coverage area

In the Huawei_Indoor_WLAN_Deployment_Guide it says:

"It is recommended that you take the coverage radius of each AP as 20 m in WLAN planning.

Note: This recommendation applies to ideal scenarios with no interference and obstacles and in which
customers have no specific requirement on field strength."

Thank you for your reply. 

but as  i know AP5010  is coverage area is 100m.  the AP6510DN-AGN  &AP8130DN is higher then AP5010.  I think  this two AP should be distance  more than 100m .

Yes, I think the guide indicates this coverage radius for indoor environments, such as offices for example.

Good luck!
