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

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 …

Femtocells are designed to co-exist alongside macrocells providing higher spectrum
efficiency, spatial frequency reuse, to name a few. However, when deployed in the two-tier …

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

Femtocells are aimed at providing strong coverage in the indoor area where typical
macrocell coverage is very poor. It has hugely attracted network operators and stakeholders …

Femtocell is considered to be one of the most promising solutions for future indoor wireless
communication. Due to the scarcity of spectrum resources, femtocells need to share the …

The interference problem is a bottleneck of femtocell development as more and more
femtocells are deployed. This paper considers interference from macro-cell as well as …

This chapter introduces the concept of cognitive femtocells and examines how the cognitive
capabilities can enhance the operation of femtocells. First, basics of femtocell networks are …

Femtocells have emerged as a promising solution to provide wireless broadband access
coverage in cellular dead zones and indoor environments. Compared with other techniques …

The deployment of low-power nodes such as femtocells within the macrocell's coverage
area is one of the main features of future 5G networks. However, challenges arise in the …
