Rick,
I suspect some MSO's would not agree with 8 MHz spectrum chunks, 6 would
also be objectionable to some. That leaves 2 MHz or 96 bits. Might work if
someone were to make such a proposal.

Duane, thank you.
If we choose 8Mhz as the fixed block, 192MHz/8Mhz = 24 bits are needed to
represent the EPoC band. For exclusion bands, various pieces can be
similarly and explicitly defined by a separate bit map. As a result, this
approach can either have a single bit map to represent either EPoC
(inclusion) band or exclusion band, or both (the two bit maps would be a
full set representing the entire spectrum from lower limit to upper limit
bound).
Best, Rick

Rick,
Currently we have not set a limit on the number of internal exclusion bands.
I recall this being briefly mentioned some time ago but I am not aware of
any straw poll of vote on the idea. I suspect operators are well aware that
if they chop up the spectrum they will get less than optimal performance.
The bit mask idea has not been proposed at this point (I'm assuming you
would need a mask of 192 bits, is that the idea?). You are certainly free to
make such a contribution. IEEE is contribution driven as I'm sure you are
aware.
These questions would be addressed in the RF Spectrum Ad Hoc not the Channel
Model.

Duane and all,
(1) With up to 3 exclusion bands, and the minimum contiguous DS spectrum
of 24MHz, it is likely to create small fragments of unusable spectrum in
between the exclusion bands and EPOC bands, especially below 1002MHz as
there are various existing services and different regions/MSOs have
different channel allocations.
(2) Are three exclusion bands adequate or there might be scenarios where
more than 3 exclusion bands may be valuable or even necessary (to protect
pieces of legacy services for example)?
(3) Instead of trying to define up to three exclusion bands of variable
width, should we entertain the approach where many fixed width (small)
exclusion bands can be use and represented by a bit map and bit mask? For
example, 8MHz (or 6MHz) fixed width, if a bit is set in the mask, then this
band is excluded.
As I have not been able to attend the channel Ad hoc, perhaps these
questions were already discussed and addressed.
Best, Rick
