Kei te hiahia koe ki te mōhio mēnā he pai ki tō hoa tāne te tākaro kēmu rorohiko? Tukua ahau kia tohatoha atu i tētahi tohutohu, ka taea e koe te tirotiro kei te hono tana rorohiko ki te taura whatunga, kāore rānei. Nā te mea he nui ngā whakaritenga a ngā tama mō te tere whatunga me te whakaroa i te wā e tākaro ana i ngā kēmu, ā, ko te nuinga o te WiFi kāinga o nāianei kāore e taea te mahi i tēnei ahakoa he tere te tere o te whatunga whānui, nō reira ko ngā tama e tākaro pinepine ana i ngā kēmu ka whiriwhiri i te urunga waea ki te whānui kia pai ai te taiao whatunga, kia tere ai hoki.
E whakaata ana hoki tēnei i ngā raruraru o te hononga WiFi: te roa o te whakaroa me te kore pumau, e kitea nuitia ana i roto i te take o te maha o ngā kaiwhakamahi i te wā kotahi, engari ka tino pai ake tēnei āhuatanga me te taenga mai o te WiFi 6. Nā te mea ko te WiFi 5, e whakamahia ana e te nuinga o te tangata, e whakamahi ana i te hangarau OFDM, ko te WiFi 6 ia e whakamahi ana i te hangarau OFDMA. Ka taea te whakaatu i te rerekētanga i waenga i ngā tikanga e rua:
I runga i tētahi rori e TAEA ana te whakauru i te kotahi waka anake, ka taea e te OFDMA te tuku i ngā taunga maha i te wā kotahi, ka whakakore i ngā rarangi me te kīkī, ka WHAKAPAI AKE I TE PAINGA ME te whakaiti i te whakaroa. Ka wehea e te OFDMA te hongere ahokore ki ngā hongere iti maha i roto i te rohe auau, kia taea ai e ngā kaiwhakamahi maha te tuku raraunga i te wā kotahi i ia wā, ka whakapai ake i te pai me te whakaiti i te whakaroa o te rarangi.
Kua rongonui a WIFI 6 mai i tōna whakarewatanga, nā te mea e hiahia ana te iwi kia nui ake ngā whatunga kāinga ahokore. Neke atu i te 2 piriona ngā teihana Wi-Fi 6 i tukuna i te mutunga o te tau 2021, e 50% neke atu rānei o ngā tukunga teihana Wi-Fi katoa, ā, ka piki taua tau ki te 5.2 piriona i te tau 2025, e ai ki te kamupene kaitātari IDC.
Ahakoa kua arotahi a Wi-Fi 6 ki te wheako kaiwhakamahi i roto i ngā horopaki kiato-rahi, kua puta ake ngā tono hou i ngā tau tata nei e hiahia ana kia nui ake te tere me te whakaroa, pērā i ngā ataata tino-teitei pērā i ngā ataata 4K me te 8K, te mahi mamao, te huihuinga ataata ipurangi, me ngā kēmu VR/AR. E kite ana hoki ngā kamupene hangarau nunui i ēnei raruraru, ā, ko Wi-Fi 7, e tuku ana i te tere tino nui, te kaha teitei me te whakaroa iti, kei te eke ki runga i te ngaru. Me tango te Wi-Fi 7 a Qualcomm hei tauira, ka kōrero mō ngā mea kua whakapai ake a Wi-Fi 7.
Wi-fi 7: Katoa mō te Whakaroa Iti
1. Te Whānuitanga o te Aratuku
Me titiro anō ki ngā rori. Ko te nuinga o te wā, ka tautoko a Wi-Fi 6 i ngā roopu 2.4ghz me te 5ghz, engari kua tohaina te rori 2.4ghz e ngā hangarau ahokore o mua me ētahi atu hangarau ahokore pērā i te Nihokikorangi, nō reira ka tino kikī. He whānui ake, he iti ake te kikī o ngā rori i te 5GHz i te 2.4ghz, ā, ka tere ake te tere me te nui ake o te kaha. Ka tautoko anō hoki a Wi-fi 7 i te roopu 6GHz i runga ake i ēnei roopu e rua, ka whakawhānui ake i te whānui o te hongere kotahi mai i te 160MHz o te Wi-Fi 6 ki te 320MHz (ka taea te kawe i ngā mea maha atu i te wā kotahi). I taua wā, ka eke te tere tuku tere o te Wi-Fi 7 ki runga ake i te 40Gbps, e whā ngā wā teitei ake i te Wi-Fi 6E.
2. Urunga Maha-hononga
I mua i te Wi-Fi 7, kotahi anake te huarahi i taea e ngā kaiwhakamahi te whakamahi i te huarahi e pai ana ki ā rātou hiahia, engari mā te otinga Wi-Fi 7 a Qualcomm ka panaia ake ngā rohe o te Wi-Fi: ā muri ake nei, ka taea e ngā roopu e toru te mahi tahi, ka whakaitihia te noho puku. Hei tāpiri, i runga i te mahi maha-hononga, ka taea e ngā kaiwhakamahi te hono atu mā roto i ngā hongere maha, ka whakamahia tēnei hei karo i te noho puku. Hei tauira, mēnā he waka kei runga i tētahi o ngā hongere, ka taea e te taputapu te whakamahi i tētahi atu hongere, ka iti ake te whakaroa. I taua wā, i runga i te wātea o ngā rohe rerekē, ka taea e te maha-hononga te whakamahi i ngā hongere e rua i te roopu 5GHz, i te huinga rānei o ngā hongere e rua i ngā roopu 5GHz me te 6GHz.
3. Hongere Whakakotahi
E ai ki te kōrero i runga ake nei, kua whakanuia te whānui o te Wi-Fi 7 ki te 320MHz (te whānui o te waka). Mō te roopu 5GHz, kāore he roopu 320MHz tonu, nō reira ko te rohe 6GHz anake ka taea te tautoko i tēnei aratau tonu. Mā te mahi hononga maha-hononga kotahi te whānui-teitei, ka taea te whakakotahi i ngā roopu auau e rua i te wā kotahi hei kohi i te putanga o ngā hongere e rua, arā, ka taea te whakakotahi i ngā tohu 160MHz e rua hei hanga i tētahi hongere whai hua 320MHz (te whānui whānui). Mā tēnei, ka taea hoki e tētahi whenua pēnei i tō tātou, kāore anō kia tohaina te whānuitanga 6GHz, te whakarato i tētahi hongere whai hua whānui hei whakatutuki i te putanga tino teitei i roto i ngā āhuatanga kapi.
4. 4K QAM
Ko te whakaōrite teitei rawa atu o Wi-Fi 6 ko te 1024-QAM, ko te Wi-Fi 7 ia ka taea te eke ki te 4K QAM. Mā tēnei, ka taea te whakanui ake i te tere tihi hei whakanui ake i te putanga raraunga me te kaha raraunga, ā, ka taea te eke ki te 30Gbps te tere whakamutunga, e toru ngā wā te tere o te WiFi 6 9.6Gbps o nāianei.
I roto i te poto, kua hangaia a Wi-Fi 7 hei whakarato i te tere tino tiketike, te kaha nui, me te iti o te whakaroa mā te whakanui ake i te maha o ngā ara e wātea ana, te whānui o ia waka e kawe ana i ngā raraunga, me te whānui o te ara haere.
Ka Whakawāteahia e te Wi-fi 7 te Ara mō te IoT Tere-Tino-maha-hononga
Ki tā te kaituhi whakaaro, ko te kaupapa matua o te hangarau Wi-Fi 7 hou ehara i te mea ko te whakapai ake i te tere tere o te taputapu kotahi anake, engari ko te aro nui atu ki te tuku tere tere i raro i te whakamahinga o ngā āhuatanga maha-kaiwhakamahi (urunga maha-ara), he mea e hangai ana ki te wā Ipurangi o ngā Mea e haere ake nei. Muri iho, ka kōrero te kaituhi mō ngā āhuatanga iot tino whai hua:
1. Ipurangi Ahumahi o Ngā Mea
Ko tētahi o ngā arai nui o te hangarau io i roto i te hanga ko te whānui o te hononga. Ko te nui ake o ngā raraunga ka taea te whakawhitiwhiti i te wā kotahi, ka tere ake, ka whai hua ake hoki te io. Mō te aroturuki kounga i roto i te Ipurangi Ahumahi o ngā Mea, he mea nui te tere o te whatunga ki te angitu o ngā tono wā-tūturu. Mā te awhina o te whatunga io tere-nui, ka taea te tuku i ngā whakatūpato wā-tūturu i te wā tika hei tere ake te whakautu ki ngā raruraru pēnei i ngā rahunga mīhini ohorere me ētahi atu whakararuraru, ka tino whakapai ake i te hua me te whai hua o ngā umanga hanga me te whakaiti i ngā utu koretake.
2. Rorohiko Tapa
I te mea kei te piki haere te hiahia o te tangata mō te tere o te urupare a ngā mīhini atamai, me te haumarutanga raraunga o te Ipurangi o ngā Mea, ka noho pōrearea te rorohiko kapua i ngā rā kei te heke mai. Ko te rorohiko taha ko te rorohiko i te taha kaiwhakamahi, e hiahia ana ki te kaha rorohiko teitei, me te tere tuku raraunga teitei hoki i te taha kaiwhakamahi.
3. AR/VR Rumaki
Me tere te urupare a te VR rumaki i runga anō i ngā mahi tūturu a ngā kaitākaro, ā, me nui rawa te whakaroa o te whatunga. Ki te mea he puhoi tonu te urupare a ngā kaitākaro, he tinihanga noa iho te rumaki. E matapaetia ana mā te Wi-fi 7 tēnei raruraru e whakaoti, ā, ka tere ake te whakamahi i te AR/VR rumaki.
4. Haumarutanga atamai
I te whanaketanga o te haumarutanga atamai, kei te piki haere te kounga o te pikitia e tukuna ana e ngā kāmera atamai, ko te tikanga kei te nui haere te raraunga hihiri e tukuna ana, ā, kei te piki haere hoki te tere o te whatunga me te whānui o te hononga. I runga i te LAN, ko te WIFI 7 pea te kōwhiringa pai rawa atu.
I te Mutunga
He pai te Wi-Fi 7, engari i tēnei wā, he rerekē ngā whakaaro o ngā whenua mō te whakaae kia uru atu ki te WiFi i te roopu 6GHz (5925-7125mhz) hei roopu kore raihana. Kāore anō kia tukuna e te whenua he kaupapa here mārama mō te 6GHz, engari ahakoa ko te roopu 5GHz anake e wātea ana, ka taea tonu e te Wi-Fi 7 te whakarato i te tere tuku mōrahi o te 4.3Gbps, ko te Wi-Fi 6 anake e tautoko ana i te tere tango teitei o te 3Gbps ina wātea te roopu 6GHz. Nō reira, e matapaetia ana ka nui haere te mahi a te Wi-Fi 7 i roto i ngā LAN tere-teitei a meake nei, ka āwhina i te maha atu o ngā taputapu atamai kia kore e mau i te taura.
