SmartMesh Auto-Topology

commercial access point

Each Mesh AP constantly advertises its potential throughput

Each AP picks the best (potentially fastest) path to the root AP

Smart Wi-Fi selects best signal path to each client and adjacent AP

Maximizes backhaul speed without adjacent AP interference

If mesh node fails, SmartMesh self-heals

commercial access point

Each Mesh AP constantly advertises its potential throughput

AP’s own current potential throughput, and

Current potential throughput of its uplink (backhaul and upstream AP’s current potential throughput)

Mesh APs will re-route if a far superior path becomes available
