The best way to prepare for this certification is to take the Cisco-approved training:

Designing Cisco Wireless Enterprise Networks (WIDESIGN)

This course offers a new perspective on designing wireless networks. Students will learn how to design a wireless network from the beginning to end, from customer-first contact to post-deployment reports. The student will learn how to conduct walk-throughs, identify difficult areas and optimize the survey process to provide a better AP-to-coverage ratio.

Deploying Cisco Wireless Enterprise Networks (WIDEPLOY)

This course prepares students to deploy wireless networks using Cisco controller and unified switching architectures policies and best practices, as well as ensure the proper implementation of mobility standards and configuration of wireless components. The course reinforces the instruction by providing students with hands-on labs to ensure students thoroughly understand how to configure and deploy the new Cisco 8.0, Prime Infrastructure release 2.2, and Mobility Services Engine release 8.0 features.

Troubleshooting Cisco Wireless Enterprise Networks (WITSHOOT)

This course prepares students with knowledge of troubleshooting and optimizing Enterprise wireless infrastructures. Students will learn about the tools and methodologies needed to identify and resolve client connectivity, performance, and RF issues.

Securing Cisco Wireless Enterprise Networks (WISECURE)

The course provides guidelines for implementing Wi-Fi security architectures through proper configuration of Cisco wireless components. Students will have access to hands-on labs to reinforce concepts that include deploying Cisco AireOS 8.0, Prime Infrastructure release 2.2, and Identity Services Engine release 1.3 features.
