LoRaWAN IoT networks use an unlicensed, public spectrum called the Industrial Scientific and Medical (ISM) frequency band. To prevent degradation of other industrial communications already using the ISM band, the network will support the Listen Before Talk (LBT) function. As well as a new service model, the Internet of Small Things (IoST), that will also be introduced as a key facilitator for more business opportunities utilising Low Power Wide Area.
In fact, South Korea’s largest telecom, KT (formerly Korea Telecom), will be investing $128.7 million in establishing an NB-IoT network using LTE-M to support the network in Korea. It will also offer about 100,000 IoST sensor modules for developers to spur the IoST business ecosystem.“We will provide 100,000 IoST telecom modules for free and offer the service without charge this year. We will pour 150 billion won into this sector, which is an aggressive investment”, KT’s IoT business division senior vice president Kim June-keun said
IoST can also be applicable to every industrial sector, from manufacturing to agriculture, he said. Sensors attached to manufacturing lines will enable factory automation and boost industrial safety. “We will provide modules almost limitlessly to developers to fulfil diverse business needs that we cannot yet imagine”, he said.
Be it for smart city networks or otherwise, South Korea is setting standards for IoT deployment worldwide. The new LoRaWAN network should further develop the country as a centre for smart cities innovation by providing a cheap way to connect physical urban infrastructure to the internet.
