Pehea e helu ai i ka helu o Wi-Fi 6? ʻO ka mua, koho mai ka hoʻomaka a i ka hopena: E hoʻopili ʻia ka nui o ka hoʻouna ʻana e ka helu o nā kahawai spatial. ʻO ka helu o nā bits i hiki i kēlā me kēia subcarrier ke hoʻouna, ʻo ia ka helu o nā bits coded no kēlā me kēia subcarrier. ʻO ke kiʻekiʻe o ka helu coding, ʻoi aku ka maikaʻi. ʻehia ...

ʻO ka mea mua, e aʻo kākou e pili ana iā IEEE 802.11ax. I ka hui WiFi, kapa ʻia ʻo ia ʻo WiFi 6, ʻike ʻia hoʻi ʻo kahi ʻoihana pūnaewele ʻoihana uila kiʻekiʻe. ʻO ia kahi maʻamau maʻamau o ka ʻoihana ʻāina. Kākoʻo ʻo 11ax i nā pūʻulu 2.4GHz a me 5GHz, a hiki ke hoʻololi i hope me ka protoco maʻamau ...

802.11n pono e wehewehe kaawale. I kēia manawa, hoʻohana ka mākeke mainstream i kēia protocol no ka hoʻouna ʻana iā WiFi. ʻO 802.11n kahi protocol maʻamau maʻamau. He ʻenehana hana epoch. ʻO kona hiʻohiʻona e hoʻonui nui i ka nui o nā pūnaewele uea. I mea e hoʻomaikaʻi ai i ka ...

Nui nā manaʻo a me nā protocols e pili ana i nā pūnaewele uila. I mea e hāʻawi ai i ka manaʻo maikaʻi aʻe i kēlā me kēia, e wehewehe wau i ka hoʻokaʻawale ʻana. 1. E like me ka hoʻopili pūnaewele like ʻole, hiki ke hoʻokaʻawale ʻia nā ʻupena uila i: "WWAN" ke kū nei no ka "wireless wide area network. &...

1. Hoʻohana ʻia ʻo IEEE802.11b a me IEEE802.11g ma ke kāʻei alapine 2.4GHz. E wehewehe mākou i kēia mau protocol ʻelua ma ke ʻano mau i hiki iā mākou ke hoʻomaopopo i nā kūlana o nā protocol like ʻole. He kūlana maʻamau ka IEEE 802.11b no nā ʻuena pūnaewele wahi ʻole. ʻO 2.4GHz kona alapine lawe, a ...

E aʻo hou e pili ana iā IEEE 802.11a i ka protocol WiFi, ʻo ia ka protocol band 5G mua. 1) Ka wehewehe ʻana o ka protocol: ʻO IEEE 802.11a kahi maʻamau i hoʻoponopono hou ʻia o 802.11 a me kāna kūlana kumu, i ʻae ʻia i ka makahiki 1999. ʻO ka protocol kumu o ka maʻamau 802.11a ua like ia me ka maʻamau mua, ...
