DESCRIPTION
RTS/CTS Threshold
In a wireless network which covers a large area, wireless devices 
are sometimes not aware of each other’s presence.  This may cause 
them to send information to the AP at the same time and result in 
information colliding and not getting through.
By setting this value lower than the default value, the wireless 
devices must sometimes get permission to send information to the 
ZyXEL Device. The lower the value, the more often the devices must 
get permission.
If this value is greater than the fragmentation threshold value (see 
below), then wireless devices never have to get permission to send 
information to the ZyXEL Device.
Authentication
The process of verifying whether a wireless device is allowed to use 
the wireless network.
Fragmentation 
Threshold
A small fragmentation threshold is recommended for busy networks, 
while a larger threshold provides faster performance if the network 
is not very busy.
