Daboolida calaamadda taleefanka gacanta ee tunnel-kaSharaxaadda mashruuca:Nidaamka caymiska calaamadaha moobaylka ee Tianjin Electric Power Tunnel, qiyaastii 2 kiiloomitir dherer ahaan, oo leh 3 ul oo ku yaal godka,
Waxaa lagama maarmaan ah in lagu daboolo aagga shaqada ee tunnel-ka iyo meesha ay ku taal wadada kor u qaadida iyadoo la adeegsanayo calaamad saddex-shabakadood ah. Ka dib marka rakibidda la dhammeeyo, wicitaanka caadiga ah iyo shaqooyinka marin u helidda internetka ayaa lagu gaari karaa tunnel-ka.
Naqshad:
1. Marka hore, godka dhexdiisa, hal ilaa laba fiber optic repeater oo ku dhow dhammaadka + fiber optic repeater ayaa loo isticmaalaa in lagu daboolo godka. Dhan kasta oo fog waxaa ku xiran laba anteeno oo saxan ah, kuwaas oo dabooli kara masaafo qiyaastii 900 mitir ah. Sidaa darteed, 2 qaybood oo fog ah ayaa dabooli kara masaafo dhan 1800 mitir. Maadaama dabada ay leedahay xagal qayb ahaan qaloocan, repeater wireless ah oo 2W ah ayaa lagu daraa dabada si loo daboolo qaybta godka qaloocan ee dabada.
2. Daboolida aagga shaqada: Aagga gudaha usha waa yar yahay, saddex ku celceliye oo awood 2W ah ayaa loo isticmaali karaa in lagu xoojiyo calaamadda gudaha ee usha kasta.
