Channel Width Performance
The Channel Width Performance visualization allows the user to view the degree to which a client is
able to consume the channel width while transmitting and receiving data packets when associated with
an AP. You can use this visualization to verify whether clients associating and transmitting/receiving
data with 802.11 N APs (configurable in 20/40 MHz channel) are able to use the full channel width.
This visualization makes use of available measurement data only when data is being transferred. Thus,
to view this heat map, it is mandatory for you to perform measurement surveys. These surveys should
be performed in the AP Performance mode using the custom driver by enforcing data transfer between
the AP and the client.
The amount of channel width being used can be judged only from the packets being exchanged during
data transfer. You can use the Association status filter to select/deselect the MACs for which the
visualization is to be viewed.
