Roaming Aggressiveness
is a configuration setting in a Wi-Fi adapter that determines how eagerly a device searches for and switches to a new wireless access point (AP) when the current signal begins to weaken. It essentially defines the threshold of signal degradation required to trigger a "handoff" between different points in a network. Understanding How it Works
Con:
Can drain laptop batteries faster because the Wi-Fi card is constantly scanning. Stability
- Client-driven vs. network-driven roaming optimization: how to best combine 802.11k/v/r signals and client heuristics.
- Machine-learning approaches for per-client dynamic thresholds based on movement pattern, app needs, and AP load.
- Robustness to malicious APs and secure, privacy-preserving neighbor reporting.
- Cross-layer strategies that combine transport/application signals (e.g., TCP/QUIC throughput drops) with PHY metrics for smarter roaming.
- Standardization gaps: inconsistent client implementations of roaming hints reduce network-side gains.
