The 5g cellular router is divided into 2.4G and 5G modes in the connection frequency band.So how should we distinguish between industrial routers in the 2.4G and 5G bands? What are the characteristics of industrial routers in the 5G band?
Advantages and disadvantages of 2.4G and 5G
Advantages of 2.4G frequency band: long transmission distance, strong anti-attenuation ability, and good ability to penetrate walls.The disadvantage is the free frequency band in the industrial, scientific and medical fields, which is used by many devices in life, such as Bluetooth.Microwave ovens, remote controls, etc., resulting in congestion of 2.4G channels.
Advantages of the 5G band: It provides a larger bandwidth, which can enhance the throughput of data. The 5G band is subject to less interference and has a faster transmission speed.Disadvantages: poor penetration, short coverage distance, most smart devices still support 2.4G, do not support 5G.
Comparison of 2.4G 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 does the 5g cellular router signal penetrate the wall worse than the 2.4G band industrial router signal?
At the same distance from the router, the 5G signal is weaker than the 2.4G signal.This 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 signals have high frequency and short wavelength, while 2.4G signals have low frequency and long wavelength, so the attenuation of 5G signals is greater when they pass through obstacles.The ability to penetrate walls is weaker than the 2.4G signal, which is the case with all dual-band wireless routers.
Because the signal energy of 5G band is large, but the coverage is weak, that is, the coverage of a large room, the impact of wall penetration is great.As a result, the interference between routers is small, and the frequency band used is different from that of the existing 2.4G router signal.So the signal is stable.
Relevant tests show that after the router opens 5G, the attenuation of the network cable signal and the attenuation of the wireless signal are eliminated.The measured network speed can reach more than 10 megabits per second, while the 2.4G signal is only 4-6 megabits per second.
