This is interesting. The manual for the wireless access point I purchased yesterday says the following:
> INTENDED USE. This device is a 2.4 GHz wireless LAN transceiver,
> intended for indoor home and office use in all EU and EFTA member states.
> POTENTIAL RESTRICTIVE USE. This device is a 2.4 GHz wireless LAN
> transceiver, intended for indoor home and office use in all EU and EFTA
> member states, except in France, Belgium and Italy where restrictive use
> In Italy the end-user should apply for a license at the national
> spectrum authorities in order to obtain an authorization to use the
> device for setting up outdoor radio links.
> In Belgium there is a restriction in outdoor use. The frequency range in
> which outdoor operation in Belgium is permitted is 2460-2483.5 MHz,
> This device may not be used for setting up outdoor radio links in
> France. For more information see http://www.anfr.fr/ and/or
So it appears it's up to the end user to configure the device correctly in Belgium... but no hint as to the permitted channels is given, the user is expected to work them out from the frequency himself!
