SK Telecom and Nokia demo LTE low power technology
17 November 2015 |
SK Telecom and Nokia Networks claim to have demonstrated the first LTE low power communication technology for the internet of things (IoT) in Korea.
The demonstration highlights the capabilities of power saving mode by 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.
“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,” said Jin-hyo Park, SVP and head of network technology R&D centre at SK Telecom.
“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."
The companies conducted the over-the-air trial in a test bed within SK Telecom’s network technology R&D centre, utilising Nokia’s flex multiradio 10 base station and IoT devices provided by GCT semiconductor.
According to the companies, the lower power IoT technology will allow manufacturers to reduce modem complexity and cut costs. In addition, they claim that location-tracking or data-collection devices – with power-saving mode activated – can run for more than a decade without power supply or battery replacement.
