Kodi Wi-Fi ac ndi chiyani?
IEEE 802.11ac ndi mulingo wopanda zingwe wa banja la 802.11, idapangidwa ndi IEEE Standards Association ndipo imapereka ma network opanda zingwe amderali (WLANs) kudzera mu band ya 5GHz, yomwe imadziwika kuti 5G Wi-Fi (5th Generation of Wi- Fi).
Lingaliro, limatha kupereka bandwidth ya 1Gbps yolumikizana ndi ma LAN angapo opanda zingwe, kapena bandwidth yochepera ya 500Mbps pakulumikizana kumodzi.
802.11ac ndiye wolowa m'malo wa 802.11n. Imatengera ndikukulitsa lingaliro la mawonekedwe a mpweya ochokera ku 802.11n, kuphatikiza: bandwidth yotalikirapo ya RF (mpaka 160MHz), mitsinje yambiri ya MIMO (mpaka 8), downlink yogwiritsa ntchito ambiri MIMO (mpaka 4), komanso kachulukidwe kakang'ono. kusinthasintha (mpaka 256-QAM).
Kodi ax ya Wi-Fi ndi chiyani?
IEEE 802.11ax (Wi-Fi 6) imadziwikanso kuti High-Efficiency Wireless (HEW).
IEEE 802.11ax imathandizira 2.4GHz ndi 5GHz ma frequency band ndipo imagwira kumbuyo kumbuyo ndi 802.11 a/b/g/n/ac. Cholinga chake ndikuthandizira zochitika zamkati ndi zakunja, kuwongolera magwiridwe antchito, ndikuwonjezera zotulutsa zenizeni ndi nthawi zinayi m'malo owundana ndi ogwiritsa ntchito.
Zofunikira zazikulu za Wi-Fi ax:
- Zogwirizana ndi 802.11 a/b/g/n/ac
- 1024-QAM
- Kumtunda ndi kumunsi kwa OFDMA
- Mtsinje wa MU-MIMO
- Nthawi 4 nthawi ya chizindikiro cha OFDM
- Adaptive Idle Channel Assessment
Zogwirizana nazo : Bluetooth wifi combo module
