  • Patent number: 11071060
    Abstract: Embodiments described herein provide a method for transmitting a wake-up radio packet to low power devices in a wireless local area network. At a wireless access point having a plurality of antennas, data for transmission to one or more lower power wireless devices are received. A wake-up radio packet, including a wake-up data frame, is configured for transmission to the one or more lower power wireless devices. A waveform for transmitting the wake-up radio packet is generated. At each of the plurality of antennas, the waveform is adjusted with spatial mapping to prevent unintentional spatial nulling of the waveform during transmission of the wake-up radio packet. The wake-up radio packet is transmitted, via the plurality of antennas, in a form of the adjusted waveform to the one or more lower power wireless devices prior to transmitting the received data to the one or more lower power wireless devices.

The first function includes a function of transmitting image data to the external device via the first communicator and receiving an operation signal for remote control from the external device. The second function includes a function of receiving the operation signal from the external device via the second communicator. The controller establishes a first connection of the first communication when remotely activated from the external device in a case where the first function is set. The controller establishes a second connection of the second communication after the first connection.

  • Patent number: 10820216
    Abstract: Gateway devices can use dual cellular interfaces to provide reliable communications for client machines. A gateway device can use one of the dual cellular interfaces as a primary interface and the other as a hot backup interface. The backup interface remains connected to a cellular network while communications are routed on the primary interface. Accordingly, the gateway device can rapidly switch communications between from the primary interface to the backup interface. Applications, for example, for ATM payment processing, vending machine telemetry, point of sale payment processing, kiosk internet connectivity, remote monitoring and control, mobile or electronic health, and remote information displays, may run on the gateway devices, on servers, on user devices, or a combination of these devices.

  • Patent number: 10812302
    Abstract: A system for automatically detecting the PHY mode based on the incoming preamble is disclosed. The system includes a multimode demodulator, which includes a preamble detector and a demodulator. The preamble detector is used to determine when the preamble has been received and the PHY mode being used by the sending node. An indication of the PHY mode is supplied to the demodulator, which then decides the incoming bit stream in accordance with the detected PHY mode. In some embodiments, one demodulator, capable of decoding the bit stream in accordance with a plurality of PHY modes is employed. In other embodiments, the system includes a plurality of demodulators, where each is dedicated to one PHY mode.

  • Patent number: 10813045
    Abstract: Embodiments of the present invention relate to the communications field, and disclose an AC, a STA, an AP, and a control method to solve a problem that a STA located in a coverage hole area of a Wi-Fi network cannot access the Wi-Fi network. A specific solution is: a receiving unit receives an access request message sent by a STA; a determining unit determines, sleeping APs managed by the AC and having access ranges covering the STA as first candidate APs; an allocation unit allocates the first candidate AP to the STA as a target AP; and a sending unit sends a wake-up control message to the target AP, and sends an access permission message to the STA. The present invention is used in a control process.
