A Survey on Spectrum Management in Femtocell Networks
PhD Qualifying Examination Title: "A Survey on Spectrum Management in Femtocell Networks" by Miss Yanjiao Chen 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.
