Small cell networks (SCNs) are envisaged as a key technology enabling the fifth-generation
(5G) wireless communication system to address the challenge of rising mobile data demand …

Small-cell networks (SCNs), especially those operating in millimeter-wave bands, are
sensitive to blockages. In this letter, we develop a three-dimensional (3D) SCN model …

In this letter, we analyze the coverage probability in the dense wireless networks. This letter
is based on channel models that incorporate line-of-sight (LoS)/non-line-of-sight (NLoS) …

Today's heterogeneous networks comprised of mostly macrocells and indoor small cells will
not be able to meet the upcoming traffic demands. Indeed, it is forecasted that at least a 100 …

With the exponential increase in mobile internet traffic driven by a new generation of
wireless devices, future cellular networks face a great challenge to meet this overwhelming …

One of the promising solutions to meet the demands for ubiquitous coverage and high
capacity in heterogeneous cellular networks (HCNets) is the co-deployment of small base …

Ultra-dense network (UDN) is one of the most important techniques to support massive
number of different types of user equipments (UEs). It is essential to understand the impact …

In this paper, we present a new and significant theoretical discovery. If the absolute height
difference between base station (BS) antenna and user equipment (UE) antenna is larger …

Femtocells are viewed as a promising option for mobile operators to improve coverage and
provide high-data-rate services in a cost-effective manner. The idea is to overlay low-power …

To meet the current cellular capacity demands, proactive offloading is required in
heterogeneous cellular networks (HetCNets) comprising of different tiers of base stations …
