Hop Dwell Period

This parameter specifies how long the system will stay on one

frequency before hopping to the next frequency in the pattern.

The maximum duration is set by the regulatory body for your

country. The limit for the United States is 400 ms (approximately

390 Kµsec). The default for Infrastructure Mode systems is

200 ms (approximately 200 Kµsec). Refer to the IEEE 802.11

Standard for more information on the hopping mechanism.

Beacon Period

This parameter specifies the duration between beacon packets

that are used by IEEE 802.11 systems to synchronize the “hops”

(change to another frequency). The beacon packet contains

timing information and hop pattern information that is broadcast

over the airwaves. Any station that can hear the beacon packet

can then synchronize their internal timer so that it can hop at the

correct time. The default beacon period is one-half of the dwell

period so two beacons are transmitted per hop dwell period

(default is 100 Kµsec). Refer to the IEEE 802.11 Standard for

more information on the hopping mechanism.

Wake Duration

This parameter specifies the amount of time per Hop Dwell

Period that the adapter stays awake listening for data packets.

This is only used in Power Save Mode.
