This ITU-R Handbook gives the technical basis for predicting the radio propagation in point-to-point, point-to-area, and point-to-multipoint mobile networks.



Propagation within and into buildings and underground

The indoor wireless propagation problem is broadly distinguished from the outdoor wireless propagation problem by much shorter path lengths and the ubiquity and importance of multipath in almost all cases of interest. The mixed problems, outdoor-indoor and indoor-outdoor wireless propagation, which combine aspects of each, will be deferred to the last part of this section. For the indoor-indoor wireless propagation problem, two solution approaches are available, depending on the level of detailed knowledge of the propagation situation. As in the outdoor propagation problem, these subdivide neatly into site-specific and site-general approaches. In what follows, both are discussed.
