Résumé: One of the major challenges facing the fifth generation of mobile telephony is the need to connect tens of billions of objects while also integrating the increased traffic on radio access networks that is anticipated in the near future. Excellent solutions well-suited to relatively low throughput communications and not-too-high connected object densities currently exist, such as the LTE-M, NB-IoT, Sigfox and LoRA standards. However, if the massive deployment of the Internet of Things (Massive IoT) with densities higher than one million high throughput connected objects per km² continue to accelerate, these current solutions could reach their limits and potentially trigger a sharp increase in radio interference levels, meaning data packets may not be properly decoded and video quality will be affected. The typical case will be connected 4K cameras that will sporadically generate a high transmission rate. In this article we try to define the main constraints of a general waveform for the IoT and to analyse the main blocking points for which innovative solutions must be proposed in the future. Issues related to non-orthogonal access and unsynchronized random transmissions are particularly important in the field of IoT as well as the issue of the energy efficiency of the amplification chain.
