5G ‘Robocop’ A Reality For SK Telecom
A robot traffic officer, dubbed ‘Robocop’, was the highlight of SK Telecom’s 5G demonstrations at this week’s World IT Show in Seoul.
The demo used In Band Full Duplex (IBFD), which enables ‘simultaneous in-band uplink and downlink communication by cancelling signal interference in real time, to enhance spectral efficiency’.
Current networks cannot transmit and receive signals at the same time on the same channel, leaving mobile operators having to choose between FDD or TDD to allow communication between handsets and base stations.
“SK Telecom’s wirelessly controlled traffic robot is the perfect metaphor for Full Duplex’s role in alleviating wireless traffic jams”
Kumu Networks, a wireless transmission and signal processing technology provider, was a partner in the demonstration and the CEO, David Cutrer, was keen to praise the technology and celebrate the opportunity to work with one of South Korea’s major operators.
‘SK Telecom’s wirelessly controlled traffic robot is the perfect metaphor for Full Duplex’s role in alleviating wireless traffic jams,’ he said. ‘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.’
Labelled a ‘Robocop’, the officer was tasked with traffic management. The robot includes a camera, microphone and multiple sensors, and apparently mirrors human movement without latency and transmits and receives multimedia data to and from the control centre in real time.
It is worth pointing out though, that Alex Jinsung Choi, CTO of SK Telecom did explicitly refer to IBFD as a ‘pre-5G technology’, suggesting it was not 5G as such. Business Korea is reporting that the company also exhibited Millimetre-wave and GiGA path at the event.
“a Memorandum of Understanding with German electronics group Rohde&Schwarz “
The operator has also announced the signing of a Memorandum of Understanding with German electronics group Rohde&Schwarz on Friday, with whom they will measure and analyse radio propagation characteristics of 6GHz or higher frequency bands and jointly set up a 5G test bed for a new interface to support efficient transmission of data in those bands.
