The rapid growth of high-data-rate applications along with the fact that the majority of mobile data traffic is originated indoor has drawn much attention on IBW (In Building Wireless) solutions, from industry to academic research. The mobile network operators seek proper indoor solutions to accommodate the high indoor traffic demand for their future network evolution. In this thesis, we study the dedicated indoor systems for enterprise solutions.The DAS and Femtocells constitute two major IBW solutions for efficient in-building coverage extension and capacity provision. This study makes a technology economical examination based on these two systems for network evolution using the LTE technology.The performance is evaluated based on simulations. Overall, the DAS is less efficient in providing high speed, high volume mobile data services than the multi-cell system, i.e. the Femto system and the proposed centralized coordinated scheduling system. The proposed system is proved capable of achieving the best overall performance.Subsequently, we conduct the financial economic analysis for indoor DAS and Femto systems based on the TCO analysis. For very high data-rate in-building deployment, the Femto system has absolute advantage compared to the DAS. For coverage-oriented deployment with very limited user data traffic demand, DAS is the most economical solution in large-size buildings, and Femto is more economical for deployment in small-size buildings
