M-Ary Aggregate Spread Pulse Modulation for Robust and Scalable Low-Power Wireless Networks

In this paper we present an overview of the M-ary Aggregate Spread Pulse Modulation (M-ASPM), and provide assessment its suitability advantages for use in low-power wide-area networks (LPWANs). Notably, M-ASPM combines high energy-per-bit efficiency, robustness, resistance to interference, a number other favorable technical characteristics, with spread-spectrum ability maintain network capacity while extending range. We quantify impact mutual interference multiple transmitters demonstrate how such capacity-preserving range extension can be achieved numerous desired areal distributions uplink nodes. Throughout paper, LoRa is used benchmark comparison quantification various features. particular, show that, sharing many essential properties LoRa, provides far more effective extension. When same manner as serve appealing alternative. addition, being different LPWAN solutions, designed concurrently operate spectral band geographical area, cooperatively complementing each other’s coverage.
