Yintoni iWi-Fi ac?
IEEE 802.11ac ngumgangatho wothungelwano olungenazingcingo lwe-802.11 yosapho, Yaqulunqwa yi-IEEE Standards Association kwaye ibonelela ngothungelwano lwengingqi olungenazingcingo (WLANs) ngokusebenzisa ibhendi ye-5GHz, edla ngokubizwa ngokuba yi-5G Wi-Fi (5th Generation of Wi- Fi).
Ithiyori, inokubonelela ubuncinci be-bandwidth ye-1Gbps ye-multiple-station wireless LAN yonxibelelwano, okanye ubuncinane be-bandwidth ye-500Mbps yoqhagamshelwano olulodwa.
I-802.11ac ngumlandeli we-802.11n. Yamkela kwaye yandise ingcamango yojongano lomoya oluphuma kwi-802.11n, kubandakanywa: ububanzi be-RF (ukuya kwi-160MHz), imijelo yendawo ye-MIMO (ukuya kwi-8), i-downlink yabasebenzisi abaninzi be-MIMO (ukuya kwi-4), kunye noxinzelelo oluphezulu. ukumodareyitha (ukuya kuthi ga kwi-256-QAM).
Yintoni i-ax ye-Wi-Fi?
IEEE 802.11ax (Wi-Fi 6) ikwabizwa ngokuba yi-High-Efficiency Wireless (HEW).
IEEE 802.11ax ixhasa i-2.4GHz kunye ne-5GHz iibhendi zamaza kwaye ibuyela ngasemva iyahambelana ne-802.11 a/b/g/n/ac. Injongo kukuxhasa iimeko zangaphakathi kunye nezangaphandle, ukuphucula ukusebenza kakuhle kwe-spectrum, kunye nokwandisa ukuphumelela kwangempela ngamaxesha e-4 kwiindawo ezixineneyo zabasebenzisi.
Iimpawu eziphambili ze-ax ye-Wi-Fi:
- Iyahambelana ne-802.11 a/b/g/n/ac
- 1024-QAM
- Phezulu nasezantsi kwe-OFDMA
- Phezulu kwe-MU-MIMO
- Amaxesha ama-4 ubude besimboli ye-OFDM
- UVavanyo lweSitishi se-Adaptive Idle
Imveliso eyeleleneyo : Imodyuli yeBluetooth wifi combo
