Cracking open what makes Apple's Low-Latency WiFi so fast
Henri Jäger
39th Chaos Communication Congress (39C3): Power Cycles · Day 2 · Saal One
This talk, presented by Henri Jäger, delves into the intricate mechanisms behind Apple's proprietary **low-latency Wi-Fi** (LLW) technology, which underpins many of the company's "Continuity" features like Sidecar, Universal Control, and iPhone Mirroring. Jäger, a researcher at Open Citus and a student at the Hassop Platner Institute, shares insights derived from his master's thesis, aiming to demystify how Apple achieves such high-performance wireless communication between its devices. The research not only uncovers the technical specifics of LLW but also highlights the broader implications for interoperability and the potential for open-source reimplementations of Apple's tightly integrated ecosystem features.
