The report said that the intermediate frequency band is the most common 5g network in the world, but it has not been widely built in the United States. The 5g coverage of 50 states in the United States advertised by American operators refers to the low frequency band. It is faster than 4G network, but it is the slowest 5g network.
According to some data, so far, the download speed of 5g network in the United States is only 1.8 times faster than that of 4G network. In other countries that use if frequency 5g networks, the speed can be five times that of 4G.
U.S. media pointed out that if the U.S. people only have low-frequency available, then they are not worth upgrading to 5g mobile phones, because the low-frequency 5g network speed is not much faster than 4G.
