Video ea lipapali le livideo e rua molemo ho tloha li-routers tsa mahae
Li-router tse kholo li etselitsoe hore li be bonolo ho theha marang-rang a lehae, haholo-holo bakeng sa matlo a nang le tšebeletso ea inthanete e potlakileng . Ntle le ho etsa hore lisebelisoa tsohle tsa elektronike tsa malapeng li arolelane khokahanyo ea inthanete, li-routers tse sephara li boetse li nolofalletsa ho arolelana lifaele, likhatiso le lisebelisoa tse ling har'a lik'homphieutha tsa lapeng le lisebelisoa tse ling tsa elektronike.
Routerband e kholo e sebelisa mokhoa oa Ethernet bakeng sa maqhama a wired. Li-router tsa mekhoa e mecha ea marang-rang li hloka lisebelisoa tsa Ethernet tse tsamaeang pakeng tsa router, modem e kholo, le khomphuteng e 'ngoe le e' ngoe ea marang-rang. Li-routers tse ncha tse ncha li na le khokahanyo ea motlakase ho modem ea inthanete. Li kopanya le lisebelisoa tsa lehae ka mohala ka mokhoa oa Wi-Fi .
Mefuta e fapaneng ea li-routers e fumaneha, 'me e' ngoe le e 'ngoe e finyella maemo a itseng. Li-routers tse sebelisang tekanyo ea morao-rao li fumaneha ka lits'enyehelo tse phahameng ho feta tsa litekanyetso tsa khale, empa li kenyelletsa lintlha tse molemo. Mokhoa oa hona joale ke 802.11ac. E ne e etelletsoe pele ke 802.11n le-esita le pejana-802.11g. Melao ena kaofela e ntse e fumaneha ka li-routers, le hoja ba baholo ba na le meeli.
Basebelisi ba 802.11ac
802.11ac ke tekanyo e ncha ka ho fetisisa ea Wi-Fi. Li- router tsohle tsa 802.11ac li na le li-hardware tse ncha le software ho feta mekhoa ea nakong e fetileng ebile li phethahetse bakeng sa mahareng a maholo ho ea maholo moo ho potlakileng le ho tšepahala ho bohlokoa.
Router ea 802.11ac e sebelisa theknoloji ea li-wireless-band e sebetsang 'me e sebetsana le sehlopha sa 5 GHz, se lumellang ho kena ho 1 Gb / s, kapa se-single link linking 500 Mb / s ka 2.4 GHz. Lebelo lena le loketse ho bapala, ho phatlalatsoa ha mecha ea litaba ea HD, le litlhoko tse ling tse matla tsa bandwidth .
Tekanyetso ena e amohetse theknoloji ka 802.11n empa e atolose bokhoni ka ho lumella RF bandwidth e le bophara ba 160 MHz le ho tšehetsa melaetsa e mengata e mengata e kenang e mengata (MIMO) le ho fihlela ho bareki ba MIMO ba bangata ba downlink.
Theknoloji ea 802.11ac e tsamaisana le 802.11b, 802.11g, le 802.11n, e bolelang hore le hoja router 802.11ac e sebetsa le lisebelisoa tsa thepa e tšehetsang tekanyo ea 802.11ac, e boetse e fana ka phihlelo ea lisebelisoa tsa lisebelisoa tse fanang ka tšehetso ea 802.11b / g / n.
802.11n Routers
IEEE 802.11n, eo hangata e bitsoang 802.11n kapa Wireless N), e nka mekhoa ea khale ea 802.11a / b / g le ho eketsa litekanyetso tsa data ho feta litekanyetso tseo ka ho sebelisa li-antenna tse ngata, ho finyella litekanyetso ho tloha ho 54 Mb / s ho fihlela ho 600 Mb / s , ho itšetlehile ka palo ea li-radios ka sesebelisoa.
Li-router tse 802.11n li sebelisa melapo e mene ea libaka molareng oa 40 MHz 'me li ka sebelisoa mofuteng oa maqhubu a 2.4 GHz kapa a 5 GHz.
Li-routers tsena li khutlela morao li lumellana le li-routers tse 802.11g / b / a.
802.11g Routers
Tekanyetso ea 802.11g ke theknoloji ea khale ea Wi-Fi, kahoo li-router tsena hangata li theko e tlaase. Koloi ea 802.11g e loketse mahae ao maoto a potlakileng ka ho fetisisa a sa bohloeng.
Koloi ea 802.11g e sebetsana le sehlopha sa 2.4 GHz mme e tšehetsa boholo ba 54 Mb / s, empa hangata e na le hoo e ka bang ka 22 Mb / s ea phallo. Tsena li potlakile bakeng sa ho bapala websaeteng ea motheo le melaetsa e tloaelehileng ea mecha ea phatlalatso.
Tekanyetso ena e lumellana ka botlalo le thepa ea khale ea 802.11b , empa ka lebaka la tšehetso ena ea lefa, phallo e fokotseha ka liphesente tse 20 ha e bapisoa le 802.11a .
