A Wi-Fi access point sounds the channel with an NDP; the client responds with compressed BFI data.

Prompt: A Wi-Fi access point with multiple antennas transmits a Null Data Packet toward a client device. The client device processes the received signal and sends back a compressed Beamforming Feedback Information report to the access point. The two devices face each other with signal waves visibly propagating between them, illustrating the sounding and feedback exchange. Style: Detailed digital illustration blending technical schematic linework with painterly atmospheric rendering, as if a scientific textbook were reimagined by a noir graphic novelist. Colour palette of deep midnight blue, charcoal black, and slate grey as foundations, accented with electric teal, bioluminescent green, and cold amber. Lighting is dramatic and directional, suggesting surveillance or laboratory environments — pools of cold light against deep shadow, with occasional glowing circuit-trace highlights. Compositions favour tight framing with layered depth: foreground technical detail dissolving into abstracted background geometry. Detail level is high but purposeful, prioritising legible structure over decorative complexity. Mood is clinical yet ominous, precise yet unsettling. No text, lettering, captions, logos, watermarks or borders unless it is a technical drawing.
