10.1.1 BLE/2.4 GHz Radio Coexistence

The CC3135MOD 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 CC3135MOD 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, Dual Antenna)
    • Dual-band Wi-Fi (see Figure 10-1)

      In this mode, the WLAN can operate on either a 2.4 or 5 GHz band and Bluetooth® low energy operates on the 2.4 GHz band.

Figure 10-1 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.
