  • Publication number: 20070165695
    Abstract: A method of allocation transmission channels of a frequency band to has each of a plurality of remote stations monitor all channels of the frequency band in its area for the presence of transmissions from stations not part of the network. Each remote station transmits its clear channel list to a master station that aggregates the clear channel list into a reservation map, or map of channels that are clear to all stations in the network. The master station then transmits the reservation map to all stations of the network. The individual stations use the channels of the reservation map to transmit information to the master station. Preferably transmission is accomplished using frequency hopping using a set of channels selected from the reservation map.

  • Publication number: 20070165664
    Abstract: A network of stations uses bandwidth assigned to primary users on a secondary user basis. The stations having a status of needing to send information indicate a need for transmission access by transmitting, simultaneously with transmissions indicating a need for transmission access from other stations of the network, an indication of status to a master station. Each station indicating need for transmission access transmits that indication of status on a respectively different frequency. The master station then grants access to the transmission bandwidth to the requesting stations.

  • Publication number: 20070019603
    Abstract: A bandwidth usage control methodology uses the clear channel detection and frequency agile functionality of a spectral reuse transceiver to effectively ‘aggregate’ disjoint user channels into an overall bandwidth, the spectral extent of which is at least sufficient to meet a high bandwidth requirement (such as, but not limited to the transmission of data/video), that cannot be realized by a conventional, single channel radio.

  • Publication number: 20070008875
    Abstract: A ‘smart’ sub-channel hopping control mechanism executes one or more sub-channel selection discriminators to enable the communications controller of a spectral reuse transceiver to delineate on which of a plurality sub-channels the spectral reuse transceiver may transmit, so as to substantially reduce the likelihood of triggering squelch circuits of silent radios of primary (licensed) channel users.

  • Publication number: 20050239108
    Abstract: The invention relates to methods and kits for detecting and/or monitoring biological molecules in a test sample. For example, the invention relates to methods and kits for detecting and/or monitoring HIV p24 antigen in human body fluid, biological toxins such as ricin or botulism in an environmental or biological sample, and prion protein from human, deer or bovine, such as PrPSC, in a biological sample. The antigen detection signal is boosted by amplification of a polynucleotide linked to a detector molecule using methods for nucleic acid amplification technology.

  • Publication number: 20050030929
    Abstract: A system monitors and detects unauthorized wireless LAN access points and wireless devices. The system includes one or more wireless LAN monitoring devices, which detect and report the presence of unauthorized or “rogue” wireless LAN access points or wireless devices within a predetermined area, for example, within the vicinity of a wired LAN, including indoor and/or outdoor areas. Improved range is achieved through the use of preamplification and sectorized antennas. Larger areas may be covered using additional wireless LAN monitoring devices, which operate independently or cooperate together in the detection process. Geolocation is possible using single or multiple, cooperating monitoring devices. Provision can be made for monitoring devices to provide packet filtering on a wired LAN.

  • Patent number: 5355374
    Abstract: A communication network having a master and a plurality of remotes, these remotes supporting a plurality of co-services, in which access to inbound frequencies among the remotes is shared. When a need by a remote for an extraordinary amount of bandwidth is detected, a reserved spillover frequency from a set of frequencies is reserved for that remote. This bandwidth is reallocated when the need for extraordinary bandwidth for that remote has ended.
