1. A method comprising:
positioning one or more radio frequency sensors within an electromagnetic environment where a master wireless device and a slave wireless device share a wireless communication interface;
receiving, at the one or more radio frequency sensors, signals transmitted between the master wireless device and the slave wireless device over a wireless connection;
identifying inter-arrival times for packets within the received signals;
estimating communication time slots from identified back-to-back intervals that occur within connection intervals of the packets; and
identifying packets within the wireless connection as being transmitted by the master wireless device or the slave wireless device.
