Software algorithm that improves the efficiency of testing electromagnetic exposure levels of wireless devices.
Wireless devices that come in close contact with people must be tested to ensure that human exposure to electromagnetic radiation is at or under certain standardized levels. 5G technology will drive the next generation of wireless devices and will require more antennas than ever. Each additional antenna requires a substantial increased in the number of electromagnetic exposure measurements, which slows down the safety testing process.
University of Notre Dame researchers have created a software algorithm that enables electromagnetic exposure levels to be accurately determined with fewer measurements, thus reducing the time it takes to test a multi-antenna wireless device for electromagnetic exposure compliance. This technology chooses antenna excitations adaptively in response to previous measurements, thereby significantly reducing the total number of excitations significantly compared to existing methods.
- Optimizes efficiency by reducing the total number of electromagnetic excitations needed to determine compliance
- Improves turnaround time for device prototype testing
- Ready to implement for use with 5G technology
