Default When does channel changing DSSS become hybrid DSSS/FHSS?


wrote in message
ups.com...
Does anyone know how frequently a DSSS system may change channels?


A dozen or more times per hour.


At
some point it has to resemble a frequency hopping system enough that it
falls under the rules reguarding hybrid DSSS/FHSS systems.
47 CFR Part 15 section 15.247(g) does say that "a [hybrid]system
employing short transmission bursts must comply with the definition
of a frequency hopping system and must distribute its transmissions
over the minimum number of hopping channels
specified in this section. "



Those rules are outdated and no longer apply in this situation.



This seems to suggest at least that a bursty DSSS system that changes
channels must follow the rules for FH.

Can anyone out there clarify things?



Just continue using your channel changing DSSS and don't worry.
Technology is growing too quickly for the FCC bureaucrats to
keep up.
