Analisis Perencanaan Transmisi Microwave Link antara Semarang-Magelang untuk Radio Access Long Term Evolution (LTE)

Abstract

Telecommunication technology that is widely used to communicate in the internet era today is Long Term Evolution (LTE) technology. In carrying out LTE services, the link is needed between the access network and the core or commonly known as backhaul. One of the backhaul widely used to connect a communication link is a microwave backhaul. The application of a microwave link uses extensively for the line of sight (LOS) communication. Therefore, this microwave link planning is not easy because there will be many factors that influenced the communication link, include barriers, fading, attenuation, noise, and distance. In this research, microwave link planning will be carried out between the Semarang City and the Magelang City using three scenarios. The first scenario conducted by using single-hop or direct communication, the second scenario using an active repeater, then the third scenario using the passive repeater. The last result shows that the most suitable scene to be applied in the Semarang-Magelang microwave link is the second scenario. Using active repeater, which reflecting and amplifying the Tx site signal towards the Rx site, is considered to be a solution for the link trajectory, which contained high obstacle and great distance. Using the second scenario from this research, showing that the signal power at Semarang and Magelang site is-54,67 dBm and-48,66 dBm. These signals are above both of Rx threshold site, that is-67,50 dBm.

Long Term Evolution Network Planning Using The Backhaul Microwave Link in The Village Wangunharja Lembang District

“…Then, on research [3], which describes LTE network planning using microwave backhaul in central Sumba District. Then in research [4] explains regarding LTE network planning using microwave backhaul on the island G(Golf) Reclamation. In this research, planning is carried out LTE network with microwave backhaul on Wangunharja Village uses software simulation.…”

“…Collected data is the existing condition of the village Wangunharja and also looking for information about how the condition of the internet network in The village uses the drive test method. The second stage is planning LTE network [5] as in research [2] and [4] based on capacity calculations and coverage. For capacity calculations, population data is required current and perform approximate calculations population in the next five years then do the calculations to find the minimum number of sites required based on total population.…”

“…After searching number of sites on planning and capacity network, then determine the number of sites the most of the two plans that Then proceed with the planning simulation using simulation software. After determine the coordinates of the latest site, next measurements of the microwave backhaul link were carried out as in the study [4] using three scenarios with frequency different. By way of link measurement budget on the microwave backhaul link in order get RSL > -79 dBm and availability > 99.99%.…”
