FAQ

Q1. He aha nā pōmaikaʻi nui o ka kamaʻilio laser ma mua o RF kuʻuna?
A.ʻOi aku ka nui o ka bandwidth (mau haneli Mbps a hiki i ka multi-Gbps), ʻoi aku ka maikaʻi o ka pale ʻana i ka hoʻopili electromagnetic, hoʻomaikaʻi i ka palekana loulou, a hoʻemi ʻia ka nui/mana no kahi waihona loulou like.

Q2. ʻO wai nā mikiona i kūpono no kēia mau pahu?
A.

Nā loulou waena ma waena o nā hōkū hōkū nui
Nā loulou kiʻekiʻe kiʻekiʻe satellite-a-lalo
Ka ʻimi ʻana i ka lewa hohonu (e laʻa, nā mikiona lunar a i ʻole Martian)
