Analyse de la coexistence des technologies à spectre étalé et à bande très étroite dans les bandes ISM

Abstract : The rapid growth in the Internet of Things (IoT) leads currently to an increase in the density of the number of connected objectsbym2. To reduce the energy consumption, these devices should access randomly to the channel which leads to a high probability of collision.Among the various technologies that are used to connect this massive number of devices, we distinguish two emerging technologies based onSpread Spectrum (SS) and Ultra Narrow Band (UNB). The goal of this paper is to analyze the impact of the coexistence of these two technologiesin term of bit error rate (BER) by defining a formal expression for the interfering signals.
