Abstract  Abstract

At least one user data stream is layer 2/3 processed (Fig.3. ref. 24) physical layer processed (Fig. 3 ref. 26) and radio frequency processed (Fig. 3 ref. 28). A watermark/signature is embedded (Fig. 3 ref. 30) at least one of layer 2/3 (Fig. 3 ref. 24) physical layer (Fig. 3 ref. 24) or radio frequency (Fig. 3 ref.28) producing an embedded wireless communication. The embedded wireless communication is wirelessly transferred (Fig. 3 ref. 36). The embedded wireless communication is received (Fig. 3 ref. 34) and the watermark/signature is extracted (Fig. 3 ref. 34) from the embedded wireless communication.
