Does the United States have 5g technology?

As we all know, 5G has become a new outlet for the future development of the entire technology industry. Almost all communication manufacturers are pursuing 5G-related technologies. The United States has an advantage in 5G technology on the surface, because Qualcomm The giant company that holds multiple 5G core patents is from the United States, but in fact "American 5G" is not as good as "Chinese 5G".

3GPP is currently one of the largest patent organizations in the world. Currently in 3GPP, through the continuous efforts of China’s communications industry, China, Europe, The United States has a three-legged stance.

Because China has the largest mobile market and China Mobile has many years of TDD operation experience, this time 5GNR is mainly based on TDD. my country has the most 5G project approvals and dominates the formulation of 5GNR standards. (Recommended study: PHP video tutorial)

Among the standard essential patents of 5GNR, Chinese companies also have a large number of patents written into the 5GNR standard, but American companies also have many Patents are written into standards.

Qualcomm in the United States is still the world’s largest provider of 5G baseband.

Intel has withdrawn from 5G baseband production. There are still five companies in the world that can produce 5G basebands: Qualcomm, Huawei, Samsung, MediaTek, and Spreadtrum. However, in the global mobile phone market, due to Samsung and Huawei Although 5G basebands have not been sold to the outside world, Qualcomm is still the choice of the largest number of mobile phone manufacturers in the world. Among 5G basebands, Qualcomm has the largest application volume.

In the overall equipment production and networking of 5G, only Cisco in the U.S. communications manufacturing industry can produce the core network and transmission network products required for 5G networking, and no company can produce 5G access. The network part (which is often referred to as the base station part).

In the beginning, there were actually some relatively strong companies in the United States that produced communications equipment, such as Qualcomm, Motorola, and Lucent, as well as the Canadian telecommunications industry that could barely be included in the U.S. circle. Enterprise - Nortel.

However, in order to promote its CDMA technology in the 2G era, Qualcomm sold communication equipment production to Ericsson in Europe and launched the production of mobile communication equipment;

Motorola Mobility was acquired in 2011 After Google's acquisition, it was resold to China's Lenovo. Its wireless division was acquired by Nokia Siemens at the time, which is now Nokia;

Nortel went bankrupt and had sold its 3G business to Alcatel before going bankrupt. , and the remaining wireless part was sold to Ericsson;

Lucent was acquired by Alcatel, and later Alcatel-Lucent was acquired by Nokia.

It can be seen that before you knew it, Europe's Ericsson and Nokia completed the acquisition of the wireless business of the American mobile communication equipment manufacturer.

In fact, in the mobile communications field of the United States, in order to break the European monopoly and regain its hegemony in the 1G era, IEEE once took the lead in proposing a Wimax technology in the 3G era to compete for the global mobile communications market.

The Wimax camp was very good at that time, with giants such as Intel, Motorola, Nortel, IBM, Cisco, and Alcatel-Lucent joining in. However, it still died young and killed Nortel by the way.

Generally speaking, there is no equipment manufacturer in the United States that can produce the wireless access network equipment required for 5G. Therefore, after American operators rejected China’s ZTE, Huawei and other communications companies, they can only build their own networks in the United States. The choice was between Nokia, Ericsson, and Samsung.
