Optimize Wireless Network Design and Performance
To optimize the performance of a wireless network, the network
designer should seek the best SNR (Signal-to-Noise Ratio)
possible. Signal level can be predicted and planned based on
the transmit power, antenna gain, distance, and frequency band.
However, a common problem with unlicensed wireless bands
(2.4 GHz, 5 GHz, etc.) is that noise cannot be predicted, and clean
spectrum is not guaranteed on any certain frequencies. Previously, an off‑the‑shelf spectrum analyzer (which may cost upwards of
$10,000) was required to conduct a site survey or spectrum analysis at the installation site of the wireless equipment. Now integrated
on all Ubiquiti Networks™ airMAX® M products, airView® provides powerful spectrum analyzer functionality, removing the need to rent
or purchase additional equipment for doing site surveys.
Analyze Frequency Usage and Activity Levels Onsite
airView allows network designers to identify noise signatures and plan their networks to minimize noise interference. airView accurately
depicts the frequencies currently in use by other devices, how active the devices on those frequencies are, and how much noise or
interference may be expected if a wireless network operates on or near certain frequencies. Using airView, network designers can avoid
highly used channels and set up new access points on channels showing the least usage. In airView, there are three spectral views,
each of which represents different data.
Waterfall View
A time-based graph shows the aggregate energy collected since the start of the airView session
for each frequency. The power of the energy (in dBm) is displayed across the frequency span,
and a new row is inserted every few seconds. The color of the energy denotes the amplitude
(or strength) of the signal.
Waveform View
An activity-based graph shows the aggregate energy collected since the start of the airView
session. The power of the energy (in dBm) is shown across the frequency span. The spectral
view over time essentially displays the steady-state RF energy signature of a given environment.
Real-time Chart
A graph displays a traditional spectrum analyzer in which energy (in dBm) is shown in real
time as a function of frequency. There are three traces in this view: Max Hold, which updates
and holds maximum power levels across the frequency since the start of an airView session;
Average, which shows the running energy average across frequency; and Real-time, which
displays the real‑time energy seen by airView as a function of frequency.
