1, ʻo ka mua ka tunnel, e hoʻohana ana i ka proximal yituo ʻelua optical fiber repeater station + distal fiber optic repeater station e uhi i ka tunnel, kēlā me kēia mamao e hoʻopili i ʻelua planarantenna, e uhi ana i ka mamao ma kahi o 900 mika, no laila, ʻo ka lōʻihi uhi ʻelua o 1800 mika. No ka mea ʻo ka ʻāpana huelo o ka Angle bending, ma ka hope e hoʻohui i kahi 2 w mana uʻi uila uʻi, hoʻohana ʻia e uhi i ka ʻāpana tunnel curved huelo.
2, uhi ʻia nā wahi: ʻaʻole nui ka maikaʻi i loko o ka wahi, hiki ke hoʻohana ʻia 3 w power repeater station 2 no kēlā me kēia kumu i loko o ka hōʻailona hōʻailona hoʻonui i ke kelepona kelepona.uhi hōʻailona.
