CINDOOR: an engineering tool for planning and design of wireless systems in enclosed spaces

This paper presents the program CINDOOR. This program is an engineering tool for aiding in the design, planning, and effective implementation of wireless systems in general enclosed spaces. The method underlying CINDOOR is a flexible approach to the propagation process, allowing analysis of indoor and outdoor environments and the interaction between them. The method is based on a full three-dimensional implementation of GO/UTD. Ray tracing is efficiently carried out by combining image theory with binary space partitioning algorithms. The space-time distribution of the electromagnetic field is processed to obtain a set of magnitudes that form a basis for planning a wireless system: coverage (mean power), fading statistics, power delay profile and associated parameters, such as the rms delay spread and the coherent bandwidth.
