This paper provides an overview of the use of small cells (eg, femtocells) in the Internet of
Things (IoT) environments. As a result of rapid increase in the number of mobile connected …

Increase in system capacity and data rates can be achieved efficiently in a wireless system
by getting the transmitter and receiver closer to each other. Femtocells deployed in the …

The use of small cells serviced by low-power base stations such as femtocells is envisioned
to improve the spectrum efficiency and the coverage of next-generation mobile wireless …

A fundamental choice in femtocell deployments is the set of users which are allowed to
access each femtocell. Closed access restricts the set to specifically registered users, while …

Extensive deployment of heterogeneous small cells in cellular networks results in ultra-
dense small-cell networks (USNs). The USNs have been established as one of the vital …

Cellular operators have been offloading data traffic from their licensed bands to unlicensed
bands through a large number of WiFi hotspots over the past years. Although this approach …

The design of distributed mechanisms for interference management is one of the key
challenges in emerging wireless small cell networks whose backhaul is capacity limited and …

Heterogeneous cellular networks (HetNets), where low-power base-stations are overlaid
with conventional macro base-stations, is a promising technique to improve coverage and …

For about the past decade and a half research efforts into cognitive radio networks (CRNs)
have increased dramatically. This is because CRN is recognized as a technology that has …

Many cellular user equipments (UEs) today are able to access both the unlicensed band
(eg, via WiFi) and the cellular licensed band. However, in most regions of the world, they are …
