B is the 99% emission bandwidth in megahertz. The e.i.r.p. spectral density shall not exceed 10 dBm in any 1.0 MHz band. However, for < 20 MHz, like 5 or 10, which we in theory do support, you can't use that much due to the spectral density requirement. It seems possible that that's where the 17 dBm came from, since 10 + 10 log10(5) is about 17. johannes _______________________________________________ wireless-regdb mailing list wireless-regdb@lists.infradead.org http://lists.infradead.org/mailman/listinfo/wireless-regdb
