Analysis on Indonesia Future Railway Mobile Communication System at 900 and 1900 MHz

In this paper, we propose Indonesia railway channel models and analyze the performance of Indonesia future railway mobile communication systems (FRMCS) at 900 and 1900 MHz via the outage probability derived from the models. We use the existing standard of FRMCS, especially the frequency and the bandwidth, for the performance evaluations. To derive the Indonesia channel models, we consider the environmental parameters of Bandung City expecting that Bandung can represent the conditions of almost many cities of Indonesia. To solve the trade-off between frequency and path loss, we perform a series of computer simulations in terms of cumulative distribution function (CDF) of the received power, channel capacity, and outage probability to support the analysis in this paper. We found that the capacity of FRMCS at 1900 MHz is higher compared to that at 900 MHz although the frequency of 1900 MHz may experience higher loss compared to 900 MHz. This result is expected to help the analysis required for the decision on the suitable frequency as well as the expected capacity of the Indonesia FRMCS.
