distances. Integration of FSO and wired optical networks will
provide for seamless communication for many applications.
Network Localization and Navigation Systems:
This TC is
focusing on reliable localization and navigation, which is
becoming a key component for a diverse set of applications
including logistics, security tracking, medical services, search/
rescue operations, and automotive safety, as well as a large
set of emerging wireless sensor network (WSN) applications.
mmWave Communications and Massive MIMO:
combination of millimeter-wave frequencies and arrays with
a massive number of antennas will dramatically improve the
capacity and throughput leveraging on an unprecedented
spatial diversity and is another area being investigated.

Network Convergence of Satellite and 5G Architectures:
Inherent broadcasting and multicasting capabilities of satellite
systems have to be properly conjugated with the ongoing
evolution of wireless systems (namely, 5G), which is expect-
ed to provide an unprecedented increase in capacity and
number of served users. As such, satellite systems are expect-
ed to take part in the overall 5G picture, as integrated direct-
ly in the access segment as backhauling technology or in
the network core, where SDN/NFV concepts will play an
important function to enrich current services and enable new
services in the context of mainly multimedia and public safe-
ty applications.
Networking in the Sky through Satellite Mega-Constel-
The renewed interest in LEO satellite constellations
stems from the opportunity to deploy larger systems than
ever, offering large data rates, also owing to the use of free
space optics technology. The reduced latency offered, as well
as the increase in capacity, are expected to revolutionize the
world of telecommunication, although important research
challenges need to be addressed, especially with respect to
the complexity of routing operations onboard satellites.
Next-Generation Satellite Payloads for Very High
Throughput Systems:
The advent of high throughput satel-
lite systems and the more recent conception of ultra-high
throughput satellites is the logical response to meeting the
more stringent demands of users in terms of data rates. In
order to further optimize the available satellite capacity, the
resource allocation schemes currently in place should be
upgraded to more closely track traffic fluctuations. To this
end, an important role is played by satellite payloads which,
due to recent advances in space technology, enable more
flexible operations, for what regards allocation of frequency
and power (flexible payloads), and time (beamhopping).
Signal Processing for 5G and Integrated ICT Systems:
The advent of 5G technologies, combined with the prolif-
eration of wireless sensors and intelligent machines, have
brought multifaceted technical challenges for the design of
future communication system and networks. Advanced signal
processing techniques, such as massive MIMO and distrib-
uted antenna systems, millimeter wave systems with hybrid
analog/digital beam forming architectures, and full duplex
radios, need to be explored in achieving highly efficient trans-
mission in time-frequency-space domain. The use of small
cells and multi-tier structure bring direct challenges to the
highly cooperative signal processing techniques in reducing
the mutual interferences and supporting the massive connec-
tivity required by device-to-device related applications. The
ultra-reliable and low-latency communication, requested in
5G systems, call for advanced signal processing techniques
that can be implemented by a careful re-design of the exist-
ing ones.
Signal Processing for Big Data Analytics in Communi-
cation Networks:
The large amount of data generated by
connected devices (IoT) imposes formidable challenges on
future wireless networks, such as large bandwidth, large stor-
age space, and high energy consumption. Currently there is a
big gap between the resources required to support Big Data
in wireless networks, and the services that can be supplied by
current wireless network structures. These challenges can be
tackled by new signal processing techniques, such as low-di-
mensional and sparse signal representations, as well as signal
processing based on graph models.
The TC technology interests and directions, above briefly
described, might spark the curiosity of the readers to search
on the Technical Committee websites to learn more and
become actively involved and contribute to TC and ComSoc
activities. We expect not only to energize the present mem-
bers, but also to attract the many new members who are
needed for the continuing success of our Society. Trusting
the TCs’ core role is my bet for the near future of ComSoc.
