  • Low-power wireless mesh network
    Patent number: 11166138
    Abstract: A wireless mesh network includes multiple low-power nodes. When functioning as a data receiving node or a data relay node, each low-power node is used to monitor data transmission at intervals. Each node performs time synchronization based on an SFN and an H-SFN of a base NB-IoT cell. At least one of the multiple low-power nodes is located in the base NB-IoT cell.
    Type: Grant

  • Event alarm device and event alarm system
    Patent number: 10930137
    Abstract: An event alarm device includes a sensor, a notification unit, a MESH communication unit, an NB-IoT communication unit, and an MCU. The NB-IoT communication unit is configured to upload the data measured by the sensor. The MCU is configured to detect a specific event according to the data measured by the sensor. When detecting the specific event, the MCU is configured to instruct the notification unit to emit an on-site alarm, instruct the NB-IoT communication unit to send a first warning signal, and instruct the MESH communication unit to send a second warning signal.
