Estimating number of APs

Hi, 

 

I´m reviewing ACDP Official Certification Study Guide and I have a doubt. In RF Planning module, Aruba indicates a formula to estimate number of APs for two ways: 

 

- Coverage based design (estimate) 

 

Example calculation: 

100,000 sq footage building 

100,000/5000 --- 40 APs

 

- Capacity based design - High Density (estimate)

 

Example calculation: 

100,000 sq footage building 

100,000/2500 --- 66 APs

 

In both cases, when I make the math, the result is different. In first case I get 20 APs, and the second 40 APs. What could be the mistake?

 

Attached the image of the book calculation.

 

Thanks for your help.

Re: Estimating number of APs

It's a typo in the book. The recommendation in the book for coverage is  one AP for every 5000 sq feet, so 100,000/5000 = 20

 

For capacity it is one AP for every 2500 sq feet, so 100,000/2500=40

 

For high-capacity it is one AP for every 1500 sq feet, so 100,000/1500=66

 

I hope this helps,
