Wireless Module Partners

Leading wireless connectivity solution providers offer NXP wireless modules in their wireless connectivity solutions. Module manufacturers develop Wi-Fi modules using NXP’s broad portfolio of Wi-Fi chips (system-on-chip (SoC)), including Wi-Fi 6 chips, Wi-Fi and Bluetooth® combo integrated circuits (ICs) and tri-radio SoCs with 802.15.4. NXP enables a broad range of wireless applications with an ecosystem of wireless module partners.

Why Use a Module Vendor?

• Accelerate time-to-market
• Avoid the complexity of RF design and testing
• Ensure regulatory compliance more easily (e.g. FCC, CE, ISED)
• Focus on the host product’s functionality while relying on the vendor for wireless performance
