Summary of ETSI EN Wireless RF Compliance Testing Information
This wireless telecom ETSI EN 303 417 document specifies characteristics and methods of measurement for wireless power transmission systems. These systems use technologies other than radio frequency beam, in the 19 – 21 kHz, 59 – 61 kHz. 79 – 90 kHz, 100 – 300 kHz, and 6,765 – 6,795 kHz ranges.
This intentional radiator RF testing document also covers wireless power transmission systems. These are regarded as radio equipment since they include inherent radio communication functionality or radiodetermination via the WPT interface.
Such systems consist of:
- A power transmitter, with additional communication capability to control the charge function, in conjunction with the receiving part. The power transmitter could also be named as a base station.
- A power receiver, which supplies the received energy to a mobile device. It must also perform a control/supervision function for the mobile device status and charge operation. Both parts can transmit and receive data in addition to the power transmission mode.
Lastly, it is important to note that this document covers fixed, mobile, and portable devices.
Scope of ETSI EN Intentional Radiator Testing
In this clause, all general considerations for the testing of wireless power transmission systems using technologies other than specified radio beams are given. This test covers all different operational modes.
A Wireless Power Transmission (WPT) system consists of a base station and a mobile device. These devices must be within proximity of each other. The performance of a WPT system is dependent on the relegated operational mode.
For the receiver performance tests, the WPT system produces an appropriate output under normal conditions as mentioned below:
- Use as intended without degradation of performance
- Degradation of the performance is indicated by the WPT system as described in the manual.
Because of the close interaction between a base station and a mobile device, the manufacturer provides all parts for the presentation of the equipment being tested. The mechanical orientation of both parts is provided. This is because it will affect the radiated emissions. For using different batteries or power of receiving parts with one base station, the worst-case combinations concerning radiated emissions must be stated before testing.
In certain cases, it is not possible to provide samples of all possible mobile devices due to unavailability. It must be noted that the base station was developed based on certain mobile devices. These base station/mobile device combinations must be provided during testing.
Additional appropriate test conditions include:
- The mechanical setup/alignment
- The maximum allowed values for the offset within the alignment
- The mechanical orientation
- The permitted range of frequencies
- The range of operating conditions including the duty cycle or pulsing operational parameter
- Power requirements
- Information about which part of the WPT system can be interpreted as a transmitter
