A system includes a dual-purpose transmitter sending a video stream over a wireless link to a receiver. In some embodiments, the video stream is generated as part of an augmented reality (AR) or virtual reality (VR) application. The transmitter operates in a first mode to scan and map an environment of the transmitter and receiver. The transmitter generates radio frequency (RF) signals in a first frequency range while operating in the first mode. Additionally, the transmitter operates in a second mode to send video data to the receiver, and the transmitter generates RF signals in the first frequency range while operating in the second mode. ## Claims ### Claim 1 A system comprising: a transmitter configured to: operate in a first mode in which the transmitter generates radio frequency (RF) signals in a scanning pattern to map an environment of the transmitter;
