Yes, Zigbee uses 2.4 frequency band wireless transmission, which has poor anti-interference ability and is easily affected. It cannot modify and improve the data packets by loading the Zigbee protocol stack independently. winertech communication adopts a fully independently developed communication networking protocol. It has applied for a number of self-developed patents. It has a low-frequency band design and good anti-interference ability. The measured transmission distance can reach 12KM. In addition, the network transmission protocol can support data retransmission. , disconnection reconnection and other multiple mechanisms to ensure the stability of data transmission.
