# Experimental work

> What we have measured, what remains a prototype, and what is not yet claimed.

## Qualcomm two-link station and STR work

The WCN7850 station patch remains included in unified 2.1.36 and disabled by default. Earlier experimental tests associated on 5 and 6 GHz and carried traffic on both links. Two links alone do not prove simultaneous RF transmit/receive or throughput improvement. Later signed-image supplicant tests did not establish the same association behavior. Time-aligned RF/firmware evidence remains open.

## FTM ranging

The image includes a bounded, opt-in WCN7850 single-peer 802.11mc helper gated to Pi 5. It uses the measured 5 GHz, 80 MHz request format, a fixed reply buffer, request limits and timeouts. Timing units and antenna delay remain uncalibrated.

This is not general 802.11az, calibrated distance or qualified NanoPi/QCNCM865 ranging. Host tests cover decoding, bounds and radio-ownership cleanup; live ranging on current releases is not yet qualified.

## Relative Qualcomm spectrum

The WCN7850 helper streams 64 relative FFT bins and restores owned radio state on Stop. It has passed a short live test on a Pi 5. It is not a calibrated analyzer or simultaneous dual-band capture from one card.

## Roadmap

The current image includes owner-managed Linux Bluetooth keyboard/mouse/touchpad pairing and saved bonds, plus managed NetAlly sweeps and bounded WiPry acquisition. See the [touch and Bluetooth guide](/guides/touch-console/) and [standalone integrations](/developers/). Broader analyzer qualification, complete RADIUS management and app/web parity remain open.
