The company's telecommunications company (Three UK) has been using Nokia to provide related 3G equipment, while Samsung is its 4G service equipment supplier. However, after some consideration, Three UK decided that Huawei will become its future 5G service partner.

11. Analyst: 5G fixed wireless will become the biggest threat to fixed network operators

In August 2018, according to Cowan's analysis of emerging technologies, high-speed fixed 5G services will become a bully to steal some of the CATV operators' lunch funds. According to En, Verizon and T-Mobile USA will be the biggest threat to CATV operators' lucrative broadband business.

But Richard also said that "the measures to deal with information security are still necessary."

8. Power 5G Verizon announces major restructuring

In early November 2018, Verizon announced that it would reorganize its business unit into consumer, commercial and Verizon media groups. Previously, the operating structure of the largest wireless carrier in the United States was divided into two parts, wireless and wired, including its Fios Internet and video products. The company's CEO, Hans Vestberg, said in a statement that these changes will take effect on January 1, 2019 and will "optimize us as a growth opportunity for leaders in the 5G era."

7. 5G terminal release schedule for 2018 and beyond

1. Ericsson VS Nokia: 5G battle

At the beginning of August 2018, when the second quarter results were announced, Nokia CEO Rajeev Suri had to convince investors that the company is still in a stable state in the face of a crisis in profits. However, the contrast between Nokia and Ericsson is obvious. Ericsson announced in its second quarter results that it achieved operating profit for the first time in seven quarters. The great advantage of Ericsson is still in the field of wireless access networks (RAN). With the new Ericsson radio system, which is an RAN platform that already accounts for 84% of Ericsson's total RAN sales, Ericsson has already received some large orders. Especially in Germany, it has replaced Nokia as the RAN supplier of Deutsche Telekom. The increase in R&D spending has already made this technology a great benefit for the company, making Ericsson more competitive in equipment tendering. In the non-RAN field, Nokia's advantages are more obvious, and this has a great impact on the competition between the two parties, because for service providers who want to buy RAN products and management tools from the same supplier, Nokia May be a better choice.
