In order to realize low-cost wireless networking, a local networking mode is generally adopted, a public flue is used as a wireless channel, and the range hoods or valves of all kitchens are wirelessly networked, but when wireless communication is performed in the public flue, serious shrinkage conditions of communication distances can occur, for example, a wireless communication mode of realizing a distance of more than 1 km under open conditions is often performed, and the distance in the public flue is often less than 100 meters. Because the narrow interior space of the common flue can cause very large signal attenuation.
In the related art, in order to improve the signal attenuation situation, the common practice is to increase the transmitting power of the wireless device, and the increase of the transmitting power can aggravate the multipath effect in the public flue, and the interference can also increase synchronously, so as to influence the wireless transmission effect; furthermore, the country has strict restrictions on the transmission power of the radio, and in another way, the failure rate of communication can be reduced by high-frequency communication, but this way can lead to a significant extension of the response time; there is also a way to implement the distance expansion by the skip technology, but this way requires that the relay point be on-line in real time, and seriously depends on the relay point, which may cause communication failure when the relay point is powered off.
