CWSS case studies
CWSS · Put your knowledge to work in context.
The Certified Wireless Sales Specialist (CWSS) is an entry-level WLAN certification from CWNP, the vendor-neutral organization behind CWNA and the advanced Wi-Fi certifications. It 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 - so candidates learn the terminology and processes of Wi-Fi rather than deep engineering. The current exam, CWSS-102, was released in July 2024 and replaced the former Certified Wireless Specialist (CWS) certification; existing CWS holders are automatically updated to CWSS. The CWSS case studies are 5 cases and about 4,019 words.
