How to avoid two major sources of interference in wireless monitoring

- Dec 12, 2018-

Nowadays, when it comes to wireless monitoring, another word that may be most easily remembered is: interference. It is true that the convenience brought by wireless monitoring has become increasingly apparent, but at the same time it has deepened the fear of interference. In this way, "wireless monitoring" and "interference" are so tied together.

In this way, "wireless monitoring" and "interference" are so tied together.


Whenever there is an unclear problem with our monitoring signals, we may consider whether it is an interference problem. Yes, in our "wireless" era, it is not an easy task to completely get rid of interference. External interference has affected our wireless transmission effect to a lesser extent. So how do we avoid interference?


Similar equipment interference


Avoid the surrounding similar equipment, or the signal interference of the same equipment. The signal source of such an interference signal may be a normal signal source in our system, and the receiving end may not receive the signal or receive the same signal due to the same frequency or similar, making the receiving terminal difficult to recognize. In this case, we can adjust the frequency of the wireless device, choose a clean channel, or change the location of the wireless device transmitter or receiver to open the distance between the devices.


Building interference


Buildings have a debilitating effect on the transmission of wireless signals. When a wireless signal passes through any object, its electrical frequency signal will be refracted to some extent, causing a certain change in its transmission direction, and will cause reflection and attenuation of the signal. If a metal object is encountered during propagation, the attenuation of the signal is also increased. Therefore, when selecting the installation position of the wireless device, the middle is unobstructed as much as possible, and the transmitting end is visible to the middle of the receiving end, thus avoiding the attenuation of the microwave signal, and the monitoring center can receive the high-intensity wireless signal, thereby improving Monitor the effect.


Not all devices interfere with wireless, such as mobile, Unicom towers, walkie-talkies, wireless phones, etc., which have no effect on wireless microwave devices. In the case of interference sources, we can adjust the frequency of the device or choose to install it far away from the interference source, thus greatly reducing the interference to the wireless microwave device.
