Compliance report

EMF compliance report for smartco relay and access point designs 

Summary

SmartCo plan to install a number of Relays and Access Points in a variety of locations. This report provides a generic guideline to ensure that the current limit for EMF in the vicinity of transmitter antennas is not exceeded. The report ensures that the guidelines cover the worst case conditions and in many cases will have a significant safety factor.
The analysis cannot take into account the effect off any nearby transmitters which may add to the cumulative EMF.
The report recommends that the general public are prevented from having access to any area within 1 metre of the antennas.

Background

SmartCo plan to install a number of Relays and Access Point stations as part of their implementation of smart power meters. These stations collect data from surrounding meters and transmit them back to a network node. Two different generic transmitter configurations are planned depending on the role of the specific station
This paper provides an evaluation of the ElectroMagnetic Field strength (EMF), measured as a power flux density, due to these radio transmitters. The analysis uses the current New Zealand Standard NZS2772 to derive a zone around the antennas where the general public should not have access.
