Maximum Distance
Maximum distances posted below are the actual tested distance thresholds. However, there are
many variables such as barrier composition and construction and local environmental interfer-
ence that may impact your actual distances and cause you to experience distance thresholds far
lower than those we post below:
An Outdoor Environment is a line-of-sight environment with no interference or obstruction
between the access point and clients.
An Indoor Environment is a typical office or home environment with floor to ceiling obstruc-
tions between the access point and clients.
