Abstract: The present invention relates to a transmission method of wireless virtual channels and in particular to the data transmission between wireless host device and child devices. Both of the child device and the host device store a number of sets of family ID and security ID. The child device is the emitter and the host device is the receiver. The child device sends out a set of family ID and security ID by using at least one key or activation unit to the host device that receives and identifies the family ID and security ID. Insertion of the family ID and the security ID to each string of wireless data transmitted between the child device and the host device serves as the certification purpose so that one or multiple data transmission channels can be virtually created.
