SK Telecom, South Korea's largest mobile carrier, and Samsung successfully tested a 5G system using 28 GHz millimeter wave technologies last Thursday, bringing the country a step closer to launching super-fast data for a host of new tech, such as VR, holograms, IoT, and driverless cars. The two companies tested the system's millimetre wave transmitter, receiver, and antenna technologies designed to effectively transmit radio signals in the 28GHz band, as well as 3D beamforming tech. It is regarded as a crucial test for 5G to actually work. South Korea was first to roll out LTE, or 4G, telephony for mobile communications. And it is widely acknowledged as a matter of pride that the country will be the first in 5G as well, aiming for February 2018 when it hosts the Pyeonchang Winter Olympics to show off its ICT prowess.
Singtel has begun issuing SIM cards that are compatible with 5G standalone networks, which the telco currently is rolling out in Singapore. Its next-generation mobile network has been deployed for testing in "hundreds" of locations across the island including a couple of indoor sites, though, customers still will need to wait until their handsets are ready to access such networks. Singtel's said Tuesday its new customers or those renewing their service contracts could opt for the new 5G SIM card, if they signed up for the telco's 5G Now add-on service or 5G XO Plus 68 plans and above. The SIM card would be issued for free, with the SG$37.45 However, customers with these SIM cards still would not be able to access services via the 5G standalone network, even if they owned 5G-ready smartphones.
Samsung Electronics and Japanese telco KDDI have succeeded in verifying 5G network slicing technology, the South Korean tech giant said on Wednesday. The test was done in a Tokyo lab that used a RAN intelligent controller with a handset, 5G base station, and 5G standalone core equipment, Samsung said. Each slice is used for different tasks to allow networks to be ultra-fast and have ultra-low latency. The technology will help with services such as autonomous driving, cloud gaming, and industrial Internet of Things applications thanks to low latency and high reliability, Samsung explained. It will also improve connection speeds for virtual reality, augmented reality, and ultra-high resolution video streaming services.
KDDI and Samsung have competed a 5G field trial in a 30,000-person capacity baseball stadium in Japan, the companies announced. The two firms successfully downloaded and streamed a live feed of 4K video on a 5G tablet at Okinawa Cellular Stadium. Samsung's 5G access units with beam-forming technology were installed on a light tower outside the left field fence. A 5G coverage area was created in the direction of the home plate up to the first and third base and tablets were placed on the covered seats to download and stream 4K videos. The successful outcome will lead to new viewing experiences in crowded places like international conferences and music concerts using 5G and ultra-high frequency spectrum, such as the 28GHz used for the trial, the companies said.
