Installing the Wi-Fi Array

Custom Coverage

Where there are highly reflective objects in proximity to the Array, you can turn 
off specific radios to avoid interference and feedback.

Figure 14. Custom Coverage

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 Arrays 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 15. Connection Rate vs. Distance 

Figure 15

 shows relative connection rates for 802.11n vs. 802.11a/g and 802.11b, 

and the effect of distance on the connection rates. Wireless environments can vary 
greatly so the actual rates may be different depending on the specific network 
deployment.
