Product Overview:

At present, the upstream channel of the electricity information collection terminal is mainlyGPRSperhapsCDMAIn practical applications, most concentrators and specialized transformer terminals are installed in basements. Due to weak or even no mobile signals, the communication between the acquisition terminal and the acquisition system main station cannot be established or is unstable. Our company's latest research and developmentYCTXZJ-M-BOOST10The type of public network communication repeater adoptsLoRaWireless communication technology can effectively solve the problem of blind spots in mobile signals and improve the success rate of electricity information collection.
