METHOD AND SYSTEM FOR SWITCHOVER OF LOOPED NETWORK WIRELESS APPARATUSES

Disclosed are a method and a system for switchover of looped network wireless apparatuses. The wireless apparatuses comprise a core wireless apparatus and a remote wireless apparatus. The core wireless apparatus and more than two remote wireless apparatus form a looped network through two ports of the core wireless apparatus. The method comprises: when detecting that a line bit error rate of two ports of a core wireless apparatus is in a set threshold range, the core wireless apparatus sending valid control characters, and when detecting that the line bit error rate is not in the set threshold range, the core wireless apparatus sending an invalid control character, the valid control characters sent by the two ports of the core wireless apparatus are different; when detecting a line bit error rate of a receiving side of a master port of a remote wireless apparatus is in a set threshold range, the remote wireless apparatus forwarding the valid characters received by ports to the master port, when detecting the
