Texas Instruments provides a recommended PCB layout guide in the CC3351EMUBGTR evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
To minimize power consumption, configure the device to use the lowest possible frequency, disable unnecessary peripherals, and use the power-saving modes (e.g., LPDS, Hibernate) when the device is not actively transmitting or receiving data. Refer to the CC3351 Power Management Guide for more information.
The maximum transmit power of the CC3351ENJARSBR is +20 dBm (100 mW) for IEEE 802.11b/g/n and +18 dBm (63 mW) for IEEE 802.11a/n/ac. However, the actual transmit power may vary depending on the specific application, antenna, and regulatory requirements.
Implement Wi-Fi coexistence by using the CC3351's built-in coexistence features, such as Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC). Additionally, use the device's APIs to implement custom coexistence algorithms and prioritize traffic based on the specific wireless technology requirements.
Texas Instruments recommends using a monopole or dipole antenna design with a gain of 2-3 dBi for optimal Wi-Fi performance. The antenna should be placed at least 10 mm away from the PCB edge and oriented perpendicular to the PCB to minimize interference.
