Keynote #2: Indonesia broadband frequency roadmap

Abstract

Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. The telecommunication market Indonesia is very pervasive. With more than 350 million subscribers, the total market is more than 100 percent of the population. Technically, this huge market needs the availability of the frequency spectrum used for mobile application. Mobile radio communications have evolved from analog systems in the late 80s, carrying only voice, to more robust GSM/GPRS voice systems, enabling the boom in text messaging to the latest advances in mobile broadband brought by UMTS, HSDPA, and LTE. All radio communications make use of a highly regulated resource: a limited portion of the electromagnetic spectrum. Specific portions of that spectrum are allocated for use by particular technologies. Now, the technology is moving to 5G which will enable much higher speed and much smaller delay, therefore the availability of the spectrum is very much important. Thus, the broadband frequency roadmap should be defined. In this keynote speech, the broadband traffic estimation is explained, followed by the calculation of the bandwidth needed and from which frequency it will be obtained.
