Abstract :
High-speed service is currently the main need for transportation that
requires a microwave radio communication system that has been widely used by
one of them on the Indonesian railways communication system that requires
network quality Communication that has a fast response. Transmission of
information using a point to point system is a microwave radio communication
system. Almost every DAOP has gained direct communication access even though
it is separated by far enough distance by using radio waves. The traindispatching
system is voice communication and signaling (information) between the
Traindispatch Centre and Waystation (WS) and the locomotive to control railway
traffic. To support traindispatching system used network backhaul point to point 8
GHz so that all information (voice and data) can be delivered optimally. After
simulation done using Pathloss Software 5.0 using antenna device model HPX6-
77, Microwave model PASOLINK + 8G 33MB, with gain of 40.70 dB, transmission
lines model EWP 77 with loss 5.76 dB/100 m. where at the initial planning Obtained
the average value of the system reliability (availability) 97.266% of the availability
value is not optimal. In this study also discussed about the design of the Backhaul
network optimization, by replacing the antenna device model VP6-77, Microwave
model NEO COMPACT 7-8G 10E1, with a gain of 41.70 dB and using the same
model transmission lines as And after simulating the availability of values
increased to 99.999%.
