CNL Democompetition Results

Demoparty 2016

The 4th Annual CNL Demo Competition

Ten different project groups were competing for the CNL Trophy in the "CNL Democompo" finals, which was held on 15th of December 2016 at VTT. The Trophy is awarded to the best technology demonstration voted by the audience.

The competition entries varied from 5G radio and antenna solutions to cyber security, quality of service, IoT and gaming applications. The 5G development was one of the main topics also this year.


The demo competition event has been now arranged in four consecutive years. The idea for such event realized about 5 years ago when we had some discussions in our management team about the lack of information exchange between our researchers, line managers, customer services and business development. The traditional seminar presentations seemed to be too stiff and insufficient to inveigle people into good discussions. So, we wanted to try something else and to do it in little bit more "tongue-in-cheek" style.

The idea for competition came up from mixing the "old school" computer demoparties' demo compos with our traditional ICT demo presentations. One of the main targets was also to push the demonstrations and presentation towards more visual and easily understandable form.

The first event was purely VTT's internal, targetting for information exchange and co-operation between different research projects' researchers in Communication Networks research area.

For the second year, the event was enlarged to cover also other projects, which were utilising the CNL test network services and were related to our ICT research.

The third "Demoparty" was the first event, which was also open to our customers and project cooperation partners. We hope that in future we can extend the event to include even more collaboration with our partners.

Summary of 2016 Demo Entries
  • Entry #1: Cyber Security Fish Tank - Tietoturva-akvaario
    • Cyber security fish tank is an experimental network security monitoring visualisation solution based on Unity 3D platform. This solution enables presenting the human-user in meaningful ways large amounts of data on network traffic and detected anomalies both in real-time and using recorded historical data. The aim is to visualise data in a way that also non IT-expert can notice the anomalies in network traffic.
  • Entry #2: Virtualized Video Service Deployment in the Cloud
    • This demonstration will showcase a smart, on-demand video delivery solution, enabled using lightweight virtualization and distributed cloud computing technologies. The solution allows dynamic setup, scaling, and management of transcoding and content delivery services, depending on the current resource needs and availability. The solution uses information collected from the computing resources, network, and end-users in making intelligent decisions regarding dynamic setup and placement of virtualized edge servers and transcoding services within the distributed cloud environment. This simplifies the setup of video delivery services and improves the usage and sharing of computing resources in the cloud, considering also cloud resources at the edge of the network. The solution targets for cost and time savings in video service deployment, maintenance, and operation compared to current solutions running on dedicated hardware or fixed cloud resources. Furthermore, optimizations in network traffic are achieved by bringing the content and transcoding services closer to the end users.
  • Entry #3: Smart 2.4GHz Antenna for Direction of Arrival Estimation Algorithm
    • The demo demonstrates the adjacent pattern power ratio (APPR) direction of arrival (DoA) estimation algorithm and a simple tracking algorithm for the smart 2.4GHz antenna. The demo uses LTE downlink with VTT smart antenna connected to the user equipment side. DoA estimation algorithm and antenna beam direction control have been implemented using LabVIEW in the control PC. The demo was done in AWARENESS project.
  • Entry #4: Power Saving in Video Transmission
    • All forms of videos constitute over 80% of total IP traffic implying that even a small power reduction could lead to substantial energy savings helping in its part to achieve the ambitious cuts in carbon dioxide emissions. In this demonstration, we present methods to reduce power consumption and show that by using these techniques in current hardware/software substantial energy savings could be achieved in the headend, network and terminals.
  • Entry #5: Crowd Interaction with TinyNode
    • INSIST Sensor demo is based on a crowd competition arranged in Rotuaari Piknik 2016 and Pikkujoulupiknik 2016. In this competition, crowd members bounce a beach ball. A sensor is attached on the ball which sends data to a server, which in turn interprets the movement of the ball. The crowd sees a prize raffle visualization on a large screen. As long as the crowd keeps bouncing the ball, the raffling keeps going, and whoever possesses the ball when raffling stops wins the indicated prize. This demo was witnessed roughly by 5000-10000 people during Rotuaari Piknik event and over 5000 people in Pikkujoulupiknik.
  • Entry #6: Mobiilimittari
    • Mobiilimittari is a service for measuring primarily mobile broadband connection quality, which allows you to test your subscription performance anywhere in Finland. The goal is to help customers selecting a mobile broadband subscription, by providing free and easy-to-use measurement service.
  • Entry #7: Sensor Mesh as a Wakeup Radio for Enhanced Energy-Efficiency
    • The idea is to increase energy-efficiency of wireless networks by using low-power sensor mesh as wake-up-radio. This is done by creating a Hybrid WiFi & Sensor mesh network by integrating sensor mesh nodes into WiFi mesh nodes this way providing a capability to monitor as well as to control WiFi mesh with bluetooth low energy wireless sensor network. This all can be visualized by using NetVizer network visualization tool.
  • Entry #8: 5GTN Monitoring - The Gaming Use Case
    • We demonstrate measurements and visualization of our 5G test network - the 5GTN. Participants can play networked FPS games over the 5GTN and see some of the information gathered from the network. There could even be chance to challenge our superhero gamers Zynster or Master Jinxhu while evil Teemu will try to cause problems for the gamers by hoarding the bandwidth with 4k video and IoT data. The audience can see all the action through a magnificient dashboard of colorful lines in full 4K resolution showing fancy measurements from the network.
  • Entry #9: TinyMeshNode & Eventbus - Reliable and Efficient IoT Networking
    • TinyMeshNode compounds VTT Tiny Node and Wirepas Connectivity technologies onto a single-chip, producing a low energy sensor node with efficient Bluetooth LE communication features. In order to add connectivity to the sensor mesh, a VTT Eventbus solution is implemented. The mesh cluster operation (e.g. network nodes, their connections, and sensor data etc.) can be visualized by using NetVizer network visualization tool.
  • Entry #10: 5G Network and Indoor Coverage Measurement with a Robot
    • Laser-based SLAM (simultaneous localization and mapping) provides accurate location information, which can be utilized to analyze network coverage and to develop indoor positioning systems. A live demonstration of a robot mapping its environment in the event venue.
