Why is the home network not good in rainy and snowy weather?

Because WiFi is essentially electromagnetic waves, clouds, fog, rain, humidity and so on. Will lead to electromagnetic wave attenuation. Wireless network belongs to microwave communication. Rainwater can absorb both ultrashort wave and microwave, but basically has no absorption effect on short wave, medium wave and long wave.

In rainy and snowy days, the humidity will slightly weaken the radio waves transmitted through the air (it can absorb this signal and weaken it), so in heavy rain or high humidity weather, the received signal may be slightly weakened, and the most direct impact is the decrease of wireless network speed, which is often called "slow network speed".

In case of heavy rain or even rainstorm, raindrops will absorb and scatter electromagnetic waves, and the signal intensity of wireless networks in the air will also be weakened.

At the same time, because the antenna feed system of the outdoor unit of the satellite station is exposed all the year round, it will inevitably be eroded and damaged by rain and snow, and maintenance personnel need to check it regularly.

Therefore, every time it rains heavily and snows heavily, it will almost bring problems to users' networks. But even so, in the case of very bad weather environment and road traffic, maintenance personnel must also strengthen maintenance.

Wireless network is a network realized by wireless communication technology.

It not only includes the global voice and data network that allows users to establish long-distance wireless connections, but also includes infrared technology and radio frequency technology optimized for short-distance wireless connections. It is very similar to the use of wired networks, but the biggest difference lies in the different transmission media. Using radio technology instead of network cable can be used as a backup of wired network.
