The interference management and cost analysis perspective of femtocell in 4G network

Telecommunication has seen distinct upgrade since the innovation of wireless communication. The latest addition is LTE-Advanced. LTE-Advanced requires implementation of femtocell. Spontaneous femtocell deployment introduces cross-tier and co-tier interference as well as further cost for uniform installation. In this paper, we describe outlines to solve the encountered problems and discuss the feasibility of the proposed outlines. The outlines contain efficient reuse of macrocell RF channels to indoor femtocells by dynamic spectrum allocation. The autonomous, Cognitive Radio-enabled technology is the premise of femtocells driven by LTE-Advanced. Cognitive Radio ensures offloading from macrocells by craftily imparting over accessible range. Application of on Access Control List concept further enhances femtocell capability. Additionally, hardware and software deployment costs are matched with macrocell. The reservations aim to satisfy the criterion identified as Quality of Service. The choice of femtocell over WLAN is favored by considering authorization and co-existential constraints.
