Kev them nqi xov tooj ntawm tes rau lub qhov avKev piav qhia txog qhov project:mobile Signal coverage system ntawm Tianjin Electric Power Tunnel, ntev li ntawm 2 kilometers, nrog 3 lub qhov av hauv qhov av,
Nws yog ib qho tsim nyog los npog thaj chaw ua haujlwm ntawm lub qhov av thiab txoj kev nqa khoom nrog peb lub teeb liab network. Tom qab kev teeb tsa tiav lawm, kev hu xov tooj + kev nkag mus rau hauv Is Taws Nem tuaj yeem ua tiav hauv lub qhov av.
Tsim:
1. Ua ntej tshaj plaws, hauv qhov av, ib qho fiber optic ze-kawg repeater + fiber optic chaw taws teeb repeater siv los npog qhov av. Txhua qhov kawg txuas nrog ob lub phaj antennas, uas tuaj yeem npog qhov deb li ntawm 900 meters. Yog li ntawd, 2 pawg ntawm chaw taws teeb tuaj yeem npog qhov deb ntawm 1800 meters. Vim tias tus Tsov tus tw muaj lub kaum sab xis ib nrab, 2W fais fab wireless repeater ntxiv rau ntawm tus Tsov tus tw kom npog qhov seem nkhaus ntawm tus Tsov tus tw.
2. Kev npog thaj chaw ua haujlwm: Thaj chaw sab hauv lub ncej me me, thiab peb lub zog rov ua dua 2W tuaj yeem siv los txhim kho lub teeb liab sab hauv tsev ntawm txhua lub ncej.
