Intel has officially announced its withdrawal from the wireless VR market, marking a significant turning point for TPCAST. This decision is seen as a major win for TPCAST, especially as it now collaborates with Huawei to develop a 5G-based wireless VR solution, effectively creating a wide-area network (WAN) version of wireless VR. This new approach is expected to reshape the future of immersive experiences.
Just days after HTC Vive unveiled its all-in-one VR headset, Huawei Wireless Labs (Wireless X Labs) signed a memorandum of understanding with Beijing Transmission Technology Co., Ltd. (TPCAST). The partnership aims to develop cloud-rendered VR solutions leveraging 5G technology, low-latency codecs, and real-time data control protocols. This collaboration highlights the growing trend toward cloud-based VR systems that reduce the need for high-end hardware on the user side.
There are two primary methods for implementing VR. One involves using a smartphone inside a VR headset, commonly referred to as a "smartphone box" or "all-in-one" device. While cost-effective, these systems often suffer from poor visual quality due to the limitations of mobile hardware. The other method involves high-end headsets connected to powerful PCs, offering superior visuals but requiring wired connections and additional investment in computing equipment.
Zhou Zhaohui, CTO of Transmission Technology, explained that their 60G wireless accessories for HTC Vive were initially a compromise—essentially a local area network (LAN) version of wireless VR. However, with the advent of 5G, users can now eliminate the need for a PC altogether. “TPCAST and Huawei are working together to create a 5G-based wireless VR solution,†he said. “This represents a true WAN-level wireless VR experience, where complex image processing is moved to the cloud for real-time rendering.â€
The evolution of wireless VR has been rapid, from early WiFi solutions to the first-generation TPCAST Wireless HD in 2016, followed by WiGig. In just under three years, the industry has made significant strides.
Looking ahead, Zhou Zhaohui believes that “in the future, all PCs may run in the cloud, meaning users only need a headset and nothing else.†This vision aligns with the broader movement toward cloud-based computing and streaming services.
Intel's recent decision to discontinue its wireless VR chips has been interpreted as a sign of retreat from the market. However, Transmission Technology remains confident in its position, noting that Intel’s new chips will not be available until next year. Meanwhile, TPCAST continues to adapt its solutions for leading headsets like Oculus and HTC Vive, while also working on Microsoft-based mixed reality (MR) compatibility.
In 2017, during CES in Las Vegas, an Israeli representative visited TPCAST’s booth and showed interest in its wireless VR solution. Later, it was revealed that this person was part of Intel’s wireless team. Despite Intel’s initial efforts, the company eventually partnered with DisplayLink, introducing a 7ms delay solution that posed a challenge to TPCAST.
However, when Intel announced the discontinuation of key components in September, TPCAST felt relieved. With Intel stepping back, the competition seemed to fade, giving TPCAST a stronger position in the market.
As for the next generation of wireless solutions, the debate between WirelessHD and WiGig continues. While WirelessHD offers a mature protocol, its bandwidth limitations make it unsuitable for higher-resolution displays. WiGig, on the other hand, promises faster speeds and better support for 4K and even 8K content. ABI Research predicts that by 2022, 84% of VR devices will use WiGig technology.
Looking forward, TPCAST plans to embed its modules directly into VR headsets, eliminating the need for external accessories. This shift marks a significant step toward more seamless and integrated wireless VR experiences.
Meanwhile, Microsoft is preparing to launch a new MR solution, which could further expand the possibilities of wireless VR. With companies like Samsung and Fujitsu joining the effort, the market is set for continued innovation.
Overall, the wireless VR landscape is evolving rapidly, with TPCAST at the forefront of this transformation. As 5G and cloud technologies continue to advance, the future of VR looks more promising than ever.
