36 Installing the Wireless AP
Custom Coverage
Where there are highly reflective objects in proximity to the AP, you can turn off
specific radios to avoid interference and feedback.

Capacity and Cell Sizes
Cell sizes should be estimated based on the number of users, the applications
being used (for example, data/video/voice), and the number of APs available at
the location. The capacity of a cell is defined as the minimum data rate desired for
each sector multiplied by the total number of sectors being used.
Figure 13. Connection Rate vs. Distance
Figure 13 shows relative connection rates for 802.11n vs. 802.11a/g and 802.11b,
and the effect of distance on the connection rates. 802.11ac rates behave like
802.11n over distance—see Figure 23 for 802.11ac data rates). Wireless
environments can vary greatly so the actual rates may be different depending on
the specific network deployment.
