Drawback: It will reduce throughput proportional to the channel size reduction.
So just as turbo mode (40MHz) increases possible speeds by 2x, half specrtrum
channel (10MHz), will decrease possible speeds by 2x.
Channel Shifting: option enables the special channels which have the frequency
offset from the standard 802.11b/g and 802.11a channels. This is a proprietary Ubiquiti
developed feature. While 802.11 networks have standard channels such as Channel 1
(2412MHz), Channel 2 (2417MHz), etc. spaced every 5MHz apart; channel shifting will
allow operation of new non-802.11 channels offset from the standard channels. The
benefits of this are private networking and inherent security. Using channel-shifting,
networks can instantly become invisible to the millions of wifi devices in the world.
Channel: select the wireless channel while operating in
Access Point
mode. Multiple
frequency channels are available to avoid interference between nearby access points.
The channel list varies depending on the selected country code, IEEE 802.11 mode,
Channel Spectrum Width and Channel Shifting option.
Output Power: This will configure the maximum average transmit output power (in
dBm) of the wireless device. The output power at which wireless module transmits
data can be specified using the slider. When entering output power value manually,
the slider position will change according to the entered value. The transmit power level
that is actually used is limited to the maximum value allowed by your country's
regulatory agency. Note: In case of NanoStation, this is the output power delivered to
the internal Antennas.
Obey regulatory power box must be always checked. While checked transmit output
power will be tuned according to the regulations of the selected country.
Data Rate: This defines the data rate (in Mbps) at which the device should transmit
wireless packets. If the Auto check box is enabled, then the
rate algorithm
will select
the best data rate depending on the link quality conditions. If a data rate below
54Mbps is selected while the
Auto
rate selection is enabled, then the selected data rate
will become the maximum data rate that can be used. Use
Auto
option if you are
having trouble getting connected or losing data at a higher rate. In this case the lower
data rates will be used by device automatically.
