Coexistence Modeling

Performance evaluation of Bluetooth systems in the presence of WLAN interference

Bluetooth® Toolbox features and reference examples enable you to evaluate the performance of Bluetooth basic rate/enhanced data rate (BR/EDR) and low energy (LE) systems in the presence of WLAN signal interference.

Use the coexistence modeling capabilities of the toolbox to:

  • Create and configure a shared channel between Bluetooth and WLAN.

  • Simulate and visualize noncollaborative coexistence between Bluetooth and WLAN and mitigate interference by using adaptive frequency hopping (AFH).

  • Select a Bluetooth LE channel index for connection, periodic advertising, and isochronous events.

  • Generate a Bluetooth BR/EDR hopping sequence for inquiry, paging, and connection procedures.

The Bluetooth LE piconet consisting of one Bluetooth LE Central and one Peripheral. The scenario consists of two WLAN nodes, that introduces interference in the Bluetooth LE signal.
