CWTS case studies
CWTS · Put your knowledge to work in context.
CWTS (Wi-Fi Fundamentals), also catalogued as the Certified Wireless Technology Specialist under exam number PW0-071, was a sales-and-support-level wireless LAN certification in the CWNP program. It was designed for IT sales and support professionals rather than for hands-on network engineers, and it validated a working understanding of the basics of enterprise 802.11 wireless networks: hardware and software, security and compliance, and the "who, what, why" of radio frequency. The CWTS case studies are 5 cases and about 2,973 words.
