Summary
The
evolution towards 5GB is considered to be the convergence of Internet services
with legacy mobile networking standards, leading to what is commonly referred
to as the ‘mobile Internet’ over Heterogeneous Networks (HetNets), with very
high connectivity speeds. Green communications seem to also play a pivotal role
in this evolutionary path, with key mobile stakeholders driving momentum
towards a greener mobile ecosystem through cost‐effective design approaches.
Moreover, it is becoming increasingly clear from new emerging services and
technological trends that the future is heading towards a digital world, where
not only end-users, but devices or things will be interconnected through a
wireless internet. This will give rise to new business models based on smart
applications, that will put in place new design requirements for next
generation mobile networks, the so called 5GB era , that includes energy and cost‐per‐bit reduction, service
ubiquity and high‐speed connectivity as desirable traits.
This
special issue targets some high quality research and practical case studies in
the very active field of reconfigurable transceivers, computational models for
big data and beyond that green networking for internet of everything (IoE)
applications to provide design recommendations for tomorrow’s ICT (Information
and Communication Technologies) networks. We aim to harness the fragmented
views on 5GB mobile communications to paint a more focused technology roadmap,
putting in place a clear set of challenges, requirements and proposals to
address the IoE challenges.

Green IoE for Smart 5G and beyond (5GB) Applications)
Abstract A 4-port multiple-input multiple-output (MIMO) antenna exhibiting low mutual coupling and UWB performance is developed. The octagonal-shaped four-antenna elements are connected with a 50 Ω microstrip feed line that is arranged rotationally to achieve the orthogonal polarization for improving the MIMO system performance. The antenna has a wideband impedance bandwidth of 7.5 GHz with S
11 < −10 dB from (103.44%) 3.5–11 GHz and inter-element isolation higher than 20 dB. Antenna validation is carried out by verifying the simulated and measured results after fabricating the antenna. The results in the form of omnidirectional radiation patterns, peak gain (≥4 dBi), and Envelope Correlation Coefficient (ECC) (≤0.01) are extracted to validate…
