The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.

For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

In a wireless network that includes mobile users (such as vehicles), the signal quality is constantly changing due to changing distances from the base station, variable attenuation factors such as passing obstructions, and beamforming in 5G and 6G networks. An automatic algorithm can compensate for transmission variations by adjusting the transmission power of the base station and/or the mobile user device, to account for the current location and motion of the mobile user device. The radio attenuation factor can be measured throughout the base station's region, and the attenuation map can be used to boost downlink power to vehicles in dead zones, while saving power in regions of good receptivity. The base station can thereby maintain the expected QoS despite motions. An AI model may be used to select the optimal power level.
