Maximum Distance Tables
Important Notice
The maximum distances posted in the tables below are actual tested distance thresholds. However,
in any environment there are many variables, such as barrier composition and construction, and
local environmental interference, that may impact radio performance and cause you to experience
distance thresholds far lower than those specified.
Notes: 1. Line-of-Sight Environment: An environment with no interference or obstruction between
the access point and clients.
2. Office Environment: A typical office or home environment with floor to ceiling obstructions
between the access point and clients.
