Main topic
Description of typical scenes


Sources


Number:
multi-sources is really necessary. In an urban environnement, about 6 antennas can be detected  simultaneously and one of them  induces about 60% of the exposure. In the demo tool, the typical number of antenna should be 4.

Description: far field description with decomposition in  sub-antennas to deal with near field zone


Environment


Dimension:
typically an urban area

Description: different levels of description taking into account the technics of hierarchic navigation from the WP1 and the process of homogenisation of WP2. The most detailed decription of buildings will contain the different materials of the façade and the recesses of balconies and windows.


Interactions


Nature:
reflexions and transmission, no diffraction in the demo tool (diffraction is important from an network's optimization point of view but not from an exposure point of view)

Number: 2/3 reflexions and 1 transmission (only one transmission to penetrate inside the building but once inside the building, no changment of rooms so no more transmission)
