The frequency spectrum ranges from very low frequencies at 1 Hz to gamma rays at 10^23 Hz. Within that very large range of frequencies, there are three frequency bands used for wireless LANs. Those three bands are collectively referred to as Industrial, Scientific, and Medical (ISM) bands. Examples of applications in these bands include :microwave, ovens. These three bands represent unlicensed frequency bands on a worldwide basis. The frequency spectrum ranges from very low frequencies at 1 Hz to gamma rays at 10^23 Hz.
