Abstract

Internet of Things (IoT) is a new revolution of the Internet. It can be said as the expansion of internet services. IoT is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identi-fiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IOT finds applications in almost every areas. As an emerging technology, IoT enables a machine-to-machine connectivity without a network infrastructure. Therefore, IoT is strongly cons-idered as a technology for communications in emergency environments. Especially, a WiFi protocol is under standardization as IEE-E802.11ah for IoT-based long-range communications. However, the service range is not enough to cover a communication area in emergency situations. This paper is a study of IoT ,its architecture and also addresses a consumer transceiver for long range commu-nications 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 eme-rgency messages in emergency situations..
