Patent number: 8081929Abstract: Methods and systems for optimal frequency planning for an integrated communication system with multiple receivers may include adjusting a center frequency of a low IF signal to reduce interference by a second order interference signal. The center frequency may be adjusted to avoid high power portions of the second order interference signal. The interference level corresponding to a center frequency may be determined by, for example, a SNR of the low IF signal, or by determining a BER for the low IF signal. The center frequency of the low IF signal may be dynamically adjusted to keep second order interference level at an acceptable level. Adjusting the center frequency of the low IF signal may also comprise keeping the low IF signal from being blocked by a DC component of the second order interference signal.Type: GrantFiled: June 5, 2008Date of Patent: December 20, 2011Assignee: Broadcom CorporationInventors: Brima Ibrahim, Alireza Zolfaghari, Steven Hall, Kambiz Shoarinejad, Bojko Marholev

Publication number: 20110223906Abstract: In a cellular wireless system, power thresholds used for determining whether or not to add or drop servers held in a set of servers, such as an active set, for serving a user equipment are determined on the basis of the motion of the respective user equipment. A lower threshold may be used with respect to the adding or dropping of a given server to or from a set of servers for serving a fast moving user equipment than would be used for the same server with respect to its adding or dropping to or from a set of servers for serving a slow moving user equipment, while maintaining a given quality of service. As a result, the average number of servers held in sets is reduced in a typical network that comprises a plurality of user equipments moving at different speeds, compared to a situation in which the threshold is set irrespective of the motion of a user equipment.Type: ApplicationFiled: May 25, 2011Publication date: September 15, 2011Applicant: NORTEL NETWORKS LIMITEDInventors: Steven Hall, Steven Baines, David Bevan, 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: 20100046496Abstract: Aspects of a method and system for Bluetooth connection setup in a multi-standard multi-radio communication system are provided. In this regard, a Bluetooth system may be operable to determine whether a coexistent time division multiplexing communication system is receiving signals and to control the types of packets it transmits based on the determination. While the coexistent time division multiplexing communication system is receiving signals, the Bluetooth system may be limited to transmission of Bluetooth packets that enable establishment of a Bluetooth connection. For example the Bluetooth system may be limited to sending ID packets in response to page packets and FHS packets and/or may be limited to sending FHS packets. Also, the Bluetooth system may refrain from transmitting packets while the Bluetooth system is connected as a piconet master and while the time division multiplexing communication system is receiving.Type: ApplicationFiled: June 10, 2009Publication date: February 25, 2010Inventor: Steven Hall

Patent number: 7561526Abstract: A communications network comprises a plurality of linked nodes between a source and a destination. At each node the state of the network and its links are measured and stored with advertisements from other links. The node also performs a routing algorithm to define the instantaneously best path to the destination for the current network state. The routing algorithm responds to a plurality of metrics, including costs of links, and may use fuzzy logic which derives a fuzzy cost for candidate paths to derive a least fuzzy cost path to be followed. Traffic is shared between a path which is determined to be the best, at the current point in time, and a path which has previously been determined as the best path. The network can be a network which carries mobile cellular traffic.Type: GrantFiled: December 17, 2002Date of Patent: July 14, 2009Assignee: Nortel Networks LimitedInventors: James M Naden, Christopher J Reed, Steven Hall, Andrew P Winsor
