DCU Strategic ICT Research

Networks and Communications Engineering

This forms a large part of the research agenda of the School of Electronic Engineering at DCU. The focus on next generation telecommunications research includes - Performance Engineering, Radio & Optical Communications, RF Modelling and Simulation, Switching and Systems, and Network Processing.

40G/100G Low Cost Optical Pulse Source
A high speed pulse source that can be used in next generation 10G, 40G and >100G bps optical communication systems. The solution is smaller, cheaper and more efficient than traditional technologies. It can also be used in medical imaging, chemical analysis, microscopy and others

Next Generation Indoor Wireless Technologies
The research team in the RINCE Institute have developed a number of novel optical platform technologies including a simple and inexpensive optical comb source. This platform technogy coupled with the group's experience in both optical and radio frequency engineering has created a number of new commercial opportunities in wireless distribution of HDTV in buildings and NG high speed optical access networks

Hybrid Radio / Fibre Distribution Systems
Hybrid radio/fibre distribution systems - NG broadband wireless network solutions using microwave radio links (10-100GHz) and optical fibre distribution in core network to connect base stations.

Optical Signal Characterization for High Speed Optical Networks (>40G)
Optical signal characertization to support next generation high speed optical networks >100Gbps that are currently being deployed.

Hardware-based Architectures and Algorithsm to Improve IP Router Performance
Algorithms to enable improved peformance (power consumption, speed, scalability and cost effectiveness) of Deep Packet Inspection (DPI) hardware in routers to enable more widespread deployment of the technology for improved security and multimedia traffic management.
