Patent number: 8514139Abstract: Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. An antenna according to an embodiment of the invention employs an enclosure having an aperture in one end; in preferred arrangements the aperture provides the enclosure with a substantially open end, over which the cover is placed. The cover has a slot therein, of a smaller size than the size of the aperture presented by the open ended enclosure and the slot in the cover then acts as the radiating slot.Type: GrantFiled: December 28, 2007Date of Patent: August 20, 2013Assignee: Apple, Inc.Inventors: David Adams, Andrew Urquhart, William Waddoup, Dean Kitchener, Steven Hall, Simon Gale

Publication number: 20130137452Abstract: The present invention presents a method, arrangement and computer program product for clocking exploiting the relative behavior of clocks of individual receiving stations as well as a corresponding modeling to derive a time difference of arrival of a signal from a user device which can be used to correct the time difference of arrival based on the modeled clock behavior and leads to a correct clocking of received user signals without the need of synchronization of the clocks in the various receiving stations. This principle is applicable to a plurality of pairs of receiving stations and beacon signals transmitted amongst them and allows for a correct location estimation of a user device.Type: ApplicationFiled: January 22, 2010Publication date: May 30, 2013Applicant: ROCKSTAR BIDCO LPInventors: David Bevan, Simon Gale

Patent number: 8437766Abstract: Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fibre links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions antenna configurations that are not ideal for relaying data between base stations.Type: GrantFiled: May 26, 2011Date of Patent: May 7, 2013Assignee: Apple, Inc.Inventors: Simon Gale, Andrew Urquhart

Patent number: 8432929Abstract: A cellular communication system comprising a plurality of geographically spaced base stations (2) each of which comprises an antenna arrangement (4, 6, 8) per base station sector, each of which antenna arrangements has an antenna element for generating an array of narrow beams (10, 12, 14) covering the sector. Timeslots are simultaneously transmitted over each of the beams so as to generate successive sets of simultaneously transmitted timeslots per sector. The timeslots are each split into multiple orthogonal codes, for example Walsh codes. The communication system additionally comprising a scheduling device (31) for allocating for successive sets of timeslots common overhead channels, including a common pilot channel, which are allocated to the same sub-set of codes of each timeslot in the set. For successive sets of timeslots different data traffic is allocated to the same sub-set of codes of each timeslot in the set.Type: GrantFiled: September 13, 2010Date of Patent: April 30, 2013Assignee: Research In Motion LimitedInventors: Fiona Wilson, Simon Gale

Publication number: 20130045767Abstract: A communication system includes base stations having an antenna arrangement per sector. Each of the antenna arrangements has an antenna element for generating an array of narrow beams covering the sector. Timeslots are simultaneously transmitted over each beam to generate successive sets of simultaneously transmitted timeslots per sector that are each split into orthogonal codes. Common overhead channels are allocated for successive sets of timeslots, which are allocated to the same subset of codes of each timeslot in the set. For successive sets of timeslots, different data is allocated to the same subset of codes of each timeslot in the set. This generates a sector-wide beam carrying the common overhead channels and a plurality of narrow beams, each carrying different data. An inter-beam handoff scheme allows the antenna arrangement to simultaneously transmits data to a user equipment located in a cusp region between adjacent beams on the adjacent beams.Type: ApplicationFiled: September 14, 2012Publication date: February 21, 2013Inventors: Fiona Wilson, Simon Gale

Patent number: 8125917Abstract: In a wireless network comprising access points deployed within a designated zone of coverage, the radio frequency field strength resulting from radiation from the access points is optimised as a function of location by means of control of the transmission power and/or radiation pattern of the access points in response to measurements from sensors at defined locations that measure received signal power, the received power being related to radio frequency field strength. Sensors may be deployed within the designated zone of coverage, at the edge of the zone and/or outside the zone and optimization of the transmission parameters of the access points in terms of transmission power and/or radiation pattern is carried out taking into account the location of the sensors in addition to the received power at the sensors.Type: GrantFiled: October 10, 2008Date of Patent: February 28, 2012Assignee: Avaya Inc.Inventors: David Bevan, Simon Gale, Steven Hall, Andrew Jeffries

Publication number: 20110181482Abstract: Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. Conventionally, an antenna of the cavity-backed slot-radiating type comprises a slot formed in an end of an electrically conductive enclosure, which slot may be energised by a radiating element in registration with the slot. A feed network may connect to the radiating element via a transmission line formed by a conductive track on a feed layer located between the enclosure and an electrically conductive cover. A slot is formed in the section of the cover that covers the end of the cavity in which a slot is formed, such that the two slots are of substantially the same size and shape. A problem with this structure is that the cavity is difficult to mould in one piece and it can be difficult to achieve alignment of respective slots; as a result it is relatively costly to manufacture. Also, it is difficult to insert dielectric material into the enclosure to adjust the performance parameters of the antenna.Type: ApplicationFiled: December 28, 2007Publication date: July 28, 2011Inventors: David Adams, Andrew Urquhart, William Waddoup, Dean Kitchener, Steven Hall, Simon Gale

Publication number: 20090186590Abstract: The present invention provides an improved method for calibrating transmitter and receiver circuits in a device having multiple antennas. The method involves transmitting pilot signals from the device to a second device and from the second device to the device. Each device determines the relative differences between the signals received by a first antenna and by each of the other antennas. The relative differences can then be used to calculate calibration factors that can be applied to the transmitter and receiver circuits.Type: ApplicationFiled: January 18, 2008Publication date: July 23, 2009Applicant: NORTEL NETOWRKS LIMITEDInventor: Simon Gale
