So, which Wi-Fi radio interface is best for your application?

While this guide was written specifically for device manufacturers who need to integrate Wi-Fi for the NXP i.MX 6 and i.MX7 platform, the general principles are not specific to NXP application processors. Based on Silex Technology’s decades of experience providing embedded networking solutions, we have written this guide to help you understand the pros and cons of different Wi-Fi radio options.
This white paper will focus on the impact that the radio’s host bus has on the system performance. First, the PCIe and SDIO communications busses will be explained in a general overview. Power considerations for both busses will be discussed and analyzed. Finally, actual throughput testing results will be provided as real-world performance examples.

This white paper will help you learn about:

• Wi-Fi Radio Interface Options and NXP i.MX6 and i.MX7 Support 
• Theoretical Maximum Throughput (PCIe and SDIO Radios).
• PCIe and SDIO Driver Architecture Overview 
• Power Considerations for SDIO and PCIe radios
• Real World Throughput Testing Results (SDIO and PCIe Radios)
