| Summary: | This report presents the coverage and capacity modelling analysis for Public Safety LTE (Long Term Evolution) in Singapore with the proposed in-building communication system design. A modelling methodology was used to sketch up the building model. Thereafter, simulation results were generated to provide recommendations on the area of coverage and the number of users the proposed in-building communication system can support.
The report would be covering on the literature review of LTE and electromagnetic-wave propagation such as reflection, refraction, diffraction and fading which are aspects of advanced propagation model of fast ray tracing that considers how different surfaces affect indoor propagation. Additionally, considerations used for coverage and capacity planning would be adopted to design the in-building communication system.
The modelling methodology starts with conducting a site survey to obtain information of present radio signal received power within the building of interest. These results would be used for calibration of the 3D model that would be sketched up. An in-building communication system would be designed, and simulation results would be generated with the 3D model and the incorporated fast ray tracing propagation model to achieve a predicted area of coverage and capacity level; to determine if the results meet the requirements needed to be achieved as stated by the users. The results obtained would serve as a recommendation on the area of coverage and the number of users the proposed in-building communication system can support. Additionally, system optimization was done to improve resource utilization and to reduce project capital.
The modelling methodology adopted in this report could be used by RF engineers for future in-building communication system design and implementation |
