 Foreign media: the United States cannot decouple from China in 5g telecommunication technology


For American hawks, this is a fact that cannot be ignored. First, it allows China to collect royalties for related equipment sold in the US market, which will benefit Chinese manufacturers such as Huawei and ZTE.

However, the United States cannot simply resist 3GPP. This may further enhance Chinas influence.

As a result, the United States has recently adjusted its trade sanctions against China to ensure that American companies can cooperate with Chinese companies in 5g and other standard setting.

Looking back on the history of o-ran Alliance

This solution can improve the U.S. technology leadership, enhance competitiveness, and reduce our dependence on foreign suppliers, FCC Commissioner Geoffrey Starks said in a statement

Even if we ignore the immaturity of openran technology, these remarks seem to ignore the two main obstacles to the decoupling of American and Chinese technologies: Chinese companies are involved in the development of openran standards; in fact, openran is an accessory of 3GPP, rather than an independent system.

The former fact should be obvious to anyone who knows about openran.

The o-ran alliance was announced at mwc2018, which is mainly formed by the merger of two existing operators led associations. One of them is x-ranforum, which is dominated by American companies, of which at & T is its largest member. The other is the c-ran alliance, a Chinese organization, of which China Mobile is the biggest supporter.

Although it is certainly impossible to imagine such cooperation between China and the United States, such cooperation has embedded Chinas proprietary technology into the weapons that the US government now wants to use against China.

Picocom is a Chinese start-up and a member of the o-ran alliance. Peter Claydon, President of bicocci, said the conflict had not disappeared. Part of the irony of o-ran now is that a lot of it came from China Mobile in the first place, he said

However, it is even more difficult to understand the ownership of o-ran technology than 3GPP technology.

One of the most important technologies of o-ran is the new interface between RF and baseband. This forward will replace the old industry specification known as CPRI, which forces operators to buy RF and baseband products from the same device manufacturer.

John Baker said the o-ran alternative solution, developed by at & T, Cisco, mavenir, Nokia, Samsung and Verizon, enables operators to use different RF and baseband suppliers. There are no Chinese manufacturers.

It is incredible, however, that the c-ran alliance has not made any recommendations.

Fundamentally, they want to deploy o-ran. He said and pointed out that an o-ran connectivity conference is planned to be held in Beijing in September.

Unable to get rid of 3GPP

Even if the U.S. does have the upper hand in o-ran, it cannot avoid 3GPP or existing technologies. What o-ran essentially does is fill in gaps in which the mobile interface is either incomplete or unavailable.

O-ran still relies on the 3GPP process and the overall end-to-end specification to make sure everything matches and works, says John Baker

In CPRI alone, Huawei is one of the four major patent owners, and the other three are Ericsson, Nokia and NEC. NEC is a recovery force in the equipment market.

This reliance on 3GPP poses another potential problem for openran - there is a risk that openran opponents with mobile technology patents will try to use patents to block openran transactions.

However, John Baker believes that the possibility is remote. He pointed out that major patent owners, including Ericsson, NEC and Nokia, have now joined the o-ran alliance. Moreover, this strategy may also be strongly opposed by operators.

In any case, the U.S. government seems to turn a blind eye to Peter Claydons irony.. Even if the United States intends to develop its own products from scratch, they will still use Chinese patents, he said

One well meaning explanation is that Americas top priority today is to dismantle Chinese equipment and cultivate American alternatives for Chinese suppliers.

To be more serious, these officials are missing out on the bigger picture.
