Valid values: 1 to Number of Hopping Frequencies minus
1, provided it meets the GCD requirement as described
above.
It is not recommended to use spanning factors of 1 and
N-1, as they result in hopping on consecutive channel
(assuming that the available channels are consecutive). In
these cases the advantage of using frequency hopping is
not fully utilized, since a narrow band interference may
affect several consecutive hops. Spanning factors of 2 and
N-2 also result in a relatively poor spread of the hopping
frequencies over the available frequency band.
Default Vale: 1
Table 2-5: Spanning Factors and Hopping Sequences for Sequences with 7 to 25
Channels
NOTE:
During the association process, the SU learns the Scrambling Mode
(and the Spanning Factor if applicable) of the AU. If the Scrambling
Mode of the AU is different from the one configured for the SU, than
after completing the association process the SU will use the
Scrambling Mode of the AU.
