Abstract: Femtocell is a miniature base station installed in subscriber’s residence and office for providing cellular service within the local home/office environment. Femtocells extend the coverage of an operator’s existing macro network and thereby improve a user’s voice and data experience. In addition, femtocells offload traffic from the macro network, which helps to solve the capacity crunch faced by operators due to exploding data demand on their macro networks. While femtocells improve a user’s coverage and throughput, they also cause interference to existing macro networks. Qualcomm has developed a suite of techniques to manage interference on both forward link (FL) and reverse link (RL) for robust performance in 1xEV-DO femtocell deployments.
