Base station survey - Lower Sandy Bay TAS

Maximum level of RF EME from this base station

The maximum level of RF EME from this base station (full power) determined from measurements at locations around this site was 0.277% of the ARPANSA Standard limit for public exposure.

Highest level of RF EME actually measured

The highest level of RF EME from all nearby base stations actually measured at a location near this site was 0.029% of the ARPANSA Standard limit for public exposure.

The Environmental EME Report for this site (dated 14/08/2007) lists the maximum EME level as 0.24% of the ARPANSA Standard limit for public exposure.

Base station address: Sandown Park, Long Point Road, Lower Sandy Bay TAS

Footnote:

For this base station the measurement of demodulated pilot signals of the spread-spectrum technologies (CDMA, UMTS or WCDMA) was not performed. Extrapolation was done assuming that only the pilot signal was present when in fact a mixture of pilot and traffic signals contributed to the measured value. This assumption leads to over-estimates of the actual RF EME levels, typically by a factor of 2 to 5.
