Design And Implementation Of Multisite Cellular Network Based On Open Source System For Remote Areas

Blank spots are still a problem in some areas in Indonesia so that in some areas internet data services are not covered. One solution to overcome this problem is by building a transceiver system using an Open Source Mobile Communication (OSMOCOM). However, this system has relatively low power with a narrow coverage area, so a multisite scheme is needed to cover a wider area. Therefore, in this study, an open source cellular network based on OSMOCOM was developed and implemented that can deliver mobile network with data services and supports multisite schemes. We designed this system as a second and half generation (2.5) of cellular communication technology. From the test results of the realized system, the multisite network can work synchronously where the Mobile Station has received data services at all realized sites. Mobile Station can access the internet with an average throughput of 52.8 Kbps and guaranteed package loss of not more than 10%. Handover mechanism can work properly where it can move the Mobile Station from the original cell to the neighboring cell and vice versa based on the power received criteria. In the future, the proposed system is expected to be applied in remote areas or areas which is not covered by cellular services.
