Immersive Parallel Reality Virtual Ride Experience Service

Motion-sensing-based immersive parallel reality experience service in outdoor amusement rides (Atlantis) (Using private 5G in the 28GHz band, the company enables real-time, large-scale video and motion data transmission on rides, which is not possible with existing Wi-Fi, providing customers with the same immersive and experiential services as in the field).

<Lotte World's Private 5G network and application>

Lotte World provides a virtual ride experience service using a private 5G network and motion sensing technology (a screen/monitor in the experience center displays a forward view of the actual Atlantis, and the chair the visitor is sitting in moves in three dimensions according to the actual driving situation of Atlantis).

Since it is not an actual ride, the elderly and infirm who could not ride the actual ride can ride, and children can ride without height restrictions.

① Atlantis, a ride at Lotte World, is equipped with a 5G 28GHz transmission module with built-in camera and motion sensor.

② The transmission module sends video and motion data to the motion simulator through a private 5G network.

③ Visitors seated in the motion simulator can virtually experience the realistic attraction.

Data transmitted over a high-capacity/low-latency private 5G network

Uplink: High-capacity video (4K: 40Mbps uplink, 8K: 200Mbps uplink) and motion data (6DOF) from the 28GHz 5G transmission module (including camera and motion sensor) mounted on Atlantis is transmitted to the motion simulator in the virtual experience center via a private 5G network.

  Private 5G Network

  Architecture

 Why did Lotte World choose a private 5G network?
[Not Wi-Fi] It is difficult to send real-time, high-capacity video (4K camera: 40Mbps uplink, 8K camera: 200Mbps) while flying at 72Kmph over Wi-Fi. Lotte World achieved stable video transmission by constructing a 28GHz private 5G network with high capacity and low latency characteristics.

Private 5G network deployment model: 5G core control plane sharing

The 5G core data planes (RU, DU, CU, and UPF) are erected within Lotte World, whereas the 5G core control plane is placed in the cloud outside Lotte World.

Video and motion data from rides are delivered to virtual experience centers at Lotte World via UPF, and traffic does not leave the park.

In the future, when Lotte World expands to additional sites (Lotte World Busan, Lotte World Water Park in Gimhae, Gyeongnam, and so on), each site will share the 5G core control plane in the cloud, lowering building expenses.

Immersive Multilateral Collaborative Military Training System Powered by XR HMDs and Private 5G

Military (combat) training based on realistic virtual augmented reality using 28 GHz at Daedeok University's Military Training Experience Center: Previously, military training has been conducted using single-user XR simulators due to the limitations of existing wired and wireless communication. Daedeok University uses private 5G and XR HMDs to conduct military training with multiple people collaborating simultaneously through multilateral high-speed wireless connections to enhance realism and increase the effectiveness of training.  Not only XR HMD (Head Mounted Display) but also various real equipment will be connected to the communication network and utilized for equipment.

< XR-based military training over Private 5G network> 

Application-level requirements
With 20 users simultaneously using HMDs for XR, the system must support extremely high downlink traffic and minimize data latency as the HMDs and the actual equipment must interactively recognize each other's actions.

• Ultra-fast downlink streaming video data
• Ultra-low latency data transfer
• Military data security

Solution: Private 5G

• Uses high-bandwidth 28Hz spectrum for ultra-fast uplink/downlink traffic handling
• 4.7 GHz + 28 GHz New Radio Dual Connectivity (NRDC) technology for wireless network reliability
• URLLC technology and wide bandwidth 28 GHz data transmission for ultra-low latency data support
• Fully independent closed network for security 

How Private 5G Works

Highest downlink speed: 600 MHz bandwidth in the 28 GHz band enables downlink high-definition XR for multiple users

Ultra-low latency: With RTT of 3-4ms, the screen of the HMD is reflected in real time according to movement, significantly reducing dizziness and headaches, and equipment operation data is also transmitted in real time, enabling realistic training.

Security: In-house network ensures data confidentiality
