Frequency Scan

Introduction

Use the frequency scanner to display conflicting wireless traffic. The center band is the current channel. Other nearby channels are visible.

[$] Ideal channels will display a shorter bar graph. Shorter bar graphs indicate less potential interference.

[i] For more information on wireless, visit the Wireless Overview.


How it works

The frequency scan will continue to sweep through frequencies. Each time it passes a frequency, it takes multiple samples to determine how busy the channel is. Once it finishes scanning all frequencies on the screen, it will repeat.

We encourage you to watch the Frequency Scan through all channels several times. Not all interference is constant, and the wheels samples can miss a brief transmission. Multiple sweeps can help ensure you notice any potential interference.

Example

A: Current Channel

The center frequency in dark blue shows the current selected channel.

B: The Best Channel

The channel with the shortest height, is the best channel. In this case, 914 would be the best. It shows the lowest activity. There will not always be a clear winner. If there is no clear lowest bar, choose one that is in the surrounded by similarly low channels.

C: Indication of Temporary Spikes on a Channel

The white line that sometimes floats above a channel indicates that during a scan a short burst was detected that is higher than the channel's average traffic. This should also be avoided as short bursts can cause brief signal loss.

D: A Busy (Bad) Channel

This channel has a lot of traffic. Should be avoided.

E: Lowest Sample Indication

The black line indicates the lowest sample taken. This information is useful to see volatility on a channel. Large deviations away from the average indicate traffic is present.
