This is a re-transmission, my first send seems to have been corrcupted and 
combined with an earlier message.

Hi Chris & Treg world

There is a lot of debate at present on harmonised frequency bands for Radio 
products under the R&TTE D.  The basic argument is that, for reasons of 
differing terrain, evolution of national systems etc, there are many products 
required to perofrm the same function in different countries using different 
frequencies and sometimes, different modulation schemes.  That is a fact.

If we look at the wider picture, there are many new technologies for which CEPT 
(and in some cases ITU-R) have set-aside specific bands to be used by all 
member states.

There are also moves to free up bands occupied by old technology (i.e. moving 
police and public services away from the lower VHF bands and ceasing VHF TV 
transmissions etc.).  Where this occurrs, CEPT tries to formulate a new, 
pan-European use for these redundant bands and attempts to define harmonised 
usage.

Under the R&TTE Directive, a simple CE mark will allow you to place an item 
onto the market in any country where there is harmonised spectrum usage.  For 
products in countries where different bands / frequencies are allocated, your 
marking must (via an indicating code) show which countries it may be used in.  
You are not prevented from moving these goods around Europe but the user will 
be breaking the law if they attempt to use equipment so marked in a nation 
where the usage is invalid.

So, one must check with the ERO (and maybe CEPT) on which frequencies and 
schemes are harmonised and for products outside of this, the National radio 
authorities will be required to produce their spectrum allocation tables from 
which one will try to best engineer the product to meet as many target markets 
as possible and seek an ID code for the CE marking in each valid nation.

In cases of doubt (for radio products) an approval body will still exist but 
the role will be one of advising on compliance rather than actually certifying 
product.  One will be able to approach these bodies for a guidance decission on 
use of appropriate standards etc. for a multi-country case.

Please consider that this reply is very brief in terms of the degree of 
information to be conveyed by the directive, this response is aimed at 
definitions relating to harmonised spectrum usage only.  There are many other 
considerations to be applied under the directive.

I hope that this provides people with some basic understanding, the radio part 
of the directive is far more complex than te TTE part.
