Simultaneous Using Plural Repeaters At Each Location Patents (Class 455/16)
  • Patent number: 10382091
    Abstract: Methods and apparatus for improving operational and/or cost performance based on filter characteristics. Existing schemes for measuring filter performance are based on a worst case filter performance across a range of frequencies and temperature. Filter performance can be more accurately characterized over one or more frequency ranges. In one exemplary embodiment the frequency is characterized according to a functional (e.g., linear-average) metric. By providing more accurate representation of the reception/transmission filter performance, both network and device optimizations can aggressively manage available power and handle smaller (tighter) margins.

    Abstract: A plurality of repeater devices, each of which may enable forwarding extreme high frequency (EHF) communication between EHF-enabled wireless devices, may form a repeater mesh network. Some or all of the plurality of repeater devices may utilize non-extremely high frequency (non-EHF) control connection in communicating with other repeater devices in the repeater mesh network. The non-EHF control connections may be utilized in establishing, configuring, and/or managing the repeater mesh network. The non-EHF control connections may be also be utilized to enable sending, requesting, and/or receiving periodic and/or dynamic control information. The non-EHF control connections may also be utilized while forming, and/or managing forwarding routes of EHF communication via the repeater mesh network, to enable negotiating and/or setting different isolation techniques among the repeater devices, such as polarization isolation, spatial isolation, and/or use of different frequencies.

  • Patent number: 8970368
    Abstract: Techniques are provided that enable a wireless security system that is designed to detect and receive wireless transmissions in one protocol, to use sensor-transmitters that operate in a different protocol. The techniques involve, generally, the use of an integration device, and in some implementations, first enrolling sensor-transmitters of a first protocol into the integration device, along with device type information for the sensor-transmitters. Thereafter, during system operation, transmissions with message packets in the first message packet protocol are received by the integration device, recognized as having been previously enrolled, and a message packet in a second message packet protocol that includes device type information is then formulated and transmitted by the integration device, for receipt by a system control device for the wireless security system.

  • Patent number: 8965273
    Abstract: Disclosed are a repeater for receiving signals from a base station in a wireless communication system, and a signal receiving method. The base station reports, to each repeater, information on the aggregation level of a relay-control channel element (R-CCE) of a relay-physical downlink control channel (R-PDCCH) via an explicit signaling method or implicit signaling method. In the event the base station reports via an explicit signaling method, the repeater receives, from the base station, information on the aggregation level of R-CCE which is a transmission unit of R-PDCCH, wherein the information contains control information for the repeater. Then, the repeater decodes an R-PDCCH region on an R-CCE aggregation level basis in accordance with the received R-CCE aggregation level information.

  • Patent number: 8958743
    Abstract: Mobile nodes without connectivity to a wireless network form mobile ad hoc networks with mobile nodes with connectivity to the wireless network. The moving directions for the mobile nodes are determined. If the mobile nodes are traveling in substantially the same direction the ad hoc network is formed. The mobile nodes then exchange capabilities. If a mobile node without connectivity to a particular network determines that another mobile node in the ad hoc network is connected to the network, the mobile node without connectivity can tunnel data to the network through the other mobile node.
