Re: [STDS-802-3-EPOC] Slides from today's RF Spectrum call



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.
Best Regards,
Duane

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
