ANALISIS PERFORMANSI SISTEM SELULER CDMA 2000 1X BERDASARKAN KEY PERFORMANCE INDIKATOR (KPI)
ABSTRACT: In this final
measurement and analysis of network performance parameters based KPI (Key
Performance Indicators) such as the Power
Receive of MS (RxLevel), MS Transmit Power (Tx Power), Forward Frame Error Rate (FFER),
Signal Strong (Ec / Io),
Drop Call Rate
and Call Setup
Success Rate. From
the analysis of
test performance based on
KPI parameters can
be seen that
the performance of
the BTS Kota
Baru and BTS Purnama still below ideal standards set
by the company for parameter CSSR (>
97%), respectively 95.63% and 95.95%. As
for the
parameters to meet the
standard KPI (0-2%)
DCR respectively 0.26% and
0.27%. Quality calls for CSSR during test drive is also bad (still below
the standard KPI) by 85%. DCR is still below the standard of 5%. In the area
close to the BTS (<2 km) all successful calls with an average RxLevel still
normal between 69% -95%, Ec / Io normal by 7-8 dB, TxPo normal <23 dBm, and
FFER 0-5% . While the area is far from BTS (> 2 km) most
experienced call drop calls and blocked calls with an average RxLevel no longer
normal between> 95%, Ec / Io no longer normal> 9 dB, TxPo no longer
normal> 23 dBm, and FFER> 5%. This is what causes the fall in performance
CSSR and DCR. The better the RF parameters of the BTS, the less likely it will
drop the call and blocked calls. The smaller the drop the call and blocked call
quality performance CSSR and
DCR will increase (KPI standards). That is, the RF parameters and
performance parameters are closely related. To achieve an ideal performance,
both performance it must meet the standards of corporate ideal. Efforts that
can be done such that the
orientation of the
antenna sector, then
the addition of
a repeater to
increase coverage power
that can be reached, the addition of modules to
increase the capacity of CEMA BTS, or the addition of new base stations when the
area was still solid drop call and blocked calls.
