1. A method comprising:
transmitting a signal from a transmitter of a wireless device;
receiving, using a receiver of the wireless device, a signal from a radio frequency identification (RFID) device, the signal comprising one or more resonance parameters, the transmitter and receiver being configurable to be toggled from a first operational mode used for wireless communications protocol operations to a second operational mode used for RFID scanning operations, wherein the wireless communications protocol operations are used for data transmission over a wireless network and are different than RFID scanning operations; and
generating sensing information and an estimated distance value based, at least in part, on the received signal, the sensing information representing a sensed condition at the RFID device, and the estimated distance value representing an estimate of a distance between the wireless device and the RFID device.
