The actual transmission capability may be better.
- the current transmission quality of the air interface of the base station is better, or the service rate expected by the air interface is higher, and the specific data can be set to be greater than a threshold value per second, then the actual When the transmission capacity is good and the amount of data that can be transmitted per second is less than a threshold, the actual transmission capability is poor.
