Chapter 2: Ubiquiti Logo Tab
The Ubiquiti logo tab displays settings to enable, launch,
and change settings for Ubiquiti’s proprietary features,
including:
•
airMAX ™ Provides superior wireless performance, more
clients per Access Point (AP), and lower latency under
load.
• airSelect ™ Dynamically changes the wireless channel to
avoid interference.
• airView ™ Ubiquiti’s spectrum analyzer.
• airSync ™ Synchronizes transmissions by GPS Series
devices to eliminate co-location transmit interference.
Note: By default, indoor products, such as the
airRouter, do not display the Ubiquiti logo tab.
However, you can enable the Ubiquiti logo tab
through the System tab > Miscellaneous > airMAX
Technology Features. For more information, see
“Miscellaneous” on page 57.
Change To save or test your changes, click Change.
A new message appears. You have three options:
•
Apply To immediately save your changes, click Apply.
• Test To try the changes without saving them, click
Test. To keep the changes, click Apply. If you do not
click Apply within 180 seconds (the countdown is
displayed), the device times out and resumes its earlier
configuration.
• Discard To cancel your changes, click Discard.
airMAX Settings
airMAX is Ubiquiti’s proprietary Time Division Multiple
Access (TDMA) polling technology. airMAX improves
overall performance in Point-to-Point (PtP) and
Point-to-MultiPoint (PtMP) installations and noisy
environments because it reduces latency, increases
throughput, and offers better tolerance against
interference. Because of its advantages, airMAX also
increases the maximum possible number of users that can
associate with an AP that uses airMAX.
airMAX assigns time slots for each device communication
to avoid the “hidden node” problem, which occurs when
a node is visible from a wireless AP, but not from other
nodes communicating with the originating AP.
airMAX also features advanced Quality of Service (QoS)
autodetection settings. For airMAX to classify and
differentiate types of traffic when applying QoS rules,
the traffic must have a special value within the TOS
(Type of Service) range and set in the IP Header DSCP
(Differentiated Services Code Point) field. The original
software or hardware device is responsible for setting this
value; airMAX will prioritize traffic only if this value is set.
There are four WME (Wireless Multimedia Enhancements)
categories, which range from lowest to highest priority in
this order:
• Best Effort
• Background
• Video
• Voice
