c. Define a different hopping sequence for each AU in order to minimize
interference between adjacent AUs.
! Hopping Band – Available in units with INT option only. Defines the
method of generating the basic hopping sequence. The available
selections are ISM US FCC, ISM International and Flexible
Hopping Definition.
" ISM US FCC: The basic hopping sequence is as defined in
the IEEE 802.11 standard and shown in Table 2-1. There are
79 hopping frequencies, using channels 2 to 80. (The
channel number is the distance in MHz from the beginning
of the frequency band, so that channel number 2 is at
5727MHz). Synchronization is not supported (Hopping Sync
parameter is set to Idle and cannot be changed).
" ISM International: The basic hopping sequence is as
defined in the IEEE 802.11 standard and shown in Table 2-
1. There are 79 hopping frequencies, using channels 2 to 80.
(The channel number is the distance in MHz from the
beginning of the frequency band, so that channel number 2
is at 5727MHz). Synchronization (Hopping Sync) is
supported.
" Flexible Hopping Definition: The Flexible Hopping
Definition menu should be used to define the basic hopping
sequence.
NOTE:
The same method for generating the basic hopping sequence (and the hopping shift
mechanism) should be used for all units in the system to enable SUs to communicate
with the AUs and to support radio planning that will provide minimal interference
between neighboring sectors.
NOTE:
In units that are configured in the factory to operate only in ISM US FCC hopping
standard (US Option), the Hopping Band menu is not available.
