DFS / TPC
This section displays information about the Dynamic Frequency Selection (DFS)
and Transmit Power Control (TPC) Status information and configuration.
DFS/TPC is required for operation in certain frequency ranges as mandated by
local regulation. If the device detects radar on a give channel it must stop
transmitting and flag the channel as unusable for 30 minutes. The radio then
selects a new channel from the available channel list. The radio must scan this
channel for 60 seconds before starting to transmit. If radar is detected on the new
channel it must repeat the previous steps until it finds a free channel. If all the
channels show radar events the radio will have to wait for the 30 minute timeout to
try the channels again. As such, if you are in an area with radar events channels
requiring DFS/TPC are not recommended for backhaul use.
DFS Status:
Displays operational status.
Available Channels:
Displays the number of channels available for the

Disabled Channels:
Displays the number of channels disabled by radar
events.
Channel List:
Shows the channels that have seen radar events, the
number of radar events, the time since the last event,
and the current status of the channel.
Manual:
Enables manual power control if allowed by local
regulations.
Automatic:
Allows the radio to automatically select the best
transmit power.
Do not jump outside of
current band:
Restricts the radio to stay within channels in the
current band when scanning for available channels.
