18. A system including:
a plurality of transmitters, each transmitter having associated therewith a reflector antenna configured to substantially reflect signal transmission toward a detection area; and
a non-transitory computer readable medium including a computer program executable by a mobile device, wherein execution of the computer program configures the mobile device to:
receive transmitter signals from at least two transmitters from the plurality of transmitters;
determine a first mask value based on a discrepancy between a first mean value of the received signal strength for signals received from a first pair of the transmitters of the plurality of transmitters and a second mean value of the received signal strength for signals received from a second pair of the transmitters of the plurality of transmitters; and
determine if the mobile device is located in the detection area in the event that one or more first criteria are satisfied based on masking the mean value using the first mask value.
