Dynamic Transmit Power Control for Wireless Interference

The patent dynamically adjusts the maximum transmit power parameter for high-power wireless devices based on the number of connected devices and network conditions. When the number of high-power devices exceeds a threshold, the system reduces their maximum transmit power from the high-power class level (e.g., +26 dBm) to a lower level (e.g., +23 dBm), thereby reducing interference to low-power devices while maintaining adequate throughput through controlled power adaptation.

The patent implements a feedback mechanism where the access node continuously monitors the number of connected high-power wireless devices and their impact on standard-powered devices. Based on this feedback, the system dynamically adjusts the maximum transmit power configuration for high-power devices, reducing power when interference thresholds are exceeded and restoring power when conditions permit, thereby maintaining network capacity while protecting standard-powered devices from harmful interference.

The patent transforms the static power class configuration into a dynamic system where the maximum allowable transmit power is no longer fixed but adapts in real-time based on network conditions. The access node dynamically adjusts the maximum transmit power parameter for high-power devices based on the number of connected devices, interference levels, and network load, while still respecting the device's power class capabilities. This dynamic approach maintains device compatibility through standardized power class definitions while adding the flexibility to adapt power levels to varying network conditions.
