From home appliances to industrial equipment, the demand for integrating Wi-Fi into just about everything has grown dramatically over the last few years, as demonstrated by the interest in the Internet of Things (IoT). Many designers are using “pre-certified modules” to embed this connectivity quickly and easily – at least, in theory. The reality is there are still many challenges to getting the end-product implementation certified as complying with mandatory, complex regulatory requirements for IEEE 802.11 wireless LANs (WLANs).

This course will look at compliance and certification issues, and how pre-compliance testing can make the path to final approval quicker, less costly, and less frustrating. It will also look at some of the complex, critical tests and masks that OEMs must use and pass, and how the right instrumentation can make this challenging aspect of design and approval go more smoothly when assessing factors such as transmit power, power spectrum density, occupied bandwidth, spectrum emission mask, and spurious emission measurements. Finally, it shows how combining correlated time- and frequency-domain measurements, plus error vector magnitude (EVM) display, can help in all aspects of debug, including transient performance, EMI issues, and more.
