The Certified Wireless Specialist (CWS) is a certification that validates the
knowledge of wireless sales, marketing, entry-level support, and decision-making
professionals related to 802.11 wireless networks.
The learning materials explain the language of Wi-Fi as well as the typical
hardware and software used in wireless local area networks (WLANs). From radio
frequency (RF) to Wi-Fi client devices, the CWS learns the terminology and
processes of Wi-Fi.
Becoming a CWS:
The CWS certification is an entry-level WLAN certification from the
vendor-neutral CWNP organization that brought you CWNA and other advanced
certifications. To earn the CWS certification, you must pass an online exam with
a score of 70% or higher. Those desiring to work as instructors teaching CWS
classes must pass with a score of 80% or higher. Regardless of the way you
