Ki te whakatauritea ki ngā whakatupuranga o mua o te hangarau WiFi, ko ngā āhuatanga matua o te whakatupuranga hou o WiFi 6 ko:
Ki te whakatauritea ki te whakatupuranga o mua o te 802.11ac WiFi 5, kua piki ake te tere tuku mōrahi o te WiFi 6 mai i te 3.5Gbps o mua ki te 9.6Gbps, ā, kua piki ake te tere ariā tata ki te 3 ngā wā.
Mō ngā roopu auau, ko te WiFi 5 anake e pā ana ki te 5GHz, ko te WiFi 6 ia e pā ana ki te 2.4/5GHz, e kapi katoa ana i ngā taputapu tere-iti me ngā taputapu tere-tiketike.
Mō te aratau whakarerekētanga, ka tautoko a WiFi 6 i te 1024-QAM, he teitei ake tēnei i te 256-QAM o WiFi 5, ā, he nui ake te kaha raraunga, ko te tikanga he tere ake te tuku raraunga.
Whakaroa iti iho
Ehara i te mea ko te WiFi 6 he pikinga ake i ngā tere tukuake me te tango noa iho, engari he whakapainga nui hoki i te noho pukumahi o te whatunga, e āhei ai te maha atu o ngā taputapu ki te hono atu ki te whatunga ahokore me te whai wheako hononga tere-teitei pumau, ko te take nui o tēnei ko ngā hangarau hou o MU-MIMO me OFDMA.
E tautoko ana te paerewa WiFi 5 i te hangarau MU-MIMO (whakauru maha-kaiwhakamahi maha-putanga), e tautoko ana i te hononga-whakamuri anake, ā, ka taea anake te wheako i tēnei hangarau i te wā e tango ana i ngā ihirangi. E tautoko ana a WiFi 6 i te hononga-whakamuri me te hononga-whakamuri MU-MIMO, ko te tikanga ka taea te wheako i te MU-MIMO i te wā e tukuatu ana me te tango raraunga i waenga i ngā taputapu pūkoro me ngā pouara ahokore, ka whakapai ake i te whakamahinga whānui o ngā whatunga ahokore.
Kua whakapikihia te maha mōrahi o ngā awa raraunga ā-wāhi e tautokona ana e te WiFi 6 mai i te 4 i roto i te WiFi 5 ki te 8, arā, ka taea e ia te tautoko i te 8×8 MU-MIMO mōrahi, koinei tētahi o ngā take nui mō te pikinga nui o te tere o te WiFi 6.
Ka whakamahia e te WiFi 6 te hangarau OFDMA (Orthogonal Frequency Division Multiple Access), he putanga whanaketanga o te hangarau OFDM e whakamahia ana i roto i te WiFi 5. Ka whakakotahihia e ia te hangarau OFDM me te FDMA. Whai muri i te whakamahinga o te OFDM hei huri i te hongere hei kawe matua, ka taea e ētahi kawe iti te tohatoha i te hongere kotahi mā te hangarau tuku raraunga tuku me te tuku raraunga, ka taea ai e ngā taputapu maha te uru atu, me te wā urupare poto ake me te whakaroa iti ake.
Hei tāpiritanga, ka whakamahia e WiFi 6 te tikanga tuku Long DFDM Symbol hei whakanui ake i te wā tuku o ia kaikawe tohu mai i te 3.2 μs i roto i te WiFi 5 ki te 12.8 μs, hei whakaiti i te tere ngaronga mōkihi me te tere tuku anō, ā, hei whakapai ake i te pumau o te tuku.
Te kaha nui ake
Ka whakauruhia e WiFi 6 te tikanga Tae BSS, e tohu ana i ia taputapu e hono ana ki te whatunga, me te tāpiri i ngā tapanga e rite ana ki ōna raraunga i te wā kotahi. I te wā e tuku raraunga ana, he wāhitau e rite ana, ā, ka taea te tuku tika atu me te kore e pōhēhē.
Mā te hangarau MU-MIMO maha-kaiwhakamahi ka taea e ngā pūrua maha te tohatoha i te hongere o te whatunga rorohiko i te wā kotahi, kia taea ai e ngā waea pūkoro/rorohiko maha te tirotiro i te Ipurangi i te wā kotahi. I te whakakotahitanga me te hangarau OFDMA, ka taea e ia hongere i raro i te whatunga WiFi 6 te tuku raraunga tino whai hua, ka whakapai ake i te wheako whatunga maha-kaiwhakamahi i roto i te tirohanga ka taea te whakatutuki pai ake i ngā whakaritenga o ngā wāhi wera WiFi, te whakamahinga maha-kaiwhakamahi, ā, kāore e ngāwari te whakatio, ā, he nui ake te kaha.
Haumaru ake
Mena me whai tiwhikete WiFi 6 (pouara ahokore) e te WiFi Alliance, me whakamahi i te kawa haumarutanga WPA 3, he kawa haumaru ake tēnei.
I te tīmatanga o te tau 2018, i tukuna e te WiFi Alliance te whakatupuranga hou o te kawa whakamunatanga WiFi, arā, ko te WPA 3, he putanga whakapai ake tēnei o te kawa WPA 2 e whakamahia whānuitia ana. Kua whakapaitia ake te haumarutanga, ā, ka taea te ārai pai ake i ngā whakaekenga kaha-kino me te pakaru kaha-kino.
te penapena hiko nui ake
Ka whakauruhia e WiFi 6 te hangarau TARget Wake Time (TWT), e āhei ai te whakamahere hohe i te wā whakawhitiwhiti kōrero i waenga i ngā taputapu me ngā pouara ahokore, e whakaiti ana i te whakamahinga o ngā pūihi whatunga ahokore me te wā rapu tohu, e taea ai te whakaiti i te whakapaunga hiko ki tētahi taumata, me te whakapai ake i te roa o te pākahiko o te taputapu.
Ka whakaratohia e HUANET te WIFI 6 ONT, ki te hiahia koe, whakapā mai ki a mātou.
