Inkqubo ye-Lintratek's Fiber Optic Repeater ihambisa iSignali yeSelfowuni engenasiphako kwiiTunnels zamandla

Kwihlabathi elingaphantsi komhlaba elingaphantsi kwesixeko, iipaseji zombane zisebenza njenge "imithambo yombane," ukuqinisekisa umbane ozinzileyo ngelixa zigcina izixhobo zomhlaba ezixabisekileyo kwaye zigcina ubuhle bedolophu. I-lintratek kutshanje isebenzise ubuchule bayo obunzulu ekugubungeleni imiqondiso ukuze igqibezele ukusasazwa kwesignali yeselula ye-4.3 km kwiipaseji ezintathu zombane eYinchuan, eNingxia, iqinisa isiseko seziseko zophuhliso ezikrelekrele zesixeko.

Unxibelelwano olubalulekileyo loKhuseleko kwindawo yoMjelo

Ngaphakathi kwezi tunnels, akuphelelanga nje ekufakweni kweenkqubo zokubeka esweni umbane, kodwa kufakelwe nezinzwa zokulandelela abasebenzi kunye nomgangatho womoya—ukukhusela ubomi bomsebenzi ngamnye. Ukufikelela ekugutyungelweni kwesignali yeselula ngaphandle kokuphazamiseka kulo lonke tunnel ke ngoko yayiyeyona njongo iphambili yale projekthi.

Isisombululo soBugcisa: Ukugubungela ngokuchanekileyo kunye noThumelo oluZinzileyo

Isiphindaphindi seDijithali seFiber Optic

- Ubuchwepheshe obuphambili: i-lintratek ithumeleisiphindaphindi se-fiber optic yedijithaliXa kuthelekiswa nezinye iindlela ze-analog, ii-repeaters zedijithali zibonelela ngokucubungula isignali okuzinzileyo ngakumbi, ubomi bezixhobo obude, kunye neendleko zokulungisa eziphantsi—zonke zibalulekile kwiindawo ezinzima phantsi komhlaba.

- Ukusebenza okunamandla aphezulu: I-repeater nganye ye-digital fiber optic inika amandla aphezulu e-10 W kwaye ixhasa zonke iibhendi ezinkulu zefrikhwensi yenkampani, iqinisekisa amandla esignali yeselula aqinileyo.

I-Antenna yangaphakathiIcebo

- Amacandelo Athe Tye: Ii-antenna zepleyiti ezifumana inzuzo ephezuluzifakelwe ukuze kuphuculwe ukungena kwesignali yeselula.

- Iigophe ezigobileyo: Ii-antenna ze-log-periodiczikhethwe ukuze zilungelelanise ukusasazeka kwesignali macala onke.

- Iinxalenye zokuwela uMlambo: Ii-antenna ezivuzayo (iintambo) ziqinisekise ukuba zigqunywe rhoqo phantsi komjelo onqumla amanzi.

Ukoyisa Imingeni Yokwakha

Imeko-bume engaphantsi komhlaba yayineendawo ezinamanzi amileyo kunye nokufuma okuphezulu, nto leyo eyayifuna iindlela ezibalaseleyo zokuthintela ukungenwa kwamanzi kunye namanyathelo okulwa nokugqwala. Ii-repeater ze-fiber optic ze-lintratek ezikumgangatho wezoshishino zineendawo eziqinileyo, ezingenakushukunyiswa, kwaye ezingenakuphazanyiswa—ziqinisekisa ukusebenza okuzinzileyo nangona kufuma kunye nokungcangcazela.

- Uthungelwano oluSebenzayo:Ngokucokisa iindlela zothutho kunye neendlela zokusebenza kwindawo, iqela le-lintratek ligqibe zonke izinto ezifakelweyo kwiintsuku ezili-15 kuphela.
- Ukuqinisekiswa kokusebenza:Uvavanyo lwasemva kokusasazwa luqinisekisile ukuba iifowuni zelizwi bezicacile kwaye ukuhanjiswa kwedatha kudlule oko bekulindelwe, nto leyo eyahlangabezana ngokupheleleyo neemfuno zonxibelelwano zetonela.

Ubungcali obuPhambili kwiShishini le-lintratek

NgeIminyaka eli-13 yamava kwimveliso izikhuseli zesignali zeselfowunikunye nokuyilaiinkqubo ze-antenna ezisasazwe (i-DAS), i-lintratekIzinikele ekunikezeleni izisombululo zokugubungela isignali ezikumgangatho ophezulu kwiimeko ezahlukeneyo. Impumelelo yale projekthi ye-power-tunnel igxininisa ubunkokeli be-lintratek kwicandelo lokukhulisa isignali yeselula kunye namandla ayo ekusetyenzisweni kweenkqubo zokuphindaphinda i-fiber optic yedijithali kwizicelo ezibalulekileyo.
