802.11ax Kufotokozera

WiFi6 yatsopano imathandizira 802.11ax mode, ndiye pali kusiyana kotani pakati pa 802.11ax ndi 802.11ac mode?

Poyerekeza ndi 802.11ac, 802.11ax ikupereka ukadaulo watsopano wochulukitsa malo, womwe umatha kuzindikira ndikubwezeretsanso mikangano yamawonekedwe amlengalenga. Pakadali pano, imatha kuzindikira zikwangwani zosokoneza bwino ndikuchepetsa kusokonezedwa kwaphokoso pogwiritsa ntchito kuwunika kosagwira ntchito komanso kuwongolera mphamvu kwamphamvu. Chifukwa chake, zochitika zopanda zingwe pamasiteshoni, ma eyapoti, m'mapaki, mabwalo amasewera ndi zochitika zina zokhala ndi kachulukidwe kakang'ono zimawongoleredwa bwino, ndipo kutulutsa kwapakati kumanenedwa kuti kumafika nthawi 4 kuposa muyezo wa 802.11ac. Ikubweretsa dongosolo lapamwamba losinthira khodi 1024QAM. Poyerekeza ndi 256QAM yapamwamba kwambiri mu 802.11ac, kusinthasintha kwa ma encoding ndikokwera kwambiri. Mlingo wolumikizana wamtundu uliwonse wa 80M bandwidth ukuwonjezeka kuchokera ku 433Mbps mpaka 600.4Mbps. 8 mitsinje yapakatikati) idakwera kuchokera ku 6.9Gbps ​​kupita ku 9.6Gbps, ndipo chiwopsezo chapamwamba kwambiri chawonjezeka ndi pafupifupi 40%. 802.11ax imagwiritsa ntchito matekinoloje okwera ndi otsika a MU-MIMO ndi matekinoloje okwera ndi otsika a OFDMA motsatana kuti apereke kufalitsa kwa ogwiritsa ntchito angapo omwe ali ndi mitsinje yamitundu yambiri ndi ma subcarriers angapo, zomwe zimawonjezera magwiridwe antchito a mawonekedwe a mpweya, zimachepetsa kuchedwa kwa ntchito, komanso amachepetsa kupewedwa kwa mikangano kwa ogwiritsa ntchito, ndikupereka chitsimikizo chabwinoko chotumizira muzochitika za ogwiritsa ntchito ambiri.
