What is Reddit's opinion of CWNA Certified Wireless Network Administrator Study Guide: Exam CWNA-108?

From 3.5 billion Reddit comments

Look at the CWNA curriculum. Vendor neutral and comprehensive look at wireless. CWNA is the comprehensive "intro" (though much deeper than a typical intro) to the CWNP program. A CWNA would give you a great foundation in wireless - even if you didn't want to go any further in the program. This book is the holy grail of CWNA level material. I linked the new version that is coming out in March but you could get the current version as well.

If you do decide you like it and want to go further, there are several professional level certs/curriculum that go more in depth into design/security/analysis. They have also recently released new certs and training around non-Wifi wireless technologies (like Zigbee,etc) that are used in IOT-centric areas.

Ok.

WiFi for one room in an office for a dozen people is easy.
One good AP can solve that problem.

Solving WiFi coverage for a production floor (a manufacturing space, I assume) can be a much different problem.

Manufacturing equipment with all that heavy steel will obstruct the RF waves and cause dead spots.

Some manufacturing equipment can also radiate powerful RF that essentially "jams" the WiFi.

So, positioning APs in appropriate locations, and using directional or other antenna options with enhanced sensitivity will all depend on the site survey.

Maybe you won't need to do anything extra. Just throw four or five APs on the ceiling and move on with your life.

Maybe you'll need to deploy seventeen APs with an array of fancy antenna options to overcome various obstacles or challenges.

This book will probably be the best path towards understanding the challenges:

My honest advise is to hire a professional for this job.

Jump straight to the CWNA. CWT is focused more on what you're already doing, basically field work. And I agree with /u/WearyIntention, Sybex study guide is known as the wifi bible for a reason.

Get this, study it, take the CWNA.

This one is MUCH better. CWNA Sybex from Westcott and Coleman. It's basically the WiFi Bible.

Check out this book if your curious. It's an incredible resource.
