content: 100Kbs max at the smallest channel size in a single antenna mode (SISO). This "HAY-LOW" stuff is an extension of the standard to allow for even smaller channels.     At larger channels its capable of some really decent throughput like upwards of ~40Mbs. And has the possibility of up to 4X4 channels (MIMO). Of course larger channel size means more interference and shorter range. Check out the IEEE database if your interested. And as much as I like Hackaday they have been consistently wrong about WIFI and other Part 15 spectrum in their write ups. They were trying to say encryption is illegal in the 900mhz spectrum!
