Workpackages

The workpackages, their objectives, approach and interactions are defined in the dedicated pages linked below/at side. The approach followed by QoSMOS aims to achieve significant impact, both in terms of business gain through new service opportunities that will arise with increased exploitation of hitherto underused spectrum, but also in terms of technology development and standardisation. To be able to make such commitments, QoSMOS defines graspable and measurable outputs from each of the workpackages.
