Introduction
The purpose of this report is to provide calculations of EME levels from the existing facilities at the site and any proposed
additional facilities.
This report provides a summary of levels of radiofrequency (RF) electromagnetic energy (EME) around the wireless base
station at David Cootharaba Davis Road COOTHARABA OLD 4565 . These levels have been calculated by Ericsson using
methodology developed by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).
The maximum EME level calculated for the proposed systems at this site is 0.098% of the public exposure limit.

The ARPANSA Standard
ARPANSA, an Australian Government agency in the Health and Ageing portfolio, has established a Radiation Protection
Standard specifying limits for generai public exposure to RF transmissions at frequencies used by wireless base stations. The
Australian Communications and Media Authority (ACMA) mandates the exposure limits of the ARPANSA Standard.

How the EME is calculated in this report
The procedure used for these calculations is documented in the ARPANSA Technical Report "Radio Frequency EME Exposure
Levels - Prediction Methodologies" which is available at htlp:/lwww.arpansa.gov.au.
RF EME values are calculated at 1.5m above ground at various distances from the base station, assuming level ground.
The estimate is based on worst-case scenario, including:
    • wireless base station transmitlers for mobile and broadband data operating at maximum power
    • simultaneous telephone calls and data transmission
    • an unobstructed line of sight view to the antennas.
In practice, exposures are usually lower because:
     • the presence of buildings, trees and other features of the environment reduces signal strength
     • the base station automatically adjusts transmit power to the minimum required.
Maximum EME levels are estimated in 360. circular bands out to 500m from the base station.
These leveis are cumulative and take into account emissions from all mobile phone antennas at this site.
The EME levels are presented in three different units:
       • volts per metre (Vim) - the electric field component of the RF wave
       • milliwatls per square metre (mW/m') - the power density (or rate of flow of RF energy per unit area)
       • percentage (%) of the ARPANSA Standard public exposure limit (the public exposure limit = 100%).

Results
The maximum EME level calculated for the proposed systems at this site is 1.92 Vim; equivalent to 9.78 mW/m' or 0.098% of
the public exposure limit.
