Print the existing power of the link (here is a command for ath2 which is for the 5GHz Backhaul): rootRBR50: iwlist ath2 txpower. You can go as low as 1 mW, the maximum is 1 W: 1. APs can operate in Access Point mode or WIPS sensor operating mode. You can use telnet to change the transmit power of the different links. For more information on these operating modes, see AP Scan Modes.īy default, when in Access Point mode, the device selects the channel it uses automatically.
It looks for a channel with minimum Wi-Fi interference. Radio Transmit Power (dBm) Loss from Cables & Connectors (dB) + Antenna Gain (dBi) Output Power (dBm/W/mW) Lets cover each part of this calculation in turn: Radio Transmit Power This is the trickiest of the 3 parts mainly due to the fact that it can be expressed in Watts, Milliwatts or dBm. Periodic Selection - The AP surveys the radio environment at regular intervals to find the best channel and selects the new channel.Boot Time Selection - The boot interval for each AP is randomized to minimize the chance that neighbor APs select the same channel, and more thorough channel scans are performed to find the best channel.Channel selection runs at boot time to find the initial best channel and also runs periodically during regular operation to maintain optimal performance. The Selection Interval setting is configurable.

The Wi-Fi on a Mac tunes itself internally.
We recommend you use the 5 GHz radio for mesh operationįor more information.You cannot attach a Wi-Fi profile and a mesh profile to a radio at the same time.You cannot add more than one mesh profile to an AP.An AP that operates as a mesh AP cannot operate in WIPS mode or perform background scanning.If you want the AP to function as a mesh AP, you must define and add a mesh profile to a radio in the device template. The transmit power is very important part of the demodulation process, because the signal needs to be digitized at just the right level to get the maximum digital signal onto the AtoD converter. Select Configuration > Device Configuration > Device Templates.To configure radio settings in Access Point mode: see Create a Wireless Mesh Network with Manage.
