Valve is working on a "SteamVR Link Dongle" to improve the reliability of wireless PC VR.
The dongle, mentioned in SteamVR code, will offer a dedicated point-to-point connection from PC to headset, eliminating network congestion and signal issues.
Existing options like Steam Link app and Air Link rely on home Wi-Fi networks, which can be affected by distance, obstacles, and network congestion.
Valve's dongle may be bundled with the upcoming Deckard headset and could potentially support other standalone VR headsets as well.
