Powerful Features Free to Use

Wisnetworks spectrum analyzer is a revolutionary product which integrated in all Wisnetworks radios. It's useful in studying all RF energy contributors in the 2.4GHz/5GHz band, but has particularly useful tools that make it ideal for optimizing wireless networks. 

Waterfall Chart

This time-based graph shows the aggregate energy collected since the start of an analyzer session, over time for each frequency. The power of the energy in dBm is shown across the frequency span and one row is inserted in this graph every few seconds.

It is important to note that the color of the energy designates its amplitude. The darker colors (Blues and darker shades) mean very low to low energy levels at that frequency bin, whereas increasingly brighter colors (ie: Green, Yellow, Orange, and finally Red) designate increasingly higher energy levels at the specific frequency bin.

The Waterfall View's legend (top-right corner) provides a numerical guide associating the various colors to power levels (dBm). The low end of that legend (left) is always adjusted with the calculated noise floor, and the high end (right) is set to the highest detected power level since the start of the session.

Channel Usage Chart

This graph is ideal for determining the best channel to setup a WiFi network for optimal performance. In the graph, each WiFi channel is represented by a bar displaying a percentage representing the relative "crowdedness" of that specific channel.This percentage is calculated by analyzing both the popularity and the strength of RF energy in that channel since the start of a analyzer session. An installer could use this view to optimize a network installation by avoiding highly used channels.

Energy Distribution

This graph shows the aggregate energy collected since the start of the analyzer. The power of the energy in dBm is shown across the frequency span. A Blue color will mean energy at a particular strength and frequency appears in the air with a relatively low occurence, whereas increasingly brighter colors (ie: Green, Yellow, Orange, and finally Red) designate energy appearing at a specific power/frequency with higher occurrence. The spectral view over time will essentially display the steady-state RF energy signature of a given environment.

Real-time

This graph displays a traditional Spectrum Analyzer in which energy (in dBm) is shown real-time as a function of frequency. There are three traces in this view: Max Hold, this trace will update and hold maximum power levels across the frequency. Average, this trace shows the running average energy across frequency. Real-time, this trace shows the real-time energy seen by the radio device as a function of frequency.
