The PHY rate used in the AP-client connection is determined by the
capabilities of the AP and the capabilities of the client. For
example, an 802.11ac AP that supports three spatial streams and 80
MHz channels can provide data rates up to 1,300 Mbps. However, if
the client is limited to 802.11n, two spatial streams, and 40 MHz
channels, the PHY rate will not exceed 300 Mbps.
Using the Client Capabilities panel, you can simulate different
types of clients, and this affects the
visualizations. You can selected the
(802.11 a/b/g/n/ac/ax, or 802.11 a/b/g),
(20, 40, 80, or 160 MHz), and
(between 1 and 4). By default, client capabilities are set to the
best real-world values: 802.11 a/b/g/n/ac, 80 MHz channel
width, and three spatial streams. While the 802.11ac standard
allows up to eight spatial streams and up to 160 MHz channel width,
such clients currently do not exist. If you want to visualize
constrained by the client capabilities, you can do so by adjusting
fields can be used to simulate clients that have radios that are
much more or much less sensitive than average. Setting a negative
value simulates a client that has a “weak” radio, i.e. bad
reception. Setting a positive value simulates a client that has a
“strong” radio, i.e. good reception. The correction affects all
visualizations applicable to passive surveys. Normally, you should
not change the default zero values unless you are a very
experienced user and know exactly what you are doing.
field allows you to create several frequently used client
configurations and switch between them effortlessly.
Note that the client capabilities configured in this pane affect
only passive surveys and predictive models; they do not affect
active surveys, because in an active survey, PHY rates depend on
the actual client adapter that you use.
