Figure 4.75 - 5 GHz and 2.4 GHz 802.11 packets
The y-axis labels show the channels for each technology and are color-coded: Blue = Classic Bluetooth, Green
= Bluetooth low energy, Orange = 802.11.
The 5 GHz timeline has only 802.11 channel labels, and the rows alternate orange and white, one row per
channel.
The 2.4 GHz timeline has labels for all three technologies. The rows alternate blue and white, one row per
Classic Bluetooth channel. The labels going left-to-right are 802.11 channels, Bluetooth low energy advertising
channels, Bluetooth low energy regular channels, and Classic Bluetooth channels.
The Viewport Packet Range above the timelines shows the packet range and packet count of packets that
would be visible if both timelines were shown (i.e. hiding one of the timelines doesn’t change the packet
range or count). This packet range matches the packet range shown above the viewport in the Throughput
Graph, as it must since the viewport defines the time range used by the timelines. When no packets are in the
time range, each of the two packet numbers is drawn with an arrow to indicate the next packet in each
direction and can be clicked on to navigate to that packet (the packet number changes color when the mouse
pointer is placed on it in this case).
An arrow points to the next packet when no packets are in the time range.
An arrowed packet number changes color when the mouse pointer is on it. Clicking navigates to
that packet.
The header shows information for packets that are selected.
The footer shows the beginning/ending timestamps and visible duration of the timelines.
The ‘i’ buttons bring up channel information windows, which describe channel details for each technology.
They make for interesting reading.
