    SKT, Ericsson, BMW achieve 3.6Gbps for 5G connected car trial

    SK Telecom achieved what it says is the world’s fastest 5G speed for a connected car during a demonstration conducted with Ericsson and BMW Korea.

    SKT said the trio has successfully tested its pilot 5G network on a connected car running at 170 kilometers per hour, reaching a 3.6Gbps transmission speed over the 28-GHz band.

    The demo was conducted at the German car maker’s driving center in Yeongjong Island, Incheon, where the trio first successfully tested its pilot 5G network for multi-vehicular communications last November.

    SK Telecom said with 5G avoiding obstacles is difficult at high speeds, but the operator achieved this through the application of advanced beamforming and beamtracking technologies.

    “Connected car is regarded as the barometer for 5G as it can only be realized through the combination of all 5G technologies. As ultra-high speed and ultra-low latency are prerequisites for realizing autonomous driving and immersive media services, the 3.6Gpbs transmission speed we successfully demonstrated today not only brings us a step closer to realizing autonomous driving, but will also have a great impact on a broader range of industries,” SK Telecom said in a statement.

    The demo significantly enhances the stability of connected car services by improving image recognition and V2X (Vehicle to Everything Communication) technologies, the operator added.

    “That is, a vehicle will be able to communicate, in real time, with other vehicles, traffic lights and surveillance cameras to understand and respond to unexpected situations and obstacles… in a much shorter time.”

  • SKT, Ericsson and Qualcomm collaborate on 5G NR trails

    SKT, Ericsson and Qualcomm collaborate on 5G NR trails

    SK Telecom, Ericsson and Qualcomm have announced plans to conduct interoperability testing and over-the-air field trials based on 5G New Radio (NR) standards currently under development by the 3GPP.

    In a statement, the companies said the trials will drive the mobile ecosystem toward rapid validation and commercialization of 5G NR technologies at scale.

    The interoperability testing and trials will launch in Korea starting in the second half of 2017.

    “As 5G rapidly gains momentum, a globally agreed and unified standard becomes imperative to achieve early commercialization of 5G and build an efficient ecosystem around it,” said Alex Jinsung Choi, EVP, chief technology officer at SK Telecom.

    “As 3GPP NR is a global 5G standard, we are delighted to announce early 3GPP NR trials with leading 5G players, Ericsson and Qualcomm, with which we have made remarkable world’s first footprints in the past with previous generations of groundbreaking mobile technologies.”

    During the trails, SK Telecom, Ericsson and Qualcomm will showcase new 5G NR technologies which utilize wide bandwidths available at higher frequencies to increase network capacity and achieve multi-gigabit per second data rates.

    The proliferation of 5G NR technology can make it more cost-effective and easier for multi-gigabit internet service to reach more homes and businesses.

    These technologies will be critical to meeting the increasing consumer connectivity requirements for emerging consumer mobile broadband experiences such as virtual reality, augmented reality and connected cloud services.

    The trials will employ 3GPP 5G NR Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques to deliver sustained mobile broadband communications at higher frequency bands, including non-line-of-sight (NLOS) environments and device mobility.

    It will also make use of scalable OFDM-based waveforms and a new flexible framework design which are also part of the 5G NR specifications.

    The trials will also provide valuable insight into the unique challenges of integrating 5G NR technologies into mobile networks and devices. This will enable timely commercial network launches based on 3GPP Rel-15 standard compliant 5G NR infrastructure and devices.

    “The roadmap of 5G technologies is incredibly complex, and trials based on the global 3GPP 5G standard, such as this, are critical to continuing our long history of leadership integrating advanced wireless technologies in form-factor accurate devices to ensure timely deployment of 5G networks,” said Matt Grob, executive vice president and chief technology officer, Qualcomm Technologies.

  • SKT, Nokia develop portable PS-LTE network

    SKT, Nokia develop portable PS-LTE network

    SK Telecom and Nokia have completed the development the first all-in one portable public safety LTE system for emergency first-responders.

    The system is compact enough to fit in a backpack, and comes with all the elements required for mobile communications, from a base station, switching system including an evolved packet core to push-to-talk technologies.

    It can be used to create an independent LTE communications network in the field for use by public safety and emergency services workers. The resulting network can be set up in less than three minutes, has a 5km coverage and can accommodate up to 400 users.

    SK Telecom and Nokia achieved the breakthrough of alleviating the need for PS-LTE systems to connect to a backhaul network by applying NFV technologies to the core networking elements. This has allowed the partners to fit the technology into a small rectangular-shaped server.

    The system can also support other communications services including group messaging for public service agencies.

    SK Telecom has announced it plans to trial the system within the year, and use the technology to expand the national disaster safety wireless network as well as its LTE-Maritime project in 2017.

    “The portable all-in-one PS-LTE system is a ground-breaking solution that enables communication among first responders by setting up an independent LTE network when regular communication networks are disrupted by disasters,” SK Telecom executive vice president and head of infrastructure Lee Jong-bong said.

    “SK Telecom will not only utilize the innovative system to build disaster safety wireless networks in Korea, but also plans to share its expertise and know-how with many other countries around the world.”
