A:AnswerThis is not a definitive answer to your question because so many particulars may apply, such as building construction materials, number of floors, location of the device, etc. Centrally locating the device will provide the greatest coverage within the home or business. If the device provides a poor signal or no signal to a location/s within your home or business, compatible amplifiers may be able to be purchased and installed to boost the signal strength. I recommend you research and identify compatible amplifiers before committing to your purchase. I have this device and can tell you it broadcasts a strong signal within our 1400sq. ft. home and beyond.
