SK Telecom, Nokia Networks demonstrate LTE low power communication technology for IoT in Korea

  • First demonstration of LTE low power communication technology for Internet of Things (IoT) devices in Korea
  • Highlights the capabilities of Power Saving Mode in extending the battery life of IoT modems to more than10 years
  • Validates the potential of half-duplex mode as a viable means to increase IoT connectivity efficiency


Seoul, Korea – 17 November 2015


Power management will be a critical element of the future programmable world, where some 50bn devices* will be connected in 2025. SK Telecom and Nokia Networks have taken a concrete step towards this future, showcasing IoT connectivity with Power Saving Mode for the first time in the country. The over-the-air trial was conducted 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. In essence, low power IoT technology streamlines device operation to essential capabilities, and switches to Power Saving Mode when there is no data transmission needed, thus enabling significant reduction in power consumption.

Key advantages of implementing LTE-based low power technology for IoT:

  • 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

Jin-hyo Park, Senior Vice President and Head of Network Technology R&D center, SK Telecom, said: “With this trial, we have successfully 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. In collaboration with Nokia Networks, we will continue to push the boundaries for IoT and pave the path for broader application of services powered by this next-generation technology.”

Andrew Cope, Head of Korea, Nokia Networks, said: “This achievement, a country-first, adds another important dimension to our relationship with SK Telecom as we set the pace for the telecommunications industry in Korea. Moreover, it underlines our focus on setting the platform for the global adoption of LTE as a technology-of-choice for IoT, evolving to NB-LTE for IoT in the future, as we head towards a world where everyone and everything is connected.This marks yet another step forward on Nokia’s goal of bringing NB-LTE to life.”

Did you know?

In Korea, more than 99% of the population is under LTE coverage. The GSMA expects that 63% of the world’s population will have access to LTE by 2020. As such, LTE is the ideal connectivity technology that synergizes efficiency, global scale and reach to deliver the best-in-class service experience to subscribers.
