High-Speed Wireless Broadband Dual Mode Program

High-Speed Wireless Broadband Dual Mode Program

Programme overview

The system integrates two communication technologies, micro-power wireless and power line carrier, and complements the network topology of wireless and carrier. It can avoid the communication blind spots that exist in each (two communication methods) and provide more and more reliable routing options. Thereby improving the stability of network communication and forming a new local dual-mode communication technical solution with high redundancy, high speed and high stability.

Features of the scheme

  • Full-hybrid routing networking: adopts carrier + wireless full-hybrid dual-mode routing, carrier-to-wireless, and wireless-to-carrier, the two communication modes can be switched freely to obtain a more ideal coverage effect.

  • Rate self-adjustment: realize 10/50/100Kbps rate self-adaptation, and automatically select the highest available rate according to the transmission conditions between two points.

  • Strong anti-interference ability: advanced signal encoding and decoding technology, frequency division multiplexing and frequency hopping technology can effectively jump out of the deep weakened area, avoid wireless interference with the same signal, and ensure the safety of communication.

  • Interception and retransmission Route retransmission: Intermediate nodes in the route have a retransmission function, and the same route will be retransmitted after switching frequency or rate, which can effectively improve the reliability of network communication.

  • Four channel scanning modes: adding a variety of backup channels is conducive to solving the problem that the main channel cannot communicate due to continuous interference in a short period of time, and improving routing reliability.

  • Network-wide perception fault research and judgment: Real-time acquisition of network status: online, offline, etc., to help judge power outages, equipment failures, and improve user experience.

  • Recognition of the reverse connection of the live wire: by analyzing whether the polarity of the zero crossing point is consistent between the sending and receiving points, it is judged whether the live wire is connected reversely

  • Recognition of station-to-house change relationship: Use the carrier function to obtain the node's station-area ownership and to identify the station-to-house change relationship.
