3GPP LTE(Long Term Evolution)/LTE-A(LTE-Advanced) are the evolution of the UMTS which are successfully commercialized in Korea and these make possible to deliver high quality multimedia services according to the users' expectations. In the more than two years since, it has been increased of a number of users and total amount of data in LTE network. And there is a limit to budget for investment of each communication company. The investment in LTE/LTE-A, it is closely related to enlarge in-building coverage. LTE/LTE-A network engineers need new Re-engineering scheme and technology to reduce cost and ensure enough in-building coverage. In this paper, we describe how to handle LTE traffic occurred in building with (Density per Sector: Non-Uniform) technique in simulation tool. And we explained on the application of different penetration loss according to the each class of building. These functions can give more reliable analysis results to increase the in-building communication quality in LTE/LTE-A.
