Typical Application

7.1.1

BLE/2.4 GHz Radio Coexistence

The CC3235MODAx 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 CC3235MODAx 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 7-1)

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.
