Country Code
Each country has their own power level
and frequency regulations. To ensure the AirRouter HP
operates under the necessary regulatory compliance
rules, be sure to select the country where your device
will be used. The channel list, output power limits, IEEE
802.11 and Channel Spectrum Width modes will be tuned
according to the regulations of the selected country.
IEEE 802.11 Mode
Displays the radio standards used for
the AirRouter HP.
Channel Width
Displays the spectral width of the radio
channel. Supported wireless channel spectrum widths:
•
5 MHz
is the channel spectrum with the width of 5 MHz
(known as Quarter-Rate mode).
•
10 MHz
is the channel spectrum with the width of 10
MHz (known as Half-Rate mode).
•
20 MHz
is the standard channel spectrum width
(selected by default).
•
40 MHz
is the channel spectrum with the width of 40
MHz.
•
Auto 20/40MHz
(Only applicable in Station or Station
WDS mode.) It offers better compatibility.
Note:
Laptops cannot connect to the AirRouter
HP when the channel width is set to 5/10 MHz.
Some devices may not be able to connect using
the 40 MHz setting.
Channel Shifting
Enables special channels which
have the frequency offset from the standard
802.11b/g/n channels. This is a proprietary Ubiquiti
Networks- developed feature. While 802.11 networks have
standard channels spaced every 5 MHz apart, channel
shifting uses non-standard channels offset from the
standard channels. All the channels can be shifted by 5
MHz (in 802.11n) or 2 MHz (in 802.11bgn) from the default
central channel frequency. Options include Enabled and
Disabled.
Note:
Channel shifting is not compatible with
legacy products.
The benefits of this are private networking and inherent
security. Using channel-shifting, networks instantly
become invisible to the millions of Wi-Fi devices in the
world.
Frequency, MHz
(Only applicable in Access Point or
Access Point WDS mode.) 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 and Channel
Spectrum Width and Channel Shifting option.
Extension Channel
(Only applicable in Access Point or
Access Point WDS mode with 40 MHz channel width.)
Indicates the use of channel bonding that allows the
AirMax network to use two channels at once. Using
two channels improves the performance of the Wi-Fi
connection. It is automatically selected by the system.
Options include Upper Channel and Lower Channel.
Channel Scan List, MHz
(Only applicable in Station or
Station WDS mode.) This will confine scanning only to the
selected channels. The benefits of this are faster scanning
as well as filtering out unwanted AP’s in the results. Site
Survey tool will look for the Access Points in selected
channels only. Once enabled, click Edit to open the
Channel Scan List window.
Select the channels that you want to scan and click OK or
click Close to close the window without any selections.
Output Power
This defines the maximum average
transmit output power (in dBm) of the AirRouter HP. The
output power can be specified using the slider. When
entering the output power value manually, the slider
position will change according to the entered value. The
transmit power level maximum is limited according to the
country regulations. Output power is the output power
delivered to the internal antenna.
Max Data Rate, Mbps
This defines the data rate (in Mbps)
at which the device should transmit wireless packets.
You can fix a specific data rate between MCS 0 and MCS 7.
It is recommended that you use the Automatic option,
especially if you are having trouble getting connected or
losing data at a higher rate. In this case, the lower data
rates will be used automatically. If you select 20 MHz
Channel Spectrum width, the maximum data rate is MCS 7
(65Mbps). If you select 40 MHz Channel Spectrum width
the maximum data rate is MCS7 (150 Mbps).
