Advanced (Ad Hoc/IBSS)

In Ad Hoc Mode, you can also modify the following parameters:

• Hop Set

• Hop Pattern

• Hop Dwell Period

• Beacon Period

• Wake Duration

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.

Hop Pattern

The hop pattern specifies the starting point in the given hop set.

Having a different hop pattern (along with different hop sets) lets

you place several different RF networks in close proximity with

minimal interference. In addition, this also provides an

additional level of security, since it is difficult to eavesdrop if you

do not know the hop pattern. Refer to the IEEE 802.11 Standard

for more information on hop patterns.
