⌘ETSI Indoor Office test environment
- 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
(Source:Radio Wave Propagation for Telecommunication, Springer, and ETSI TR 101 112 V3.2.0 (1998-04))
