Low-Power Wide-Area Networks (LP-WANs) aim to provide wireless connectivity at extremely low data rates (kbps) over distances of several miles to devices powered by a 10-year battery. Recent years have witnessed several efforts in this space such as LoRa, SIGFOX and NB-IoT. However, today's LP-WANs struggle to cope with the scale of future IoT deployments and the significant signal attenuation posed by urban environments. The WiTech lab group's research has developed new solutions for allowing LP-WANs to scale more efficiently, achieve even longer range in urban settings and save battery life.
