The Era of Holographic Video with 6G: Need for Joint Network Among Telecom Companies

Amid fierce competition for frequency allocation in the sixth generation of mobile communication (6G), experts emphasize the need to secure frequency channel bandwidth capable of delivering ultra-fast services rather than merely focusing on total frequency demand.

On October 20, the Korean Society of Broadcasting and Telecommunications (KSPS) held a policy forum in Jung-gu, Seoul, titled 'Infrastructure Development for Securing National Competitiveness in 6G.'

Jeong Woo-ki, a former professor at Cheonggang College of Cultural Industries, presented on 'Frequency Policy for 6G Mobile Communication Services.' He stated, "To implement ultra-high-speed immersive video services such as 3D images and holograms in the 6G era, it is essential to secure sufficient frequency bandwidth."

Ultra-high-speed immersive video services require substantial data transmission speeds, ranging from hundreds of Mbps to several Gbps. This is up to ten times faster than current 5G services. In this scenario, each operator would need to secure a bandwidth of at least 500 MHz to 1 GHz. However, considering the current frequency situation, it is challenging for individual operators to achieve this level of bandwidth.

Therefore, Professor Jeong emphasized the need for the three major telecom companies to jointly establish a network in the 7-8 GHz frequency range, which is a candidate band for 6G. This approach could ensure sufficient speed while reducing construction and operational costs.

In countries like China and Japan, joint networks have been operational since the 5G era. In densely populated areas such as the metropolitan region, separate networks are established, while less populated areas utilize joint networks.

Additionally, Professor Jeong highlighted the necessity for proactive measures regarding 6G frequency as international discussions on frequency allocation continue. At the World Radiocommunication Conference 2027 (WRC-27), candidate bands such as 4.4-4.8 GHz, 7.125-8.4 GHz, and 14.8-15.35 GHz will be discussed for potential use in International Mobile Telecommunications (IMT).
