2-44
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 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 Value: 1
The following table displays the available spanning factors and
corresponding hopping sequences for 7 to 25 channels.
