An Introduction to Appropriate Technology

Abstract

In this report, the end user scenarios, test cases and requirements envisioned by the METIS project are mapped to propagation scenarios. Furthermore they are analysed for deriving a new set of requirements relevant for radio channel and propagation modelling. Since none of the existing channel models in the literature satisfies all these requirements, we develop new channel models based on extensive measurement campaigns and analysis complemented by computer simulations. The developed METIS channel models consist of a map-based model, a stochastic model, and a hybrid model derived from both, to provide a flexible and scalable channel modelling framework. In addition, guidelines including practical examples are provided for utilizing the models in simulations.
