A consumer transceiver for long-range IoT communications in emergency environments

As an emerging technology, IoT enables a machine-to-machine connectivity without a network infrastructure. Therefore, IoT is strongly considered a technology for communications in emergency environments. Especially, a WiFi protocol is under standardization as IEEE802.11ah for IoT-based long-range communications. However, the service range is not enough to cover a communication area in emergency situations. This paper addresses a consumer transceiver for long range communications of IoT in emergency environments. The transceiver is based on IEEE802.11ah WiFi protocol which is under standardization for low-cost and low-power services. In this paper, a novel architecture for the transceiver is proposed in order to increase the service range of IEEE802.11ah, which is necessary for the long-range IoT communication of emergency messages in emergency situations. Experimental results show that the presented architecture is suitable for the long-range IoT communication of emergency alert messages.
