      Why is the power plant/reservoir/drone wireless module long-distance WiFi module solution so popular? In modern wireless transmission engineering, wireless modules are the most widely used. It can be seen in monitoring projects in many fields. There are many wireless devices on the market. Why are long-distance WiFi modules so popular? Let us take you to find out.

      Why Power Plant/Reservoir/UAV Wireless Module Long-Range WiFi Module Solutions Are So Popular

      1. The wireless module has strong anti-interference ability


      The long-distance WiFi module uses electromagnetic waves as the carrier for transmission, so it is impossible to predict whether there is interference of clutter in the transmission environment. Signal interference is very common in practical applications. In order to overcome wireless interference, we not only need to avoid large interference in the environment, but also need to make efforts from the anti-interference of the module itself, such as video coding algorithm: using an efficient video compression ratio to achieve the same quality of video data, with better reduce the possibility of file interference; improve the error correction capability of video transmission, and provide recovery algorithms for transmitted erroneous data.


      2. Long-distance WiFi module has high net bandwidth


      Traditional analog wireless transmission equipment can only use point-to-point mode to transmit video signals, and cannot achieve multiple transmissions at all. The long-distance WiFi module solution has very obvious advantages in this regard. It can concentrate multiple camera signals, and then use point-to-point transmission, or multiple transmissions. The use is very flexible, and the net bandwidth of the long-distance WiFi module is also very high. As long as there are professional and technical personnel to debug, the high-bandwidth transmission of the wireless bridge can be fully guaranteed.


      However, not all wireless bridges have high net bandwidth. After all, many device makers on the market are cheating with the slogan of a wireless network bridge. In fact, many accessories such as the internal chips of the seemingly overbearing wireless network bridge cannot reach the outdoor transmission quality. This is why wireless is classified into consumer grade, carrier grade and industrial grade. Therefore, users must choose a strong and qualified company like us when purchasing wireless network modules.


      3. The long-distance WiFi module solution has good security


      As we all know, the long-distance WiFi module adopts the wireless open transmission method. While open transport makes the use of wireless bridges more flexible, there are a number of drawbacks. Due to the natural magnification of data, data transmitted over wireless networks is destined to be intercepted, which poses a huge risk to sensitive video data. By intercepting the wireless signal, it is relatively easy to decipher the content of the wireless transmission if a competitor or malicious intent takes an illegal approach. Therefore, the application of the secure wireless video surveillance system not only ensures the long-term trouble-free operation of the surveillance equipment, but also the security of video data in the wireless transmission chain is also a part that cannot be ignored. The video transmission must have the anti-theft function, and the video data must have encryption means such as anti-tampering function to ensure the validity and security of the final data.


      What signals can the long-distance WiFi module transmit? As we all know, a wireless module is a kind of signal used to transmit signals, which consists of a sending device end and a receiving end. But signal is an umbrella term that can contain many types of signals. Which signals can be transmitted in practical applications? let us see.


      1. Transmission of audio and video


      The long-distance WiFi module can not only transmit audio signals, but also realize two-way voice intercom. If the front-end network camera and the back-end network hard disk recorder have audio input and output ports, they can be transmitted directly through the wireless network without signal conversion. If the audio is transmitted separately, it needs to be converted to a network interface instead of a network interface, and then the front-end video signal is concentrated through a switch.


      2. Transfer data


      In some special environments, to use wireless network to transmit data, the data interface must be converted into a network interface through hardware for normal transmission. The long-distance WiFi module can realize two-way data transmission.


      3. Transmission of network signals


      In some places, we need to achieve wireless transmission, but also need to achieve wireless coverage, so we do not need network signal transmission equipment at this time. We can access the wireless transmission video receiving end through the switch, and return the network signal of the front end.


      4. Wireless bridge transmission switch


      Generally speaking, in places such as drones, power plants, reservoirs, pumping stations, etc., the switching values of some devices need to be remotely controlled through long-distance WiFi modules. At this point, we need to convert the switching value into a network signal, and then transmit it through the wireless network.


      5. The wireless module transmits the PTZ control signal


      In the wireless transmission system, the cloud platform in the tennis machine remotely controls its rotation and movement direction through the control system. The cloud platform control signal in the wireless transmission system also needs to be transmitted through the wireless bridge, and also requires reverse data transmission. The wireless module is used to transmit signals, and there is no need to use a separate transmission device for control. Connect the front-end signal to the wireless network to realize remote cloud platform control.
