
Channel Spectrum Width: Selects whether 20 MHz or 20/40 MHz bands are used. A 40 MHz band
has twice the throughput of a 20 MHz band. A smaller bandwidth may allow more devices to be
connected. The 20/40 MHz option allows both 20 and 40 MHz bands to be used. When the
802.11ac wireless standard is used, the 20/40/80 MHz band can be selected. An 80 MHz band can
carry twice the amount of data of a 40 MHz band.

Channel: Chooses the frequency channel. The default setting of Auto may be used. For an AP, it
would select the channel with the least interference from other APs. For a station, it would
automatically select the same channel as its AP. The frequency channel may also be manually selected.
An AP and its station must have the same channel in order to communicate.


Transmit Power: Chooses the transmit power of the radio, e.g., 4 dBm, 5 dBm, 6 dBm, ... up to 26
dBm or Max. This is the total power supplied to the antennas of the radio. The maximum power also
depends on the frequency channel used.

Outdoor Channels: Limits the available channel frequency selections to 5500-5700 MHz if the
country is in the European Union (EU). Based on the EU-Rule 2005/513/EC regulation, only this
frequency band is allowed for outdoor use.

Country Code: Selects the country. Each country has its own transmit power and frequency
regulations. To ensure regulatory compliance, you must select the country where the device is
operating in. The transmit power levels for each channel are tuned accordingly.
