“…Das and Ramaswamy in [29], [30], investigated the reverse link (RL) capacity of femtocells, modeling inter-cell interference as a Gaussian random variable. As discussed in Section IV, such a model is probably not accurate for cellular systems with femtocells.…”

Abstract-Femtocells, despite their name, pose a potentially large disruption to the carefully planned cellular networks that now connect a majority of the planet's citizens to the Internet and with each other. Femtocells -which by the end of 2010 already outnumbered traditional base stations and at the time of publication are being deployed at a rate of about five million a year -both enhance and interfere with this network in ways that are not yet well understood. Will femtocells be crucial for offloading data and video from the creaking traditional network? Or will femtocells prove more trouble than they are worth, undermining decades of careful base station deployment with unpredictable interference while delivering only limited gains? Or possibly neither: are femtocells just a "flash in the pan"; an exciting but short-lived stage of network evolution that will be rendered obsolete by improved WiFi offloading, new backhaul regulations and/or pricing, or other unforeseen technological developments? This tutorial article overviews the history of femtocells, demystifies their key aspects, and provides a preview of the next few years, which the authors believe will see a rapid acceleration towards small cell technology. In the course of the article, we also position and introduce the articles that headline this special issue.

“…Coverage and capacity analysis of small cells, focusing on the downlink, has been undertaken in [7,8]. Reverse link capacity results for small cells and modeling results for inter-cell interference are provided in [9]. They modelled interference as a Gaussian random variable which is not always consistent with practical systems.…”

Performance of outdoor small cells with co-channel deployment of macro cells for DS-CDMA systems is considered in this paper. Although interference management techniques, such as self organising networks, have been developed and to some degree deployed there are many open issues especially related to the performance of small cells. Small cells address outdoor hotspots and have different characteristics to indoor self-installed femtocells, including higher power levels and open subscriber group connectivity. This paper describes downlink performance results to better understand key parameters and trade-offs for these co-channel deployments. We describe the parameter configuration, the amount of offload achieved, and throughput for users connected to small cells. The results show that orders of magnitude of throughput improvements can be achieved when as little as four small cells per macro are deployed. We also discuss self optimisation use cases and show some motivating performance results.
