    It is a problem of improving the antenna. This will only help on distance. Cell phones reduce the power output when close to a tower. The cell phone is optimized for the antenna they are using and it will do no good to just change the antenna. Your best bet is to make a reflecting dish and to focus the output to a smaller angle. Then all the power that you put out will go in the direction you point the dish. The receiving ability will also increase by having a larger capture area of the dish.
