Inkcazo yeprojekthi: 2 km amandla asebenza kwi-tunnel kunye ne-shaft mobile phoneisiphindaphindi sesiginaliisisombululo. KwiTianjin, eTshayina, inkqubo yokugubungela imisele yamandla ombane, ubude bayo bumalunga ne-2 km, imisele ene-shaft ezi-3,
Kufuneka umhubhe kunye necandelo le-shaft umhubhe wesithathuisixhasi sesiginali se-netcomIsigqubuthelo, esifakwe emva kokugqitywa komngxuma, sinokufikelela kwifowuni eqhelekileyo + ukufikelela kwi-intanethi ngaphakathi komngxuma.
Uyilo lwesisombululo sesignali yeselfowuni
1, eyokuqala yi-tunnel, eyamkela i-proximal yituo two optical fiber repeater station + i-distal fiber optic repeater station ukuze igubungele i-tunnel, nganye idibanisa i-planar ezimbini kude.i-antenna, Umgama wokugubungela umalunga neemitha ezingama-900, ngoko ke umgama wokugubungela umgama ophakathi kweemitha ezili-1800. Ngenxa yokuba inxalenye yomsila we-engile igobile, ekugqibeleni yongeza izitishi zokuphindaphinda ezingenazingcingo ze-2 w, ezisetyenziselwa ukugubungela icandelo le-tunnel eligobileyo lomsila.
2, iindawo ezigutyungelweyo: ngaphakathi kwendawo azikhulu, zingasetyenziswa isikhululo sokuphinda amandla se-3w 2 kwitshaneli nganye yokwandisa isignali yangaphakathi ifowuni ephathwayoukugquma isignali.
Umzobo woqhagamshelo
Uluhlu lwezixhobo
Ukuba ufuna ukunxibelelana nabanyeisandisi-lizwi sefowuni, nxibelelana nenkonzo yethu yabathengi, siza kukunika isicwangciso esibanzi sokugubungela isignali.
