It is said that 5G has been commercially available in China for more than a year, and users have developed rapidly, and more and more people have switched to 5G mobile phones and 5G packages. That being the case, we can't help but ask: What is the internet speed?
1. Has the vision of 5G been realized?
According to the statistics of the China Academy of Information and Communications Technology in 2020, the average 5G download rate of the three major operators is between 500 and 600 Mbps, which is more than 10 times that of 4G.
But don't forget that although 5G users are growing fast, the number of users is still far smaller than 4G. Once more and more people grab bandwidth from you, the average speed will drop. Besides, is 5G just the faster 4G?
After experiencing the birth of infinite hope, the budding of forging ahead, and the rapid development of blood, 5G, do you still remember your original dream?
In your dream, your journey is the sea of stars where everything is interconnected.
In your vision, there are extreme mobile broadband, massive machine interconnection, and ultra-high reliability and low-latency communications.
Dare to ask, how much have been achieved?
Has the peak rate of 20Gbps been achieved?
Has the industry application with a delay of less than 1ms been realized?
How is the development of the Internet of Things connected to a large number of machines?
In fact, everyone is very clear in their hearts that the revolution has not yet succeeded, comrades still need to work hard!
Therefore, countless eyes of hope are cast on a virgin land that has yet to be reclaimed: millimeter waves.
This virgin land has always been a barren land in the 1G to 4G era, and at the same time it is fertile, but it is also full of thorns.
It is the goal of 5G to conquer. Only millimeter waves can lead 5G to reach the established peak rate, and at the same time, it is irreplaceable in terms of reducing latency.
2. The advantages of 5G millimeter wave are outstanding
The millimeter wave spectrum is extremely rich Millimeter wave generally refers to the radio frequency spectrum in the range of 30GHz to 300GHz.
Compared with the traditional wireless frequency spectrum, the frequency is much higher, so it is also called high frequency.
According to the formula of "wavelength = speed of light ÷ frequency" of electromagnetic waves, the wavelength of this section of the spectrum is between 1 mm and 10 mm, which is the origin of "millimeter waves".
The actual millimeter wave used in 5G is between 24 GHz and 100 GHz.
