802.11h(TPC) is not enabled. Enabled TPC if supported, in order to extend client battery life and reduce client-induced contention.
What is TPC?
TPC, or Transmission Power Control, is a crucial mechanism in wireless networks that optimizes radio frequency (RF) management. By adjusting the transmission power of the access point, TPC enhances coverage while minimizing interference with other devices.
What is 802.11h?
802.11h is a standard designed to address interference issues in wireless communications. It enables wireless devices to effectively reduce interference through several key features: Dynamic Frequency Selection (DFS), Transmit Power Control (TPC), and Channel Switching.
Dynamic Frequency Selection (DFS): This feature detects the presence of other devices operating on the same channel. When such devices are identified, DFS automatically switches to an alternative channel to prevent interference.
Transmit Power Control (TPC): TPC works to limit the output power of RF transmissions, thereby reducing interference with nearby devices.
Channel Switching: This capability allows wireless clients to seamlessly transition to a new channel whenever the access point (AP) alters its channel.
What does 802.11h have to do with TCP?
In the context of wireless networks, 802.11h significantly enhances the performance of TCP traffic. By effectively managing radio spectrum usage through features like DFS and TPC, it reduces interference and ensures smoother data transmission.
