Nano wireless communications aim at allowing nanomachines to communicate using either electromagnetic waves or molecular and chemical substances. Although using
electromagnetic waves is attractive, existing wireless technologies must be adopted to
the nanoscale environment due to requirements on device size, energy efficiency, and
the frequency bands that may be used for nanoscale communication. At this seminar
we first review some of the recent advances in electromagnetic wave based nanocommunications.
Next, we discuss frequency and distance dependent channel models that are applicable in
in-body nanocommunication scenarios. Specifically, we present a new channel model based on a multi-layered stack of human tissues representing the skin and modeling the attenuation of electromagnetic signals passing in and out of the body. Finally, we discuss the applicability of physical layer procedures suitable for nanomachines. We conclude by
pointing at some of the challenges that must be overcome before nano machines can
connect to devices either inside or outside the body.
