      20 years of professional teaching you how to buy a WiFi module for long-distance transmission quality to win the market. The long-distance WiFi module is mainly used for outdoor long-distance audio and video transmission needs. It is the most widely used transmission equipment in the field of modern wireless transmission. However, there are various wireless modules on the market. Many equipment manufacturers are industrial grade. High Power. In the name of a long-range WiFi module, but the quality of the actual application is very different. So, in the wireless transmission needs, how to choose the module that suits your needs? The following points may help you.

      20 years of professional teaching you how to buy WiFi module long-distance transmission quality to win the market

      1. Transmission distance


      The wireless transmission distance varies according to the model and power, such as 1-10 kilometers of WiFi module long-distance transmission. In order to ensure the stable transmission effect of the system, the user must explain the actual situation of the on-site application environment when consulting the wireless module, and the equipment manufacturer can accurately recommend the appropriate wireless module.


      2. Working frequency


      The working frequency of the wireless module is 2.4G and 5.8G. Generally speaking, 2.4G wireless has good compatibility mode and good diffraction working ability. The 2.4G channel is pure, the anti-interference ability is good, the transmission distance is long, but the diffraction ability is strong. Therefore, the transmission environment must be open and unstoppable


      3. Performance stability


      The long-distance transmission performance stability of the WiFi module is also very important. If the network gets stuck for a while. For a period of time, if the line is disconnected for a period of time, it is impossible to establish reliable and stable monitoring and transmission. Wireless stability is directly related to product hardware, including chip motherboards, components, etc. Of course, the installation of the WiFi module is also very important. Only properly installed, the performance can function normally and stably.


      4. Transmission bandwidth


      There are many transmission rates for long-distance transmission of WiFi modules, ranging from 100mbps to 900mbps. The rate that needs to be selected can be determined according to the wireless transmission requirements. The user actually needs to consider the transmission performance at a specific distance, not the theoretical bandwidth data. For example, the basic theoretical transmission network bandwidth of the wireless module is 900mbps. At a distance of 2 kilometers, the bandwidth evaluation of point-to-point communication network reaches 400mbps, which can easily carry 20 150W surveillance cameras.


      5. Protection level


      Due to working outdoors, the environment such as rainy and snowy weather, typhoon, and high temperature changes, so the wireless module is required to have functions such as waterproof, dustproof, high temperature resistance, and oxidation resistance. This is also the reason why outdoor bridges should choose industrial WiFi modules for long-distance transmission. It has an industrial protection level of IP67. According to customization, we can also achieve IP68 military protection level, stable transmission in various harsh environments.


      6. Antenna


      Antennas are used to transmit and receive wireless signals and are important accessories of wireless systems. There are many kinds of antennas, including built-in antennas and external antennas, external antennas and omnidirectional antennas, and directional antennas. Omnidirectional antennas are used for close-range coverage and transmission. A directional antenna for long-distance transmission should be selected. In the case of the same power, the larger the antenna gain, the longer the wireless transmission distance.


      7. Power supply method


      The long-distance transmission of the WiFi module is generally used in wild environments such as forests, mountains, reservoirs, and oil fields. Power supply is also a problem that must be considered. The commonly used power supply method is POE or solar energy.


      In the wireless world, our reputation is already known to most people in the industry. Yes, we are a technology company with 20 years of industry experience, focusing on the research and development and application of long-distance transmission of industrial high-end WiFi modules. The product has high and stable transmission performance and industrial level. The quality of military transmission makes the brand deeply rooted in people's hearts and has won unanimous praise from the market. So, what makes the WiFi module have such good quality over long distances? Let me take you to meet me.


      1. High quality control requirements


      The remote module of each WiFi module must pass the electromagnetic vibration test bench (simulate the actual use environment and test the safety of product use); high and low temperature test box (test the working state of the product in high and low temperature environment); intelligent salt spray test Test box (to detect the corrosion resistance of the product to salt spray); spectrum analyzer (to detect the transmission frequency of the product when in use) and other tests.


      2. Strong waterproof performance.


      Our wireless module has been in the water tank for two days and it is still intact after two days. The unique waterproof plug design allows our wireless to be IP68 waterproof and certified by the National Radio Regulatory Commission.


      3. Each product undergoes 12 months of actual testing


      The long-distance WiFi module should be tested on-site for 12 months before sale to ensure the stable transmission of the product in special environments such as low temperature, high salinity, and underground. Otherwise, data transmission may be unstable or interrupted during use, just like ordinary wireless.


      With its industrial wireless transmission quality and professional services, it has won the trust of all walks of life. Although the wireless module has such a good quality assurance, it has been consistent in the past 20 years, and the goal has never changed. Green, humanities and science and technology are the direction of continuous efforts. In the future, we will focus on developing talent development strategies, adhere to the principles of sincerity, persistence, and win-win cooperation, and strive to provide the society with more valuable wireless communication equipment.
