The
evolution of radio access technologies (both for mobile cellular as
well as for broadcasting networks) is driven by the efficient usage of
the scare frequency ressources in order to fulfill the increasing
demand for high datarate services. Accordingly the upcoming air
interfaces (WiMAX, 3G LTE, DVB-H, ...) are based on the OFDM
technology.
This introduces new challenges in the domain of radio network planning,
i.e. to consider the properties of the OFDM technology in the
corresponding software tools. Based on the usage of appropriate radio
network planning tools the cost-efficient deployment of the radio
networks without limitations on the coverage performance should be
ensured.
Within the framework of the SIMPLON (SIMulator
for the PLanning of OFDM Networks) project, AWE
Communications will develop methodologies for the performance
assessment of OFDM based radio networks. The software package WinProp
shall be extended for the planning of OFDM radio networks, in order to
predict the expected coverage and capacity at system design, but also
allowing the efficient deployment of mobile cellular and broadcasting
systems based on the OFDM technology. The final goal for AWE
Communications is to develop a software package for the planning of
wireless OFDM
networks (like WiMAX, LTE or DVB-H).
SIMPLON is scheduled for 18 months, starting at Jan 01, 2009. The
project is co-funded by the BMBF
(German Federal Ministry of Research) within the KMU-Innovationsoffensive.
