Strategy to improve the indoor coverage for mobile station

This paper presents an evaluation of whether the indoor signal strength for commercial buildings fulfills the cell planning requirement. In order to provide high quality cellular service, it is necessary to place an array of distributed antennas connected using feeder cable within the building. With the feeder cable approach, splitters and computer software, we develop using Visual Basic 6.0. The effective radiated power (ERP) at the distributed antenna can be calculated and it can also be predicted how far the signal can go with the calculated ERP. This design process can be used to obtain an estimated indoor system requirement. All of the requirements can be achieved by applying the method in this paper.
