| When 've had this kind off situation what i have done is used wireless bridges and narrow angle antennas. You get the broadce installed in another building to which you have line of sight. Then hook the wireless bridge to the broad band router.
I can rent you the bridges and antennas to get access your home for up to 1km from your home. Also ideal when you need move into a new office and
You still need to find a neighbour who is going to let you install the broadce line and hang an antenna near a window. |
