Hoʻopaʻa hōʻailona kelepona paʻalima no ka tunnelwehewehe papahana:ʻōnaehana hoʻopili hōʻailona kelepona o Tianjin Electric Power Tunnel, ma kahi o 2 mau kilomita ka lōʻihi, me 3 mau ʻau i loko o ka tunnel,
Pono e uhi i ka tunnel a me ka wahi hana hoistway me ka uhi hōʻailona ʻekolu.Ma hope o ka pau ʻana o ka hoʻonohonoho ʻana, hiki ke hoʻokō ʻia nā hana kelepona maʻamau + Internet i ka tunnel.
Hoʻolālā:
1. ʻO ka mea mua, ma ka tunnel, hoʻohana ʻia kahi mea hoʻohana hoʻokahi a i ʻelua fiber optic kokoke i ka hopena hou + fiber optic remote repeater e uhi i ka tunnel.Hoʻopili ʻia kēlā me kēia ʻaoʻao mamao i ʻelua antenna pā, hiki ke uhi i kahi mamao ma kahi o 900 mika.No laila, hiki i nā pūʻulu mamao 2 ke uhi i kahi mamao o 1800 mika.No ka mea, he ʻāpana ʻāwili ʻana o ka huelo, ua hoʻohui ʻia kahi mea uila uila mana 2W ma ka huelo e uhi i ka ʻāpana tunnel curved ma ka huelo.
2. Ka uhi o ka wahi hana: He liʻiliʻi ka wahi i loko o ka lāʻau, a hiki ke hoʻohana ʻia ʻekolu mau mana 2W e hoʻonui i ka hōʻailona o loko o kēlā me kēia kumu.
