Converging networks laboratory

Interoperability and co-operation between networks, applications, services and products is still mostly lacking. One possibility to better understand convergence is to build prototypes and test products in a laboratory environment.

VTT’s Converging Networks Laboratory (CNL) collects new radio interfaces, novel services and research prototypes in one place, in a laboratory-scale converged environment.

On our premises we have WCDMA/UMTS, HSDPA, fixed and mobile WiMAX (802.16 d/e) and Wi-Fi networks, which are also configurable (e.g. QoS can be changed). VoIP, IPTV and video streaming services are found at the laboratory. New services can be created either as stand-alone servers or by utilising an application server connected to the IP Multimedia Subsystem (IMS). Mobility is maintained with IP mobility management solutions.

The laboratory is physically connected to the Internet, to a local city Wi-Fi network with 600 access points and to a cellular Octopus 2G/3G MVNO test network allowing global exploitation.

The main research topics are related to convergence, network co-operation, end-to-end performance, testing and multimedia adaptation. We also show demonstrations created in top European research projects, thus providing insight into future technologies and innovations.

We have several options for companies, universities and projects to participate in the laboratory program.

Customers benefit financially by outsourcing their R&D and testing to CNL since expensive investments in hardware and competence development are handled by VTT.
