  • Patent number: 7382804
    Abstract: The present invention provides a bandwidth efficient system and method of measuring the range between nodes (102, 106, 107) in a wireless communications network (100) with one-way data transfer, where each node (102, 106, 107) periodically transmits a message that contains information regarding neighboring nodes (102, 106, 107) from which any prior messages have been received by the transmitting node (102, 106, 107). A node (102, 106, 107) receives the messages transmitted from neighboring nodes (102, 106, 107) in the network (100), and records the times of arrival of the received messages. The node (102, 106, 107) receiving those messages can thus determine the respective distances between itself and the neighboring nodes (102, 106, 107) based on the respective time of arrivals of the received messages and the respective information included in the respective messages.

  • Patent number: 7369846
    Abstract: A set of performance-related data that represents both normal and abnormal conditions in the network is determined and stored in a mobile station MS. The set or a sub-set of this data is transmitted to a computer for analysis upon a triggering event, and the MS user is informed of the analysis results. The triggering event is receipt by the MS of an encrypted message to transmit the set or sub-set of the data. The MS decrypts the received message using an associated public key stored in the MS and transmits the set or the sub-set of the performance-related data only in response to correctly decrypting the encrypted message. The public key is one of a set of public keys stored in the mobile station, wherein individual members of the set are associated with applications executable by the MS in cooperation with a received encrypted command or encrypted data set.

  • Patent number: 7363011
    Abstract: A method and a correspondingly operative radio receiver (10) (in either user equipment or a base transceiver station of a cellular telecommunication system) by which the radio receiver (10), in receiving signals transmitted over a radio channel, estimates the impulse response of the radio channel (so as to account for changing conditions of the radio channel) based on a received training sequence (Y) included in the received signal and corresponding to a transmitted training sequence (X), the method including a symbol averaging process (101) by which in effect, by using a calculated correlation sequence (Yc?), two sets of correlations are performed (i.e. a so-called double correlation) without actually performing two sets of correlations, and so improving the estimate of the channel impulse response to the same extent as would result from performing two sets of correlations but with fewer processor operations.

  • Patent number: 7363008
    Abstract: The invention provides methods for autonomous detection and adaptation with respect to an interfering signal on a frequency channel to assist a wireless device on a wireless network in choosing an appropriate frequency channel. According to embodiments, a method determines an appropriate channel by first detecting whether there is an interfering signal on a frequency channel over the wireless network, then retrieving data from the interfering signal to retrieve protocol identification information. Prior to determining whether to transmit over the frequency channel, the method calls for determining whether the identified protocol of the interfering signal is a predetermined protocol.

  • Patent number: 7359676
    Abstract: This application is directed to systems and methods for adaptively scanning for wireless communications. Scan data associated with scanning one or more wireless network channels based upon a scan pattern is received. Each wireless channel has a designation of primary or secondary with at least one channel having the secondary designation. A determination is made as to whether anomalous activity is present on a selected wireless channel designated as secondary. If anomalous activity is determined to be present, at least one scanning parameter of the selected channel is altered.

  • Patent number: 7353004
    Abstract: The system of a content head end of a distribution system includes a program multiplexer, a multi-channel modulating module, a channel multiplexer, a digital-to-analog converter and a frequency block-up converter, all arranged in a sequential configuration. Packets representing respective content programs are fed to the program multiplexer. The program multiplexer multiplexes the packets into an output queue. Packets from the output queue are then fed to the multi-channel modulating module. The multi-channel modulating module receives the packets and routes them to various modulators representing corresponding RF channels. The various modulators then modulate the respective packets to generate corresponding RF signals. These RF signals are then multiplexed by the channel multiplexer into a multi-channel RF signal. The multi-channel RF signal is then forwarded to the digital-to-analog converter for conversion into an analog, multi-channel RF signal.

  • Patent number: 7333775
    Abstract: A method detects which radio communication terminals use interference suppression procedures, in a radio communication system. Here radio communication terminals periodically return measurement signals which represent radio field characteristics and/or reception situations determined at the radio terminal to a base station and compare these signals with one another and also with threshold values determined on the base station side. The comparisons conducted are used for assigning radio communication terminals to groups, with a first group being assigned those radio communication terminals which display a good reception situation during the threshold value comparison, whereas a second group is assigned all further radio communication terminals.

  • Patent number: 7280836
    Abstract: A computing arrangement may include a first radio transceiver operating in accordance with a first communication protocol using a frequency band and a second radio transceiver operating in accordance with a second communication protocol using the frequency band. An access point operates in accordance with the first communication protocol and transmits a communication signal that has a frame including a first time interval indicative of when communications using the first communication protocol via the frequency band are permitted to the computing arrangement. The computing arrangement determines if the frame includes a second time interval, which is indicative of and is reserved for exclusive communications in accordance with the second communication protocol. If the second time interval is absent from the frame, the computing arrangement inserts the second time interval into the frame. The computing arrangement communicates with a further device only during the second time interval.

  • Patent number: 7280822
    Abstract: A wireless communications network comprises a server in a central location storing matching profiles for a plurality of users of the network. The matching profile for each user is stored in the server through the user's mobile unit or a secure page on the Internet. Each matching profile is corresponded with a respective mobile unit using the same identification information (ID) of the respective mobile unit utilized for carrying out phone calls. The server has a customizable variable matching algorithm and probes the matching profiles corresponding to the respective mobile units in a cell or group of cells for a match every time a new mobile unit subscribes into the cell or group of cells. When there is a match of matching profiles, the two persons are put in contact or advised of each other through a phone call or other communications method.
