Many indoor sensing applications leverage knowledge of relative proximity among physical objects and humans, such as the notion of "Within arm's reach". In this paper, the authors quantify this notion using "Proximity zone", and propose a methodology that empirically and systematically compare the proximity zones created by various wireless technologies. They find that existing technologies such as 802.15.4, Bluetooth Low Energy (BLE), and RFID fall short on metrics such as boundary sharpness, robustness against interference, and obstacle penetration. They then present the design and evaluation of a wireless proximity detection platform based on magnetic induction - LiveSynergy.
