All of the technologies mentioned in your article rely on either Bluetooth or GPS. Could you please comment on the efficacy of such Bluetooth and GPS solutions, considering the signals emitted from both technologies register interactions from upwards of 30 feet (10 meters) away? Is there a danger to this much false positive reporting? In a city like Manhattan, solutions using Bluetooth or GPS would penetrate walls and floors, and very easily over-report interactions. Have you explored ultrasonic contact-tracing solutions instead?
