1, Phambi kokwazisa iFTTR, masiqonde ngokufutshane ukuba yintoni iFTTx.
I-FTTx sisishunqulelo se-"Fayibha ukuya ku-x", ibhekisa ku-"ifayibha ukuya ku-x", apho u-x engameli kuphela indawo apho ifayibha ifika khona, kodwa ikwabandakanya izixhobo zothungelwano olubonayo olufakwe kuloo ndawo, kwaye ikhankanya indawo esetyenziswa izixhobo zenethiwekhi. Umzekelo,
Isishunqulelo esithi "B" kwi-FTTB siSakhiwo, esibhekisa kwintambo yefiber optic ukusuka kwisakhiwo ukuya kwesinye, intambo yangaphakathi yefiber optic efakwe kwipaseji, yaze yaqhagamshelwa kubasebenzisi ngentambo ejijekileyo. Indawo esetyenziswa yikati yamehlo sisakhiwo esinye okanye abasebenzisi bomgangatho omnye.
U-"H" kwi-FTTH sisishunqulelo se-"Home", esibhekiselele kwintambo yefiber optic esuka ekhaya, intambo yefiber optic yangaphakathi ibekwe kwikhaya lomsebenzisi, kwaye ikati yamehlo ifakwe kwikhaya lomsebenzisi. Indawo esetyenziswa yikati yamehlo likhaya elinye.
Isishunqulelo esithi "R" kwi-FTTR sibhekisa kunxibelelwano lwefiber optic kumagumbi amabini okanye ngaphezulu kwikhaya lomsebenzisi, kunye nokufakwa kweekati zokukhanya kumagumbi ahambelanayo. Ikati nganye ye-optical inceda igumbi elinye ukuya kwangaphezulu ekhaya.
2, Ke kutheni sifuna i-FTTR? Masiqale siqonde iimfuno ze-WiFi zomsebenzisi wangoku, eziqhuba isicelo.
Okwangoku, uninzi lwabasebenzisi bendlu yangaphakathi ye-WiFi ifikelelekaI-ONU/ONT, enikezelwe yiWiFi yabo okanye iqhagamshelwe kwiWiFiumzila, igutyungelwe ngumqondiso we-WiFi we-router. Kukho iintlobo ezimbini eziqhelekileyo zezixhobo ze-WiFi kwimarike: i-frequency eyodwa kunye ne-dual frequency. I-frequency eyodwa isekela kuphela i-2.4G ye-frequency band, kwaye nangona inokuxhasa izinga eliphezulu le-300Mbps, umphumo wangempela wokusetyenziswa ubi kakhulu ngenxa yokuphazamiseka okuphezulu kweli qela le-frequency. Iifrikhwensi ezimbini, ezixhasa zombini i-2.4G kunye ne-5G iibhendi zamaza. I-5G i-WiFi iphuculwe ngesantya, kodwa ukukwazi kweempawu ze-5G ze-WiFi ukudlula kwiindonga zibuthathaka, okuzisa ukuphazamiseka okukhulu kwamanye amakhaya amakhulu kunye nabasebenzisi abaninzi.
Okwangoku, kukho iintlobo ezintathu eziphambili zeenkqubo zokugubungela iWiFi kwimarike: iumzilaiskimu se-cascade kukuseta inkosiumzilakwikati yamehlo, kwaye igumbi ngalinye lixhotyiswe ngekhobokaumzila. Ii-master kunye neerotha zekhoboka ziqhagamshelwe kusetyenziswa iintambo zoDidi 6. Ngenxa yokuthintelwa kwenani lamazibuko e-LAN kwindawo engundoqoumzila, inani lee-router zesibini ngokubanzi alidluli kwi-4. Ukuba oku kudlula umda, utshintsho olongezelelweyo kufuneka longezwe kwindawo ephambili.umzila. Ngenxa yokusetyenziswa koxhumo lweengcingo, esi sikimu sinokuqinisekisa uxhulumaniso lwegigabit phakathi kwenkosi kunye neendlela zekhoboka; Ukungalungi kukuba iintambo zeCandelo 6 kufuneka zibekwe ngaphakathi kwindlu, enobunzima obuthile bokuphunyezwa kwaye inokuchaphazela i-aesthetics. Ukongeza, kunzima ngokuzenzekelayotshintshai-WiFi SSID yesixhobo ngasinye.
Iikati zamandla zahlulwe zaba ziikati zamandla ezinentambo kunye neekati zamandla ezingenazingcingo. Qhagamshela ikati yamandla enentambo kwizibuko le-LAN yeumzilausebenzisa intambo yeCandelo 6; Ikati yamandla engenazingcingo yi-wirelessumzilaenokuthi ifakwe kuyo nayiphi na indawo yombane endlwini (ngokukhethekileyo indawo yokuphuma eludongeni), kunye nekati yombane enentambo inokudityaniswa neekati ezininzi zamandla ezingenazingcingo ukuze zisetyenziswe. Umqondiso phakathi kweekati zombane ezineentambo kunye neekati zamandla ezingenazingcingo zisasazwa ngeentambo zombane, kwaye isantya sothungelwano sichatshazelwa kakhulu ngumgangatho wentambo yombane yangaphakathi kubasebenzisi. Ngaphezu koko, iitheminali zihlala zithande ukuqhawuka xa uzulazula kwii-AP ezahlukeneyo.
Iskimu somntwana sisiya emntwaneni sibandakanya umzali omnyeumzilakunye neerotha ezininzi zabantwana, kwaye nganyeumzilainokufakwa kwi-WiFi. Ngenxa yobunzima bokungadluli kwiindonga zeempawu ze-WiFi phakathi kwee-routers, i-bandwidth ye-bandwidth yesi sikimu ichaphazeleka kakhulu yimekobume. Kukho imveliso yembewu kunye nonina esebenzisa i-WiFi kunye neentambo zombane zokusasaza phakathi komntwana kunye noomama abajikelezayo ngaxeshanye, nto leyo eye yaphucula isakhono sokungena kodonga lwe-WiFi ukuya kumlinganiselo othile. Nangona kunjalo, umthamo we-bandwidth jikelele usabambekile kakhulu xa uthelekiswa neumzilaiskim se-cascade.
3. Izinto ezilungileyo zeFTTR
I-FTTR isebenzisa intambo enye ephambili yokukhanya kunye neentambo ezininzi zamakhoboka okukhanya angaphakathi kwi-WiFi yangaphakathi. Iintambo ze-optical eziphambili kunye nekhoboka zixhunyiwe ngebhabhathane okanye iintambo ezifihliweyo. Xa kuthelekiswa namacebo angasentla, i-FTTR ineenzuzo ezilandelayo: (1) i-butterfly okanye i-optical cables efihliweyo kulula ukubeka ngaphezu kweentambo ze-Class 6, kwaye ukufakwa kweentambo ezifihliweyo akuchaphazeli i-aesthetics yangaphakathi; (2) Isantya esiphezulu sothungelwano kufuphi nayiphi na ikati ye-optical kubasebenzisi be-gigabit inokufikelela kwi-1000Mbps; (3) Isantya sothungelwano oluzinzileyo, ukutshintshwa kwe-terminal ezinzileyo phakathi kweekati ze-optical; (4) Ubomi be-optical fibers budlula iminyaka engama-20, kwaye i-bandwidth iphantse ingapheli.
Ngenxa yolu ncedo lungasentla lweFTTR, uninzi lwabavelisi bezixhobo ngoku batyala imali kulo mmandla, njengale:
I-Huawei Home automation=FTTR+Hongmeng
I-FTTR yonke i-WiFi ye-optical, ngokudityaniswa okugqibeleleyo kwenkosi kunye neekati ze-optical khoboka, isebenzisa i-fiber optical endaweni ye-network cable ukugubungela i-gigabit broadband kwigumbi ngalinye losapho, elisisiseko soqhagamshelwano lwe-automation yaseKhaya. Inkqubo yokusebenza yaseHongmeng yinkqubo yokusebenza yetheminali ekrelekrele kwixesha le-Intanethi yeYonke into, enokusetyenziswa kwiiwotshi, iiselfowuni, iaudio, oomabonakude kunye nezinye izixhobo, kwaye inokudityaniswa ngokucofa, Yenza i-terminal ephezulu kwaye uqhagamshele. nabanye.
