The concept of smart cities emerged few years ago as a new vision for urban
development that aims to integrate multiple information and communication
technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT
infrastructure and e-services should fuel sustainable growth and ...
The Internet of Things is considered to be the next big opportunity, and challenge, for the
Internet engineering community, users of technology, companies and society as a whole. It
involves connecting embedded devices such as sensors, home appliances, weather stations
and even toys to Internet Prot ...
How will future generations refer to our times? Will it be known as one
of space exploration, genetics, atomic energy or computing? Possibly,
but I think it is more likely to be ‘The age of communications’. Not since
printed books and newspapers were first introduced has there been
such an explosi ...
Engineers are professional inventors, researchers, and developers. Education imbues each engineer
with discipline-specific knowledge. Combining the different disciplines allows engineers to solve
more complex problems.
Currently, the information and communications technology (ICT) industry sector
accounts for about 2–6% of the energy consumption worldwide, and a significant por-
tion of this is contributed by the wireless and mobile communications industry. With
the proliferation of wireless data applications, wi ...
Thisbookfocusesontheemergingresearchtopic‘green(energy-efficient)wirelessnetworks’
that has drawn huge attention recently from both academia and industry. This topic is highly
motivated due to important environmental, financial and quality-of-experience (QoE) consid-
erations.Duetosuchconcerns,var ...
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling
and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations.
For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF
compon ...
To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation
(5G) mobile communication systems has been undertaken in recent years. It is expected that the spectral and energy
efficiencies in 5G mobile communication systems should be ten-fold highe ...
Many wireless communications channels consist of multiple signal paths from the
transmitter to receiver. This multiplicity of paths leads to a phenomenon known
as multipath fading. The multiple paths are caused by the presence of objects in the
physical environment that, through the mechanisms of pr ...
Transmit power in wireless cellular networks is a key degree of freedom
in the management of interference, energy, and connectivity. Power
control in both uplink and downlink of a cellular network has been
extensively studied, especially over the last 15 years, and some of the
results have enabled t ...
