The nofio Wireless for Valve Index, marketed as the nofio wireless adapter for Valve Index, is a third-party wireless video accessory that converts a tethered Valve Index PC VR headset into a wireless one. Developed by the Australian startup nofio, the adapter streams the headset's video signal from a gaming PC over Wi-Fi 6E using a proprietary low-latency compression codec, removing the need for the long fiber-optic cable that normally connects the Index to a computer. It was announced on July 11, 2022, funded through a Kickstarter campaign launched in August 2022, and after repeated delays its companion SteamVR driver was released on Steam on February 9, 2024. The adapter was priced at $399.99 for Kickstarter backers and pre-order customers and sold at retail for $449.

The system is sold as a non-destructive, removable upgrade: a transmitter unit connects to the PC, and a lightweight receiver attaches to the Valve Index headband and feeds video into the headset through a short OCuLink cable. nofio advertised "less than 5 milliseconds" of added wireless video latency, a lossless-quality image, and a supported play area of up to 5 by 5 meters. The product attracted strong early interest but a difficult delivery history, and its Steam driver page has carried a "Mostly Negative" user review rating.

Background

nofio is a startup based in Brisbane, Australia. The company set out to solve a long-standing limitation of the Valve Index: unlike standalone headsets such as the Meta Quest 3, the Index is a PC-powered headset that must be physically tethered to a computer by a thick combined power and fiber-optic display cable. That cable can twist around the user during room-scale play and limits how far a player can move from the PC. While first-party wireless solutions existed for headsets like the HTC Vive (via the official Vive Wireless Adapter), Valve never released an equivalent accessory for the Index, leaving a gap that nofio aimed to fill.

The team announced the project on July 11, 2022, stating it had been developing the underlying wireless technology for some time and was turning to crowdfunding to pay for tooling and components for mass production. Beyond the Index adapter, nofio has signalled broader ambitions in low-latency wireless video, later promoting a wider product line under the name AROS.

Development and funding

After the July 2022 announcement, nofio launched its Kickstarter campaign in August 2022. The project was funded quickly: it raised close to $370,000 in its first 24 hours from roughly 900 backers and went on to collect on the order of $570,000 (about $845,000 AUD) from more than 1,300 backers by the time the campaign closed, well beyond its funding goal. The campaign sold out of its initial allocation and reopened pre-orders before ending.

Like many hardware crowdfunding projects, nofio slipped well past its original schedule. The first units were initially expected to ship in the first quarter of 2023, with an early production run planned for around April 2023. A second wave of pre-orders opened on August 22, 2023, with shipments then targeted for late 2023. In practice, deliveries continued to slip, and units only began reaching customers in volume well into 2024 and 2025, drawing criticism over delays and communication on community forums.

The table below summarises the key milestones.

Date	Milestone
July 11, 2022	Project announced
August 2022	Kickstarter campaign launched; funded in first day
Q1 2023 (planned)	Original target ship window
August 22, 2023	Second pre-order wave opened at $399.99
February 9, 2024	SteamVR driver released on Steam

How it works

The nofio adapter is built around two pieces of hardware: a transmitter that stays with the PC and a receiver (head unit) that mounts on the Valve Index. The transmitter connects to the computer through DisplayPort 1.4 for video, plus USB and external power. It captures and compresses the headset's video feed without, according to nofio, placing meaningful additional load on the PC's GPU. The compressed video is then sent wirelessly over Wi-Fi 6E to the receiver on the headset, which is linked to the Index's display input by a short OCuLink cable.

On the software side the adapter integrates with SteamVR and is driven by a small USB driver distributed through Steam; nofio describes the processing as performed onboard the hardware rather than on the host PC. The Steam listing credits the streaming pipeline to IMRnext's network-aware codec, which uses adaptive compression and subframe streaming to balance image quality against latency over a fluctuating wireless link. nofio stresses that the conversion is non-destructive and removable: the receiver clips onto the existing Index headband and can be taken off to return the headset to its normal wired configuration.

Specifications and features

nofio's headline claim is "less than 5 milliseconds" of added wireless video latency, which the company described at announcement as among the lowest for wireless PC VR video, paired with a lossless-quality image produced by its compression algorithm. The advertised supported play area is up to 5 by 5 meters (about 15 by 15 feet); Road to VR noted the company demonstrated the system in a larger 5 by 10 meter space, and direct line of sight between transmitter and receiver is not strictly required, though keeping both in the same room is recommended.

Power comes from a swappable battery pack rated at roughly 2.5 hours of use, with hot-swapping so a depleted battery can be exchanged without ending the session. Users can also run the receiver from a standard USB-C power bank to extend play time. nofio sold spare batteries and a body strap (to carry the battery) as separate accessories. On the PC side, the Steam driver lists Windows 10 with a 64-bit processor and 4 GB of RAM as minimum requirements (8 GB recommended), in addition to an existing Valve Index headset; Linux support was described as planned.

Reception

The adapter generated considerable enthusiasm at launch, reflected in its rapid first-day Kickstarter funding, because it addressed a feature the Valve Index community had wanted for years and that Valve itself never shipped. Coverage from outlets including Road to VR and MIXED framed it as a promising attempt to bring low-latency wireless to a high-end PC VR headset using Wi-Fi 6E rather than the older WiGig approach used by earlier wireless adapters.

Sentiment cooled as the project ran long. The companion software on Steam has held a "Mostly Negative" rating, with about 35 percent of 124 user reviews positive, and buyers raised concerns on community channels about shipping delays, availability and long-term support. The mixed outcome illustrates the common gap between an appealing hardware concept and the difficulty of delivering, polishing and supporting a niche VR accessory at scale.
