What obstacles affect the WiFi signal?
Once, the owner of a restaurant told Magic Box Jun that the signal in his shop was poor? He said that he got a lot of bandwidth from telecom and used well-known brands for network equipment. Why is the signal still so bad?

Box Jun followed the boss to observe on the spot. It turns out that the roof decoration of that restaurant is all decorated with metal wires. It turns out that the culprit is him, and the metal in the environment will seriously affect the radiation of the signal.

In daily life, people often ask what materials in the magic box will affect the WiFi signal. The most serious interference here is silver plating (such as mirrors) and metal. If you want good WiFi, use as little metal decoration as possible. It is true that the strong metallic atmosphere is cool and fashionable in decoration design.

In addition, reflective materials will also have a great impact on the signal. In the field test process, glass and mirror will reflect people's beauty and refract signals.

An engineer in charge of the construction of KTV WiFi told me that the decorative and sparkling glass wall in KTV is also the natural enemy of WiFi! Especially the mosaic wall made of dense glass mirrors.

Sweet potato says that fat people will block the signal. His experimental data show that the human body is affected by 2.4G wifi signal for at least 6db, and the communication rate will be reduced by 20%. The 5G signal will affect 16db or more, and the communication rate will decrease by 16db or more.

Each obstacle has a different effect on WiFi. Magic Box Jun made a simple little table.

Strict engineers don't like my lack of details. How much is less, how high is it, and what impact does it have on 2.4G and 5G? Please look at this photo.

When installing the wireless AP, the position of the AP should be as high as possible, so as to radiate downward at a higher place, reduce the obstruction of obstacles and minimize the signal blind area.

At the same time, the general rule is:

For reinforced concrete walls, partition wall covering is not recommended.

For ordinary brick walls, it is recommended that AP cover no more than 2 penetrations.

For glass walls, it is recommended that AP cover no more than 4 penetration pieces.

For wooden walls, it is recommended that AP cover no more than 6 penetrations.

For places where there are many compartments covered separately, it is recommended to place AP at the ceiling at the door of the compartment.

I hope it helps everyone, huh? What new materials are encountered in practice that may interfere with WiFi signals? Welcome to leave a message directly or send a private message to Magic Box Jun QQ33 189845 13, and look forward to exploring with you!
