US Spectrum Allocation Details


#1

Hi,
I am looking for a detailed spectrum allocation guide for the US. Im
not
talking the default “US Frequency Allocations Chart.” but something
more
like a book or guide. Does such a thing exist?

Thanks in advance,
Isaac

That data is scattered all over the place at the moment, and we’ve had
to spend
a large amount of time digesting and marking it up. We’ll post our code
and
tidy XML representations of the data soon. Generally speaking, the
sources you
would have to dig through to get the full details of US spectrum
allocations are:

  1. The FCC regulations, 47 CFR, contain band allocations, power
    restrictions, etc.:

  2. Additional information on federal band allocations can be found in
    the NTIA
    Redbook:

    http://www.ntia.doc.gov/osmhome/redbook/redbook.html

  3. Most allocations to non-Federal organizations are in the FCC
    Universal
    Licensing System. You can download the entire contents of this database
    as
    delimited text files, but they’re an amazingly awful mess and require
    substantial pre-processing.

  4. AM, FM, and TV broadcast stations are in the FCC CDBS, which is not
    nearly
    as bad as ULS:

    http://www.fcc.gov/mb/databases/cdbs/

  5. Shortwave broadcast stations are on the FCC HF Broadcasting site:

    http://www.fcc.gov/ib/sand/neg/hf_web/seasons.html

  6. Federal allocations are listed in the NTIA Government Master File.
    This is
    a classified database, but we managed to get half of the GMF records in
    a FOIA
    request last summer, and we’ll be requesting an updated and expanded
    version.

  7. Some additional information is available in the FCC IBFS, COALS, and
    Equipment Authorization databases, and in various DISA JSC databases.
