Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years. I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!
I worked with a customer recently who was convinced the ISM band was only for 2.4 GHz band. Which is 100% incorrect! Here is a refresher …
The ISM (In the ISM Band) stands for "industrial, scientific and medical" radio bands. The ISM includes the following frequencies:
902 - 928 MHz (26 MHz in width)
2.400 - 2.4835 GHz (83.5 MHz in Width)
5.725 - 5.875 GHz (150 MHz in Width) ** Note 5.8 GHz ONLY**
This ISM bands were defined by the ITU Telecommunication Standardization Sector
The ISM bands are governed by the FCC here in the United States and they are unlicensed. This is found under title 47, part 18.
Although the band is labeled as “industrial, scientific and medical” bands -- you will find almost everything and anything under the sun that is unlicensed in these frequencies. You name it, it rides these waves. WiFi, cordless phones, Mircowave ovens, Bluetooth, toys, baby monitors, wireless cameras, etc !
