Title: "A Survey on Spectrum Management in Femtocell Networks"

Abstract:

Femtocell technology is regarded as a promising way to deal with poor indoor 
coverage and increase spectrum spatial reuse. Femtocell Base Station (BS) can 
be easily installed by end users and connected to service providers’ network 
through broad line. End users benefit from better coverage, higher transmission 
rate while Wireless Service Providers (WSPs) can offload traffic from expensive 
macrocell and improve the Quality of Service (QoS). One of the key challenges 
facing femtocell is spectrum management, which brings both technical and 
economic issues. On the one hand, spectrum management determines 1) the 
cross-tier interference between macrocell and femtocell; 2) intra-tier 
interference among femtocells, which further impacts the overall throughput of 
the network. On the other hand, spectrum is scarce resource that should either 
be purchased or opportunistically accessed. Utility-oriented WSPs have to 
balance the spectrum acquisition cost and network performance before making 
their decisions. In this survey, we first introduce some background knowledge 
about femtocell. Then we summarize key challenges in spectrum management in 
femtocell network from technical perspectives. Finally, some possible business 
models are described. Existing research works and our considerations are 
presented to give potential solutions for these challenges.
