1. A method of using multiple radio data streams to thwart man-in-the middle (MITM) transmissions, the method comprising:
dividing a single data transmission into N radio data streams, N being an integer greater than one; and
transmitting the N radio data streams to a station through spatially separated radios such that when (i) the station receives M radio data streams and M is a positive integer differing from N, or (ii) the station receives spatially uniform radio data streams, the station rejects the received radio data streams as including a MITM transmission.
