Isolation of antenna is one of the most
considerable things in the way of wireless
rely. Moreover, lack of antenna isolation
causes oscillation of wireless repeater system,
so it has limited to operate equipments.
ICS (Interference cancellation System) can
use in the field easily with adapting in real-time
to changeable wireless environment and lacking
of antenna isolation
|
|
 |
Users can complete to set up of ICS application
with just simple fixing, checking antenna
isolation in GUI (Graphic User Interface)
and setting up proper gain considering input
and path-loss.
And also, it makes easy to operate and install
with measuring RSCP, which is the strength
of Node-B signal inputted to donor antenna,
because an incoming signal is free space.
It is possible to do remote and supervisory
control RSC with CDMA data modem and EMS (Equipment
Management System) linked to CDMA network.
