[Bloat] Is 5/10MHz wifi bandwidth legal in 2.4GHz (half/quarter-clocking)?

2018-10-08 Thread bkil
If this is not the right forum to discuss, could you please point me in the right direction? After all, channel spacing is indeed 5MHz here. Although using a new raster instead of the 20MHz channel center frequencies would allow full utilization of the band (16 or 8 channels respectively), using t

I'm not aware of anywhere this would be illegal. Worst case you will need to reduce power by 3/6dB (10/5MHz) if there is a power spectral density limit in a given jurisdiction and max EIRP @ 20MHz is already at that limit. On Tue, 9 Oct 2018 at 06:48, bkil wrote: > > If this is not the right foru

Yes, that was my conclusion as well. There exist spectral masks of maximal allowed side lobes, but if you are transmitting signals narrower than that, the side lobes will be much below the limit. Spectral density in Hungary and some other countries allows for 10mW/MHz, meaning twice the power dens

I wouldn't be surprised if we could patch this mode to another common chipset other than Atheros. I understand that this is not a standard mode in 2.4GHz if reading the standard to the letter, but it is close enough. If it is legal to use it, as lots of devices support it, it would still be a grea
