Determining and Measuring the ESA
As shown in Figure 2-2 , shade the desired ESA on the floor plan. Note areas that
you do not want to include (storage, restroom. etc.) in the coverage. Now, measure
the length and width of the planned ESA, again shown in
Figure 2-2 .

Estimating the Number and Placement of Access Points
To get an idea of how many BayStack 660 Access Points are needed to cover the
ESA, divide the length and width measurements of the desired ESA by 300 feet
(91 meters). Use the higher range to obtain a conservative estimate, since the
range of the BayStack 660 Access Point can be up to 300 feet (91 meters).
Using the measurements from the example in Figure 2-2 , 869 feet
×
509 feet
(265 meters
×
155 meters), the results are 2.9 for the horizontal measurement
and 1.7 for the vertical measurement. Rounding up to the nearest integer, the
estimated number of BayStack 660 Access Points required to cover the chosen
ESA are three across
×
two deep (for a total of six access points).
