  • Publication number: 20190149221
    Abstract: A method of extending RF signals in a wireless control system which includes a first electronic device, a second electronic device, and an RF signal extender. RF signal coverage areas of the electronic devices partially overlap, and each of the electronic devices is out of the RF signal coverage area of the other one. The RF signal extender is in an overlapping area between the RF signal coverage areas, and the electronic devices are in an RF signal coverage area of the RF signal extender. The method includes the steps of: receiving an RF signal with the RF signal extender; analyzing the received RF signal to retrieve the data carried therein; and compiling the data into an RF signal for transmission if the retrieved data follows an RF communication protocol of the wireless control system. Whereby, a total RF signal coverage area can be expanded, and interferences can be reduced.

  • Patent number: 9554322
    Abstract: A transmission control method for a vehicular ad hoc network system having a plurality of mobile nodes is provided. The mobile nodes include a source node, a destination node, and a plurality of relay nodes. The source node transmits a data packet to the destination node through the relay nodes. The method includes each mobile node capturing mobility information being periodically broadcasted from neighboring mobile nodes to correspondingly update the connection state table thereof, wherein the connection state table records the coverage remaining time between the mobile node and neighboring mobile nodes; when any of relay nodes determines that the coverage remaining time between the relay node and the subsequent mobile node is less than a predefined threshold, the relay node transforms into a proxy node, stores the data packet, and establishes a reliable sub-connection between the proxy node and a next proxy node or the destination node.
