## Abstract

In a wireless communication network, a wireless network core and wireless access nodes exchange user data using data rates. The wireless access nodes wirelessly exchange the data with the wireless UE over radio bands. The wireless network core determines a data rate level for the wireless UE based on the data rates. Subsequently, the wireless network core identifies a serving wireless access node and a serving radio band. The wireless network core determines a new data rate based on the data rate level and the serving radio band. The wireless network core and the serving wireless access node exchange new data using the new data rate. The serving wireless access node wirelessly exchanges the new data with the wireless UE over the serving radio band.
