Ngokusekelwe eminyakeni yocwaningo nesipiliyoni sokuthuthuka kumishini ye-inthanethi, sixoxe ngobuchwepheshe nezixazululo zokuqinisekisa ikhwalithi yenethiwekhi yasendlini ebanzi. Okokuqala, ihlaziya isimo samanje sekhwalithi yenethiwekhi yasendlini ye-broadband, futhi ifingqa izici ezihlukahlukene ezifana ne-fiber optics, amasango, amarutha, i-Wi-Fi, kanye nokusebenza komsebenzisi okubangela izinkinga zekhwalithi yenethiwekhi yasendlini ye-broadband yangaphakathi. Okwesibili, kuzokwethulwa ubuchwepheshe obusha bokuhlanganisa inethiwekhi yasendlini emakwe yi-Wi-Fi 6 kanye ne-FTTR (Fiber To The Room).
1. Ukuhlaziywa kwezinkinga zekhwalithi yenethiwekhi yangaphakathi ye-broadband yasekhaya
Ngohlelo lweI-FTTH(i-fiber-to-home), ngenxa yethonya lebanga lokudlulisa amehlo, ukuhlukaniswa kwe-optical kanye nokulahlekelwa kwedivayisi yokuxhumeka, kanye nokugoba kwe-fiber optical, amandla okubona atholwe isango angase abe phansi futhi izinga lephutha elincane lingase libe phezulu, okuholela ukwanda kwezinga lokulahlekelwa kwephakethe lokudluliswa kwesevisi yongqimba olungaphezulu. , izinga liyehla.
Kodwa-ke, ukusebenza kwezingxenyekazi zekhompiyutha zamasango amadala ngokuvamile kuphansi, futhi izinkinga ezifana ne-CPU ephezulu nokusetshenziswa kwenkumbulo nokushisisa ngokweqile kwezinto zokusebenza kuthambekele ekuqaliseni kabusha okungavamile kanye nokuphahlazeka kweminyango. Amasango amadala ngokuvamile awasekeli isivinini senethiwekhi ye-gigabit, futhi amanye amasango amadala nawo anezinkinga ezifana nama-chips aphelelwe yisikhathi, okuholela esikhaleni esikhulu phakathi kwenani langempela lesivinini soxhumo lwenethiwekhi kanye nenani lethiyori, eliphinde libeke imingcele ithuba lokuthuthukisa ulwazi oluku-inthanethi lomsebenzisi. Njengamanje, amasango amadala asekhaya ahlakaniphile asesetshenziswe iminyaka emi-3 noma ngaphezulu kunethiwekhi ebukhoma asathatha ingxenye ethile futhi adinga ukushintshwa.
Ibhendi yefrikhwensi engu-2.4GHz yibhendi yefrikhwensi ye-ISM (Industrial-Scientific-Medical). Isetshenziswa njengebhendi yefrikhwensi evamile yeziteshi zomsakazo ezifana nenethiwekhi yendawo engenantambo, isistimu yokufinyelela okungenantambo, isistimu ye-Bluetooth, i-point-to-point noma i-point-to-multipoint spread spectrum communication system, enezinsiza ezimbalwa zefrikhwensi kanye nomkhawulokudonsa olinganiselwe. Okwamanje, kusenengxenye ethile yamasango asekela ibhendi yefrikhwensi ye-2.4GHz Wi-Fi kunethiwekhi ekhona, futhi inkinga yokuphazanyiswa kwe-co-frequency/edacent frequency igqame kakhulu.
Ngenxa yeziphazamisi zesofthiwe nokusebenza okunganele kwezingxenyekazi zekhompiyutha kwamanye amasango, ukuxhumeka kwe-PPPoE kuvame ukwehliswa futhi amasango avame ukuqaliswa kabusha, okuholela ekuphazamisekeni okuvamile kokufinyelela ku-inthanethi kubasebenzisi. Ngemva kokuthi uxhumo lwe-PPPoE luphazanyiswe kancane (isibonelo, isixhumanisi sokudlulisa i-uplink siphazamisekile), umkhiqizi wesango ngalinye unamazinga okusebenzisa angahambisani okutholwa kwembobo ye-WAN nokwenza kabusha ukudayela kwe-PPPoE. Amasango abakhiqizi abathile athola kanye njalo kumasekhondi angu-20, futhi aphinde adale kabusha kuphela ngemva kokutholwa okuhlulekile okungu-30. Ngenxa yalokho, kuthatha imizuzu eyi-10 ukuthi isango liqalise ngokuzenzakalelayo ukudlala kabusha kwe-PPPoE ngemva kokuphuma ungaxhumekile ku-inthanethi ungenzi lutho, okuthinta kabi ulwazi lomsebenzisi.
Amasango asekhaya abasebenzisi abengeziwe alungiswa ngamarutha (ngemuva kwalokhu azobizwa “njengamarutha”). Kula marutha, ambalwa asekela kuphela izimbobo ezingu-100M WAN, noma (futhi) asekela kuphela i-Wi-Fi 4 (802.11b/g/n).
Amanye amarutha abakhiqizi asesenechweba elilodwa kuphela le-WAN noma iphrothokholi ye-Wi-Fi esekela isivinini senethiwekhi ye-Gigabit, futhi abe amarutha “angelona iqiniso e-Gigabit”. Ngaphezu kwalokho, i-router ixhunywe esangweni ngentambo yenethiwekhi, futhi ikhebula lenethiwekhi elisetshenziswa abasebenzisi ngokuyisisekelo liyikhebula lesigaba 5 noma i-super category 5, elinempilo emfushane nekhono elibuthakathaka lokulwa nokuphazamiseka, futhi iningi lazo kuphela. ukusekela 100M isivinini. Awekho amarutha ashiwo ngenhla nezintambo zenethiwekhi ezingahlangabezana nezidingo zokuvela kwamanethiwekhi alandelayo e-gigabit kanye ne-super-gigabit. Amanye amarutha aqala kabusha njalo ngenxa yezinkinga zekhwalithi yomkhiqizo, okuthinta kabi ulwazi lomsebenzisi.
I-Wi-Fi iyindlela eyinhloko yokumboza okungenantambo yasendlini, kodwa amasango amaningi asekhaya abekwe emabhokisini amanje abuthakathaka emnyango wabasebenzisi. Kukhawulelwe indawo yebhokisi lamanje elibuthakathaka, okokusebenza kwekhava, nohlobo lwendlu oluyinkimbinkimbi, isignali ye-Wi-Fi ayanele ukumboza zonke izindawo zasendlini. Uma idivayisi yetheminali isuka kude nendawo yokufinyelela ye-Wi-Fi, kuba nezithiyo ezengeziwe, nokulahlekelwa okukhulu kwamandla esignali, okungase kuholele ekuxhumekeni okungazinzile nokulahlekelwa kwephakethe ledatha.
Endabeni yokuxhumana kwangaphakathi kwamadivayisi e-Wi-Fi amaningi, izinkinga zokuphazanyiswa kwemvamisa efanayo neziteshi eziseduze zivame ukwenzeka ngenxa yezilungiselelo zesiteshi ezingenangqondo, okuqhubeka kwehlisa izinga le-Wi-Fi.
Lapho abanye abasebenzisi bexhuma irutha esangweni, ngenxa yokuntuleka kokuhlangenwe nakho kochwepheshe, bangase baxhume umzila embobeni yenethiwekhi engeyona ye-gigabit yesango, noma bangase bangayixhumi ngokuqinile ikhebula lenethiwekhi, okuholela ezimbobeni zenethiwekhi ezixegayo. Kulezi zimo, ngisho noma umsebenzisi ebhalisela isevisi ye-gigabit noma esebenzisa i-router ye-gigabit, akakwazi ukuthola izinsizakalo ezizinzile ze-gigabit, ezibuye zilethe izinselele ku-opharetha ukubhekana namaphutha.
Abanye abasebenzisi banamadivayisi amaningi kakhulu axhunywe ku-Wi-Fi ezindlini zabo (ngaphezu kuka-20) noma izinhlelo zokusebenza eziningi zilanda amafayela ngesivinini esikhulu ngesikhathi esisodwa, okuzophinda kubangele ukungqubuzana okukhulu kwesiteshi se-Wi-Fi nokuxhumeka kwe-Wi-Fi okungazinzile.
Abanye abasebenzisi basebenzisa amatheminali amadala asekela kuphela ibhendi yefrikhwensi ye-Wi-Fi 2.4GHz noma amaphrothokholi amadala we-Wi-Fi, ngakho-ke ngeke bakwazi ukuthola ulwazi lwe-inthanethi oluzinzile futhi olusheshayo.
2. Ubuchwepheshe obusha bokuthuthukisa inethiwekhi yasendliniQukuphila
I-high-bandwidth, izinsiza zokulinda kancane ezifana nevidiyo ye-4K/8K ephezulu-definition, i-AR/VR, imfundo ye-inthanethi, nehhovisi lasekhaya kancane kancane ziba izidingo eziqinile zabasebenzisi basekhaya.

Kodwa-ke, ubuchwepheshe be-Wi-Fi 6 kanye ne-FTTR bungahlangabezana kangcono nezimfuneko zesevisi ezingenhla futhi kufanele zisetshenziswe ngezinga elikhulu ngokushesha ngangokunokwenzeka.
I-Wi-Fi 6
Ngo-2019, i-Wi-Fi Alliance yaqamba ubuchwepheshe be-802.11ax Wi-Fi 6, futhi yaqamba ubuchwepheshe bangaphambilini be-802.11ax no-802.11n i-Wi-Fi 5 ne-Wi-Fi 4 ngokulandelanayo.
I-Wi-Fi 6yethula i-OFDMA (i-Orthogonal Frequency Division Multiple Access, i-Orthogonal Frequency Division Multiple Access), i-MU-MIMO (I-Multi-User-Multiple-Input Multiple-Output, ubuchwepheshe bokuphuma okuningi kwabasebenzisi bokufaka okuningi), 1024QAM (Quadrature Amplitude Moduture, i-quadrature ukumodulation) nobunye ubuchwepheshe obusha, izinga lokulanda eliphezulu lethiyori lingafinyelela ku-9.6Gbit/s. Uma iqhathaniswa nobuchwepheshe obusetshenziswa kakhulu be-Wi-Fi 4 kanye ne-Wi-Fi 5 embonini, inezinga eliphezulu lokudlulisela, amandla amakhulu okusebenzisa imali, ukubambezeleka okuphansi kwesevisi, ukumbozwa okubanzi namandla amancane okugcina. ukusetshenziswa.
I-FTTRTubuchwepheshe
I-FTTR isho ukuthunyelwa kwamasango abona konke kanye namadivayisi amancane ezindlini ngesisekelo se-FTTH, kanye nokufezekiswa kokuxhumana kwe-optical fiber emakamelweni abasebenzisi ngokusebenzisa.I-PONubuchwepheshe.
Isango elikhulu le-FTTR liwumgogodla wenethiwekhi ye-FTTR. Ixhunywe phezulu ku-OLT ukuze inikeze i-fiber-to-the-home, naphansi ukuze inikeze izimbobo zokubona ukuze kuxhunywe amasango ezigqila e-FTTR amaningi. Isango lezigqila le-FTTR lixhumana nemishini yetheminali ngokusebenzisa ukuxhumana kwe-Wi-Fi ne-Ethernet, lihlinzeka ngomsebenzi wokuhlanganisa ukuze lidlulisele idatha yesisetshenziswa setheminali esangweni elikhulu, futhi lamukela ukuphathwa nokulawulwa kwesango elikhulu le-FTTR. Inethiwekhi ye-FTTR iboniswa esithombeni.
Uma kuqhathaniswa nezindlela zendabuko ezifana nenethiwekhi yamakhebula enethiwekhi, ulayini wamandla kagesi, nenethiwekhi engenantambo, amanethiwekhi e-FTTR anezinzuzo ezilandelayo.
Okokuqala, imishini yokuxhumana inokusebenza okungcono kanye nomkhawulokudonsa ophezulu.
