Kufalikira kwa ma foni am'manja panjiraKufotokozera kwa polojekiti:Mobile Signal coverage system ya Tianjin Electric Power Tunnel, pafupifupi makilomita 2 m'litali, ndi mitsinje 3 mumsewu,
M'pofunika kuphimba ngalande ndi hoistway ntchito malo ndi atatu maukonde chizindikiro Kuphunzira.Kuyikako kukamalizidwa, kuyimba kwanthawi zonse + pa intaneti kumatha kuchitika mumsewu.
Kupanga:
1. Choyamba, mumsewu, imodzi-to-2 fiber optic pafupi-end repeater + fiber optic remote repeater imagwiritsidwa ntchito kuphimba ngalandeyo.Kumapeto kulikonse kumalumikizidwa ndi tinyanga tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ta 900.Chifukwa chake, ma seti a 2 akutali amatha kuphimba mtunda wa 1800 metres.Chifukwa mchira uli ndi ngodya yopindika pang'ono, chobwereza chamagetsi cha 2W chamagetsi chimawonjezedwa kumchira kuphimba gawo lopindika pamchira.
2. Kuphimba malo ogwira ntchito: Malo omwe ali mkati mwa shaft ndi ochepa, ndipo atatu obwereza mphamvu a 2W angagwiritsidwe ntchito kupititsa patsogolo chizindikiro chamkati cha shaft iliyonse.
