Practical Accuracy Limits of Radiation-Aware Magneto-Inductive 3D Localization
Gregor Dumphart, Henry Schulten, Bharat Bhatia +2
The key motivation for the low-frequency magnetic localization approach is that magnetic near-fields are well predictable by a free-space model, which should enable accurate locali…
Inter-Node Distance Estimation from Multipath Delay Differences of Channels to Observer Nodes
Gregor Dumphart, Marc Kuhn, Armin Wittneben +1
We study the estimation of distance d between two wireless nodes by means of their wideband channels to a third node, called observer. The motivating principle is that the channel…
Magneto-Inductive Powering and Uplink of In-Body Microsensors: Feasibility and High-Density Effects
Gregor Dumphart, Bertold Ian Bitachon, Armin Wittneben
This paper studies magnetic induction for wireless powering and the data uplink of microsensors, in particular for future medical in-body applications. We consider an external mass…
