Abstract :
According to the Indonesian Central Bureau of Statistics, Indonesia's population
has reached 264 million. As the population grows, the telecommunications network users
also increase in Indonesia. Along with the increasing number of users, the
telecommunications network services also need to be improved. Indonesia itself has
implemented several telecommunications technologies and one of them is cellular
technology. In cellular technology the media used is air in the form of microwaves which
are commonly called microwaves. Microwave radio communication technology is used as
a means of transmission between the Base Transceiver Station. Because the signal is
transmitted through an air medium, this communication is susceptible to interference
caused by weather changes. In this situation, it can be overcome by the use of passive
repeaters. In this final project microwave network design uses repeaters to back to back
and double flat reflectors with the same hoplink. The design of this microwave network was
carried out in South Sulawesi with the xBantaeng site located at the southern latitude
coordinates 05° 29° 07.04° S and east longitude coordinates 119° 51° 51.49° E. While the
xSinjai site is located at coordinates south latitude 5° 13° 19.23° S and east longitude
coordinates 120° 4° 32.27° E, and southern latitude coordinates 5° 21° 21.08° S and east
longitude coordinates 119° 56° 13.83° E for repeater placement and reflector. This design
uses Pathloss 5.0. For the case in this Final Project both the use of repeater back to back
and double flat reflector both get optimal values. 99,95866% for repeater back to back
capabilities and 99,82100% for double flat reflectors. With the conclusion that the use of
double flat reflector produces better availability.
