IEEE modes - Different IEEE 802 modes for different types of area networks.
Channel width - select the maximum width of the operating radio channel. The device 5 GHz radio
device typically supports channel widths of 20 MHz, 40 MHz and 80 MHz; the 2.4 GHz radio typically
supports channel widths of 20 MHz and 40 MHz. When you select higher channel width, the device
will be able to overlap its channels - this may increase the data transfer rate.
Channel - select the channel at which the access point will be operating. Auto channel selection is the
default option. When automatic channel selection is enabled, the board will attempt to choose the best
channel, based on the surrounding network usage and interference. Channel selection can influence
the WiFi coverage and performance. You can also select multiple channels on which the board will
operate.
Tx power (dBm) - the unit's transmitting power at which the device will transmit the data. Changing
this option will affect the strength of the signal that radio produces during transmission. The higher
Tx power may extend the operation range of the wireless network, but lowering Tx power reduces
interferences, especially when other wireless devices operate nearby. The maximum transmit power
permitted varies by country in which the device is operating.
Station mode
When you select a Station wireless mode, your board itself can act as a wireless client, so it can
connect to other wireless network SSIDs (access points).
The Station wireless radio interface must be added as a member to one of the networks created on
this AP3400 board, either LAN or WAN:
– If you add the Station interface to a WAN network, then it will act similarly to an ethernet cable
