SK Telecom is already spearheading innovations in 4G services in Korea. SK Telecom became the world’s first mobile carrier to commercialize 150Mbps LTE-Advanced in June 2013 and 225Mbps LTE-Advanced in June 2014 through Carrier Aggregation (CA). It also commercialized 300Mbps tri-band LTE-A CA. SK Telecom currently has more than 17 million 4G LTE subscribers in the country.
Alex Jinsung Choi, CTO of SK Telecom, said: “We will continue to drive innovations towards the 5G era by seeking and developing enhanced network technologies with our partners.”
SK Telecom in a statement said IBFD from the California-based developer enables simultaneous in-band uplink and downlink communication by cancelling signal interference in real time, significantly enhancing the spectral efficiency.
As the current networks cannot transmit and receive signals at the same time on the same channel, telecom operators have to select either FDD or TDD to enable communication between base stations and handsets.
The Robocop — built with a camera, microphone and multiple sensors — mirrors human movement without latency and transmits/receives multimedia data including video and audio to/from the control center in real time.
