A municipal smart-building team needs room-level occupancy with coin-cell sensors that must last years. Wi-Fi RTT infrastructure is available but power-hungry for the endpoints. Which technology choice best matches accuracy and power needs?
Select an answer to reveal the explanation.
Short Explanation
Tiny battery sensors hate chatting on full Wi-Fi all day. For room-level presence with years of life, lean on Bluetooth-class beacons—not always-on Wi-Fi RTT radios.
Full Explanation
Technology selection for IoT balances accuracy, density, and power. Room-level occupancy with multi-year coin cells typically favors Bluetooth/WPAN beacon or presence designs. Continuous Wi-Fi RTT on constrained endpoints drains batteries; GPS fails indoors; manual counts are not an automated IoT solution.
