Problem in sharing ip of same lan

Hello,
i have a broadband cabel net in my home and i want to connect my villege which is 3 km far from my home. and it's in the mountain region. can i connect my villege from same broadband net? i am thinking to connect by using wireless antinnas like backhaul canopy, parabolic grid antenna? i don't know, can i use that broadband cabel net for wireless networking or i need the wireless net for my home? even i don't know what is the longest distance of above wireless antennas? and how to share ip between two wireless antennas
