As the Wi-Fi technology transitions into mmWave bands, there is a growing consensus on the need to support new functions at the Physical (PHY) layer. Generally, this is acheived by extending the PHY-layer header to support new applications (e.g., directional communication, VR), which is costly in terms of overhead. However, one can redesign specific parts of the frame preamble into a reliable data field while maintaining its primary functions. In this talk, we will discuss a technique to convert frame preamble suitable for signaling.

The proposed scheme enables several promising PHY-layer services, such as directional communication, device authentication, etc. At the same time, it allows the legacy systems to process the preamble as normal by being backwards compatible with the standard. Furthermore, we try to apply the signaling to enable directional communication on both sides of the communication link. Through numerical analysis, network level simulations, and testbed experiments, we validate the practicality and reliability of the proposed method.
