In France, outdoor operation of a wireless device is only permitted using the 2.4 to 2.454 GHz

frequency band. The BlackBerry device only operates in infrastructure mode and as a result, will

not transmit in the 2.4 to 2.45 GHz frequency band other than to communicate with a wireless

access point.

Information for the implementation of the 5 GHz frequency band can be found in the Official

Journal of the European Union Commission Decision of 12 February 2007 wherein it states that

in the frequency band 5.150 to 5.350 GHz Wireless Access Systems (WAS) including Radio Local

Area Networks (RLANs) shall be restricted to indoor use. Since the creation of a network is within

the domain of the wireless access point and the access point is a master device, the BlackBerry

device never initiates the creation of a network or attaches to a network in ad-hoc mode in the

5.150 to 5.350 GHz frequency band.
