| Summary: | The International Telecommunication Union for Radiocommunication (ITU-R) became involved with the spectrum allocation for next generation mobile communication services in World Radio Communication conference 2007 (WRC- 07). The reason is to minimize the adjacent channel interference between Mobile service and DVB-T system within the same geographical area. Therefore the objective of this research is to study the compatibility between Mobile services as a case study for the International Mobile Telecommunication (IMT-Advanced) and Digital Video Broadcasting - Terrestrial (DVB-T) in the 790 to 862 MHz frequency band. This research also involves the studies and propagation characteristics within this band which can provide better coverage. Possibility of coexistence and sharing analysis were obtained by taking into account the detailed calculations of the path loss effect by using the practical parameters of DVB-T and Mobile service. The interference has been analyzed and simulated for several environments (rural and suburban) in different channel bandwidths for Mobile service at 5MHz and 20MHz, and in different transmitted power for Digital Video Broadcasting - Terrestrial. From simulation on ICS telecom (Information Communication Solutions) software the best separation distance are 21.73 Km and 15.88 Km for bandwidth of 5MHz and 20 MHz respectively. In the simulation two scenarios in two different places; Johor Bahru and Terual state in France were applied. The project involves identification of the spectrum suitability for systems to operate in the band 790 to 862 MHz. This is done by taking into account that the operation of broadcasting stations in the same geographical area may create incompatibility issues and intersystem interference between two wireless communication systems. |
