Hop Set

The IEEE 802.11 Standard specifies three hop sets, which are pre-defined sets of frequencies that IEEE 802.11 Frequency Hopping systems MUST use. These sets have been chosen to minimize interference between nearby systems, and have been required by the various regulatory bodies in specific countries, such as the FCC in the United States, ETSI in Europe, and MKK in Japan. Refer to the IEEE 802.11 Standard for more information on hop sets.
