New: EN 300 328 v1.9.1 and EN 300 893 v1.8.1

The European Telecommunications Standards Institute (ETSI) has updated two GHz band standards. Mandatory for market access in Europe, the updated standards will be enforced in November 2016.

  • ETSI EN 300 328 v1.9.1
  • ETSI EN 300 893 v1.8.1

Laird carries a full line of Bluetooth and Wi-Fi modules that are compliant with the current ETSI standard EN 300 328. Laird seeks CE (Europe) approval for all wireless modules to significantly decrease the burden on OEM developers. In order to ensure clarity for all Laird customers:

  • All Laird modules are fully tested and compliant with the current version 1.8.1 of the standard which expires on November 30, 2016.
  • All Laird radios are in the process of being tested and fully compliant with the newest version 1.9.1.

Updated test reports and Declaration of Conformity will be available upon request.

TÜV SÜD provides a brief overview of the differences between v1.8.1 and v1.9.1 of the standard:

  • If a product is compliant with version 1.8.1 then no re-testing is required. Applicants may update their Technical Construction File (TCF), detailing that the changes in version 1.9.1 do not affect the compliance of their products and therefore conformity against version 1.9.1 can be assumed. The Declaration of Conformity (DoC), can then be updated to V1.9.1. It is advisable to include an updated Application form in the TCF (see Annex E of EN 300 328 V1.9.1).
  • New declaration is required by manufacturers if Geo-Location Capability is supported (No test requirement). If using V1.8.1 test results for V1.9.1, this will need to be factored into the Technical Construction File (TCF), (may be satisfied by completion of EN 300 328 v1.9.1 Application form and inclusion in the TCF).
  • Manufacturers may provide a statistical analysis of the ‘Accumulated Transmit Time and Frequency Occupation’ (Clause 5.3.4), applicable to Frequency Hopping devices such as Bluetooth. This may reduce testing time and cost to the manufacturer. This change also provides clarification and alternative options when the requirements are not fulfilled 100% of the time.
  • In the application form, EN 300 328 V1.9.1 no longer refers to the values of ‘R’ and ‘Q’. Manufacturers no longer need to contact chipset vendors for this information. The minimum Clear Channel Assessment (CCA) value a manufacturer can declare has been reduced from 20 µs to 18 µs.
  •  Testing Transmitter Unwanted Emissions in the out-of-band domain (Clause 5.3.9) at extreme temperatures is no longer a requirement, reducing test time and cost to the applicant.
  • The receiver blocking requirement is reduced from -30 dBm to -35 dBm (Clause 5.3.7).
  • Other changes to the standard include clarifications and additional wording to assist manufacturers and test labs during the test process.
