The important thing to consider is WHO is in control of implementing 5G. There was a point in time Huawei (world's No. 1 telecom supplier and No. 2 phone manufacturer) wanted to implement 5G infrastructure in the U.S. however that will not be the case here in the U.S.
Huawei= CHINA
Question, who IS implementing 5G infrastructure?world's No. 1 telecom supplier and No. 2 phone manufacturer
