You can but you need to verify that with your local carriers first. I lived at the top of a hill in our last house but a house just up the road had a full sized 30f antenna for the web which took the juice out of every other house in that immediate area, us included. You can sometimes get away with a simple antenna (which costs around 1,200) to get but that might not enough. Depending on the area you are in some companies wont even come install anything because there is nothing set or your area so unless you have $30,000-50,000 to spend to get everything set up from the town to your house, you are out of luck (again a problem we ran into).
One of the main reasons we moved to our new house is because of the bad wireless connection we had.
