Glade Creek Technology. Wireless Concepts. Wireless networks are made of low frequency light. It can help to think of an Access Point as a light bulb. .. Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies. 6-. 1. Chapter 6. Wireless and Mobile Networks.
