ORDER

Adopted: October 4, 2012


Released: October 5, 2012

By the Commission:
1.
On August 3, 2012, the Commission released a Second Report and Order, Second
Further Notice of Proposed Rulemaking, Second Notice of Inquiry, Order on Reconsideration, and
Memorandum Opinion and Order
in this proceeding.1 On our own motion, pursuant to Section 1.108 of
the Commission’s Rules,2 we issue this limited modification of the Wireless Backhaul 2nd R&O.3 We
are modifying one rule adopted in the Wireless Backhaul 2nd R&O to establish more efficient channel
assignments, consistent with the Commission’s intent to improve spectrum utilization in these bands.
2.
In the Wireless Backhaul 2nd R&O, the Commission allowed microwave operators to
create higher capacity links by authorizing 60 megahertz channels in the 5925-6425 MHz band (Lower 6
GHz band) and 80 megahertz channels in the 10700-11700 GHz band (11 GHz band), respectively.4 The

Other Uses and to Provide Additional Flexibility to Broadcast Auxiliary Service and Operational Fixed Microwave

from Mitchell Lazarus, Counsel for the Fixed Wireless Communications Coalition to Marlene H. Dortch, Secretary,
Federal Communications Commission (filed Aug. 23, 2012) (FWCC August 23 Ex Parte).

intent was to allow operators to combine existing 30 and 40 megahertz channels to create wider
channels.5
3.
Consistent with our normal practice in Part 101 of our rules, the Commission adopted a
rule specifying the channel center frequencies for the 60 and 80 megahertz channels in the Lower 6 and
11 GHz bands.6 The center frequencies contained in the rule as adopted, however, do not align the wider
60 and 80 megahertz channels with the existing narrower 30 and 40 megahertz channels. In the Lower 6
GHz band, the 60 megahertz channels are offset from existing channels upward by 4.945 megahertz.7 In
the 11 GHz band, the 80 megahertz channels are offset from existing channels downward by 10
megahertz.8 In each case, the offset results in inefficient spectrum usage because the wider channels
overlap with three narrower channels, which reduces the ability to coordinate multiple operations in the
same area.9 In contrast, if the wider channels were aligned with the narrower channels, each wider
channel would overlap only with two narrower channels. By changing the center frequencies specified in
the rule, we can match up the wider channels with the narrower channels. The center frequencies
specified in the Appendix will align the wider channels with narrower channels.
4.
As an example, the table below shows the band plan adopted in the Wireless Backhaul
2nd R&O for a portion of the 11 GHz band, including the misalignment between the 40 megahertz
channels and the 80 megahertz channels:

In contrast, under the band plan we adopt today, the 80 megahertz channels align with the 40 megahertz
channels:
10700 10715
10755 10795 10835 10875 10915 10955 10995 11035

5.
We act at this time in order to reduce burdens on applicants who wish to take full
advantage of the opportunity to use wider channels as contemplated in the Wireless Backhaul 2nd R&O.
Correcting the center frequencies will also provide certainty to equipment manufacturers as they develop
equipment for the wider channels. Absent action now, applicants that apply for wider channels would
have to either specify the offset channel center frequencies and possibly change frequencies later, or seek
a waiver to use non-offset channels, which would delay their ability to commence service. We see no
reason to delay action to correct our rules. Accordingly, we amend Section 101.147 of the Commission’s
rules as described in the attached Appendix in order to correct the center frequencies for 60 megahertz
channels in the Lower 6 GHz band and for 80 megahertz channels in the 11 GHz band.
6.
The actions contained herein have not changed our Final Regulatory Flexibility Analysis
(FRFA), which was set forth in the Wireless Backhaul 2nd R&O. Thus, no supplemental FRFA is
necessary. In addition, the action contained herein has been analyzed with respect to the Paperwork
Reduction Act of 1995 (PRA) and found to impose no new or modified reporting and/or recordkeeping
requirements or burdens on the public.
7.
Accordingly, IT IS ORDERED, pursuant to Section 4(i) of the Communications Act of
1934, 47 U.S.C. § 154(i), and Section 1.108 of the Commission’s Rules, 47 C.F.R. § 1.108, that the
Second Report and Order, Second Further Notice of Proposed Rulemaking, Second Notice of Inquiry,
Order on Reconsideration, and Memorandum Opinion and Order
, FCC 12-87, IS MODIFIED as set
forth herein.
