Will long-range wireless IoT in unlicensed bands cause issues?
Long-range, large scale deployments of IoT networks have high impact on the wireless spectrum. The main technologies for LPWA (low-power, wide area) IoT in licensed spectrum are LTE-M1 (LTE Cat MTC), LTE-M2 (NB-IoT) and (future) 5G IoT. In unlicensed spectrum, LoRaWAN (based on spread spectrum) and SIGFOX (ultra narrowband) are the most …
