The wavemon interface is separated into several different sections, hereby referred to as "screens". Every screen displays information about distinct parameter types and/or in a special manner. For example, the "info" screen shows the current signal and noise levels as bargraphs, while the level histogram shows the exact same values as a level plot, so their development over time can be seen. On startup, you'll see one of the different monitor screens (which of the screens will actually be displayed depends on your configuration). On the bottom, you'll see a bar showing the available screens along with function key strokes.
These screens are currently implemented:
At the Interface section, the name, ESSID and nickname of the current wireless interface are shown.
Below, at the Levels section, you can see four bargraphs showing the quality of the link to the next station (if established), the level of the received signal, the current receiver's noise level and the signal-to-noise ration, which gives a good approximation of the overall signal quality. The colour of the signal level bargraph changes from red to yellow and green at fixed levels, while the colour of the noise level graph is adapted to the current signal level (it turns red when the signal-to-noise-ratio gets below 0dB). If the thresholds are associated with any actions, two arrows on the signal level graph will show the positions of the current thresholds. More on this topic later.
The Statistics section displays packet and byte counters. The first four values, preceded RX and TX, show the current total number of packets received and transceived since the initialization of the interface. The following three values display the number of packets that were discarded from the interface because of invalid network ids, wrong encryption keys and other errors.
Below, at the Info subsection, various wireless-specific parameters of the interface are displayed. What parameters are actually shown may vary and depends on the capabilities and the operation mode of your network device. The top line shows the current frequency the interface operates on, the sensitivity threshold of the receiver and the transmission power. Below, the operation mode of the interface (managed, ad-hoc...) and, if appropriate, the MAC address of the current access point are displayed. The third line shows the current data transfer speed in Mbit/s and the retransmission and fragmentation thresholds. Whether or not the details about encryption show up in the next line depends on the permissions of the user. Finally, the last line displays the power management parameters, if this feature is available and active.
The last section, titled Network, shows - you guessed it - network parameters, such as the interface name and hardware address as well as the interface, netmask and broadcast IP addresses. These parameters are not wireless-related.
