⌘Propagation scenario (ITU-R)
Radio coverage [km2] | Distance [km] | speed of mobile [km/h] | type of cell | |
Indoor office environment | 0.01 | 0.1 | 3 | picocell in open space environment |
Pedestrian mode | 4 | 2 | 3 | Microcell |
Vehicle | 150 | 13 | 120 | Macrocell |

- impact on walls?
⌘Propagation models
- Environments (indoor, outdoor to indoor, vehicular)
- outside (Lee, Okumura, Hata, Unik/COST231-Hata, Unik/COST231-Walfish-Ikegami)
- inside (One-slope, multiwall, linear attenuation)

we will focus only on ETSI models: statistical models to generate path losses and time delay structures for paths in each test environment.
