Co-existence of Terrestrial TV Broadcasting and International Mobile Telecommunication (IMT): An Interference Case Study using SEAMCAT
Organized by: IRC for Communication Systems and Sensing
In this webinar, the extent of usage of Digital Terrestrial Broadcasting (DTTB) services which mainly uses the 600 MHz band (614 MHz – 698 MHz) of the radio spectrum is reviewed. Regulators are trying to squeeze some part of the spectrum from this band. According to the current trend, the usage of this band may be allocated to launch International Mobile Telecommunication (IMT) system for their services. This session addresses the study of the co-existence of DTTB and IMT systems by performing the interference analysis and determining the coordination distance if the two systems are present in two neighboring countries. In the global arena, several countries have agreed to deploy the IMT services on their side while the DTTB system is still in place in the adjacent country. A case study of Saudi Arabia and one of its neighbors will be presented defining a coordination distance between the two systems which allow them to function amicably as per the set guidelines by the International Telecommunication Union (ITU) and the spectrum management policy of the Communication and Information Technology Commission (CITC). The interference analysis is performed using an open-source SEAMCAT tool which is a simulation tool to study the interference using the Monte-Carlo approach. Demonstration of the SEAMCAT will be given at the later part of the presentation.
