He aha ka Wi-Fi ac?
ʻO IEEE 802.11ac kahi maʻamau o ka ʻohana 802.11, ua hoʻokumu ʻia ia e ka IEEE Standards Association a hāʻawi i nā ʻupena kūloko kūloko (WLAN) kiʻekiʻe ma o ka hui 5GHz, i kapa ʻia ʻo 5G Wi-Fi (5th Generation of Wi- Fi).
ʻO ka manaʻo, hiki iā ia ke hāʻawi i ka liʻiliʻi o ka bandwidth 1Gbps no ke kamaʻilio LAN uea ʻole he nui, a i ʻole ka bandwidth haʻahaʻa haʻahaʻa o 500Mbps no kahi pilina hoʻokahi.
ʻO 802.11ac ka hope o 802.11n. Hoʻopili a hoʻonui i ka manaʻo o ka lewa ea i loaʻa mai 802.11n, me ka: wider RF bandwidth (a hiki i 160MHz), ʻoi aku ka nui o nā kahawai spatial MIMO (a hiki i 8), downlink multi-user MIMO (a hiki i 4), a me ka kiʻekiʻe kiʻekiʻe. hoʻololi (hiki i ka 256-QAM).
He aha ke koʻi Wi-Fi?
ʻIke ʻia ʻo IEEE 802.11ax (Wi-Fi 6) ʻo High-Efficiency Wireless (HEW).
Kākoʻo ʻo IEEE 802.11ax i nā kaha alapine 2.4GHz a me 5GHz a paʻa i hope me 802.11 a/b/g/n/ac. ʻO ka pahuhopu ke kākoʻo i nā hiʻohiʻona o loko a me waho, hoʻomaikaʻi i ka pono spectrum, a hoʻonui i ka throughput maoli e 4 mau manawa i nā kaiapuni mea hoʻohana.
ʻO nā hiʻohiʻona nui Wi-Fi axe:
- Kūpono me 802.11 a/b/g/n/ac
- 1024-QAM
- Ma luna a ma lalo o OFDMA
- Iuka MU-MIMO
- 4 manawa ka lōʻihi o ka hōʻailona OFDM
- Adaptive Idle Channel Assessment
