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 collaborative coexistence between Bluetooth and WLAN by using PHY packet traffic arbitration.

  • 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.

To use the network simulation functionality for modeling Bluetooth and WLAN coexistence, install the Communications Toolbox Wireless Network Simulation Library add-on.

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