Course Description

The CWTS™ (Certified Wireless Technology Specialist) Certification is the latest certification from the CWNP Program.  CWTS is an entry-level enterprise WLAN certification, and a recommended pre-requisite for the CWNA certification. The CWTS certification is the first high-stakes certification geared specifically towards both WLAN sales and support staff for the Enterprise WLAN industry.

The CWTS Certification verifies sales and support staffs are specialists in WLAN technology and have all the fundamental knowledge, tools and terminology necessary to be successful in the exciting and rapidly growing Enterprise WLAN industry.

CWTS was created in response to a strong market demand for professionals who are required to be proficient in a variety of basic wireless technologies. The vast numbers of system and network administrators whose responsibilities now include some work with wireless as well as wired networks require basic familiarity with terms, concepts, tools, and technologies.

As individuals, businesses, and organizations demand easier access to information, technology continues to evolve to meet the demand. One significant contribution has been the development and growth of wireless technology. In this course, you will explore the fundamentals of wireless technology and configuring wireless solutions.

Prerequisites

Essentials for CompTIA Network+ Certification
Networking Fundamentals Lifetime Certification
Prerequisite Knowledge for Cisco & Microsoft Certifications

 

Benefits of the 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

  • According to the Certification Magazine 2007 Salary Survey, entry level CWNP certification holders earn an average annual salary of more than $67,000

  • 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.

  • CWTS is the replacement certification for Wireless#, which has been discontinued. All Wireless# holders have been grandfathered into the CWTS certification.
