is configured to be substantially perpendicular to the planar array of antenna elements.

摘要： Wireless communication is established between a first station and a second station in a wireless communication system, the first station having a beamforming network configured to form a succession of beams using antenna weight vectors selected from a pre-determined plurality of antenna weight vectors. The orientations of the beams are arranged in a grid comprising a plurality of rows. The beams of each row are spaced in angular position such that at least one beam in a respective row is positioned mid-way between the positions of two beams on an adjacent row. A succession of beams is formed to send first messages using a selected first sub-set of the antenna weight vectors. If a first message in a first beam is received at the second station, a further succession of beams is formed using a second sub-set of the antenna weight vectors selected to form beams adjacent to the first beam.

摘要： A dual polarised edge coupled patch antenna element includes a patch radiator (1) and a ground plane (6), the ground plane being disposed in a substantially parallel relationship with the patch radiator (1). A first feed track (2) is connected at a first feed position on a first edge of the patch radiator and a second feed track (3) is connected at a second feed position on a second edge of the patch radiator, the second edge being at a right angle to the first edge. The first feed position is offset from the centre of the first edge and the second feed position is offset from the centre of the second edge, and the first feed position and the second feed position are each offset in a respective direction away from a corner between the first side and the second side.

摘要： There is disclosed a method for managing a communications system including a wireless network access point and an administrator computing device coupled to the access point via a network. A user device connects to a basic service set hosted by the access point. The administrator computing device accepts a request to configure a single-user service set hosted by the access point, the request received from the user device via the basic service set and the network. The administrator computing device instructs the access point to configure the private single-user service set using configuration information contained in the request. The access point configures the single-user service set using the configuration information.

摘要： There are disclosed methods and access points for estimating a location of a user device in a wireless communications network. A plurality of access points define respective received signal strength indicator (RSSI) values for transmissions received from the user device. Each of the plurality of access points sends the respective RSSI values to the other access points of the plurality of access points. One of the plurality of access points self-elects to estimate the location of the user device. The self-elected access point estimates a location of the user device based, at least in part, on the RSSI values.
