AFAIK Orthogon uses high-order modulation to do that, in 30MHz channels both H and V polarisation. Atheros WiFi cards in most radios use 64QAM maximum, single polarisation (unless you use 2 cards) in 5, 10, 20 or 40MHz channels. All WiMax/802.16 profiles I've see use 64QAM maximum, single polarisation, and mostly on narrower channels (3.5, 7, 10MHz, though there is a 20MHz defined, not all chipsets can do it).
Higher order modulation, plus H and V polarisations over 30MHz is how Orthogon achieves high P2P throughput in the spectrum.
