 * 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.
