This entry-level certification (Certified Wireless Technician - Exam CWT-101) is offered by Certified Wireless Network Professionals, or CWNP, as part of a vendor-neutral wireless certification program.
According to CWNP, the Certified Wireless Technician (CWT) should be able to install APs based on a design document, configure the AP for initial operations and ensure connectivity, troubleshoot basic problems, and assist users in-person or through remote communications in problem resolution. Perhaps the most important skill is the ability to set up a WLAN client for connectivity, including SSID configuration, security settings, and other client adapter settings.
