Building Wireless metropolitan area network

Hello Guys,

I'm planning to build wireless metropolitan area network with 4-7 km coverage. This project intended to bring internet to our home from the base station where we can get internet but that base station is 3-4 km away from our house.

Can anyone recommend Access point and outdoor antenna.

Thanks
Alex
