Coexistence Modeling
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 and New Radio (NR) signal interference.
Use the coexistence modeling capabilities of the toolbox to:
Simulate Bluetooth LE in 6 GHz supporting channel access mechanisms such as listen before talk (LBT), spectrum sensing based deferral (SSBD), and detect and avoid (DAA).
Create and configure a shared wireless channel between Bluetooth and WLAN.
Simulate and visualize noncollaborative coexistence between Bluetooth and WLAN and mitigate interference by using adaptive frequency hopping (AFH).
Simulate and visualize collaborative coexistence between Bluetooth and WLAN by using PHY packet traffic arbitration (PTA).
Configure Bluetooth channels for LE connections, LE Audio, LE advertisement, and BR/EDR connections.
Measure key performance indicators (KPIs) such as throughput, latency, packet delivery ratio (PDR), and packet loss ratio (PLR) at both the node and network levels to analyze the network and the effect of interference.
To use the network simulation functionality for modeling Bluetooth and WLAN coexistence, install the Communications Toolbox Wireless Network Simulation Library add-on.
