20. 20  Comparison with experimental data and theoretical predicting model presented above shows a good agreement between them not only on qualitative,but also on qualitative level.  Both theoretical results and measurements showed us that we get the maximum energy at angle φ~0 and when the angle is increases the strength of the signal is decreases.  Good agreement between theory and experiments allows us to emphasize possibility to use the combined “a long Corridor “ and between rooms “models for prediction of Signal Power Distribution in joint 2D and 3D domains, AOA, TOA and distance, for various indoor environments  This approach will allow to serve each subscriber located inside building in different directions and working via internet in different periods of time.
