Remote control is a wireless transmitter, through modern digital coding technology, the key information is encoded, through the infrared diode emit light waves, light waves through the receiver’s infrared receiver will receive infrared information into electrical information, into the processor for decoding, demodulation of the corresponding instructions to reach the control set-top box and other equipment to complete the required control requirements. So what are the factors that affect the distance of the remote control? Here’s a simple look:
1. Transmitting power
If the transmitting power is large, the distance is far, but the power consumption is large, and the harassment is easy to occur;
2. Takeover vividness
The takeover vividness of the receiver increases, the remote control interval increases, but it is easily disturbed to form misoperation or out of control;
3. Antenna
Choose linear antenna, and parallel to each other, remote control interval is far, but occupy a large space, in use to elongate the antenna, straightening can add remote control interval;
4. Height
The higher the antenna is, the farther the remote control interval is, but it is limited by objective conditions.
5. Block
The use of wireless remote control using the national regulations of the UHF frequency band, its diffusion characteristics and light approximation, linear dissemination, diffraction is small, between the transmitter and the receiver if there is a wall block will greatly discount the remote control interval, if it is a reinforced soil wall, due to the conductor of the absorption of radio waves, the impact is even more.
The above are the factors that affect the distance of the remote control, I hope to help you. We have more than ten years of remote control production experience of the manufacturer, if you have any questions about the remote control can consult us, we discuss together.
