Output Power Management is the ability to set the level of output power.
There may be interference or difficulty with channel assignment when there
is a high density of APs within a coverage area. In this case you can lower
the output power of each access point, thus enabling you to place access
points closer together.
You may set a maximum number of wireless stations that may connect to the
ZyXEL Device. This may be necessary if for example, there is interference
or difficulty with channel assignment due to a high density of APs within a
coverage area.
