NI Successfully Demonstrates Real-Time OTA Prototype for 28GHz Verizon 5G
Published2017.04.06 09:36Application of real-time code modifiable at base stations and user equipment
National Instruments (NI) publicly demonstrated a real-time Over-the-Air (OTA) prototype in the 28GHz band based on Verizon's 5G specifications at the IEEE Wireless Communications and Networking Conference (WCNC) held in San Francisco, USA.
This system utilizes hybrid beamforming and independent subframes to use OFDM with eight component carriers in a 2x2 downlink MU-MIMO setup, achieving a throughput of up to 5 Gb per second and scalable to over 20 Gb per second with eight MIMO streams.
The developers developed this prototype using NI's mmWave transceiver system, a new version of the RF mmWave head operating at 28 GHz, and a phased array antenna developed by Anokiwave and Ball Aerospace.
28GHz is a major frequency band designated by Verizon and its partners for distribution in the United States. This prototype system was written entirely in LabVIEW system design software, and modifiable real-time code was applied to both the base station and user equipment (UE or CPE).
James Kimery, Director of RF Research and SDR Marketing at NI, said, “This prototype demonstrates the powerful performance of the NI platform. With this platform combining hardware and software, researchers can now rapidly prototype new wireless standards and obtain results faster. Additionally, by prototyping and testing based on Verizon 5G specifications, they can immediately deploy 5G NR (New Radio) as soon as the standard is established.”

KT Successfully Makes Hologram 5G Call Between Gwanghwamun and New Jersey
KT announced on the 3rd the results of 5G cooperation with US telecommunications company Verizon and stated that the two companies would continue cooperation in 5G services. At the meeting, the two companies successfully demonstrated hologram video calls between Gwanghwamun and New Jersey through global interoperability of 5G networks, showcasing the achievements of 5G cooperation and presenting a new paradigm for 5G business models both internally and externally. This was accomplished through continuous joint cooperation between KT and Verizon in the 5G sector since last year. The two companies have been jointly establishing 5G radio access technology standards that define interoperability between terminals and base stations, including frequency and transmission methods, since February of last year. They plan to complete the hardware standards specification shortly and will discuss specifications in the software field.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK텔레콤이 3월 21일 서울 광화문 일대에서 열린 대형 K-팝 공연에 AI 기반 네트워크 운영 시스템을 처음 적용해 통신 품질을 관리했다고 밝혔다. 공연 전후 3시간 동안 모바일 데이터 사용량은 12.15TB로 직전 주말 같은 시간대보다 약 2배 늘었다. SK텔레콤은 AI 시스템 ‘A-One’을 활용해 5분 단위, 50m 단위로 트래픽을 감시하며 과부하 가능성에 대응했고, 임시 통신 시설과 현장 인력 운영도 병행했다. 밀집 행사와 외국인 이용 수요가 동시에 늘어나는 환경에서 AI 기반 자율 네트워크 운영의 현장 적용 가능성을 확인한 사례로 해석된다.
