¡¡¡¡5. At present, the UHF band is used for wireless remote control according to the national regulations. Its propagation characteristics and light are nearly linear propagation, and its diffraction is very small. If there is a wall block between transmitter and receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, it will be more affected due to the influence of the absorbed command wave.
