The long-distance wifi module module has stable transmission under various challenges under long-distance transmission conditions. The wireless installation is simple and low cost, and the flexible network advantages are favored by engineers and are widely used in the wireless transmission market. Although the long-distance wifi module module has many advantages in practical applications, the wireless module needs to meet the conditions of realization to achieve long-distance transmission. So, what conditions need to be met for the long-distance transmission of the long-distance wifi module?
1. Module chip
The long-distance wifi module module chip determines its transmission performance to a large extent. Wireless is mainly used for medium and long-distance wireless transmission. Therefore, the design of wireless chips will focus on factors such as transmission distance, transmission bandwidth, and anti-interference. The high-power wireless adopts imported chips, the main frequency is 480mHz, and the built-in 32M core processor, high-speed processor and good heat dissipation performance ensure wireless long-distance transmission.
2. Antenna
Long-distance wifi module modules generally use directional antennas for long-distance bridging, so that the microwave transmission direction is relatively concentrated; generally speaking, the higher the antenna gain value, the higher the directional signal strength and the wider the coverage. Generally speaking, with the same power, the larger the antenna gain, the longer the transmission distance. However, if a high-gain antenna is used blindly, the effect of long-distance stable transmission may not be achieved. Therefore, for long-distance wifi module modules with different powers, an appropriate gain antenna must be selected, and cannot be selected blindly.
3. Receiver
When connecting over a long distance, the wireless module equipped with the antenna is also used as the receiving end, which can greatly improve the reception rate of the signal sent from the transmitting end. Adopt 802.11a/n standard, wireless transmission power up to 29dBm, support high-power transmission, built-in 18dBi dipole directional antenna, suitable for large-scale IP monitoring needs. It can transmit large-capacity data and high-definition video signals at a distance without dropping calls, freezing, or packet loss.
With the arrival of summer, outdoor temperatures are also rising. In the face of high temperature, it will affect the stable operation of many electronic devices. In addition, there are harsh environmental factors such as more rain and more lightning in summer. For this reason, many customers will worry that the long-distance wifi module will be affected by these factors. For the customer's doubts, Xiaobian tells you that there is no need to worry, because the wireless network has industrial-grade wireless transmission quality and can be used in various harsh environments. Stable transmission in the environment.
In the face of various harsh environments in summer, the long-distance wifi module module has the following advantages:
1. Anti-high temperature
The wireless module adopts imported chip high-speed processor and good heat dissipation performance to ensure stable wireless transmission in a high temperature environment of 70°.
2. Waterproof
There is a lot of heavy rain in summer. The long-distance wifi module module has been soaked in the water tank for two days. So still intact after two days. The unique waterproof plug design makes the wireless IP68 waterproof and certified by the National Radio Regulatory Commission. Therefore, there is no need to worry that the wireless module will be damaged by rain.
3. Lightning protection
Summer is the season of thunderstorms, so it is necessary to take lightning protection measures. Adopt professional POE lightning protection technology and POE lightning protection device to protect the data port and power port of the equipment from surges. In addition, there are still many places and skills to pay attention to in the installation of lightning protection, which may be the blind spot of customers' knowledge. As a professional equipment manufacturer, we will track the construction and use of wireless networks and take comprehensive lightning protection measures.
In summary, the long-distance WiFi module is not only not affected by the high temperature in summer, but also can resist the invasion of rainstorm and lightning, and ensure the stable transmission of wireless WiFi.
