Ko te WiFi 7 (Wi-Fi 7) te paerewa Wi-Fi o te whakatipuranga e whai ake nei. E rite ana ki te IEEE 802.11, ka tukuna he paerewa hou kua whakahoutia, ko te IEEE 802.11be – Extremely High Throughput (EHT).
Mā te Wi-Fi 7 ka whakauruhia ngā hangarau pēnei i te whānui o te hononga 320MHz, te 4096-QAM, te Maha-RU, te mahi maha-hononga, te whakarei ake i te MU-MIMO, me te mahi tahi maha-AP i runga i te Wi-Fi 6, ka kaha ake te Wi-Fi 7 i te Wi-Fi 7. Nā te mea ka nui ake ngā tere whakawhiti raraunga a te Wi-Fi 6, ā, ka iti ake te whakaroa. E matapaetia ana ka tautoko te Wi-Fi 7 i te tere whakawhiti tae atu ki te 30Gbps, tata ki te toru ngā wā i te Wi-Fi 6.

1. He aha te Wi-Fi 7?
I te whanaketanga o te hangarau WLAN, ka nui haere te whakawhirinaki o ngā whānau me ngā umanga ki te Wi-Fi hei huarahi matua mō te uru atu ki te whatunga. I ngā tau tata nei, he nui ake ngā whakaritenga mō te tere me te whakaroa mō ngā tono hou, pērā i te ataata 4K me te 8K (tērā pea ka eke te tere tuku ki te 20Gbps), VR/AR, ngā kēmu (he iti iho i te 5ms te whakaritenga whakaroa), te tari mamao, me te huihuinga ataata ipurangi me te rorohiko kapua, me ētahi atu. Ahakoa kua arotahi te putanga hou o Wi-Fi 6 ki te wheako kaiwhakamahi i roto i ngā horopaki kiato teitei, kāore tonu e taea te whakatutuki i ngā whakaritenga teitei ake kua whakahuatia ake nei mō te tere me te whakaroa.

Hei whakatutuki i tēnei, kua tata te whakahaere paerewa IEEE 802.11 te tuku i tētahi paerewa hou kua whakahoutia, arā, ko te IEEE 802.11be EHT, arā, ko te Wi-Fi 7.
2. Te wā tuku o Wi-Fi 7
I whakatūria te rōpū mahi IEEE 802.11be EHT i te marama o Mei 2019, ā, kei te haere tonu te whakawhanaketanga o te 802.11be (Wi-Fi 7). Ka tukuna te paerewa kawa katoa i roto i ngā Tukunga e rua, ā, e matapaetia ana ka tukuna e te Release1 te putanga tuatahi i te tau 2021. E matapaetia ana ka tukuna e te Draft Draft1.0 te paerewa i te mutunga o te tau 2022; e matapaetia ana ka tīmata te Release2 i te tīmatanga o te tau 2022, ā, ka oti te tukunga paerewa i te mutunga o te tau 2024.
3. Wi-Fi 7 me Wi-Fi 6
I runga i te paerewa Wi-Fi 6, he maha ngā hangarau hou ka whakauruhia e Wi-Fi 7, ko te nuinga e whakaatuhia ana i roto i:
4. Ngā Āhuatanga Hou e Tautokona ana e Wi-Fi 7
Ko te whāinga o te kawa Wi-Fi 7 he whakapiki i te tere whakawhiti o te whatunga WLAN ki te 30Gbps, me te whakarato i ngā taurangi urunga iti-roa. Hei whakatutuki i tēnei whāinga, kua hangaia e te kawa katoa ngā huringa e rite ana ki te paparanga PHY me te paparanga MAC. Ki te whakatauritea ki te kawa Wi-Fi 6, ko ngā huringa hangarau matua i puta mai i te kawa Wi-Fi 7 koia ēnei:
Tautoko i te Whānuitanga Mōrahi 320MHz
He iti, he kī tonu hoki te whānuitanga kore-raihana i roto i ngā roopu auau 2.4GHz me te 5GHz. Ina whakahaerehia e te Wi-Fi ngā tono hou pēnei i te VR/AR, ka tūtaki pea ki te raruraru o te QoS iti. Hei whakatutuki i te whāinga o te tere whakawhiti mōrahi kāore i raro i te 30Gbps, ka haere tonu a Wi-Fi 7 ki te whakauru i te roopu auau 6GHz me te tāpiri i ngā momo whānui hou, tae atu ki te 240MHz tonu, te 160+80MHz kore-tonu, te 320 MHz tonu me te 160+160MHz kore-tonu. (Nau mai ki te aro ki te pūkete mana: te miihini whatunga a Aaron)
Tautoko i te Tikanga Maha-RU
I roto i te Wi-Fi 6, ka taea e ia kaiwhakamahi te tuku, te whiwhi rānei i ngā anga i runga i te RU motuhake kua tohaina, e tino whakawhāiti ana i te ngāwari o te whakaritenga rauemi whānuitanga. Hei whakaoti i tēnei raruraru, hei whakapai ake hoki i te whai huatanga o te whānuitanga, ka tautuhia e Wi-Fi 7 tētahi tikanga e āhei ai te tohatoha i ngā RU maha ki tētahi kaiwhakamahi kotahi. Ko te tikanga, hei whakataurite i te uaua o te whakatinanatanga me te whakamahinga o te whānuitanga, kua whakaritea e te kawa ētahi here mō te whakakotahitanga o ngā RU, arā: ka taea anake te whakakotahi i ngā RU iti (RU iti iho i te 242-Tone) me ngā RU iti, ā, ka taea anake te whakakotahi i ngā RU nui (RU nui ake i te 242-Tone, rite rānei ki te 242-Tone) me ngā RU nui, ā, kāore e whakaaetia kia whakaranua ngā RU iti me ngā RU nui.
Whakauruhia te hangarau whakarerekētanga 4096-QAM teitei ake
Ko te tikanga whakarerekētanga teitei rawa atu oIpurangi Ahokore 6ko te 1024-QAM, e 10 ngā moka o ngā tohu whakarerekētanga. Hei whakanui ake i te tere, ka whakauruhia e Wi-Fi 7 te 4096-QAM, kia 12 ngā moka o ngā tohu whakarerekētanga. I raro i te waehere kotahi, ka taea e te 4096-QAM o Wi-Fi 7 te whakatutuki i te pikinga tere 20% ki te whakataurite ki te 1024-QAM o Wi-Fi 6. (Nau mai ki te aro ki te pūkete mana: te miihini whatunga a Aaron)
Whakauruhia te tikanga hononga maha-hononga
Hei whakatutuki i te whakamahinga whai hua o ngā rauemi whāiti katoa e wātea ana, he hiahia nui kia whakatūria he tikanga whakahaere whāiti hou, he whakaritenga me te tuku i runga i te 2.4 GHz, 5 GHz me te 6 GHz. I tautuhia e te rōpū mahi ngā hangarau e pā ana ki te whakahiato maha-hononga, tae atu ki te hoahoa MAC o te whakahiato maha-hononga whakarei ake, te urunga hongere maha-hononga, te tuku maha-hononga me ētahi atu hangarau e pā ana.
Tautokohia ngā awa raraunga maha atu, te whakarei ake i te mahi MIMO
I roto i te Wi-Fi 7, kua piki ake te maha o ngā awa ā-wāhi mai i te 8 ki te 16 i roto i te Wi-Fi 6, e ai ki te ariā ka taea e tēnei te neke atu i te rua te tere tuku ā-tinana. Mā te tautoko i ngā awa raraunga maha atu ka puta mai hoki he MIMO tohatoha āhuatanga kaha ake, ko te tikanga ka taea te whakarato i ngā awa raraunga 16 ehara i te mea mā te pūwāhi urunga kotahi, engari mā ngā pūwāhi urunga maha i te wā kotahi, ko te tikanga me mahi tahi ngā AP maha tetahi ki tetahi kia mahi tahi ai.
Tautoko i te whakaritenga mahi tahi i waenga i ngā AP maha
I tēnei wā, i roto i te anga o te kawa 802.11, kāore i te nui te mahi tahi i waenga i ngā AP. Ko ngā mahi WLAN noa pēnei i te whakahāngai aunoa me te haereere atamai he āhuatanga kua tautuhia e te kaihoko. Ko te kaupapa o te mahi tahi i waenga i ngā AP he arotau noa i te kōwhiringa hongere, te whakarite i te kawenga i waenga i ngā AP, me ētahi atu, kia tutuki ai te kaupapa o te whakamahinga whai hua me te tohatoha taurite o ngā rauemi auau reo irirangi. Ko te whakaritenga whakarite i waenga i ngā AP maha i roto i te Wi-Fi 7, tae atu ki te whakamahere whakarite i waenga i ngā pūtau i te rohe wā me te rohe auau, te whakaritenga pokanoa i waenga i ngā pūtau, me te MIMO tohatoha, ka taea te whakaiti i te pokanoa i waenga i ngā AP, me te whakapai ake i te whakamahinga o ngā rauemi atanga hau.
;
He maha ngā huarahi hei whakarite i te whakaritenga i waenga i ngā AP maha, tae atu ki te C-OFDMA (Coordinated Orthogonal Frequency-Division Multiple Access), te CSR (Coordinated Spatial Reuse), te CBF (Coordinated Beamforming), me te JXT (Joint Transmission).
5. Ngā horopaki tono o te Wi-Fi 7
Mā ngā āhuatanga hou e whakaurua mai ana e Wi-Fi 7 ka tino whakapiki ake i te tere tuku raraunga, ā, ka iti ake te whakaroa, ā, ka nui ake te āwhina o ēnei painga ki ngā tono hou, penei:
- Rere ataata
- Hui Ataata/Reo
- Te petipeti ahokore
- Te mahi tahi ā-wā tonu
- Rorohiko Kapua/Taha
- Ipurangi Ahumahi o Ngā Mea
- AR/VR rumaki
- rongoā-ā-rorohiko taunekeneke
