In 2017, the VR market didn’t show much optimism. Analysts expected that wireless technology would become a key driver for growth in 2018. However, after two years of development, the real breakthrough might have to wait until 2019. The year 2017 ended with many uncertainties and challenges for the virtual reality headset market. Despite this, there was hope that 2018 would bring significant progress, especially in moving toward wireless solutions. This shift is considered a crucial step in making VR more accessible and user-friendly.
Many manufacturers announced plans to release wireless accessories for VR headsets during 2017, but only a few products were actually launched. The TPCast solution for HTC and Oculus Rift was one of the few available options. However, it doesn’t use WiGig technology, which means it’s a proprietary system not compatible with other devices. While this is a temporary fix given the limited number of VR headsets on the market, long-term success will depend on cross-platform compatibility.
VR didn’t have a strong year in 2017, so companies are now relying on wireless technology to create better conditions for future growth. Several companies, including Chaowei, Intel, Peraso, and Qualcomm, are working on WiGig-based chip solutions. However, these chips aren’t yet available. Originally, they were expected to hit the market in late 2017, but the launch has been pushed to 2018. By the second half of 2018, we can expect a surge in wireless VR products, which would be a major milestone for the industry by removing one of the biggest barriers to adoption.
Although many companies haven’t revealed specific timelines for their wireless chip launches, more details are expected to be announced at CES 2018 in Las Vegas. Wireless technology definitely helps solve some of the challenges in VR development, but it still faces technical hurdles. For instance, improving display resolution remains a challenge. Additionally, current 60 GHz and WiGig solutions make wireless VR more complex than desired.
The 802.11AD standard, which supports high-speed wireless transmission, lacks sufficient bandwidth and has higher latency, prompting the industry to wait for the upcoming 802.11AY standard. This new standard offers peak data rates between 20 to 40 Gbit/s within the same 60 GHz spectrum—four times faster than 802.11AD and WiGig. This improvement is particularly beneficial for streaming 4K video content.
According to the IEEE timeline, the draft version of the 802.11AY standard was completed in November 2017, and final approval is expected in 2019. As a result, the full commercialization of wireless VR may take two more years. This delay presents one of the biggest challenges for the VR industry as it works toward a more seamless and immersive experience.
