10.6. Hidden Node Compensation
Depended on the placement of multiple wireless LANs, there is a case that the
wireless LAN communication disturbance caused by other wireless LANs takes
place and the data rate may be fallen off. If the Hidden Node Compensation is
set to Enable, the Wavit11 seizes the wireless LAN communication line prior to
the actual data transmission, so it can mitigate the mutual disturbance of
wireless LAN communication and the degradation of data rate.
What is Hidden Node?
In the wireless LAN system, many wireless LAN
s
communicate each other on the same frequency.
Normally every
wireless LAN senses whether
or not another wireless LAN has
already started the wireless LAN communication so as
not to
disturb the already started wireless LAN communication.
However, some wireless LANs disturb
the already started
wireless LAN communication transmitting the data without
sensing the existence of another wireless LAN communication.
Such a kind of wi
reless LAN that may disturb the other wireless
LAN communication is called Hidden Node.
