changes societal structures on an increasing speed. The new
architectures of ICT platforms and services act as enablers of new
market architectures and business models, first within the ICT sector
itself and gradually on all other vertical industries. This lecture
consists of examples of new technologies that potentially act as
enablers of anticipated ecosystem changes. Examples include
software-defined networking (SDN), information centric networking (ICN),
embedded SIM, multipath TCP, and cognitive radio.

the data markets necessarily fail?
Professor of practice Pekka Nikander
Assume we have data. Lots of it. And it is useful. How do we get it used throughout the society? The trivial answer of creating "data markets" appears to be hideously complex, due to data being an anti-rival production factor.
This lecture drills up from the Distributed Ledger Technologies, which enable Open Digital Platforms or marketplaces, into what kind of new economic structures are likely to be needed to enable widespread industrial data reuse.

Communication systems today are
characterized not only by the transport of traffic between two
communication endpoints, but also by the interaction with physical
environments. In the upcoming Internet of Things, an enormous number of
devices that bridge between the physical and the digital world is
envisioned, sensor networks can be employed to monitor physical and
environmental stimuli and on-body networks and wearable devices extend
these capabilities to breach into very personal, private domains.
the above scenarios require to (1) capture and process environmental or
personal stimuli and to (2) protect and secure the communication of
such data for privacy reasons. Ambient Intelligence addresses research
issues in these domains.

Extreme Mobile Broadband is a main component of the new 5G New Radio. The objective is to further increase the capacity of mobile networks. Capacity can be increased in three directions: by densifying the networks, by using more bandwidth, and by increasing the spectral efficiency. Massive multiuser MIMO (mMIMO), where the number of base station antennas grows to hundreds, is the only known method to significantly boost the spectral efficiency of wireless transmissions. To find more frequency resources, larger chunks of bandwidth are available In high frequency (millimeterWave) frequencies. Due to small antenans, mmWave service necessarily happens over short distances, so mmWave networks are necessarily also dense networks. Also, significant amounts of antennas are needed to ensure sufficient receive power. Using the antennas for transmission makes mMIMO a natural technology in mmWaves. To keep ths cost of RF-hardware tolerable, hybrid digital-analog architectures have to be considered.
5.11.2019, 10-12, T2: Software Defined Networking for Datacenters and the Wide Area
Professor Raimo Kantola
The lecture describes the approach of Software Defined Networking (SDN)
and its applications to single admin networks and the wide area
networks. SDN separates the control plane from the data plane in
networks. The data plane will be providing packet forwarding and
mangling - the idea is to keep the data plane nodes simple and they will
execute rules set by the controller. This will have many advantages,
such as the possibility of implementing centralized algorithms that use a
network wide view, ease of introducing any experimental services and
flexible and fast provision of transport services. It is expected that
the SDN will have a major impact on the way operators do business in the
networks, SDN also open opportunities for new players to come in. SDN
is often implemented in conjunction with virtualization. This means that
e.g. the control plane software is executed in virtual machines rather
than on physical computers. The lecture identifies the research
challenges related to SDN.
