    To build the transmission damage model of quantum entanglement signaling in free space, the relationship between transmission distance and signaling damage degree was proposed. A relay scheme of quantum entanglement signaling and its repairing strategy were put forward. The simulation results show that transmission damage degree is closely related to transmission distance and positioning loss under the three conditions of the telescope’s aperture of the sending and receiving ends and transmission factor and the carrier photons wavelength are constant. And the positioning loss has a little effect on the transmission damage degree. Therefore, the transmission distance is the main factor of the signaling damage. Quantum signaling long distance transmission in free space need to add on repeaters.
