American 5g open ran suffered another major setback, and its attempt to counter China's 5g technology has failed

Recently, famous in the United States Open RAN supplier Parallel Wireless Mass layoffs , At least 50% of the staff will be laid off , Previously, American operators have publicly complained that 5G ORAN The equipment is unreliable and too expensive, so it is planned to dismantle such 5G equipment , Now even the suppliers can't survive , On behalf of this American plot 5G The plan of technological voice has basically failed .

At present, the world is advancing 5G commercial , and 5G The main contributors of patents are Huawei and ZTE in China , Many communication enterprises in China have contributed 5G 40% of core patents , It ranks first among many economies in the world .

from 2G To 5G, China has successfully changed from a follower to a leader , It represents China's great progress in mobile communication technology , With China's increasing voice in mobile communication technology , China has also cultivated its own perfect mobile communication industry chain , chip 、 equipment 、 Mobile phones have formed a complete industrial chain .

by comparison , The United States has a declining voice in the field of global mobile communication technology , In order to gain more say , The United States in 5G Technically, it is first proposed 5G Millimeter wave technology , But because 5G Millimeter wave technology is not mature enough and the cost is too high , As a result, there are only limited in the United States and South America 5 Operators adopt 5G Millimeter wave technology , Now the operators in the United States have turned back 5G Centimeter wave and even low frequency 5G technology ,5G Millimeter wave technology is only used by American operators to supplement fixed line broadband .

5G After the basic failure of millimeter wave technology , The United States has proposed 5G Open RAN standard , This is because there are no communication equipment manufacturers in the United States , So I hope to use the United States Intel Dominant server chip business , To break the current supply by communication equipment manufacturers 5G The pattern of equipment , However, US operators say 5G Open RAN The equipment is too unreliable and the cost is too high, so it is planned to dismantle the deployment equipment , Now 5G Open RAN The suppliers suffered heavy losses and laid off workers on a large scale , And let the US plot suffer a setback .

The United States 5G Open RAN Frustration is actually doomed , Because of the present 5G The network is extremely complex , Because it uses a wider spectrum , Therefore, many complex RF units are used , allegedly 5G The number of antennas is 4G Of 1-2 times , And different markets have different spectrum , For example, in China, in addition to global 3.5GHz Out of band , also 2.6GHz、4.9GHz, It increased again in the second half of last year 700MHz Frequency band , This leads to 5G The number of antennas in the base station is further doubled .

At the same time, the current mobile communication network still has 4G、5G Network co-existence , There are even 2G、3G、4G、5G The phenomenon of network coexistence , As a result, the construction and optimization of mobile communication network has become a highly complex project . Such complex system engineering , It requires equipment manufacturers to have a very high level of Technology , Ensure that so many devices are reliable enough to operate together , Professional enterprises are needed to provide professional services .

In fact, from 3G since , European operators gradually reduce their network operation and maintenance work , The equipment supplier is responsible for this kind of work , Because the equipment manufacturer is more familiar with all parts of the equipment , I also have more experience in network equipment optimization , Huawei, a Chinese equipment supplier, is widely welcomed by European operators because it can provide high-quality operation and maintenance services , The number of employees in Huawei is several times that of Ericsson or Nokia , In terms of O & M service response, it is far better than Ericsson and Nokia .

Facing the complex situation of mobile communication network , However, the United States is trying to make the mobile communication equipment business Intel And so on to provide the operators with 5G The Internet , These enterprises have no experience and technology in mobile communication equipment operation and maintenance , In such a complex environment, it is naturally impossible to provide reliable services for operators , Operator abandonment 5G Open RAN The equipment is reasonable .

The United States' repeated attempts to violate market rules are for its own interests , However, the reality hit the face again and again , This shows that even if it is stronger than the United States, it cannot go against the market and technological development trends , The US technology industry should still recognize the market trend , Only by cooperating with all industries around the world can we truly achieve win-win , Otherwise, you will only suffer setbacks again and again .
