Spectrum monitor system and apparatus for radio coverage testing

A method for measuring and recording RF signal strengths received outside a building from transmissions within the building, where the location selected to receive the in-building transmissions further comprises a radio receiver capable of receiving, measuring, and recording the RF signal strengths from in-building transmissions;

• the method comprising:
• starting a test run on a selected floor within the building;
• transiting the radio transmitter through the selected floor within the building, and, during such transiting, selectively keying the radio transmitter at regular intervals;
• logging, at the location selected to receive in-building transmission, at least the date, time, receive frequency, and RF signal strength received from the selectively keyed radio transmissions.

A system for measuring and recording RF signal strengths received by a radio receiver inside a building from transmissions emitted by a radio transmitter outside the building;

• the system comprising:
• a receiver and demodulator for RF signals;
• a signal-processing computer;
• the receiver and demodulator operatively connected to the signal-processing computer;
• the signal-processing computer comprising a software-defined radio;
• the signal-processing computer capable of causing at least one radio transmitter remote from the building to transmit on a preselected frequency;
• the software-defined radio having an output representing the frequency and signal strength of signals received from the remote radio transmitter so caused to transmit;
• the signal-processing computer operatively connected to a remote computer server;
• where the remote computer server comprises a computer program for correlating the output of the software-defined radio with the location of the signal-processing computer within the building.

A system for measuring and recording RF signal strengths transmitted by one or more radio transceivers inside a respective one or more buildings;

• the system comprising:
• a receiver and demodulator for RF signals;
• a signal-processing computer;
• the receiver and demodulator operatively connected to the signal-processing computer;
• the signal-processing computer comprising a plurality of software-defined radios;
• the signal-processing computer capable of causing at least one of the one or more radio transmitters inside the one or more buildings to transmit on a preselected frequency;
• each of the plurality of software-defined radios having an output representing the frequency and signal strength of signals received from at least one or more of the radio transmitters inside the one or more buildings;
• the signal-processing computer operatively connected to a remote computer server;
• where the remote computer server comprises a computer program for correlating the output of the plurality of software-defined radios with the location of the one or more radio transmitters inside the one or more buildings.
