Cellular phones transmit on radio frequencies. Signal strength can be diminished by a number of factors, including geographic conditions (trees, mountains, hills) or some of the construction materials that may have been used in your home (steel framework, concrete block, metal siding). You're not alone here, lots of people have the same problem. In my neighborhood, most of the people on the block keep their phones in a windowsill because we're surrounded by a lot of huge oak trees, above-ground powerlines, etc.
If you're willing to invest some money to improve your indoor reception, you can check into a signal booster/repeater like what I got. As long as you have a fair signal outside, you can bring that signal inside with a repeater. Check out the following links:

I got mine from the second link and it covers
most of my house, but if you have a lot of square footage to cover you should consider checking out Wilson's selection first. The extra cost will be made up in quality.
