If there are obstacles between the receiver and the transmitter, expect a reduction in the operating range for: wood and plaster by 5 to 20%, brick by 20 to 40%, and reinforced concrete by 40 to 80%. In the presence of metal obstacles, the use of radio systems is not recommended due to a significant reduction in the operating range. High-power overhead and underground power lines as well as GSM network transmitters located in close proximity to the devices also negatively impact the operating range.
