802.11h addresses Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC), which are crucial for minimizing interference and managing signal power in networks operating in the 5GHz band to comply with regulatory requirements. DFS allows devices to detect radar signals and switch to another channel if interference is detected, while TPC helps in adjusting the transmit power to the minimum needed to reach the intended receiver. This management aids in reducing interference with other devices and networks.
