Beyond 4G, everything communicatesProfessor Mikael Skoglund
intends to make the future wireless communications society more
cost-effective and environmentally sustainable. All in order to
make peoples daily lives easier.
We cant just keep aiming at higher speeds and greater
bandwidths, we must startlooking seriously at energy systems, says
Mikael Skoglund, Assistant Dean of theKTH School of Electrical
Engineering from January 2009.
Wireless more cost-effective and env ironmentally
sustainable
This "total" wireless communication has the potential of being
much more costeffective than using cables. There are considerable
savings to be made in manyindustrial applications, for example
there is no need to fit cables for communicationbetween different
machines.
Another driving force behind new theories and technologies in
this field is the need tosave energy in future systems. Today's
mobile communications account for a far fromnegligible part of the
world's total energy consumption, and this is attractingincreasing
attention. For example, in EU calls for new research in the area,
Green ICT has now become asignificant part of the budget.

Performance for the Communications Society
Communication Theory for the wireless communication society
concernshow to transfer more information - audio and video via
wireless units - atlower cost, lower power consumption and with
higher performance levels.Mikael Skoglund develops mathematical
theories and algorithms for transmission and storage of information
into a working capacity andefficiency that far exceeds the level
currently available.
Making daily life easier, automatically
In order to research into the technology needed to make
everythingcommunicate, more collaboration across subject boundaries
is essential. Michael Skoglund cooperates withKarl Henrik Johansson
and Mikael Johansson at the Department of Automatic Control.
The aim of this research is to make people's daily lives easier
using automatics. Technology is becomingmore and more embedded,
while striving to use natural resources as efficiently as possible.
This can beillustrated by traffic management which also has a major
impact on environmental emissions. With suchtechnology it is
possible, as the Japanese are already doing, to channel traffic
onto motorways in order for ito flow freely. When motorists do not
need to queue up with their engines idling, they do not emit as
much
carbon dioxide.
In this example it is the algorithms, in terms of communications
theory, which transmit all the data and gathinformation, while the
automatic control technology takes care of traffic management, says
Mikael.
