[CESG] Re: [SSG] [SANA #5270] AW: SCID assignments / Frequency Band Table

Wed Aug 5 17:42:47 UTC 2015

Gents,

I have no problem with consulting with Enrico on the deails.  But I do want to point out that what I think we need in this case is not a careful parseing of whether  S-Band is 2-4 GHz (IEEE) vs 2.60 – 3.95 GHz (Waveguide), but a small set of “Band Bins” and the associated frequencies, that will give us some SCID assignment breathing room.   I proposed that we create these “Band Bins”.  I’ve augmented those proposed Band Bins, below, with the frequencies that they include.

Purely based on pragmatic considerations I would suggest that we create “Band Bins” that looked like this:

·Everything below S-Band (HF, VHF, UHF, L)   0-2 GHz
·S-Band & C-Band   2-8 GHz
·X-Band   8-12 GHz
·K-Band (Ku, K, Ka) 12-40 GHz
·None or unstated

If we adopt this set of “Bins” or something similar, driven by a desire to partition the whole frequency spectrum into a small set of Bins, then it does not matter if UHF is wider or narrower, it is just a part of “Bin 1”, everything below S-Band (0-2 Ghz).

Regardless, let’s see what Enrico has to say when he is available.

Cheers, Peter

I also concur with Gippo that is good to have some “mentoring” from Enrico about this issue. The main problem in all these regulations, in my view, is the fact that the UHF band is larger in ITU than IEEE, thus possibly giving rise to some misunderstanding while reading UHF in the document even if the numerical frequency band is also given.

My two cents,

Tomaso

Peter,
        I prefer we consult (off line) Enrico when he is back to work.
As SLS-RFM Chair he is the best candidate for this topic.

Ciao

Gian Paolo

Hi Gippo,

I found the same problem when I did my research.  Perhaps we need to both state that we are using the IEEE conventions AND also put the frequencies in GHz as well as the band identifiers.  That must be unambiguous.

Would you agree?

Regards, Peter

Peter,
       you attached the following table for frequency bands, however my frequency guru (i.e. Enrico Vassallo) always warns me about using bands named with letters as this is not unique.
As you can see e.g. at https://en.wikipedia.org/wiki/Radio_spectrum there are clear difference between IEEE (compliant with your table, I think), ITU, and EU, NATO, US ECM frequency designations.
Regards

Gian Paolo
