Abstract:
Indoor infrared wireless communications can offer in certain applications a valuable alternative to wireless radio. Its main advantages being: low cost, medical safety and unlicensed spectral band. The most suitable infrared band seems to be 1550nm because of the low noise and optical safety, even if sensible receptors at this wavelength are still hard to find at the edge of current technology. In this paper we show an experimental set-up that allows us estimate the impulse response function at the 1550nm wavelength for indoor transmissions using a reduced-model of the actual indoor environment.
