It is known that wireless bridges are used outdoors and are rarely used outdoors unless they are monitored by elevators. Since it is outdoors, the impact of the environment on wireless bridges is very large and manifested in the following aspects. 1, covering There are various buildings, trees and other things outdoors. In practical applications of wireless bridges, it is inevitable that obstacles will be encountered. The wireless bridge transmits signals through electromagnetic waves. Once these obstacles are encountered, the signal is greatly reduced, which greatly affects the transmission effect. So be sure to avoid obstructions when deploying. Before the transmitting end and the receiving end are preferably visible and without any shielding, good transmission effect can be guaranteed. Therefore, when purchasing a wireless network bridge, it must be combined with specific environmental conditions. It must be clearly stated to the person selling it, so as to avoid the use of a wireless bridge that cannot be used, which is troublesome. In this regard, I once suffered from a loss when selecting the Fengrunda Wireless Bridge. The election was not very suitable for the on-site environment and was finally replaced in exchange for it. 2, frequency interference The wireless bridge works in the 2.4G or 5.8G band. In our lives, there are many devices in the same band, especially the 2.4G band. In an environment full of 2.4G frequencies, if you also use a 2.4G wireless bridge, it is tantamount to digging your own grave. Because of the strong co-channel interference, the wavelengths of different devices can cancel each other and cannot continue to transmit. But not all other equipment can be removed, which requires the right choice when choosing a wireless bridge. In urban areas or where there is a lot of interference, try to use a 5.8G wireless bridge. In a relatively clean environment, you can use a 2.4G wireless bridge. 3, the weather The weather also has a certain impact on the transmission of wireless bridges, such as rain, scorching sun, thunderstorms, strong winds, etc. If the quality of the wireless bridge itself is not qualified, it cannot withstand the harsh outdoor weather “tormentâ€. It rains: If the wireless bridge works fine, it is extremely waterproof and will not have any problems when it rains. However, in addition to the equipment itself, such places as the net mouth should be sealed to prevent moisture from penetrating into the interior. Exposure: The high temperature and the hot sun test the material of the wireless bridge. If the material is not good, it will soon be aged and softened. This will not only affect the data transmission, but may also have security risks. Lightning protection: If you use a wireless bridge lightning protection outdoors is essential, not only do you need to do a good job of preventing lightning, direct lightning must also be handled well, especially in the environment where the installation position is relatively high. Ray's defense. Wind speed: The wind speed of the wireless bridge works normally: 240 Km/h, which can resist winds over 17 levels. The impact of wind speed on the wireless bridge will occur when the installation is not secure, so be sure to install it firmly. The columns and brackets used must be fixed.

1. Size: Usually the size is the size of a mobile phone.
2. Battery life: It is required to have at least 1-2 hours or more of battery life without power connection. In addition, its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling. Can be carried with you (it can be put into a pocket, the screen can be projected to 40-50 inches or more, so sometimes we also call it a pico projector or a pocket projector.)
