Wireless LAN Technology
Associated Certification: CWTS
The CWTS certification is the entry-level
wireless certification for the IT industry
designed for WLAN sales and technical support
professionals
This certification will get you started in your
IT career by ensuring you have a solid base of
applicable knowledge of wireless LAN technology
and understanding "what it is, not how it works"
Benefits of Your CWTS Certification
Provides a competitive advantage by
differentiating one's knowledge and skill set on
WLAN technologies, allowing both sales and
support staff to excel respectively
An unparalleled source for gaining a solid grasp
on WLAN fundamentals and terminology
Delivers on the ability to describe features and
functions of wireless components, while
providing the skills needed to install and
configure wireless network hardware components
Makes sales and support personnel more
independent from the SE, while allowing SE's to
support a wider group
Course Summary
Duration: 2 days, Classroom
Prerequisites: A typical candidate should have a
basic understanding of data networking concepts
