Yes, well, the rules probably pre-date Bluetooth and similar add-ons and should be revised. The 'highest frequency' was considered in the context of the data processing, not wireless links. This also affects CISPR 22 and CISPR 32, and the Generics, too, I think, that all refer to 'highest frequency', but will anyone notice? -- OOO - Own Opinions Only.
