Reasons for Good Wall Penetration Performance of 5G Cellular Routers

With the further development of the world in the direction of intellectualization, the whole social ecosystem is becoming more and more dependent on the Internet of Things technology and communication technology. Industrial routers, as a path channel connecting different networks, provide more solid and stable network transmission signals for various fields through the integration and development of 5G technology. Nowadays, industrial routers have been widely used in smart grids, smart transportation, smart home, smart building, and other fields, and can be divided into 2.4G and 5G modes in the connection frequency band. So how should we distinguish between 2.4G industrial routers and 5G cellular routers? What are the characteristics of 5G cellular routers?

Comparison of 4G and 5G:

Advantages of 4G: long transmission distance, strong anti-attenuation ability, and good ability to penetrate walls. The disadvantage is that the free frequency band in the industrial, scientific, and medical fields is used by many devices in life, such as Bluetooth, microwave ovens, remote controls, etc., which leads to the congestion of 2.4G channels.

Advantages of 5G: larger bandwidth, enhanced data throughput, less interference to the 5G band, and faster transmission speed. Disadvantages: poor penetration, short coverage distance, most smart devices still support 2.4G, do not support 5G.

Comparison of 4G and 5G speed

2.4G single antenna, for the bandwidth of 40MHZ (the router can set the bandwidth of 20m and 40m), the maximum bandwidth is 150m. Over dual antenna 2.4G is 300m.

5GB single antenna, 40MHZ, up to 300m bandwidth, while 5G supports VHT80, in which 5G can reach 433m bandwidth in a single day. It can provide 866M bandwidth performance at 80MHZ.

Why is the wall-penetrating effect of a 5G cellular router signal worse than that of a 2.4G industrial router signal?

Fig.3

At the same distance from the router, the 5G signal is weaker than the 2.4G signal, which is determined by the physical characteristics of electromagnetic waves: the longer the wavelength, the less attenuation, and the easier it is to continue to propagate around obstacles.5G signal have high frequency and short wavelength, while 2.4G signal has low frequency and long wavelength, so the attenuation of 5G signal is greater when it passes through obstacles, and its ability to penetrate walls is weaker than that of 2.4G signal, which exists in all dual-band wireless routers.

Note that the following is the loss formula for 2.4G and 5.8G propagation in free space (where F is the frequency in MHz; D is the distance in km)

The attenuation formula of a radio wave in free space: L = 32.5 + 20 lgF + 20lgD.

Attenuation formula of 2.4G frequency band: L1 = 100 + 20 lgD;

Attenuation formula of 5.8G band: L2 = 108 + 20 lgD.

From the above formula, it can be seen that the attenuation of 5.8G is higher than that of 2.4G, and the corresponding coverage distance is smaller.

Features of 5G cellular Router

And that anti-interference performance is good

Because the signal energy of the 5G frequency band is large, but the coverage is weak, that is, the coverage of a large room has a great impact through the wall, which leads to small interference between routers, and the frequency band used is different from the existing 2.4G router signal, so the signal is very stable.

The transmission speed is fast

If the broadband at home is 100 megabytes after the router opens 5G, the mobile phone connection is measured by speed measurement software, excluding the attenuation of network cable signal and wireless signal, the measured network speed can reach more than 10 megabytes per second. And the signal of 2.4G I measured is 4 to 6 megabytes. Of course, it has something to do with the broadband at home. If the broadband is more than 200 megabytes, it is believed that the speed of 5G will be faster, and the 2.4G signal has reached its peak.

There are requirements for receiving and transmitting equipment.

For example, some old mobile phones and laptop wireless receiving devices do not support 5G, so even if the router opens 5G, you can not find its signal, you need to buy a dedicated wireless network card.

We all know that the continuous development of the times will inevitably eliminate the old affairs that do not conform to the social trend, which is the inevitable criterion of survival of the fittest. Zhongyi Internet of Things believes that with the rapid development of science and technology, the field of intelligent communication is also constantly innovating. Compared with traditional routers, 5G Cellular Routers enabled by the 5G frequency band have new requirements in transmission speed, transmission quality, and equipment form, which are more in line with the needs of the development of intelligent devices for communication systems in the Internet of Things era. Nowadays, industrial routers have more loyal application fields and application scenarios. In the future, with the improvement of communication technology and the progress of the Internet of Things technology, 5G cellular routers will burst out with more powerful market functions.
