FHSS, frequency hopping spread spectrum technology, ma lalo o ke ʻano o ka synchronization a me ka manawa like, e ʻae i nā hōʻailona i hoʻouna ʻia e nā mea lawe haiki o kahi ʻano kikoʻī (ʻo kēia ʻano kikoʻī he alapine kikoʻī, etc.) ma nā kihi ʻelua. No ka mea hoʻokipa me kahi ʻano kikoʻī ʻole, ka hop...

Ua noi ʻia ʻo OFDM ma IEEE802.11a. Ma muli o kēia ʻano o ka modulation, pono mākou e ʻike i ke ʻano o OFDM e hoʻomaopopo i nā protocols like ʻole. He aha ka OFDM? ʻO OFDM kahi ʻenehana modulation multi-carrier kūikawā. Ke manaʻo nei kēia ʻenehana e hoʻokaʻawale i kahi kahawai i kekahi mau sub-channels orthogonal, a ...

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. &...
