Technical experts of IEC TC106 and ICES TC34 continued their rapid pace on electromagnetic exposure assessment standardization. Following the completion of two significant Specific Absorption Rate (SAR) standards, this meeting focused on preparation for the realization of 5G and IoT (Internet of Things) communication technologies. Robust and high-quality exposure assessment is key to providing public confidence in the safety of these systems.
IEC TC106 and ICES TC34 met jointly to draft electromagnetic exposure assessment standards in Paris from June 4‒7, 2018. The meeting was graciously hosted by French regulatory agency ANFR (Agence Nationale des Frequencies.
Joint Working Groups, established by IEC and IEEE last year, have the mandate to complete two standards for exposure assessment of millimeter wave devices by 2020, when 5G rollout is expected. At millimeter wave frequencies (10‒300 GHz), power density is the basic restriction for human exposure to electromagnetic fields. This is a new frontier in exposure assessment, and many questions are being asked about the best way to assess power density when a person is in the near field of the radiating device. The IT'IS Foundation is among a group of leading researchers working on this issue. The committee drafts of both standards are scheduled to be completed at our next meeting in September in Stockholm.
At the Paris meeting it was decided to use a performance-based approach for the 5G measurement standard. This open approach allows equipment makers to develop innovative measurement techniques. A strong emphasis on validation and verification is applied to ensure high confidence in the results.
This was the inaugural meeting of IEEE Project Team 1528.7 to develop a guide for IoT exposure assessment. The goal is to clarify testing requirements and procedures for a wide range of IoT use cases. Challenges being discussed include how to evaluate exposure from multiple IoT devices and devices operating simultaneously at different frequency bands.
Within the last 12 months, IEC TC106 and ICES TC34 completed several exposure assessment standards:
This pace shows no sign of slowing down. The group celebrated the completion of two draft standards that are being prepared for voting:
