The work is never completely finished. That's what we can learn from the Valve Index VR helmet launch party. A wireless system is under study at Valve.
Indeed, during the Index VR headset launch party Valve CEO Gabe Newell stated that the company is “looking into several methods” for making the headset untethered.
Valve worked with HTC to ship the first room scale VR system in 2016, the Vive. In 2018, HTC released a $300 wireless adapter for the Vive, but there’s no indication Valve had any involvement in this project, with HTC citing a partnership with Intel in making it possible.
In early 2016, Valve made a significant investement in wireless VR technology startup Nitero. Nitero designed custom chips to deliver better performance and lower cost than other 60 GHz solutions.
It is clear that Valve is now continuing its efforts that involve Nitero.
Other elements suggest progress in this area, particularly in terms of hiring. However, the road ahead still seems long to make the Valve index totally wireless and released from its cord.
