Capacity improvement via co-frequency small cells network

Due to the situation that the mobile data traffic grows rapidly and users continue to improve the quality of service requirements, the operators which are lack of part of the spectrum resources make a weak response. While precise deployment of small cell with the same frequency in the macro cell is a better solution. In this paper, the network analysis and verification result is shown which is in use of the system-level simulation and commercial LTE network. Although the macro cell and small cell deployment in the same frequency increases the network interference, it´s still able to obtain substantial capacity gains. Additionally, this paper analyzes the necessity for operators to deploy small cell in the same frequency, and offers the specific suggestion of implementation from the operators´ view.
