What is PD IEC TR 63170- Measurement procedure- Power density about?
PD IEC TR 63170 is a safety standard on measurement procedure for the evaluation of power density related to human exposure to radio frequency fields from wireless communication devices.
PD IEC TR 63170 describes the state of the art measurement techniques and test approaches for evaluating the local and spatial-average incident power density of wireless devices operating near the users between 6 GHz and 100 GHz.
PD IEC TR 63170 guidance for testing portable devices in the applicable operating position(s) near the human body, such as mobile phones, tablets, wearable devices, etc. The methods described in PD IEC TR 63170 may also apply to exposures in proximity to base stations. PD IEC TR 63170 also gives guidance on how to assess exposure from multiple simultaneous transmitters operating below and above 6 GHz (including combined exposure of SAR and power density).
Note 1: Power density measurements above 6 GHz are also applicable near the equipment, but no detailed protocol is available at this stage.
Note 2: Compliance of devices with sufficiently low radiated power that is incapable of exceeding basic restrictions is addressed by IEC 62479 [2] and therefore not described in PD IEC TR 63170.
Who is PD IEC TR 63170- Measurement procedure- Power density for?
PD IEC TR 63170 on measurement procedure for the evaluation of power density related to human exposure to radio frequency fields from wireless communication devices is relevant to:
- Electrical engineers
- Electromagnetic engineers and designers
- Electricians
- Testing authorities
- Manufacturers of wireless devices
Why should you use PD IEC TR 63170- Measurement procedure- Power density?
With the rapid development of new wireless technologies in the frequency range 6 GHz to 100 GHz for the fifth-generation mobile technology (5G), there is a need to establish assessment procedures to ensure compliance of wireless devices with electromagnetic exposure limits.
PD IEC TR 63170 describes methods and measurement techniques for the evaluation of power density related to human exposures due to electromagnetic field (EMF) transmitting devices operating near the user at frequencies between 6 GHz and 100 GHz where basic restrictions can be expressed in terms of power density. The types of devices include but are not limited to mobile telephones, tablets, and laptops. PD IEC TR 63170 serves as the starting point for an International Standard. The methodologies and approaches described in PD IEC TR 63170 can be useful for the assessment of early 5G products introduced for consumer trials. PD IEC TR 63170 also contains recommendations for future standardization work and highlights areas that may require additional investigation or consideration. A few examples for measurements of a mock-up device characterized by an antenna array operating at about 28 GHz are given in Annex H. SAR tests are applicable when the compliance distance is near the radiating sources in the frequency range 300 MHz to 6 GHz. The measurements are carried out with good laboratory practice, and other local and national compliance requirements.
Overall, PD IEC TR 63170 is useful as it helps in evaluating the power density, in the context of human exposures to the radio frequency fields from wireless communication devices operating between 6 GHz and 100 GHz are well established.
