Hoʻohālikelike ʻia me 802.11ac, hāʻawi ʻo 802.11ax i kahi ʻenehana multiplexing spatial hou, hiki ke hoʻomaopopo koke i nā paio pili ea a pale aku iā lākou. I ka manawa like, hiki iā ia ke ʻike pono i nā hōʻailona interference a hōʻemi i ka walaʻau like ʻana ma o ka loiloi idle channel dynamic a me ka mana ikaika.
ʻO ke keakea, no laila e hoʻomaikaʻi nui ai i ka ʻike uila i nā hiʻohiʻona kiʻekiʻe e like me nā kikowaena, nā mokulele, nā paka, a me nā kahua pāʻani. Ua ʻōlelo ʻia ʻo ka awelika throughput hiki ke hiki i 4 mau manawa ma mua o ka maʻamau 802.11ac. Hoʻopuka ia i kahi modulation kiʻekiʻe a me coding scheme 1024QAM. Hoʻohālikelike ʻia me ka 256QAM kiʻekiʻe loa ma 802.11ac, ʻoi aku ka kiʻekiʻe o ka coding a me ka modulation efficiency. Hoʻonui ʻia ka helu hui o kēlā me kēia kahawai spatial bandwidth 80M mai 433Mbps a i 600.4Mbps. Ua hoʻonui ʻia ka nui o ka hui ʻana (160M bandwidth, 8 spatial streams) mai 6.9Gbps a hiki i 9.6Gbps, a ua hoʻonui ʻia ka helu hui kiʻekiʻe ma kahi o 40%. Hoʻohana ʻo 802.11ax i ka uplink a me ka downlink MU-MIMO a me ka uplink a me ka downlink OFDMA ʻenehana e lawe i ka hoʻoili like ʻana o nā mea hoʻohana he nui me nā kahawai spatial he nui a me nā subcarriers he nui i kēlā me kēia, e hoʻonui ai i ka pono o ka ea, hoʻemi i ka lohi o ka noi, a hōʻemi i ka pale ʻana i ka hakakā. Hāʻawi ia i ka hōʻoia hoʻouna ʻoi aku ka maikaʻi no nā hiʻohiʻona hoʻohana lehulehu.
