Toward a stand-alone monitoring system for mobile telephony base stations exposure using simulations and smartphones crowdsourcing

Monitoring of people electromagnetic waves exposure to mobile telephony base stations is of interest for local communities, in order to communicate towards inhabitants or to enforce local exposure rules. This could be achieved with measurements but they quickly become outdated due to the ever changing network. Furthermore this could be very expensive for a large number of measurement spots. On the other hand numerical simulation gives accurate results but need precise antenna description (location, power, radiation diagram, \dots). Unfortunately such precise information is not publicly available. Nevertheless nowadays most terminals are smartphones that give access to information (received signal strength, location with GPS) that allow them to be used as cheap, low-quality sensors.
