is this Project about?
WiMAX with full mobility can be an alternative to existing and
evolving mobile networks. This can be either a complement or a threat
for incumbents’ mobile operations (GSM, UMTS). WiMAX with full mobility
needs an extensive co-operation in the standardisation and development
process, and agreements on hand-over and roaming.
IEEE 802.16e uses OFDMA (Orthogonal Frequency Division Multiple Access)
modulation whereas 3G systems are generally based on CDMA. OFDMA
certainly offers a range of advantages over CDMA, e.g. those regarding
propagation characteristics. However, available frequency bands for
WiMAX are less favourable for radiowave propagation than the 2 GHz band
allocated for UMTS. These differences pose interesting technical
questions and affect the techno-economics of both solutions.
are the main objectives of this Project?
- Conduct a technical analysis of the
mobile WiMAX standard, its current status and what is to be expected
in future developments (at the IEEE and WiMAX Forum and in the vendor
- Analyse the technical and economical
feasibility of mobile WiMAX in a selected set of deployment scenarios,
particularly in urban/suburban areas
- Analyse the financial benefits of
using mobile WiMAX in technically feasible scenarios
- Assess the threats imposed by mobile
WiMAX to other technologies such as UMTS
- Give an overview of the regulatory
environment of mobile WiMAX in a common European context as well as in
a selected set of individual countries
