5.15 BLE and WLAN Coexistence Requirements
For proper BLE and WLAN 2.4 GHz radio coexistence, the following requirements must be met:
PARAMETER
Port-to-port isolation
(1) The CC3235MODS modules are compatible with TI BLE modules using an external RF switch.
(2) A single antenna configuration is possible using the CC3x35 devices.
(3) For dual antenna configuration, the antenna placement must be such that isolation between the BLE and WLAN ports is at least 20 dB.

(1) °C/W = degrees Celsius per watt.
(2) These values are based on a JEDEC-defined 2S2P system (with the exception of the Theta JC [RΘ
JEDEC-defined 1S0P system) and will change based on environment as well as application. For more information, see these
