neville Ray FCC 4G vs 5G smaller 230No telecom engineer will be surprised that Peter Clarke recorded 344 Mbps downloads on 4G LTE to a BT Huawei tower. LTE has been testing over 1 gigabit in the lab and hundreds of megabits in the field for two years. 

T-Mobile CTO Neville Ray says that in theory the difference with NR should be 19% to 50%. In practice, I would expect less. If Peter had a 5G phone, the same spectrum at most would deliver about 480 Mbps. Huawei has improved 4G however, and the difference should be half.

Only salesman, politicians, and pundits believe ten times improvements from 5G. Interesting video of the actual test below
