But I see things, I read things, and I hear things as a busy citizen of the wireless world that bring me to the keyboard on this topic.

The Road to 200 CWNEs

The CWNP CWNE certification saw a greater than 20% growth in the year 2016. This includes only the approved CWNEs as of early November this year. With more applications in the pipeline, this is likely to result in a more than 25% growth rate in 2016 over 2015. Reaching 200 approved CWNEs is a significant milestone for this certification and the buzz in the field indicates a continued increase in growth rate for next year.
