Propagation into and within Buildings At

Investigations of propagation into, and within, buildings at 900, J800 and 2300 MHz have been undertaken. The composite Rayleigh-plus-log-normal distribution successfully modelled the measured cumulative distributions of all measurements. The average measured penetration loss at ground floor level was found to be 14.2, 13.4 and 12.8 dB respectively at 900, 1800 and 2300 MHz. The rate of change of penetration loss with height was -1.4 dB per floor. The rate of change of mean signal level for signals travelling within buildings was, on average, 8.5 dB per floor. The path loss attenuation factor, n, that best modelled the within-building measurement was found to be 5.3, 5.5 and 6.0 respectively for 900, 1800 and 2300 MHz.
