A survey on femtocells: Benefits deployment models and proposed solutions

Femtocell networks are considered to be a viable option that can fulfill the demands of high speed voice and data traffic for the indoor users. It uses the services of the existing broadband connection to connect to the operator core network. The cellular network operators need to modify the existing single tier macrocell network in order to provide the services of femtocells to its users. In this paper, we present a survey on femtocell deployment. Various aspects of femtocell networks in a diverse domain are discussed. A detailed analysis of the previous approaches is given to highlight their pros and the cons.
