RADIO LINK BACKUP SYSTEM

摘要

A radio link backup system includes a first device and a second device; the first device includes a first controller and at least two first radio transceivers; the two first radio transceivers have the completely same working parameters; the first controller controls that only one of the first radio transceivers is in the working state at a certain time; the second device includes a second controller and at least two second radio transceivers; the two second radio transceivers have the completely same working parameters; the second controller controls that only one of the second radio transceivers is in the working state at a certain time; the working parameters of the first radio transceiver match the working parameters of the second radio transceiver, which thereby enables the establishment of the radio connection between the first radio transceiver and the second radio transceiver.
