  1. (a)2305-2320 MHz and 2345-2360 MHz bands. The following frequencies are available for WCS in the 2305-2320 MHz and 2345-2360 MHz bands:
    1. (1)Two paired channel blocks are available for assignment on a Major Economic Area basis as follows:
    2. (2)Two unpaired channel blocks are available for assignment on a Regional Economic Area Grouping basis as follows:
  2. (b)746-758 MHz, 775-788 MHz, and 805-806 MHz bands. The following frequencies are available for licensing pursuant to this part in the 746-758 MHz, 775-788 MHz, and 805-806 MHz bands:
    1. (1)Two paired channels of 1 megahertz each are available for assignment in Block A in the 757-758 MHz and 787-788 MHz bands.
    2. (2)Two paired channels of 1 megahertz each are available for assignment in Block B in the 775-776 MHz and 805-806 MHz bands.
    3. (3)Two paired channels of 11 megahertz each are available for assignment in Block C in the 746-757 MHz and 776-787 MHz bands. In the event that no licenses for two channels in this Block C are assigned based on the results of the first auction in which such licenses were offered because the auction results do not satisfy the applicable reserve price, the spectrum in the 746-757 MHz and 776-787 MHz bands will instead be made available for assignment at a subsequent auction as follows:
      1. (i)Two paired channels of 6 megahertz each available for assignment in Block C1 in the 746-752 MHz and 776-782 MHz bands.
      2. (ii)Two paired channels of 5 megahertz each available for assignment in Block C2 in the 752-757 MHz and 782-787 MHz bands.
  3. (c)698-746 MHz band. The following frequencies are available for licensing pursuant to this part in the 698-746 MHz band:
    1. (1)Three paired channel blocks of 12 megahertz each are available for assignment as follows:
    2. (2)Two unpaired channel blocks of 6 megahertz each are available for assignment as follows:
  4. (d)1390-1392 MHz band. The 1390-1392 MHz band is available for assignment on a Major Economic Area basis.
  5. (e)The paired 1392-1395 and 1432-1435 MHz bands. The paired 1392-1395 MHz and 1432-1435 MHz bands are available for assignment on an Economic Area Grouping basis as follows: Block A: 1392-1393.5 MHz and 1432-1433.5 MHz; and Block B: 1393.5-1395 MHz and 1433.5-1435 MHz.
  6. (f)1670-1675 MHz band. The 1670-1675 MHz band is available for assignment on a nationwide basis.
  7. (g)[Reserved]
  8. (h)1710-1755 MHz, 2110-2155 MHz, 1695-1710 MHz, 1755-1780 MHz, and 2155-2180 MHz bands. The following frequencies are available for licensing pursuant to this part in the 1710-1755 MHz, 2110-2155 MHz, 1695-1710 MHz, 1755-1780 MHz, and 2155-2180 MHz bands:
    1. (1)Four paired channel blocks of 10 megahertz each are available for assignment as follows:
    2. (2)Six paired channel blocks of 5 megahertz each are available for assignment as follows:
    3. (3)One unpaired block of 5 megahertz and one unpaired block of 10 megahertz each are available for assignment as follows:
      1. (i)Frequency assignments for the BRS/EBS band.
        1. (1)[Reserved]
        2. (2)Post transition frequency assignments. The frequencies available in the Broadband Radio Service (BRS) and Educational Broadband Service (EBS) are listed in this section in accordance with the frequency allocations table of § 2.106 of this chapter.
          1. (i)Lower Band Segment (LBS): The following channels shall constitute the Lower Band Segment:
          2. (ii)Middle Band Segment (MBS): The following channels shall constitute the Middle Band Segment:
          3. (iii)Upper Band Segment (UBS): The following channels shall constitute the Upper Band Segment:
        3. (3)-(5) [Reserved]
  9. (j)2000-2020 MHz and 2180-2200 MHz bands. The following frequencies are available for licensing pursuant to this part in the 2000-2020 MHz and 2180-2200 MHz (AWS-4) bands:
    1. (1)Two paired channel blocks of 10 megahertz each are available for assignment as follows: Block A: 2000-2010 MHz and 2180-2190 MHz; and Block B: 2010-2020 MHz and 2190-2200 MHz.
