He palena hou ʻo Wi-fi 6E no ka ʻenehana Wi-Fi 6. ʻO ke ʻano o "E" no "Extended," e hoʻohui ana i kahi hui 6GHz hou i nā hui 2.4ghz a me 5Ghz mua. I ka hapaha mua o 2020, ua hoʻokuʻu ʻo Broadcom i nā hopena hoʻāʻo mua o Wi-Fi 6E a hoʻokuʻu i ka chipset wi-fi 6E mua o ka honua ʻo BCM4389. Ma ka lā 29 o Mei, ua hoʻolaha ʻo Qualcomm i kahi ʻāpana Wi-Fi 6E e kākoʻo ana i nā mea hoʻokele a me nā kelepona.
ʻO Wi-fi Fi6 e pili ana i ka hanauna 6 o ka ʻenehana pūnaewele uea ʻole, nona ka wikiwiki o ka pilina pūnaewele he 1.4 manawa i hoʻohālikelike ʻia me ka hanauna 5. ʻO ka lua, ʻo ka hana hou ʻenehana, ʻo ka hoʻohana ʻana o ka ʻenehana OFDM orthogonal Frequency division multiplexing a me ka ʻenehana MU-MIMO, hiki iā Wi-Fi 6 ke hāʻawi i ka ʻike pilina pūnaewele paʻa no nā polokalamu ʻoiai ma nā hiʻohiʻona pilina multi-device a mālama i ka hana pūnaewele maʻalahi.
Hoʻouna ʻia nā hōʻailona uea ʻole i loko o ke ʻano i laikini ʻole ʻia i kuhikuhi ʻia e ke kānāwai. Hoʻohana nā hanauna mua ʻekolu o nā ʻenehana uea ʻole, ʻo WiFi 4, WiFi 5 a me WiFi 6, i ʻelua mau kāʻei hōʻailona, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei. ʻO kekahi ka kāʻei 2.4ghz, kahi i maʻalahi i ka hoʻopilikia ʻia mai nā ʻano mea like ʻole, me nā mea nānā pēpē a me nā umu microwave. ʻO kekahi, ʻo ka kāʻei 5GHz, ua paʻa i kēia manawa e nā mea hana a me nā pūnaewele Wi-Fi kuʻuna.
ʻOi aku ka maʻalahi o ka mīkini mālama mana TWT (TargetWakeTime) i hoʻolauna ʻia e ka protocol WiFi 6 802.11ax, e ʻae ana i nā pōʻaiapuni mālama mana lōʻihi, a me ka hoʻonohonoho hiamoe multi-device. Ma keʻano laulā, loaʻa iā ia nā pono penei:
1. Kūkākūkā ka AP me ka hāmeʻa a wehewehe i kahi manawa kikoʻī e komo ai i ka pāpāho.
2. E hōʻemi i ka paio a me ka hoʻopili ʻana ma waena o nā mea kūʻai aku;
3. E hoʻonui nui i ka manawa hiamoe o ka hāmeʻa e hōʻemi i ka hoʻohana ʻana i ka mana.
Ua like ke ʻano o ka hoʻohana ʻana o Wi-Fi 6 me ko 5G. He kūpono ia no nā hiʻohiʻona wikiwiki, nui ka mana, a me ka latency haʻahaʻa, me nā hiʻohiʻona mea kūʻai aku e like me nā kelepona akamai, nā papa, nā kikowaena akamai hou e like me nā home akamai, nā noi wehewehe kiʻekiʻe loa, a me VR/AR. Nā hiʻohiʻona lawelawe e like me ka mālama olakino 3D mamao; Nā hiʻohiʻona kiʻekiʻe e like me nā kahua mokulele, nā hōkele, nā wahi nui, a pēlā aku. Nā hiʻohiʻona pae ʻoihana e like me nā hale hana akamai, nā hale kūʻai unmanned, a pēlā aku.
I hoʻolālā ʻia no kahi honua kahi e pili ai nā mea āpau, hoʻonui nui ʻo Wi-Fi 6 i ka hiki ke hoʻoili a me ka wikiwiki ma ka manaʻo ʻana i nā helu uplink a downlink symmetrical. Wahi a ka hōʻike a Wi-Fi Alliance, ʻo ka waiwai hoʻokele waiwai honua o WiFi he 19.6 trillion kālā US i ka makahiki 2018, a ua manaʻo ʻia e hiki aku ka waiwai hoʻokele waiwai ʻoihana honua o WiFi i 34.7 trillion kālā US ma ka makahiki 2023.
Ua ulu ikaika ka ʻāpana ʻoihana o ka mākeke WLAN i ka hapaha ʻelua o 2021, e ulu ana he 22.4 pakeneka makahiki ma luna o ka makahiki i $1.7 biliona, e like me ka hōʻike hahai hapaha hapaha o IDC's global Wireless Local Area Networks (WLAN). Ma ka ʻāpana mea kūʻai aku o ka mākeke WLAN, ua emi ka loaʻa kālā he 5.7% i ka hapaha i $2.3 biliona, e hopena ana i ka piʻi ʻana o ka loaʻa kālā he 4.6% makahiki ma luna o ka makahiki i ka hapaha ʻelua o 2021.
I waena o lākou, ua hoʻomau ka ulu ʻana o nā huahana Wi-Fi 6 ma ka mākeke mea kūʻai aku, e helu ana i 24.5 pakeneka o ka loaʻa kālā holoʻokoʻa o ka ʻāpana mea kūʻai aku, mai 20.3 pakeneka i ka hapaha mua o 2021. ʻO nā wahi komo WiFi 5 nō ka hapa nui o ka loaʻa kālā (64.1%) a me nā hoʻouna ʻāpana (64.0%).
Ua ikaika mua ka Wi-fi 6, akā me ka laha ʻana o nā home akamai, ke piʻi nui nei ka nui o nā hāmeʻa i loko o ka home e hoʻopili ana i ka uea ʻole, kahi e hoʻoulu ai i ka paʻa nui ʻana ma nā hui 2.4ghz a me 5GHz, e paʻakikī ai i ka Wi-Fi ke hoʻokō i kona hiki piha.
Ua hōʻike ka wānana a IDC no ka nui o nā pilina Pūnaewele o nā Mea ma Kina i loko o ʻelima mau makahiki ʻo nā pilina uea a me ka WiFi ka hapa nui loa o nā ʻano pilina āpau. Ua hōʻea ka nui o nā pilina uea a me WiFi i 2.49 biliona i ka makahiki 2020, ʻo ia hoʻi he 55.1 pakeneka o ka huina, a ua manaʻo ʻia e hōʻea i 4.68 biliona i ka makahiki 2025. I loko o ka nānā wikiō, ka iot ʻoihana, ka home akamai a me nā hiʻohiʻona ʻē aʻe he nui, e pāʻani mau ana ka uea a me ka WiFi i kahi kuleana koʻikoʻi. No laila, he mea pono loa ka hoʻolaha a me ka hoʻohana ʻana o WiFi 6E.
ʻAʻole hana nui ka hui 6Ghz hou, e hāʻawi ana i ka spectrum hou aʻe. No ka laʻana, hiki ke hoʻokaʻawale ʻia ke alanui kaulana i 4 mau ala, 6 mau ala, 8 mau ala, a pēlā aku, a ua like ka spectrum me ke "ala" i hoʻohana ʻia no ka hoʻoili ʻana i nā hōʻailona. ʻOi aku ka nui o nā kumuwaiwai spectrum, ʻo ia hoʻi nā "ala" hou aʻe, a e hoʻomaikaʻi ʻia ka pono o ka hoʻoili ʻana.
I ka manawa like, ua hoʻohui ʻia ke kāʻei 6GHz, e like me ke alahaka ma luna o ke alanui i piha i ka poʻe, e hoʻomaikaʻi hou aku ana i ka pono o ka halihali holoʻokoʻa o ke alanui. No laila, ma hope o ka hoʻolauna ʻana o ke kāʻei 6GHz, hiki ke hoʻokō ʻia nā ʻano hoʻolālā hoʻokele spectrum like ʻole o Wi-Fi 6 me ka ʻoi aku ka maikaʻi a me ka piha, a ʻoi aku ka kiʻekiʻe o ka pono o ke kamaʻilio ʻana, no laila e hāʻawi ana i ka hana kiʻekiʻe, ka throughput nui a me ka latency haʻahaʻa.
Ma ka pae noi, hoʻoponopono maikaʻi ʻo WiFi 6E i ka pilikia o ka paʻa nui ʻana ma nā kāʻei 2.4ghz a me 5GHz. Ma hope o nā mea a pau, ʻoi aku ka nui o nā polokalamu uea ʻole ma ka home i kēia manawa. Me 6GHz, hiki i nā polokalamu e koi ana i ka pūnaewele ke hoʻopili i kēia kāʻei, a me 2.4ghz a me 5GHz, hiki ke hoʻokō ʻia ka hiki nui loa o WiFi.
ʻAʻole wale kēlā, akā loaʻa i ka WiFi 6E kahi hoʻonui nui ma ka chip o ke kelepona, me ka wikiwiki kiʻekiʻe o 3.6Gbps, ʻoi aku ma mua o ka pālua o ka chip WiFi 6. Eia kekahi, ʻoi aku ka haʻahaʻa o ka lohi o ka WiFi 6E ma lalo o 3 milliseconds, ʻoi aku ma mua o 8 mau manawa haʻahaʻa ma mua o ka hanauna ma mua i ke kaiapuni paʻa. Hiki iā ia ke hāʻawi i kahi ʻike maikaʻi aʻe i nā pāʻani, ke wikiō HIGH-DEFINITION, ka leo a me nā ʻano ʻē aʻe.
