5G millimeter wave, which is criticized by netizens, is being established by more than 100 operators and more than 150 networks around the world.

As we all know, after entering 5G, two frequencies have been written into the 5G standard by 3GPP, one is Sub-6 and the other is millimeter wave. Sub-6 refers to the spectrum from 450MHz to 6GHz, while millimeter wave refers to the spectrum from 24.25GHz to 52.6GHz.

Since the three major domestic operators mainly use Sub-6, and in the beginning, only the United States used millimeter waves, and there have been rumors that the reason why the United States does not use Sub-6 is because Sub-6 has been used by the military. Occupied.

As a result, many netizens have been complaining about millimeter waves based on the principle of "we must oppose what the United States uses, and we must support what the United States opposes." They think it is a joke.

Especially when some professionals pointed out that millimeter waves have short distances and fast attenuation due to their high frequency, and that a leaf or a wall may be able to block the signal, everyone even complained and ridiculed.

Although other professionals later said that millimeter waves have advantages, such as fast speed, good directionality, low delay, etc., Sub-6 is the best when combined with millimeter waves, but netizens are I didn't listen and thought it was a way to clear ground for the United States.

Today we will not talk about the issue of washing or not. We will just talk about the current global 5G status, and everyone will understand whether millimeter waves are useful.

As of June 2021, 169 operators in 70 countries around the world have released 5G. Together with the operators that are investing in 5G, the overall number has exceeded 400. This number Already a lot.

From the perspective of the global 5G landscape, it can be divided into three major areas. The first is Europe, Asia-Pacific, and North America, which are regions with rapid 5G development and have basically completed the commercial use of 5G networks; the second is that The second is South Asia, Eastern Europe, North Africa, and Central and South America, which are still undergoing 5G deployment and pre-commercial use; the third is sub-Saharan Africa, where 5G is still blank in most areas, and some countries and regions even have 4G.

From the perspective of the spectrum used by 5G globally, Sub-6 is definitely the mainstream. As shown in the figure above, n77 and 78, two but also typical Sub-6 spectrum resources, are used the most. There are Nearly 100 such networks have been deployed, and more than 240 have been evaluated and tested.

Ranked second is the millimeter wave band, such as n257/n258/n261. There are already more than 20 5G networks using millimeter wave in the world, and with those under evaluation and testing, the number reaches more than 150, ranking second.

In fact, even in China, the three major operators started millimeter wave technology research and experiments in 2017. According to the operators’ deployment plans, millimeter wave has been commercially available in China in the past two years. The landing is basically a sure thing.

It can be seen that everyone should not be biased against millimeter waves. If you think that millimeter waves are useless, it is really a bit extreme. In the future, all countries and operators will definitely be Sub-6 Along with millimeter wave, that is the best choice.
