Daboolka calaamada taleefanka gacanta ee tunnel-kaSharaxaada mashruuca:Nidaamka daboolida signalka mobilada ee Tianjin Power Tunnel, dhererkeedu wuxuu gaarayaa 2 kiiloomitir, oo leh 3 ulood oo tunnel ah,
Waa lagama maarmaan in lagu daboolo tunnel-ka iyo aagga hawlgallada marin-biyoodka oo leh dabool saddex-shabakad ah.Ka dib markii rakibidda la dhammeeyo, wacitaanka caadiga ah + hawlaha gelitaanka internetka ayaa lagu gaari karaa tunnel-ka.
Naqshad:
1. Marka hore, tunnel-ka, hal-ilaa-labo fiber optic-ga dhow-dhamaadka ku-celceliya + Fiber optic Remote repeater ayaa loo isticmaalaa in lagu daboolo tunnel-ka.Mid kasta oo fog waxa uu ku xidhan yahay laba anteeno saxan ah, kuwaas oo dabooli kara masaafo dhan ilaa 900 mitir.Sidaa darteed, 2 qaybood oo fog ayaa dabooli kara masaafo dhan 1800 mitir.Sababtoo ah badhidu waxay leedahay xagal qayb ahaan qaloocan, 2W ku celisiyaha bilaa-waayirka ah ayaa lagu daraa dabada si ay u daboosho qaybta tunnel-ka ee dabada.
2. Daboolida goobta shaqada: Meesha ku jirta usheeda dhexe waa yar tahay, saddex koronto oo 2W ah ayaa loo isticmaali karaa si kor loogu qaado calaamadda gudaha ee usheeda dhexe.
