It will I'm afraid going to be a difficult battle to win, e.g., - modern iPhones can communicate with global satellite constellations (https://support.apple.com/en-us/HT213885 https://support.apple.com/en-us/HT213885). I imagine this will grow substantially - Even bike lights nowdays have radar built into them (e.g., https://www.garmin.com/en-GB/p/698001 https://www.garmin.com/en-GB/p/698001). Also room presence sensors are beginning to use radar 22GHz. We can now build incredibly cheap and lightweight radio devices up to 80 GHz. They will inevitably be used more on the ground, in air and on satellites as the economics makes new types of uses practical.
