AirMagnet Spectrum XT User Guide
If you place the cursor over a particular channel, a tip screen will appear providing some brief
statistics of the amount data transmitted at the various transmission rates used on that channel.
Channels by Media
The Channels by Media graph shows that volume of WiFi transmissions in kilobytes recorded
on each channel in the selected radio band. It also provides a rough breakdown by 802.11
media type of the transmission on each channel. The X-axis shows all available channels in the
selected band and the types of media used for the transmission; the Y-axis shows the volume
of transmission in kilobytes. See Figure 7-7.
Figure 7-7: Channels by Media graph
Each bar in the Channels by Media graph represents the total amount of data in kilobytes that
has been transmitted on a channel. The WiFi traffic is categorized by the type of 802.11 media
being used. The media are color-coded, with each color representing a specific type of 802.11
media. Table 7-5.
