In September 2016, Sofia-based startup Quark VR shared an update on one of the most anticipated hardware experiments of the year: a wireless adapter for the HTC Vive. At the time, every consumer Vive was tethered to a PC by a heavy cable bundle — the single biggest complaint about room-scale VR.
Quark VR's approach streamed the video signal over WiFi from the PC to a small transmitter worn by the user, with the team working closely with Valve on the prototype. The company said a working public prototype was expected that fall, and the announcement drew wide coverage across the VR press as one of the first credible attempts to cut the cord on PC VR.
The wireless race that followed — TPCAST, Vive Wireless Adapter, and eventually standalone headsets like the Quest line — proved the demand Quark VR had identified early. Wireless, high-resolution VR is now the default expectation, including for the adult VR platforms we review today.
