Lack of common adaptation protocols can hinder interoperability between devices from different manufacturers. Standardization bodies (e.g., IEEE 802.15.4 for low-rate wireless personal area networks) are beginning to incorporate adaptive modulation and coding, but fully adaptive FSK features remain proprietary in many products. Future work should push for open adaptation frameworks that specify how devices negotiate parameters, share channel measurements, and fall back to baseline modes when needed.
