VR Wireless Streaming Bandwidth Checker

Why wireless VR is the hungriest stream in your home

A 4K Netflix movie sips about 15 Mbps. A wireless VR headset can demand more than ten times that — and it is far less forgiving about delay. When you stream PC games to a VR headset over Wi-Fi (with Meta Air Link, Virtual Desktop, or Steam Link), the PC renders a fresh frame for each eye, encodes it, fires it across your network, and the headset decodes and displays it — all in well under 40 milliseconds. Miss that window and the world stutters, which in VR means nausea, not just buffering. A Quest 3 renders 2160 × 2160 pixels per eye at 90 frames a second: that is over 20,000 Mbps of raw image data before compression. Your Wi-Fi never sees the raw stream, but it still has to carry 150–450 Mbps of encoded video with almost no delay.

How the calculator estimates your bitrate

The calculator starts with the physics: total pixels (two eyes × per-eye resolution × 24 bits per pixel × refresh rate) gives the uncompressed data rate. Then it divides by your codec's real-world compression factor — roughly 60× for H.264, 80× for H.265/HEVC, and 100× for AV1. The result is the recommended bitrate: the speed your Wi-Fi must sustain, not just hit once. Latency is estimated as an 8 ms tracking-and-display pipeline plus your Wi-Fi standard's typical delay (about 15 ms on Wi-Fi 5, 10 ms on Wi-Fi 6, 7 ms on Wi-Fi 6E/7) plus the codec's encode overhead. If the stream uses under 60% of your measured Wi-Fi speed, there is headroom; 60–85% is tight; above 85% your network cannot sustain it.

Worked example: Quest 3 over Wi-Fi 6

Take a Quest 3 at 2160 × 2160 per eye, 90 Hz, using AV1 over Wi-Fi 6, with a measured Wi-Fi speed of 500 Mbps. Raw data: 2 × 4,665,600 pixels × 24 bits × 90 ÷ 1,000,000 ≈ 20,155.4 Mbps. AV1 compresses that about 100×, so the recommended bitrate is about 201.6 Mbps — roughly 40.3% of your 500 Mbps, which means plenty of headroom. Estimated latency: 8 ms pipeline + 10 ms Wi-Fi 6 + 18 ms AV1 = 36 ms, which is playable: fine for casual games, slightly noticeable in competitive ones.

Tips for a smoother wireless stream

Put your headset and PC on a dedicated 5 GHz or 6 GHz band, and keep the router in the same room as you play. Run an Ethernet cable from your PC to the router — the wireless hop should only be the headset side. If scenes stutter, drop the refresh rate to 72 Hz or switch to a more efficient codec like AV1. And remember: your internet plan speed is irrelevant here. The VR stream travels only your local network between the PC and the headset, so upgrade the router, not the plan.
