There has been a comment in the OJ regarding requirement for spectrum sharing since December 2009:
This version of the standard gives presumption of conformity with the requirements of Article 3(2) of Directive 1999/5/EC under the following condition: The equipment shall implement an adequate spectrum sharing mechanism, e.g. LBT (Listen Before Talk), DAA (Detect And Avoid), etc., in order to comply with the requirement specified in clause 4.3.5 of this version. Such a mechanism shall facilitate sharing between the various technologies and applications which currently exist and in case of congestion, users will be ensured equal access (and as a consequence a graceful degradation of service to all users). Harmonised ways for assessing the efficiency of various sharing mechanisms are currently been developed by ETSI in draft EN 300328 version 1.8.1. V1.8.1 has brought in some additional requirements, but the draft standard has been around for years and the published standard added to the OJ with a 26 month transition period.

It is indeed very unusual for a provision to come into effect without a transition period, and is normally not allowed. If it is allowed, there must be a safety or other over-riding issue to justify it and it must be explained publicly (at least according to many Directives). Were manufacturer experts on the relevant ETSI standards committee unaware of this unusual development? -- OOO - Own Opinions Only.
