Performance of Open Access Femtocells in 4 G Macrocellular Networks

—This paper examines the open access operation of femtocells within a macrocellular network in which the same spectrum is available to both types of basestation. We examine the RF performance, particularly the interference levels, and using a generic 4G wireless protocol show the data rates that can be achieved. We present a mechanism to improve the data rate distribution, and consider the impact of changing the density of deployed femtocells.
