7.1
Typical Application
7.1.1
BLE/2.4 GHz Radio Coexistence
The CC3235MODx 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 CC3235MODx 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
)
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.
