I am not sure about this. But if equipment that comply with FCC standard allow to use 40MHz, I think we can because, for example Translated rule for 2.4GHz says === Rules for communication equipment that use 2.400-2.500 GHz band: Communication equipment that use 2.400-2.500 GHz band must stated and comply with one of following standards: 2.1.2.1 ?EN 300 328-2 ?: ?Electromagnetic compatibility and Radio spectrum Matters (ERM); Wideband Transmission systems; Data transmission equipment operating in the 2,4 GHz ISM band and using spread spectrum modulation techniques; Part 2: Harmonized EN covering essential requirements under article 3.2 of R&TTE Directive 2.1.2.2 ?FCC Part 15.247 : ?Code of Federal Regulations (USA); Title 47 Telecommunication; Chapter 1 Federal Communications Commission; Part 15 Radio Frequency Devices; Subpart C ?
