The present application relates to the field of wireless communication search and rescue, and particularly relates to a radio remote activation method, comprising the following steps: step 1, after a person is in distress, a distress device sends a distress alarm information, and enters a "sleep-work" mode; step 2, after the search device receives the distress alarm information, an activation instruction is sent to activate the distress device; step 3, the distress device receives the activation instruction, adjusts the working parameters of itself with the activation parameters in the activation instruction, and receives a communication instruction. The present application has higher activation efficiency and stronger universality by designing the remote activation instruction with multiple activation parameters; the corresponding activation parameters can be set by the user of the distress device and the user of the search device, and the search device can remotely and reliably activate the distress device; the activation instruction also has control parameters, which can increase the corresponding search and rescue command control ability.
