Yini i-Wi-Fi ac?
I-IEEE 802.11ac izinga lenethiwekhi engenantambo yomndeni we-802.11, Yakhiwe yi-IEEE Standards Association futhi inikeza amanethiwekhi endawo angenantambo (WLANs) ngebhande le-5GHz, elivame ukubizwa nge-5G Wi-Fi (5th Generation of Wi- Fi).
Ithiyori, inganikeza ubuncane bomkhawulokudonsa ongu-1Gbps ekuxhumaneni kwe-LAN engenantambo yeziteshi eziningi, noma umkhawulokudonsa omncane wokudlulisela ongu-500Mbps ekuxhumekeni okukodwa.
I-802.11ac ilandela i-802.11n. Yamukela futhi inwebe umqondo wokuxhumana komoya osuselwe ku-802.11n, okuhlanganisa: ububanzi be-RF bandwidth (kufika ku-160MHz), imifudlana eminingi yendawo ye-MIMO (kufika ku-8), i-downlink yabasebenzisi abaningi be-MIMO (kufika ku-4), kanye nokuminyana okuphezulu ukuguquguquka (kufika ku-256-QAM).
Yini imbazo ye-Wi-Fi?
I-IEEE 802.11ax (Wi-Fi 6) yaziwa nangokuthi i-High-Efficiency Wireless(HEW).
I-IEEE 802.11ax isekela amabhendi efrikhwensi angu-2.4GHz kanye no-5GHz futhi ibuyela emuva ihambisana no-802.11 a/b/g/n/ac. Umgomo uwukusekela izimo zasendlini nezangaphandle, ukuthuthukisa ukusebenza kahle kwe-spectrum, kanye nokwandisa ukusebenza kwangempela izikhathi ezingu-4 ezindaweni eziminyene zabasebenzisi.
Izici eziyinhloko ze-ax ye-Wi-Fi:
- Ihambisana ne-802.11 a/b/g/n/ac
- 1024-QAM
- Ukhuphuka nomfula we-OFDMA
- Umfula u-MU-MIMO
- 4 izikhathi OFDM uphawu ubude besikhathi
- Ukuhlola Isiteshi Kwe-Adaptive Idle
