Direct image link with the event's authorities aim more and more often. Drones buzzing around easily in the sky, but whether their mediated image transfer enough quality?
the university of Oulu pulled by the Priority-process research and develop authority and etäyrityksille directed to the operation of critical communication solutions. Involved in the research consortium of research institutions (Centria and Turku universities of applied sciences), VTT, the authorities (in mm. Armed forces and rescue services) as well as companies.
Included are, for example, Airbus, Digital, Keysight, Exfo and Bittium.
the Goal is to find new innovations, what does the 4G and the 5G technology can be utilized. The current Virve-network alongside the comes wireless 4G and 5G networks in a working system, which take advantage of broadband data capabilities.
at the university of Oulu's excellence in data communication and it security development. Head of research Harri Posti by now to find out how commercial networks can be used safely in various parts of Finland, where, and when authorities may require it.
authorities have extreme needs, for example, security, availability and reliability, which are not as stringent as in the ordinary data traffic. Research to figure out now, how 4G and 5G-technology meets these authorities needs, Harri Posti images of more than seven million in the process.
the Same problem is to be resolved around the world, as adequate data transmission systems, the need is growing also in the business world.research manager Harri Posti, now witness to a global paradigm shift safety authority of communications.Marten Lampén / yleverkko connections functionality will solve traffic
Harri Posti take for example, a remote railway or highway in the event of a major accident. Commercial operators are not necessarily built for that kind of areas of the network, which would be sufficient to serve the authorities demanding a temporary need.
– the 5G network will bring more spectrum, more capacity, higher data speeds, which can be utilized in the future also machines in the communication between, Harri Posti said.
the Priority of the process is now examining the opportunities, how can we quickly create a sufficiently capable broadband connection to crisis situations.Small, red dots in the photos are the 5G network of the antenna elements. Marten Lampén / Yle
the Transport - and communication agency trafi ' s leading expert Heidi Himmanen said that the problem is also that the mobile network is designed to be used from the ground and from the air. They are not designed to support droonikäyttöä.
mobile networks functionality and quality is currently estimated at one and a half meters from the ground surface.
Himmanen, according to the drone could also provide temporary support of the station platforms.
– 4G networks now cover 99% of the population and largely roads. In remote areas this coverage will not be uniform, and some regions of the network capacity to compete, while users are much, Heidi Himmanen said.
These broadband performance related issues resolved now. When official communication is transferred to commercial networks, because it is reserved viipaleensa broadband, but its sufficiency is to be guaranteed even in crisis situations.Antenna signals can be to study the disruption of this device.Marten Lampén / Yle5G and the internet of things
the Next decade expanding the 5G technology also allows machines and goods between the speed of communication. Ordinary citizens in everyday life this might not be that revolutionary new, but already commercial operators are built closed to the 5G network, for example ports and factories.
the Priority-process is also involved in Land - and forest owners the central union of MTK, as the farms need the data traffic is increasing all the time. Cow of the life and crop growth will be monitored digitally.
the MTK development director Markus Lassheikki expects that the project will generate solutions on how the bio-economy companies in terms of sufficient capacity of broadband can be used to create technically and cost-effectively to areas where broadband normal construction is not in sight.How to 5G-technology message protection can be achieved?

their Own micro networks of construction does not, however, succeed, because the frequencies have been handed over to commercial operators.
– Now let's talk about, can we afford to frequencies also local activities other than commercial mobile operators use, Heidi Himmanen said.
This is the experience of other countries and the university of Oulu research manager Harri Posti will keep the idea of at the discretion of the worthy.
– Technical solutions, what we study and create our authorities, are largely also available to the commercial side.
with This he also means the traffic safety solutions.
– an Area that has a pretty multi-dimensional thing. It is reliability, availability and data security, the Post describes.
