Mavidiyo ndi masewera othamanga amapindula kuchokera ku ma routers apanyumba
Mabotolo a Broadband amapangidwa kuti akhale ovuta pomanga makompyuta a kunyumba, makamaka kwa nyumba zomwe zili ndi intaneti yothamanga kwambiri . Kuwonjezera pa kupanga zotheka kuti zipangizo zonse zamagetsi pakhomo zizigawidwa ndi intaneti, ma routi akuluakulu amathandizanso kugawidwa kwa mafayi, makina osindikiza, ndi zinthu zina pakati pa makompyuta a kunyumba ndi zipangizo zina zamagetsi.
Galimoto yothamanga yapamwamba imagwiritsa ntchito muyezo wa Ethernet wothandizira wired. Mabomba oyendetsa mabwalo ambiri amatenga makina a Ethernet omwe ankathamanga pakati pa router, modem ya broadband, ndi kompyuta iliyonse pamtanda wa nyumba. Mawutchi atsopano opangira mabanki amatha kugwirizana kwa intaneti pa modem. Amagwirizanitsa ndi zipangizo m'nyumba mosagwiritsa ntchito miyezo ya Wi-Fi .
Mitundu yambiri ya ma router imapezeka, ndipo iliyonse imakhala ndi muyezo wapadera. Omasulira omwe amagwiritsira ntchito mowonjezereka wamakono alipo pa mtengo wapamwamba kusiyana ndi iwo omwe ali okalamba, koma akuphatikizapo zinthu zabwino. Zomwe zilipo tsopano ndi 802.11ac. Zinayambika ndi 802.11n ndi-ngakhale kale-802.11g. Malamulo onsewa adakalipobe m'magalimoto, ngakhale okalamba ali ndi malire.
802.11ac othamanga
802.11ac ndiyeso yatsopano ya Wi-Fi. Ma router onse 802.11ac ali ndi zida zatsopano ndi mapulogalamu kusiyana ndi kuchitapo kanthu koyambirira ndipo ali angwiro kwapakati mpaka kumidzi yayikulu kumene kuliwiro ndi kudalirika n'kofunikira.
Router 802.11ac imagwiritsa ntchito makina opanga mafilimu osagwiritsa ntchito makina awiri ndipo imagwira ntchito pa GHz ya 5 GHz, yomwe imatha kufika pa 1 Gb / s, kapena kugwiritsidwa ntchito limodzi kwa 500 Mb / s pa 2.4 GHz. Kufulumira kumeneku ndi koyenera kumaseĊµera, mafilimu a HD akukhamukira, ndi zofunikira zina zamtundu wa bandwidth .
Makhalidwe amenewa adagwiritsa ntchito zipangizo zamakono mu 802.11n koma kuwonjezera mphamvu mwa kulola RF bandwidth ngati 160 MHz ndikuthandizira mitsinje eyiti yambiri yowonjezera (MIMO) ndi makina ochepa a MIMO makampani osiyanasiyana.
Njira yamakono 802.11ac imagwirizana ndi 802.11b, 802.11g, ndi 802.11n hardware, kutanthauza kuti ngakhale router 802.11ac imagwira ntchito ndi zipangizo zamakina zomwe zimathandiza 802.11ac muyezo, zimaperekanso mwayi wogwiritsa ntchito makina omwe amathandiza 802.11b / g / n.
802.11n Routers
IEEE 802.11n, omwe nthawi zambiri amatchedwa 802.11n kapena Wireless N), amalowetsa ma teknoloji okalamba 802.11a / b / g ndikuwonjezera ma deta pamagulu awo pogwiritsa ntchito makina osiyanasiyana, kupeza mabala ochokera 54 Mb / s mpaka 600 Mb / s , malinga ndi chiwerengero cha ma radio mu chipangizochi.
Mabotolo 802.11n amagwiritsa ntchito mitsinje inayi pa mzere wa 40 MHz ndipo akhoza kugwiritsidwa ntchito pafupipafupi 2.4 GHz kapena 5 GHz band frequency.
Mabotolowa ali kumbuyo akugwirizana ndi 802.11g / b / ma routers.
802.11g Othandizira
Masewu 802.11g ndipamwamba zatsopano zamakina a Wi-Fi, kotero maulendo amenewa nthawi zambiri amakhala otsika mtengo. Mawotchi 802.11g ndi abwino m'nyumba zomwe maulendo akufulumira sakufunika.
Chombo cha 802.11g chikugwira ntchito pa bandikiti ya 2.4 GHz ndipo chimathandizira chiwerengero chachikulu cha 54 Mb / s, koma kawirikawiri chiri ndi kuyeza kwapakati pa 22 Mb / s. Mawendowa ndi abwino kwambiri pazamasewero ofunikira pa intaneti ndi kufotokozera kwasankhulidwe ma TV.
Mgwirizanowu umagwirizana kwambiri ndi zipangizo zakale za 802.11b , koma chifukwa chothandizira kulandira cholowa, kuperewera kwachepetsedwa ndi pafupifupi 20 peresenti poyerekeza ndi 802.11a .
