This paper describes the measurements and the analysis of the impact of radio wave polarisation on off-body communications in Body Area Networks in indoor environments. Measurements on polarisation impact are briefly described. Five investigated scenarios with different body postures and different antenna placements are characterised. The difference between the vertical and horizontal components of...
Full wave simulations with realistic models of the human body are a powerful tool to study Body Area Networks. Usually, some simplifications are introduced in simulation models to speed up computation routines, and to save memory resources. This paper analyses the use of truncated voxel models, and discusses the option of using homogeneous or voxel phantoms. The metric used for the assessment is the...
Current 3GPP specifications for LTE include the use of MIMO as a key technology. MIMO can be seen from two different perspectives: if increased data rates are targeted, for a given value of SNR, one gets improved data transmission; however, from an energy efficiency viewpoint, lower values of SNR are needed for the same reference data rate, therefore, allowing the reduction of the transmitted power,...
