EU EN 301 893 RLAN 5 GHz - Adaptivity

[occounty]

Hi all,
I am not sure if this the right group to post Radio (wireless) related questions. If not please suggest which one is good working group for radio certification either in Elsmar or any other.

So, this Europe address the 5 GHz requirements under EN 301 893.

Standards, under ADAPTIVITY[Channel Access Mechanism] asks to classify EUT as Frame Based or Load Based.

If your radio is following 802.11 protocol and utilizing a and n band, is the above classification dictated by radio manufacturer or by the 802.11 protocol?

Thank you in advance!

As this has not been picked up I'll give it a go!

EN 301 893 sets out testing for 5GHz communications equipment against the essential requirements of the European RED (Radio Equipment Directive). But, medical devices are subject to the Medical Device Directive. This product specific directive 'tops' the RED, so the essential requirements you must meet are those of the MDD.

Does this mean you don't have to pay any consideration to EN 301 893? No - but I would expect to buy a radio module that is already qualified, effectively leaving that to the manufacturer of the module.

When you come to EMC testing you will need to work with your test house to create a test plan that accommodates the communications module. Assuming it has already been qualified I would expect that EN 301 893 testing would not have to be repeated.

Edit:
Found this:

Frame Based Equipment (FBE): is equipment where the transmit/receive structure has a periodic timing with a
periodicity equal to the Fixed Frame Period

Load Based Equipment (LBE): equipment where the transmit/receive structure is not fixed in time but demand-driven

Definitions from ETSI.
These properties I would expect to be set by the radio module manufacturer.
