Overview
Plan and install a 100% wireless network coverage 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.
The five-day Certified Wireless Infrastructure Technician (CWIT®) is a comprehensive program perfect for those with 2-3 years’ experience within network infrastructure who wish to extend their knowledge, practical hands-on skills, qualifications and certifications into the wireless infrastructure environment.
Learners will expand their knowledge and skills to gain a thorough understanding of current and emerging wireless networking technologies used for in-building wireless coverage. Methods used for connection to backbone networks also feature with explorations into the principles of microwave access radio, fibre systems and cable technologies such as DSL. The organisation and management of site records and wireless system test results through OEM software is also included.
Practical hands-on sessions are incorporated throughout this program, including a focus on advanced wireless infrastructure troubleshooting, wireless coverage surveys and network testing tools. The organisation and management of site records and wireless system test results through OEM software is also included. A certified CWIT® will be undaunted when dealing with escalations and problem resolution within a strategic wireless network project.
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 centre sectors.
The CWIT® program is classroom-based and led by one of CNet’s expert Instructors.
Prerequisites
A minimum of two years installation experience within the network infrastructure sector is required. Successful completion of the Certified Network Cable Installer (CNCI®) program would be advantageous. If you would like to discuss your experience or suitability for this program please contact us.
