Centria's Test Network Environment

Centria’s test network environment offers a real platform developed over time using commercial base stations and network management systems. Centria provides a state-of-the-art expertise and test platform for research, trials and demonstrations for all partners. Test network environment is located in Ylivieska town in Bothnia area, Finland.

 

Test network environment has evolved according to the demands of each trial. In previous projects Centria’s test network environment and knowledge has been utilized in multiple research topics. Several research, proof-of-concept trials and public demonstrations has been carried out in Centria’s test network environment. The field test environment is a heterogeneous network build with commercial hardware and software components. The test network environment consists of several base stations and sites and is well connected nationwide in Finland with other test environments enabling versatile end-to-end testing in large-scale test environment.

 

 Centria's test network environments timeline.

 

Centria has world-class knowledge and practical skills for testing and configuring, as well as maintaining and building mobile network. Centria’s test network environment acts as a verification platform for LTE and 5G research. The focus is on developing new types of testing methods, applications and research from the communication technologies point of view for verticals such as testing technology, drone communication, critical communication, industry, agricultural technologies, robotics and automation.

 

Current test network offers abilities for following technologies:

  • TDD-LTE operating at band 40 and 42 for both outdoor and indoor coverage.
    • Band 40 (2300 MHz) has 40MHz channel and covers both Centria indoor, campus area and Ylivieska city centre and vicinity. Band 40 constitutes of three sites two higher towers, campus indoor, and rooftop mast hosting pico cells, small cells and macro cells and one massive MIMO system (11 eNB’s in all).
    • Band 42 (3500 MHz) has 60 MHz channel and covers both Centria Campus indoor and Campus outdoor coverage. Band 42 constitutes mainly indoor small cells and macro cell (3 eNB’s).

 

The ongoing global 5G and 6G research and standardization progress are followed closely and therefore upcoming 5G updates include:

  • Utilization of band n78 with 60 MHz channel outdoor test network close to Centria Campus for example for outdoor to indoor penetration path loss measuring to mention one case.
  • Implementation plan of first 5G Non-Standalone during 2019 and later 5G Standalone during 2020.

Previous research, proof-of-concept trials and public demonstrations include 3D antenna radiation pattern measurements [1] [2], detecting RF interference source [3], Massive MIMO and beamforming trial [4], Smart traffic [5], Active Antenna System (AAS) [6] [7] [8], Licensed Shared Access [9] [10] and Shared Access Spectrum [11] [12] demonstrations. The test network environment is continuously developed for the needs of future mobile networks and communication. In previous research projects, Centria has been developing e.g. new intelligent 3D measurement methods for mobile networks by using unmanned aircrafts and developing 3D map importer tool to combine network measurements to create a new way to propagate network planning, optimization and simulation.
