Client Capabilities

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 Expected PHY Rate and Requirements visualizations. You can selected the Supported standards (802.11 a/b/g/n/ac/ax, or 802.11 a/b/g), Channel width (20, 40, 80, or 160 MHz), and Spatial streams (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 the Expected PHY Rate constrained by the client capabilities, you can do so by adjusting them.

The Signal correction 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.

The Preset 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.
