This document provides a review of the fundamental and latest technologies related to forward transmission-based sensing, discusses its benefits and limitations, especially with respect to the backscattering-based sensing technologies, and proposes some practical use cases. It is shown that this technology can work well with IOWN’s Open APN and can provide valuable functions and novel capabilities to the network with little additional modification effort. Therefore, it has great potential for commercialization. Several work items are also raised to ensure that it will provide technical and economical benefit to end users.
