Claim One:
1. A device for detecting wireless signals and locating the place of origin in a building, comprising: a transmitter system using a cellular protocol; a plurality of antennae that receive wireless Radio Frequency (RF) signals, each antenna having a port and one antennae is denoted as a reference antenna; a receiving system connected to the antennae ports with a plurality of cables, converting the RF signal to voltage waveform; a processing system in communication with the receiving system, detecting the strength of the received signals and Time Difference of Arrival of the RF signals with respect to antennae and determining the location where the wireless signals are being emitted by using classification algorithms, the processing system including preprocessing software that filters voltage signals and determines features of the voltage signals including signal strength and Time Difference of Arrival to the antennae with respect to the referenced antennae; and a human machine interface.
