KT, South Korea's second-largest mobile carrier, has with Nokia and Intel demonstrated Internet of Small Things services using NB-IoT technology on a commercialized LTE network.
The telco showed off its "IoT Safety Jacket," an outdoor sports wear made by local Kolon Sports with Intel's NB-IoT module.
The jacket was designed for hikers who become stranded and can't request for help. The sensor will read unusual movements of the wearer and send GPS and conditions to control rooms of authorities, KT said.
Signals are usually hampered in mountainous areas, but NB-IoT, or narrow band IoT, which uses 200kHz bands, allows for small data transmissions to overcome these issues, the telcos said.
KT also showed off "IoT Smart Tent" which uses an infrared sensor to read fires and humans.
The companies will continue to launch new services using the IoT network going forward, they said.
"The latest demonstrations with KT are important achievements in our partnership," said Andrew Cope, head of Korea, Nokia. "We will continue to work with various partners to prove that NB-IoT technology allows for new Internet of Small Things services and increases public safety."
