[Description]Remote control from remote distance (Remote distance of RF Remote Control) of the main factors are as follows [1
Remote control from remote distance (Remote distance of RF Remote Control) of the main factors are as follows [1]:
1, the transmission power: the distance and transmit power, but power consumption is large, prone to interference;
2, the receiver sensitivity: Receiver improve receiver sensitivity, remote control distance increases, but susceptible to interference caused by malfunction or loss of control;
3. Antenna: The antenna is straight and parallel to each other, remote distance, but it occupies a large space, in the use of the antenna stretched, straightened to increase the distance between the remote control;
4, height: the higher the antenna, the farther away the remote control, but by objective conditions;
5, stop: the currently used wireless remote control using state of the UHF band, and its propagation characteristics and light approximation, linear propagation, diffraction is small, between the transmitter and the receiver, if the barrier wall will be greatly discounted remote distance, if it is reinforced concrete walls, due to the absorption of the conductor on the radio, the impact even more.
