Your EME hub: industry overview


What is EME?

Radiofrequency (RF) electromagnetic energy (EME)—also known as electromagnetic radiation (EMR)—is the transfer of energy by radio waves. RF EME lies in the frequency range between 3 kilohertz (kHz) and 300 gigahertz (GHz). RF EME is used mainly for communication purposes including mobile phones and base stations, television and radio broadcast towers, radar facilities, some types of remote control devices, and electrical and electronic products.

EME is non-ionising radiation, meaning that it has insufficient energy to remove electrons (ionisation) from atoms and molecules. Unlike ionising radiation, EME exposure does not lead to molecular changes that can damage biological tissue.

Exposure to sufficiently high levels of EME can heat biological tissue. For this reason, governments around the world set EME exposure limits for radiocommunications products.

Who regulates EME?

In Australia, EME is regulated through a combination of:

The Commonwealth Department of Communications and the Arts has produced a video explaining EME regulation in Australia with particular focus to base stations.

What are the ACMA’s responsibilities?

The ACMA regulates EME mobile and portable products and installations (for example, mobile phones, smart meters and mobile phone base stations).

The ACMA regulates EME through:

The ACMA’s EME compliance activities include targeted and random audits of licensees and suppliers of radiocommunications transmitters. A key component of the EME compliance activities is the visual inspection of transmitter sites, which the ACMA undertakes as part of routine field work. The ACMA has focused its compliance activities on emerging technologies including smart meters.

If you have questions or feedback about complying with EME obligations, please contact the ACMA’s Customer Service Centre on 1300 850 115 or
