Abstract :
The need for telecommunications technology, especially cellular, is
increasing on each day. Cellular communication is now not only carried out for
activities inside buildings such as work or school, but also in outdoor
environments such as amusement parks, which have many users. Andhang
Pangrenan City Park is located in a suburban area and surrounded by buildings.
With the large number of visitors each day, the level of cellular communication
traffic becomes high, so it requires a network system to maintain the continuity of
communication by all users within the location. In this final project, planning for
microcell network 4G LTE 900 MHz will be carried out with COST 231 WalfischIkegami
propagation model in Andhang Pangrenan Park. Planning is done by
calculating the link budget based on coverage. Simulating this microcell network
is using RPS 5.4 software, and is done with 4 simulation scenarios. The first
scenario with 1 AP is placed on the rooftop of a building in the middle of the park.
The second scenario with 1 AP is placed on the rooftop of one of the tallest
buildings in a row of shops. The third scenario and the fourth scenario use 2 APs
to bring up the SIR parameter values, by placing the randomized AP position.
From the results of the simulations that have been carried out, the RSRP values
for simulation scenarios 1 to 4 are -76.17 dBm, -75.96 dBm, -73.46 dBm, and 72.93
dBm.
While
the
value
of
SIR
for
scenarios
3
and
4
is
6.19
dB
and
6.61
dB.
So
that
the
best
scenario
is
obtained,
that
is
the
fourth
scenario
with
RSRP
value
of
-72.93
dBm,
classified
as
excellent
in
the
KPI
standard.
And
for
the
SIR
value
of
6.61 dB, it
is
classified
as good in
the KPI
standard.
