“…The basic value proposition is that the cost of the femtocell itself is greatly outweighed by the savings from offloading traffic from the macrocellular networks [113]. These findings appear to be true across a range of market segments from residential to enterprise users.…”

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.

“…To improve the Quality-of-Service (QoS) for their final users (FUs) and to ensure that every FU can receive wireless service, the WOs can provide monetary incentives to these FAPs for their cooperation [4], [5]. By utilizing the FAPs, the WOs can extend their coverage and also offload the traffic of their MAPs [6], [7]. FAPs can communicate with MAPs in practice, and WOs through dedicated broadband connections [8], [9] and can only handle a limited number of FUs [1].…”

We propose distributed matching algorithms for an uplink communication network comprised of multiple femtocell access points (FAPs), multiple wireless operators (WOs) which own multiple macrocell access points (MAPs) and multiple final users (FUs) subscribed to these WOs. In particular, we propose two algorithms: the first algorithm matches the FAPs with the final users (FUs), the resultant matchings of which are then used for the second matching to match the FAPs with the WOs. The key idea behind the proposed algorithms is that the FAPs aid the transmission of the FUs belonging to the WOs by (i) increasing the WO's coverage and (ii) reducing the traffic load of the WO's macrocell access points (MAPs), and in exchange, the WOs provide monetary compensation to the FAPs. We prove that both of the proposed algorithms converge to a group stable matching. Numerical analysis also reveal that the proposed distributed algorithms achieves a performance close to a centralized method, with much less overhead.

“…And while some papers clearly state the benefit of macrocell to small cell offload for both the macro and small cell users [10,11], none can be found that propose a joint macro/microcell approach to maximise this offload nor can any references be found on MDT based methods for optimising clusters/linear deployments of lamppost mounted 3G/WCDMA microcells.…”

Abstract-This paper presents a number of Self-Organising Network (SON) based methods using a 3GPP Minimisation of Drive Testing (MDT) approach or similar and the analysis of these geo-located UE measurements to maximise traffic offload onto lamppost mounted 3G/WCDMA microcells. Simulations have been performed for a real 3G/WCDMA microcell deployment in a busy area of central London and the results suggest that for the network studied a traffic increase on the microcell layer of up to 175% is achievable through the novel SON methods presented.
