Interference Control Technology for Heterogeneous Networks
To eliminate dead spots like home or office and let multiple users efficiently use limited frequency resources by providing a better mobile communication environment that enables high-capacity data transmission service, the demand for a small base station is increasing. Accordingly, the research for automatically minimizing the interference and increasing the capacity of the base station by optimizing the cell coverage has become necessary. For this purpose, extremely reducing the cell radius and providing a mobile communication environment for small business are needed. The femtocell services actively respond to the user's needs for a better mobile communication environment, and expanding business opportunities for the operators.
