This article is about how to choose a wireless router. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Wireless transmit power:

The good or bad effect of the router through the wall is largely related to the wireless transmission power of the router. In general, the higher the infinite transmission power, the better the effect of passing through the wall. However, the state has explicitly stipulated that the transmission power of wireless routers should not exceed 100mW, and the electromagnetic radiation emitted by routers above this value will cause damage to human brain nerves. Some unscrupulous businesses advertise that their kind of router works well through the wall, either false propaganda or violation of national regulations. It is up to you to make your own choice whether you want the signal or your life.

Router antenna gain:

If you want to buy the kind of router that works well through the wall, you need to know the wireless gain. In theory, the greater the antenna gain, the farther the signal propagation. The common gains on the market are 3dBi, 5dBi or 7dBi. The larger the value, the greater the gain and the farther the propagation. However, the gain is linear, and the greater the gain, the narrower the coverage, so the greater the antenna gain, the better.

Fortunately, intelligent routers with "beamforming" technology have emerged in the market, which can enable the wireless router transmitter to transmit directionally according to the location of the receiver, and more intelligently and accurately transmit the wireless signal to the place that the user needs.

2.4Ghz band or 5Ghz band:

It is not difficult to find that many wireless routers are in the 5G band. So is it good for a router with a 5G band to walk through the wall? In fact, 2.4G is better than 5G in penetration. The advantage of 5G is that the transmission distance is longer than 2.4G, and it can transmit more information. If the space is relatively large, it is recommended to buy dual-band routers (2.4G and 5G are supported).

Wall material and thickness:

If there are no walls in your house, they are all iron walls filled with King Kong cement. I'm sorry, no matter how good the router is, it has nothing to do with you. Two load-bearing walls in one gear, even in high-power routers, the signal will be greatly attenuated. So when you buy a router, you can know how many walls and how many load-bearing walls there are in your home. If there are too many walls, the signal can be expanded by adding a wifi signal amplifier.
