802.11n iyi IEEE inoshandiswa nehuwandu hweWi-Fi wireless network network, iyo yakagamuchirwa muna 2009. 802.11n yakagadzirirwa kutora hupfumi hwe 802.11a , 802.11b uye 802.11g Wi-Fi.
Key Wireless Technologies mu 802.11n
802.11n inoshandisa antenna dzakawanda dzisingabatsiri mumutsetse kutumira nekugamuchira deta. Izwi rinosanganiswa rokuti MIMO (Multiple Input, Multiple Output) rinoreva kukwanisa kwema 802.11n uye teknolojia yakadaro kufambisa zviratidzo zvakawanda zvepurogiramu. MIMO inowedzera zvose zviripo uye kuputika kwetambo isina wire.
Imwe nzira inoshandiswa ne 802.11n inosanganisira kuwedzera bandwidth. Sezvakanyorwa muna 802.11a / b / g, mumwe nomumwe .11njoni inoshandisa preset Wi-Fi chiteshi paanotumira. Chimwe nechimwe .11n channel inoshandisa hukuru hukuru hwepamusoro pane izvi zvakamboitika, uyewo kuwedzera kubuda kwe data.
802.11n Kuita
802.11n kushamwaridzana kunotsigira huwandu hwehutano hwomukati hwomukati kusvika ku 300 Mbps zvichienderana zvikuru nenhamba dzemafiriya asingasviki akabatanidzwa mumagetsi.
802.11n vs. Pre-N Network Equipment
Mumakore mashomanana apfuura vasati vasvika 802.11n vasati vashandurwa, hurumende yezvigadzirwa zvinoshandiswa zvinotengeswa zvinonzi pre-N kana zvinyorwa zveN n zvinyorwa zvichienderana nemashoko ekutanga ehurongwa. Iyi hardware inowirirana neiyo ino ma 802.11n gear, kunyange zvazvo firmware upgrades kune aya mafura akarenga angadiwa.
