|
| ICS Broadcasting instrument for WCDMA,
composed with Feedback signal canceller (ICS
module), RE signal amplifier, communication
and control processor and a terminal unit
for NMS. Target for expense curtail and cancellation
of the ground shading zone. |

Special
Features |
|
|
|
|
1) When ICS receives the signals in
forward and reverse through antenna, it minimizes
the impact of the interference
signal by canceling
feedback signal efficiently through the antenna
between donor and service antenna,
and transmits the satisfying quality
signals through donor and service antenna.
2) It takes accurate measurement and indication the isolation between donor and service antenna.
3) It separates feedback signals between donor and service antenna from regular input signals, measure and indicates.
4) It examines the volume of measured
isolation and canceled feedback signals and produce
maximum output set
automatically within the
standard range with no thermal impacted signal quality.
5) It copes positively with the input
and changes of feedback signals in proportion to
surrounding environmental changes,
and guarantees the most
suitable signal quality and output.
6) It provides audio/video and data
service sent from base station available through
Node-B and linkage,
the Broadcasting instrument
supplies the functions (re; hand off) equivalent
to WCDMA Node-B.
