The Radio Equipment Directive (RED) is a set of standardized rules developed by the European Commission that defines the conditions for putting radio-electric products in the industry. The European Commission issued an Incorporating Action (EU 2020/167) on the harmonized guidelines for communication equipment, which recognized ETSI EN 300 328 as a component of the EU Authoritative Publication and stated that the existing edition (v2.1.1) would be phased out on the 6th of August, 2021.
The ETSI EN 300 328 specification is a harmonized reference for the Radio Devices Regulation (RED) for broad data transfer devices like Wi-Fi devices. The main modifications will affect receiver filtering restrictions, transmitter erroneous emissions restrictions around 470MHz and 1GHz, as well as gear categorization “types” modification.
What are the differences?
1.Terminology and requirements must be clarified.
2.Modification of the standards for Transmitter Unnecessary Emissions.
3.Modifications to test methodologies.
4.Switch to the Transmitter Blocking testing method – this will necessitate a retake.
5.Modifications to reporting standards.
What are you expected to do?
1.Examine your Statement of Conformity to determine which edition of EN 300 328 is now listed.
2.Evaluate whether you have to improve your conformity
3.Carry out any necessary testing to ensure compliance with EN 300 328 V2.2.2.
4.Document this proof in your technological document.
5.Add EN 300 328 V2.2.2 to the Statement of Compliance.
For your information – If you integrate a third-party component and then utilize the third-party Certificate of Conformity in your professional document, you must request the most recent information from your supplier.
New transmitter requirements
The criteria for FHSS technology functioning of both reactive and non-adaptive methods have been clarified; while in a non-adaptive state, the gear should conform to the non-adaptive FHSS technology standards.
Keep in mind: Non-adaptive option is hardly utilized in current Bluetooth products since it is only utilized to link with outdated Bluetooth gadgets that are no more in use.
The Accumulated Transmission Duration, Frequency Usage, as well as Hopping Sequencing standards for FHSS hardware should all be met. The client may offer analytical evidence that the hardware fulfills the Accumulated Transmit Time standards. If the user has filed the testing result, it is now required to provide this data study. TÜV SÜD usually conducts this study and assumes that the user would not supply it.
Clause 4.3.1.4’s test technique has changed; formerly, an RMS detector might have been utilized; now, V2.2.2 specifies that a High point sensor must be utilized. The range of stations identified is almost expected to remain unchanged if the detector technology is changed. As a result, a device that is compatible with V2.1.1 can also be regarded functional with V2.2.2.
The requirements for Transmitter undesired emissions in the specious region have been relaxed. Formerly, the hardware had to reach -54 dBm between 470 and 862 MHz. From 470 MHz to 694 MHz, these wavelength bands have been changed to -54 dBm and -36 dBm, respectively, through 694 MHz to 1 GHz. A gadget that meets the more rigorous requirements of V2.1.1 also meets the requirements of V2.2.2.
New receiver requirements
The receiver blockage minimum efficiency standards have been revised to allow for a Frame Error Rate (FER) of about 10%. Beginning in V2.1.1, the user can no more specify an additional performance requirement. For the authorized usage of hardware, systems that do not allow a Packet Error Rate should have no interruption of communication. Following compensating for in-band aerial component gain in conducted tests or energy flux density (PFD) in projected tests, all Reception Classes indicated in clause 4.3.1.12.4 must now include an obstructing transmission intensity of -34 dBm at the reception of the device [4.3.1.12.4].
In particular, all Reception Classes include a requested signal average output from the accompanying gadget, which is calculated using the device’s filled bandwidth (OCBW). If in transmitted testing where the desired output from the accompanying gadget cannot be detected, the WSMPCD no longer includes computations depending on the intensity of the desired output at the gear’s input. Finally, all Receiver Classes should be evaluated against new inhibiting indications specified in V2.2.2, which were not necessary for V2.1.1.
