SK Telecom and Nokia Networks demonstrated LTE low power communication technology for IoT in Korea.

This is the first demonstration of LTE low power communication technology for Internet of Things (IoT) devices in Korea.

The demo highlights the capabilities of power saving mode in extending the battery life of IoT modems to more than 10 years. It also validates the potential of half-duplex mode as a viable means to increase IoT connectivity efficiency.

Seoul, Korea-based SK Telecom and Finland-based Nokia Networks showcased IoT connectivity with Power Saving Mode for the first time in the country. They conducted over-the-air trial in a test bed within SK Telecom’s network technology R&D center, using Nokia’s Flexi Multiradio 10 Base Station and IoT devices provided by GCT Semiconductor.

# LTE-RAN support for upcoming LTE-based modems in half-duplex mode allows manufacturers to reduce modem complexity and cut costs

# Power Saving Mode, a universal functionality in these LTE-based IoT modems, enables extension of battery life to 10 years-plus for autonomous operations

# With Power Saving Mode activated, location-tracking devices, or data-collection devices that monitor water or gas usage, are able to run for more than a decade without power supply or battery replacement

“With this trial, we have verified the capabilities of our IoT technology in resolving challenges posed by power supply and inefficient battery use, which are obstructing the widespread adoption of IoT devices,” said Jin-hyo Park, head of Network Technology R&D center, SK Telecom.
