As the world toward the intelligent direction of deepening the development of society as a whole ecosystems dependent on networking technology and communications technologies have become increasingly demanding. Industrial router as the connection of different network paths channel, by providing a more solid and stable network transmission signal for each field and 5 G integration and development technology, and now industrial router has been widely used in smart grid, intelligent transportation, smart home and intelligent building field, 2.4G and 5G is divided into two modes on the connecting band, so how should we distinguish between 2.4G and 5G industrial router industrial router? Features 5G industrial router What?
4G and 5G comparison:
The advantage of 4G: transmission distance, anti-attenuation ability, through the wall is very good. Disadvantages are: industrial, scientific, medical field free band, life on many devices in this frequency band, such as Bluetooth, microwave ovens, remote controls, etc., resulting in crowded 2.4G channel.
5G advantages of: providing more bandwidth, data throughput may be enhanced, less disruption 5G band, faster transmission speed. The disadvantages are: poor penetration, covering a short distance, and now most of the smart device still supports 2.4G, does not support the 5G.
5G Industrial Router
4G, 5G speed comparison
2.4G single antenna, is 40MHZ (router disposed 20M, 40M bandwidth) bandwidth, a bandwidth of up to 150M to. 2.4G is more than double antenna 300M.
5GB single antenna, 40MHZ, the highest able to 300M bandwidth, 5G support VHT80, in this mode to achieve a single day of 5G 433M bandwidth. If the available bandwidth performance 866M at 80MHZ.
Why 5G industrial router through the wall effect signal worse than 2.4G industrial router signal?
Is the same distance from the router, 5G 2.4G signal is relatively weak signal, which is determined by the physical characteristics of electromagnetic wave: a wavelength longer the less attenuation, also continues to propagate around obstacles more easily. 5G signal of the high frequency, wave length and the low frequency signal 2.4G, long wavelength, the attenuation greater obstacle passes through 5G signal, through the wall than 2.4G weak signal, all dual-band wireless routers exist such a situation.
Note: The following is a 2.4G and 5.8G loss formula propagating in free space (where F is the frequency in units of MHz; D is the distance, in units of km)
Wireless electromagnetic waves in free space attenuation equation: L = 32.5 + 20lgF + 20lgD.
2.4G band attenuation formula: L1 = 100 + 20lgD;
5.8G band attenuation formula: L2 = 108 + 20lgD.
As can be seen above formula attenuated phase 5.8G to 2.4G is higher, corresponding to the distance covered by the smaller.
Features 5G industrial router
- Good anti-jamming
Since 5G band signal energy is large, but the coverage is weak, which is a large room coverage, through walls great influence, it led to a small mutual interference between the router and router used with existing 2.4G signal different frequency bands, the signal is very stable.
- Transmission speed
If the home is Fast broadband router after opening the 5G, phone connection speed test software, excluding cable signal attenuation and wireless signal attenuation, test out the download speeds can reach more than 10 megabytes per second. And I measured out the 2.4G signal to 4 to 6 trillion. Of course, there is the relationship with the family of broadband. If more than 200 megabytes of broadband, we believe 5G will be faster, while 2.4G signal has to reach a peak.
- Required by the receiving apparatus transmitting
For instance, some old models of mobile phones and laptop wireless receiving device does not support the 5G, and that even if the router opened 5G, you also can not find it signals the need to purchase a dedicated wireless card.
We all know that times will inevitably continue to move forward eliminate old transaction does not meet the social trend, it is inevitable guidelines survival of the fittest. Billion of things that with the rapid development of technology, intelligent communication field also continues to introduce new, energized by the 5G 5G band router industry compared to traditional routers in transmission speed, transmission quality and equipment have a new form of requirements more in line with the smart device development needs of communication system in the era of things. Today, the industrial router already has a more loyal applications and application scenarios in the future with the advancement of technology to enhance communication and networking technology, 5G industrial router will break out even stronger market functions.
