Remote electromagnetic energy (EME) power logging

Today we take connectivity for granted, particularly in first world countries like ours. When using devices to connect to a vast network for everyday communication, we are generally unaware of the policies and procedures that are required for implementation. Electromagnetic energy (EME) exposure is something that is an underlying necessity for wireless connectivity. This has become increasingly important in the telecommunications industry when assessing exclusion zones for public health as new technologies (3G, 4G, 5G) will make it considerably harder to comply with regulatory standards. Currently, regulatory standards are based on precautionary methodology, which is restrictive as it relies on theory. The precautionary methodology is limiting to resources, productivity and efficiency. This project aims to show that by using readily available devices, a real-world problem can be solved by collecting accurate data from mobile base stations to find out the real exposure values. This will be achieved by accurately measuring the EME levels produced on site over a period of time. This data will enable us to detect the worst case scenario and provide vital information for more effective designs that meet the regulatory requirements. As the standards allow the six-minute sliding average to be taken, this can then be correlated to traffic from the site so that we in the future will be able to map the exclusion zones more accurately. The profile will provide a complete picture of exposure and traffic that defines the category of the site as either high or normal. Currently, exclusion zones don't account for actual beam tilts using a broad range of 0 to 10 degress for implementing boundary zones. Therefore, the current methodology is a one size fits all approach for all sites, as opposed to the tailored approach proposed by this research. By measuring using real-time logging, Optus will be able to see if this is viable and set an example for change in the industry once proven and verified by the National Association of Testing Authorities (NATA).
