• derived from COST 231
• r is transmitter-receiver distance in m; n is number of floors in the path
• path loss L should always be more than free space loss. Log-normal shadow fading standard deviation of 12 dB
• Path loss model: [dB]

⌘Modelling approach - indoor

Typical ETSI parameters: 8 kbps, BER < 10'^-3^', 20 ms delay, 50 % activity
