Hey mate. I do this for a living (not the satellite stuff cause it only works for about 4 months anyway hahaha). The only thing is its going to cost ya. no ways around it. If you can run cables through your walls your fine. We have setup Mobile antennas 22kms away from where you get signal without an antenna in mountainous country. My recommendation - Buy a 16dbi yagi -
http://www.ebay.com.au/itm/111037805...84.m1497.l2649 - they work fine believe it or not. Then buy a telstra Easy touch phone (And the patch lead to suit I can get the part number for that too later on when im not to busy). Plug it all in climb on your roof and start pointing it in every direction - go to settings About phone then i think its Status. It will show you coverage or Signal strength. You will want atleast -95db for mobile internet. With -95db you should experience roughly 1200kbps download and around 80kpbs upload. Any better signal and it will only get better. If i wasnt 2000kms away i would come do it for you with my test gear but sorry.
Once you have a good strong internet connection mount your antenna and run the cable in and then you can Mobile hotspot the phone as a modem. The reason we do it this way we have found the Telstra easy touch to be a lot more sensitive to signal than the modems are so its just easier. And you get a phone to take away with you.
People are being sucked into the NBN Satellite broadband but if you read the disclaimer its not being activated until 2015. So dont believe the hype, i come from a rural area and we replace new satellite systems daily with mobile internet.
