Cyber security of long-range wide-area network (part I)

Long-Range (LoRa) wireless Wide Area Network is increasingly gaining attention in the world of Internet of Things. One such commercial off-the-shelf technology from Semtech is called LoRaWAN. Its wireless broadcasting nature has incurred many cyber security concerns. One such concern is the possibil...
