Seoul, Korea, May 27, 2015 – SK Telecom announced today that, together with Kumu Networks, it will demonstrate a robot traffic officer using In Band Full Duplex (IBFD) technology at the World IT Show 2015 (WIS), to be held in Seoul, Korea from May 27 to 30.

IBFD is being highlighted as one of the key pre-5G technologies as it enables simultaneous in-band uplink and downlink communication by cancelling signal interference in real time, thus significantly enhancing the spectral efficiency.

As the current networks cannot transmit and receive signals at the same time on the same channel, mobile operators have to choose either FDD or TDD to enable communication between base stations and handsets.

At this year’s WIS, SK Telecom and Kumu Networks will showcase a new Robocop tasked with traffic management in the pre-5G network environment applied with the IBFD technology. Built with a camera, microphone and multiple sensors, the Robocop not only mirrors human movement without latency, but also transmits/receives multimedia data – both video and audio – to/from the control center in real time

As the demonstration shows in detail how 5G networks can wirelessly transmit and receive massive amounts of data in a real-time manner, it is expected that 5G, once realized, will enable flawless provision of innovative IoT services.

SK Telecom and Kumu Networks have signed a Memorandum of Understanding for technology cooperation on March 2, 2015 at the Mobile World Congress 2015 held in Barcelona, Spain. Kumu Networks, a California-based developer of wireless transmission and signal processing technology, is the leader in the field of IBFD technology.

“SK Telecom is delighted to demonstrate IBFD, a key pre-5G technology, together with Kumu Networks,”said Alex Jinsung Choi, CTO of SK Telecom.“We will continue to drive innovations towards the 5G era by seeking and developing enhanced network technologies with our partners.”

“SK Telecom’s wirelessly controlled traffic robot is the perfect metaphor for Full Duplex’s role in alleviating wireless traffic jams,” said Kumu Networks CEO David Cutrer. “We are very excited to work with SK Telecom as they trial and deploy cutting edge In Band Full Duplex applications to boost today’s wireless network capacity and pave the way to 5G.”
