First, a one-slope path-loss model was constructed for each frequency. Path loss exponents below 1.5 at lower frequencies (similar to 1 GHz) indicate a waveguide effect, while the influence of the seats on the propagation at higher frequencies (similar to 2 GHz) results in exponents larger than 2. Finally, a single, frequency-dependent path-loss model was fitted to the total data pool, resulting in a model with a coefficient of determination, R-2, of 0.77.
