What vro does it have good wall-mounting performance? Anti-pitfall guide for wireless Routing

When you buy a wireless router, you must first identify which router has a good wall effect. In the face of a wide variety of vrouters on the market, a lot of Small and white people are looking at the complicated parameters, it is not good for sellers. It is better to teach people to fish than to teach people to fish. So I wrote a guide to identify which vrouters have good wall-crossing effects and prevent pitfalls.

The wall-crossing effect is actually the size of the wireless coverage. The wireless coverage is mainly affected by the wireless transmission power, gain, frequency band, and wall material and thickness in the environment.

Wireless transmit power

The effect of a router passing through a wall is good or bad, which is largely related to the router's wireless transmit power. In general, the higher the infinite transmit power, the better the wall penetration effect. However, the State has explicitly stipulated that the transmit power of a wireless router should not exceed 100 mW. The electromagnetic radiation emitted by a router exceeding this value will cause damage to human brain nerves. Some bad merchants publicize that the vrouters in his family have good wall-mounting effects, such as false propaganda or violation of national regulations. The signal is still terrible, and you can choose between them.

Router Antenna Gain

If you want to buy a vro with good wall effect, you need to understand the wireless gain. Theoretically, the larger the antenna gain, the farther the signal is transmitted. Common gains on the market include 3dBi, 5dBi, or 7dBi. The larger the value, the larger the gain, and the longer the propagation. However, this gain is linearly transmitted by rays. The larger the gain, the narrower the surface to be covered. Therefore, the larger the gain, the better the antenna gain.

Fortunately, smart routers (such as Xiaomi) with the "beam forming" technology have emerged on the market, enabling the transmitting end of the wireless router to perform targeted Transmission Based on the receiving end location, more intelligently and accurately transmit wireless signals to the desired places.

2.4Ghz or 5Ghz

We can hardly find that many wireless routers are in the 5G band. So what is the wall-crossing Effect of vrouters with 5g frequencies? In fact, 2g is better at penetration than 5g. The advantage of 5g is that the transmission distance is far from 2G and more information can be transmitted. If the space is large, we recommend that you purchase dual-band routers (both 2.4G and 5g ).

Wall Material and Thickness

If no wall is built in your house, it is a copper wall added with diamond cement. Sorry, it is irrelevant to you if you have a good wall effect on any vro. Two load-bearing walls, even high-power routers, the signal will be greatly reduced. When purchasing a vro, you need to know how many walls and load-bearing walls are in the house. If there are too many walls, you can add a Wi-Fi signal amplifier to expand the signal.

Don't look wrong. The "M" is not "meters "! Note! We can see on the e-commerce website that the title of M or 1200 m router is not how many meters the model can spread, but the transmission speed is 300 MB or MB. Don't be confused by this number.
