Femtocell architecture involves the use of two separate layers-the macrocell and femtocell
layers. In this architecture, the former is the conventional cellular network, whereas the latter …

The aim of this paper is to optimize femtocell performance by managing interference
between femtocell devices and between a femtocell and a macrocell. It achieves this using a …

The void spectrum in spread out geographical location and a congestion in spectrum
allotment in different regions of the world has led to the scarcity of precious natural resource …

As the demand for spectrum increases and frequency bands become more congested
especially in densely populated urban centres, spectrum managers are following diverse …

This paper presents an application of cognitive radio system concepts for the off-loading
operation of LTE networks by the opportunistic use of TV whitespace (TVWS). A flexible …

A major challenge for cooperative cognitive radio networks is the creation and optimisation
of a suitable spectrum portfolio, utilised by the radio nodes in the process of dynamic …

Wireless communication has involved relentless years of research and design and
comprises cellular telephony, broadcast and satellite television, wireless networking to …

Femtocells have been introduced as a solution to poor indoor coverage in cellular
communication which has hugely attracted network operators and stakeholders. However …
