Last week I spent some time doing half-day AirWave training road shows. Most of the folks in my classes were from small to medium size companies and the types of questions that I received really hit home that there is still a lot of wireless training that needs to be done to bring everyone up to speed.

For example:

• Why in the U.S. do we typically only use channels 1,6, and 11?
• Should all of my APs at a single site have the same SSID’s?
• What does RSSI and dbm mean when talking about wireless signals?

These are basic questions that all wireless administrators should understand.

There are several courses out in the market place today that try to address the basics of wireless networking. I would recommend some of the CWNP classes (www.cwnp.com). These courses are great for people who already understand some of the basic network concepts, but want to elevate their wireless knowledge level and increase their marketability to employers.
