Wi-Fi ac yog dab tsi?
IEEE 802.11ac yog ib lub wireless network tus qauv ntawm 802.11 tsev neeg, Nws tau tsim los ntawm IEEE Standards Association thiab muab siab-throughput wireless hauv zos networks (WLANs) los ntawm 5GHz band, feem ntau hu ua 5G Wi-Fi (5th Generation of Wi- Fi).
Txoj kev xav, nws tuaj yeem muab qhov tsawg kawg nkaus ntawm 1Gbps bandwidth rau ntau lub chaw nres tsheb wireless LAN kev sib txuas lus, lossis qhov tsawg kawg nkaus kis tau tus mob bandwidth ntawm 500Mbps rau ib qho kev sib txuas.
802.11ac yog tus ua tiav ntawm 802.11n. Nws txais thiab txuas ntxiv lub tswv yim ntawm huab cua cuam tshuam los ntawm 802.11n, suav nrog: dav RF bandwidth (txog 160MHz), ntau MIMO spatial kwj (txog 8), downlink multi-neeg siv MIMO (txog 4), thiab high-density modulation (txog 256-QAM).
Dab tsi yog Wi-Fi ax?
IEEE 802.11ax (Wi-Fi 6) tseem hu ua High-Efficiency Wireless (HEW).
IEEE 802.11ax txhawb 2.4GHz thiab 5GHz zaus bands thiab rov qab tau tshaj 802.11 a/b/g/n/ac. Lub hom phiaj yog los txhawb cov xwm txheej sab hauv tsev thiab sab nraum zoov, txhim kho kev ua haujlwm ntawm spectrum, thiab nce qhov tseeb ntawm 4 npaug ntawm cov neeg siv khoom hnyav.
Wi-Fi ax lub ntsiab nta:
- Tau tshaj 802.11 a/b/g/n/ac
- 1024-QAM
- Upstream thiab downstream OFDMA
- Upstream MU-MIMO
- 4 zaug OFDM cim lub sijhawm
- Adaptive Idle Channel Assessment
Yam khoom: Bluetooth wifi combo module
