This work presents an estimation of the global electricity usage that can be ascribed to
Communication Technology (CT) between 2010 and 2030. The scope is three scenarios for …

Heterogeneous networks, HetNets, are known to enhance the bandwidth efficiency and
throughput of wireless networks by more effectively utilizing the network resources …

To tackle the challenge of providing higher data rates within limited spectral resources we
consider the case of multiple operators sharing a common pool of radio resources. Four …

In this paper, we propose a new approach for optimizing the handoff decision in femtocell
networks using Hidden Markov Model. To do so, we formulate the handoff problem as an …

A method in a network node for enabling proximity detection is presented. The network node
is comprised in a wireless communications network and serves a wireless device. According …

The performance of centralized and distributed deployments of massive MIMO in an office
building is analyzed both with and without cooperation. It is shown that using twice as many …

Deployment of femtocells with a small coverage range in wireless networks leads to a
frequent handover initiation. The problem is more crucial when femtocells operate in an …

Femtocell deployment will play a key role for the wide adoption of LTE-Advanced, as it
brings the access network closer to the end user in a cost-effective manner. This disruptive …

This paper presents a theoretical investigation and experimental implementation of indoor
radio-over-fibre (RoF) using polymer optical fibre. We characterise the system based on the …

In two‐tier networks, which consist of macrocells and femtocells, femtocells can offload the
traffic from macrocells thereby improving indoor signal coverage. However, the dynamic …
