Forschungsgruppe IP-basierte Kommunikationssysteme

Labor für Kommunikationssysteme



IKT is an institute associated with Ostfalia - University of Applied Sciences, which specializes in the research and development of technologies and solutions for IP based communication services, networks and applications. This includes wired as well as mobile communication.

Currently our main topics are Software Defined Networking (SDN) and Network Function Virtualisation (NFV). Our applications focus for these technologies are mainly Network-as-a-Service (NaaS) for Cloud-IT and Industrial Internet of Things (in Germany known by the term „Industrie 4.0“ ). Development, implementation and conformance as well as interoperability tests for communication protocols and network elements are part of our offering.

Before, we had our main focus on Voice-over-IP (VoIP) and Next Generation Networks (NGN), in particular on specialized applications of these technologies for railway related communications as well as critical communications.

Contact us if you are currently searching for a partner to collaborate with in designing and prototyping solutions within your application field.

Kooperationsformen und -partner

In den letzten Jahren hat das Fachgebiet Telekommunikation in unterschiedlicher Form mit verschiedenen Firmen und Organisationen der Region kooperiert. Dazu gehören z.B. Machbarkeitsuntersuchungen und Prototypenentwicklung sowie Netzanalysen und -entwurf im direkten Auftrag, Technologie-Entwicklung im Rahmen geförderter Forschungsvorhaben, Gutachten oder Schulungsmaßnahmen. Einige Kooperationspartner der letzten Jahre sehen Sie unten.
