Leaky cable to indoor application

I am into 2g/3g design for indoor and instead of using antennas as signal tx/rx i will replace it by leaky cable. Yet my facts about leaky cable is not enough for the research.

I need to know the radiation pattern of the leaky cable and other important parameters.

The idea is to minimize the number of antennas installed in the buildings and replace the traditional coxial cable with the radiating leaky cables. It will provide the rf signal for the whole assigned coverage.

I need someone who is knowledgeable with Leaky Cables. Thanks.
