Certified Wireless Infrastructure Technician (CWIT®)

An Award Winning Program - The Certified Wireless Infrastructure Technician (CWIT®) won The Innovation Award 2021 from Network Computing.

Learn how to plan and install a wireless network to facilitate high speed access for smart mobile devices. Using the latest wireless technologies, ensure all users have comprehensive access at all times to benefit from a seamless roaming experience.

Program Overview

The Certified Wireless Infrastructure Technician (CWIT) is a comprehensive program, made up of 30% theory work, 20% case studies and 50% practical work.

Learners can take their existing network cabling knowledge and skills to the next level by gaining a valuable insight into current and emerging wireless networking technologies used to provide in-building wireless coverage. Methods used for connection to backbone networks also feature with explorations into the principles of microwave radio bearers, fibre systems and cable technologies. Each subject area covers the latest standards and codes of practice and ensures technicians are armed with everything they need to undertake installation projects to the highest possible standards.

Focused practical hands-on sessions are incorporated throughout this program, including a focus on advanced wireless infrastructure installation, troubleshooting, wireless coverage surveys and network testing tools. The organization and management of site records and wireless system test results through OEM software is also included.

The duration of this program is five days; the content is comprehensive and detailed, allowing network infrastructure professionals to have the potential to add real value to their skills by including these complex areas in their product portfolio. A qualified CWIT will be undaunted when dealing with escalations and problem resolution within a strategic wireless network project.

On successful completion, learners can demonstrate the highest levels of competency and can feel confident that they possess the very latest technical abilities within these fields of installation and feel confident that they are progressing through The Global Digital Infrastructure Education Framework. They also gain an internationally recognized BTEC Level 4 qualification and CWIT certification - providing the use of post nominal letters after their name and the use of the official CWIT logo.

A certified CWIT also considers the requirements for compliance, having a full understanding of national and international regulations, codes and standards. During the program, learners will be provided a valuable opportunity to access the latest industry standards.

Following this program, you are encouraged to continue your professional development by advancing your knowledge and skills to gain further official certifications and qualifications by progressing through The Global Digital Infrastructure Education Framework which maps education programs to career advancement throughout the network infrastructure and data center sectors.

The CWIT program is classroom-based and led by one of CNet’s expert Instructors.
