10.1.1 BLE/2.4 GHz Radio Coexistence

The CC3135 device is designed to support BLE/2.4 GHz radio coexistence. Because WLAN is inherently more tolerant to time-domain disturbances, the coexistence mechanism gives priority to the Bluetooth® low energy entity over the WLAN. Bluetooth® low energy operates in the 2.4 GHz band, therefore the coexistence mechanism does not affect the 5 GHz band. The CC3135 device can operate normally on the 5 GHz band, while the Bluetooth® low energy works on the 2.4 GHz band without mutual interference.

The following coexistence modes can be configured by the user:

  • Off mode or intrinsic mode

    • No BLE/2.4 GHz radio coexistence, or no synchronization between WLAN and Bluetooth® low energy—in case Bluetooth® low energy exists in this mode, collisions can randomly occur.

  • Time Division Multiplexing (TDM, Single Antenna)
    • 2.4 GHz Wi-Fi band (see Figure 10-1)

      In this mode, the two entities share the antenna through an RF switch using two GPIOs (one input and one output from the WLAN perspective).

    • 5 GHz Wi-Fi band (see Figure 10-2)

      In this mode, the WLAN operates on the 5 GHz band and Bluetooth® low energy operates on the 2.4 GHz band. A 2.4- or 5 GHz diplexer is required for sharing the single antenna.

  • Time Division Multiplexing (TDM, Dual Antenna)
    • 2.4 GHz Wi-Fi Band (see Figure 10-3)

      In this mode, the two entities have separate antennas. No RF switch is required and only a single GPIO (one input from the WLAN perspective).

    • 5 GHz Wi-Fi band (see Figure 10-4)

      In this mode, the WLAN operates on the 5 GHz band and Bluetooth® low energy operates on the 2.4 GHz band. No diplexer is required for the dual-antenna solution.

Figure 10-2 shows the single antenna implementation of a complete Bluetooth® low energy and WLAN coexistence network with the WLAN operating on either a 2.4- or a 5 GHz band. The SOP lines control the 5 GHz switch. The Coex switch is controlled by a GPIO signal from the BLE device and a GPIO signal from the CC3135 device.

Figure 10-3 shows the dual antenna implementation of a complete Bluetooth® low energy and WLAN coexistence network with the WLAN operating on either a 2.4- or a 5 GHz band. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3135 device is required.

Figure 10-4 shows the dual antenna implementation of a complete Bluetooth® low energy and WLAN coexistence network with the WLAN operating on either a 2.4- or a 5 GHz band. In this case, the 2.4 GHz and 5 GHz Wi-Fi share an antenna and the BLE has it's own dedicated antenna. The SOP lines control the 5 GHz switch. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3135 device is required.
