Abstract-Femtocells are small cellular telecommunication base stations that provide improved cellular coverage. These devices provide important improvements in coverage, battery life and throughput, they also present security challenges. We identify a problem which has not been identified in previous studies of femtocell security: rogue owners of femtocells can secretly monitor third-party mobile devices by using the femtocell's access control features. We present traffic analysis of real femtocell traces and demonstrate the ability to monitor mobile devices through classification of the femtocell's encrypted backhaul traffic. We also consider the femtocell's power usage and status LEDs as other side channels that provide information on the femtocell's operation. We conclude by presenting suitable solutions to overcome this problem.

Femtocells are low power base stations operating in licensed spectrum with the intent to improve coverage and performance of multimedia and broadband services. The femtocells provide a solution to improve indoor coverage of cellular mobile devices in the areas where the coverage is weak and intermittent while using macrocells. The use of data hungry devices such as, tablets, smartphones and other wireless devices are increasing rapidly with time and is a driving force for innovative ways in wireless communication to provide fast access to the internet, more capacity and higher quality of service. Femtocells can provide a useful way for mobile operators to offer a better user experience and deliver indoors broadband services consistently and reliably for a comparable context of application, distances, and obstacles. The proposed work will analyze the efficiency of femtocells in terms of its convergence along with WiMAX wireless technologies. The study will show how the coverage is improved by femtocells and how the total network capacity gains can be up to many times as compared to the current macro layer networks. This analysis will be based on more detailed performance parameters such as throughput, packet loss, packet end to end delay, download and upload response times for multimedia traffic. The femto access points (FAPs) will enhance data rates via improving link quality, shorter communication distance and less penetration loss resulting into increased capacity of the entire system.

In Fractional frequency reuse (FFR) based cellular networks which employ femtocells to fulfill the higher data rate requirements, the throughput performance of femtocells are primarily limited by the co-channel interference due to the frequency reuse. However, in orthogonal frequency division multiple access (OFDMA) systems, allocation of an optimum frequency subband based on the minimum interference present in all the available subbands, can improve the performance of femtocells considerably. This paper presents an energy based analysis related to the subband allocation considering the asynchronization effects of interfering signals occurring due to the propagation delays and timing offsets in the network. Based on the analysis presented here, a femtocell can be configured to provide improved performance by selecting a subband least affected by the interference.
