>WIRELESS AND WIRED MOUSES ARE BOTH GATED BY BUS FRAMES, THEY HAVE AN EQUAL AMOUNT OF LATENCY, LOSSLESS LITTERALT DOE
Both wired and wireless mice are constrained by USB polling intervals (bus frames), but they differ in additional latency sources.
Wired mouse:
– Latency limited primarily by USB polling rate (commonly 1000 Hz 1 ms frame).
– Transmission is electrical and deterministic; no packet retransmission or RF interference.
– Typical total input latency ≈ 1–2 ms (sensor + MCU + USB bus).
Wireless mouse:
– Same USB bus frame limit when using a dongle, but adds RF encoding, transmission, reception, and potential packet validation.
– Modern high-end wireless protocols (e.g., Logitech Lightspeed, Razer HyperSpeed) minimize this overhead to ≈ 0.2–0.5 ms, functionally matching wired latency.
– Bluetooth introduces far higher latency (typically 8–15 ms).
Conclusion:
Both are bus-gated, but not equal in total latency. Wired is strictly deterministic; wireless can approach equivalence through proprietary low-latency RF protocols, but not identical in physical path or error behavior.
