A Panorama of Music and Light: Sangah Noona Joins RIMA for an Ultra-Low-Latency 5G Concert Between Washington and Uiwang

On Saturday, November 2, 2024, a special concert was held in Uiwang-si, Gyeonggi-do, Korea. Through the RIMA AIoT Concert Zone featuring Emotionwave's advanced technology, this performance connected jazz pianist Sangah Noona from Washington D.C., USA, and Korean audiences in real time, offering an innovative experience that combined technology and emotion beyond a simple remote concert.

The performance began at 2 PM Korea Standard Time (KST), which corresponds to 10 PM EST on Friday, November 1. The two cities, Washington and Uiwang, with different dates and times, were connected onto a single musical stage through 5G ultra-low latency technology. This performance, transcending the limitations of time and space, showed new possibilities and received high expectations from music fans worldwide.

A Moving Performance Transcending Time and Space

Sangah Noona, located in Washington D.C., began her performance from her studio. The performance data was transmitted to the venue in Uiwang, Korea, in real time within an ultra-low latency environment, allowing the audience to feel a vividness and immersion as if the performer were in the same space.

In particular, the highlight of this performance was the rendition of **Kim Kwang-jin's 'Letter'** reinterpreted softly and emotionally in a jazz version. This song perfectly harmonized with Korea's autumn scenery, delivering emotion to the audience. The audience enjoyed a special moment where music and nature blended while listening to Sangah Noona's performance amidst the colorful autumn foliage of Korea. In addition, various genres were showcased, crossing the boundaries of jazz, rock, and KPOP, with songs such as **Autumn Leaves** and **Don’t Stop Me Now** being performed.

RIMA AIoT Architecture: The Perfect Fusion of Technology and Music

The core technology that made this performance possible is the RIMA AIoT Architecture. RIMA is an advanced system focused on ensuring precise synchronization and stability even in ultra-low latency environments, surpassing existing remote performance technologies. This architecture consists of the following key components:

1. Music Transcription AI: Real-time audio source interpretation and score generation
