Shaping Immersive Realities: Overcoming Network Challenges in Virtual and Augmented Reality

Amidst the rapid advancement of virtual and augmented reality, a crucial challenge emerges: network performance.  VR and AR technologies have the potential to transform industries from gaming to healthcare, but to be successful the networks upon which they rely need to enable the delivery of a seamless experience.

Exploring the critical role of network adaptability is key to enhancing XR’s usability. Real-world networks, upon which XR relies, will always experience variable conditions such as latency and this will influence the experience of the end user.  Understanding the impact of these conditions however, on devices and applications, provides insight to inform the optimal network design for reliability and deployment success.

Key Considerations For Successful XR Network Deployment

Cloud Offloading

Empowers XR by harnessing cloud computing for the data processing for complex immersive environments, significantly reducing the hardware burden on headsets.  Network designs that provide optimal offload balance are essential.

Network Impairments

Variability in network conditions can severely impact the end user. Reliability is critical for real-time experiences.  Understanding these variables is essential in achieving network reliability.

XR Hardware

Innovating towards sleeker, more user-friendly headsets that deliver deeply immersive experiences requires an understanding of the impact that cloud offload can have on the end user.  If the offload balance is wrong the end user will bear the impact.

What Should Be Tested: XR Use Cases

Pre-Deployment Testing
Motion-to-Photon Latency
Post Development Testing

Pre Deployment – Test Real World Scenarios Pre Deployment

Create fully automated test plans, ensuring your device and applications withstand not just ideal, but all network conditions. Create real-world scenarios and impairments from packet loss to jitter and pre-emptively refine your performance, enhancing user experience across the board, and solidifying your reputation from day one.

Emulating Motion-to-Photon Latency: Repeatable & Controllable Test Environments.

When cloud offloading is utilised for processing, networks become at risk of motion-to-photon latency.  If this exceeds 20ms, and the immersion is lost or delayed, this can cause motion sickness for the end user, potentially posing the risk of long-term health effects for frequent users.

Emulate different levels of latency to provide insight into potential cyber sickness triggers caused by variable conditions. Understanding this before deployment, allows for mitigations to be put in place to ensure a smoother and safer XR user experience.

Post Deployment: Optimization, Bug Patches & Solving Live Performance Issues

Accurately replicate the conditions under which user issues occur. This enables precise, step-by-step recreation of real-world scenarios, facilitating swift identification and resolution of any encountered problems, thereby enhancing ongoing performance and user satisfaction.

Don’t Use Your Loyal Customers as Guinea Pigs!

Using network emulation equips you to launch your XR application, device, or network confidently, ensuring smooth user experiences from day one. By emulating real network conditions; latency, jitter, and bandwidth throttling, you can test against a variety of scenarios, including those that cause failures and that impact customer satisfaction. This enables early detection and fixing of network-related issues, enabling network reliability, and enhancing user experience at all times.
