Ukudlala kwevidiyo nokugembula kusuka kuma-routers asekhaya okusheshayo
Ama-router Broadband aklanyelwe kalula ekusethekeni amanethiwekhi asekhaya, ikakhulukazi emakhaya ane -intanethi ye-intanethi yesevisi . Ngaphandle kokuthi kwenzeke ukuthi wonke amadivaysi kagesi ekhaya ahlanganyele uxhumano lwe-intanethi, ama-router broadband nawo akwazi ukwabelana ngamafayela, amaphrinta, nezinye izinsiza phakathi kwamakhompyutha asekhaya nakwamanye amadivayisi we-elekthronikhi.
I-router broadband isebenzisa indinganiso ye- Ethernet yokuxhumana okuhlangene. Ama-router yendabuko omdabu adinga izintambo ze-Ethernet ezigijima phakathi kwe-router, i-modem ye-broadband, kanye nekhompyutha ngayinye kunethiwekhi yasendlini. Ama-router omusha omusha wokuxhumana okuxhunyiwe afakwe uxhumo oluxhunyiwe kwi-modem ye-intanethi. Baxhuma namadivayisi ekhaya ngokungenazintambo besebenzisa ama- Wi-Fi amazinga.
Izinhlobo eziningi zokuhamba zikhona, futhi ngayinye ihlangabezana nesilinganiso esithile. Ama-routers asebenzisa izinga eliphezulu lamanje ayatholakala ngezindleko eziphakeme kunalabo asezindinganisweni ezindala, kodwa zifaka izici ezingcono. Isilinganiso samanje ngu-802.11ac. Landulelwe ngu-802.11n futhi-ngisho nangaphambilini-802.11g. Zonke lezi zindinganiso zisekhona kuma-routers, nakuba asebekhulile abanemikhawulo.
802.11ac Routers
I-802.11ac iyinhlangano evamile kakhulu ye-Wi-Fi. Wonke ama-router angu-802.11ac ane-hardware entsha nesofthiwe kunezingxenye ezidlule futhi aphelele kumakhaya aphakathi namakhulu lapho isivinini nokuthembeka kubalulekile.
Umzila we-802.11ac usebenzisa ubuchwepheshe obungenazintambo obungenazintambo ezimbili futhi usebenza ku-5 GHz band, okuvumela ukufika kwe-1 Gb / s, noma ukukhishwa okukodwa okungu-500 Mb / s ku-2.4 GHz. Lejubane ilungele ukugembula, ukusakazwa kwe-HD yemidiya, nezinye izimfuneko zomkhawulokudonsa .
Lo mgangatho wamukele ubuchwepheshe ngo-802.11n kodwa wandisa amandla ngokuvumela i-RF bandwidth ububanzi njengo-160 MHz futhi uxhasa kuze kube nemifudlana eminingi yokufaka okuningi okukhipha okuningi (MIMO) kuze kufike kumaklayenti a-MIMO amaningi we-downlink.
Ubuchwepheshe be-802.11ac buya emuva buhambisana ne-802.11b, 802.11g, ne-802.11n hardware, okusho ukuthi ngenkathi umshini we-802.11ac isebenza ngamadivayisi we-hardware asekela izinga elingu-802.11ac, linikeza nokufinyelela kwenethiwekhi kumadivayisi asekela kuphela i-802.11b / g / n.
Ama-Routers angu-802.11n
IEEE 802.11n, evame ukubizwa ngokuthi ngu- 802.11n noma i-Wireless N), ithatha indawo yobuchwepheshe obudala obuyi-802.11a / b / g futhi yandisa amanani wedatha ngalezo zindinganiso ngokusebenzisa ama-multiple antenna, ukuzuza amazinga kusuka ku-54 Mb / s kufika ku-600 Mb / s , kuye ngokuthi inani lamarediyo kudivayisi.
Ama-router angu-802.11n asebenzisa imifudlana emine yendawo esiteshini se-40 MHz futhi angasetshenziswa kumabhanki ama-2.4 GHz noma ama-5 GHz.
Lawa ma routers abuyele emuva ahambisana nama-router angu-802.11g / b / a.
Ama-Routers angu-802.11g
Umgangatho we-802.11g ubuchwepheshe obudala be-Wi-Fi, ngakho-ke la ma router ngokuvamile ayabizi. I- 802.11g router ilungele amakhaya lapho isivinini esisheshayo singabalulekile.
I-router engu-802.11g isebenza ebangeni le-2.4 GHz futhi isekela isilinganiso esiphezulu se-54 Mb / s, kodwa ngokuvamile sinokungena kokuphakama kwesilinganiso se-22 Mb / s. Lezi zivinini zihle kakhulu ukuphequlula okuyisisekelo kwe-inthanethi kanye nokusakaza kwe-standard definition yemidiya.
Le nqubo ihambisana ngokugcwele ne-hardware esekudala ye- 802.11b , kodwa ngenxa yalesi sesekelo sefa, i-throughput incishiswe ngamaphesenti angaba ngu-20 uma kuqhathaniswa no- 802.11a .
