This intermediate CWAP training prepares network admins to analyze and troubleshoot wireless networks with a focus on advanced techniques and knowledge like protocol and spectrum analysis. The Certified Wireless Analysis Professional certification (CWAP) from CWNP is a professional-level certification. Does your shop have that one person who’s been around for a few years longer than everyone else and who gets called in to fix the really tough wireless issues? That’s the sort of person this CWAP course turns you into. Someone with their CWAP analyzes existing wireless network setups and configurations and makes sure they’re installed and running properly. Earning the CWAP is a great way to establish yourself as the local expert in wireless operations. Once you’re done with this Certified Wireless Analysis Professional (CWAP) training, you’ll know how to analyze and troubleshoot wireless networks with a focus on advanced techniques and knowledge like protocol and spectrum analysis.

For IT managers, this Networking training can be used to onboard new network admins, curated into individual or team training plans, or as a Networking reference resource.

CWAP: What You Need to Know

This Certified Wireless Analysis Professional training has videos that cover topics such as:

• 802.11 devices, protocols, and technologies
• Layer frame formats for wireless protocols
• MAC layer frame formats and technologies
• Spectrum and protocol analysis techniques and troubleshooting

Who Should Take CWAP Training?

This CWAP training is considered associate-level Networking training, which means it was designed for network admins. This WLAN skills course is designed for network admins with three to five years of experience with wireless networking.

New or aspiring network admins. This course covers advanced physical layer formats, MAC layer frame formats, wireless operations, as well as spectrum and protocol analysis and troubleshooting — that’s advanced stuff for someone who’s brand new to network administration or wireless administration. However, if you have to accelerate your wireless knowledge in a hurry, this is a good course to catapult yourself with.

Experienced network admins. If you’ve had a hand in wireless network administration and management for a few years but you’re not sure how to move your career forward, this CWAP training might be what you’re looking for. Learn advanced techniques in troubleshooting wireless networks while you learn everything there is to know about advanced wireless technologies and devices.
