Network Evolution and QoS Provisioning for Integrated Femtocell/macrocell Networks

Free registration required

Executive Summary

Integrated femtocell/macrocell networks, comprising a conventional cellular network overlaid with femtocells, offer an economically appealing way to improve coverage, quality of service, and access network capacity. The key element to successful femtocells/macrocell integration lies in its selforganizing capability. Provisioning of quality of service is the main technical challenge of the femtocell/macrocell integrated networks, while the main administrative challenge is the choice of the proper evolutionary path from the existing macrocellular networks to the integrated network. In this paper, the authors introduce three integrated network architectures which, while increasing the access capacity, they also reduce the deployment and operational costs.
