DVB-T2 digital TV transmitter infrastucture optimization (a case study in the jabodetabek area)

Abstract

The design of digital TV DVB-T2 transmitter infrastructure is done by multiplexing broadcasters in Indonesia, at this time there are many who use the concept of analog TV transmitter infrastructure planning, which in its design avoid two transmitters with the same frequency in the service area as it will cause interference to received signal by the public. With Digital TV DVB-T2 technology allows to design 2 transmitter in the area of service without occurring interference to each other (SFN), it is due to the feature of the guard interval that tolerate varying propagation delay between 2 transmitter antenna when the signal received by public. In this paper carried out the design of a digital transmitter infrastructure that utilizes new features DVB-T2 technology to provide Jabodebatek area TV digital broadcasting. To utilize the DVB-T2 features, three design options was proposed Option I use one transmitter, option II use two transmitters and option III use the four transmitters. All option was designed in order to meet the minimum operational parameters that have been set by the government. After designing all options is done, then compared the results technically and economically. Technical analysis is done by comparing the capacity and coverage of the population of each design, economic analysis is done by comparing the analysis of business each design using a calculation of payback period, NPV (Net Present Value) and IRR (Internal Rate of Return). It was concluded from the results that the design that use 4 transmitters is the most optimal to be implemented in the Jabodebatek area. The optimum design obtained 27.87 Mbps in capacity, 99.9% in population coverage (29,408,063 inhabitants) and IRR 9.64%.
