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

These questions are valid for all of the following impulse responses
establish table (L free space, pedestrial, outdoor, ...) with typical values for 900 and 2000 MHz and distances from 100 to 3000 m
Typical ETSI parameters: 8 kbps, BER < 10'^-3^', 20 ms delay, 50 % activity
