6. We adopt, with minor variations, the
7. We adopt Comsearch's proposal to implement the proposed standards as Category B2 and keep the existing standards as Category B1, allowing applicants to choose between those standards. That approach will maximize flexibility for applicants and allow existing licensees to keep their antennas. We also adopt FWCC's and Comsearch's proposal to slightly loosen the proposed antenna standards for the 18 GHz band. No party argued that the revised standards would raise any interference concerns in any of the relevant bands.
8. We do not adopt Comsearch's proposal to adopt a power limit on licensees using smaller antennas. Adopting a power limit may artificially limit path length because path length is directly related to the EIRP. A particular path will require operation at the same EIRP whether the operator uses a Category A antenna or a Category B antenna. When EIRP is equivalent, a Category B antenna will radiate more energy in the side lobes than a Category A antenna. In areas where another operator is not in proximity, for example, rural and other uncongested areas, the extra side lobe radiation will not cause any additional interference. In those areas, a licensee can use a smaller and cheaper antenna without harming other FS operators. If we were to restrict power across the board, there may be instances where operators may not be able to realize the full benefits of smaller antennas. We find that our existing rules are sufficient to protect against the potential for increased side lobe radiation. If interference occurs, the rules require the licensee to upgrade its
9. We find that permitting smaller antennas in the 6, 18 and 23 GHz bands will benefit operators and consumers alike and that these benefits outweigh any potential costs. Our actions today will enable these spectrum bands to be used more intensively for wireless backhaul, public safety, and other critical uses. Even for a single link, which consists of two transmitters and two antennas, the cost savings from allowing smaller antennas can be substantial. Savings in installation costs for the link would likely be over $2,000 for two antennas. MetroPCS estimates that if a smaller antenna eliminates the need for wind loading studies or structural changes to a tower, the cost savings could run “into the tens of thousands, if not hundreds of thousands, of dollars.” There would also be savings in operational costs. For example, if an operator using a 6 GHz link is able to use 3-foot antennas instead of 6-foot antennas, its site rental costs could decrease by $7,200 each year. There are also additional cost savings noted by FiberTower and others. When those cost savings are multiplied by the thousands of links that are authorized in the 6 GHz band each year, even if a relatively small percentage of authorized links could use smaller antennas, there could be many instances where operators could recognize cost savings. While the cost savings in the 18 and 23 GHz bands would be smaller, since there is less difference in the size of antennas, there would still be cost savings. On the other hand, there is some risk that a carrier taking advantage of these new rules may have to upgrade to a Category A antenna later. We believe that in many cases, this potential cost will be discovered and avoided in the coordination process. We also note that licensees are not required to use smaller antennas.
10. To promote efficient frequency use for various channel sizes in certain part 101 frequency bands, § 101.141(a)(3) of the Commission's rules requires FS operators to establish minimum payload capacities (in terms of megabits per second) and minimum traffic loading payloads (as a percentage of payload capacity). That rule lists a “minimum payload capacity” for various nominal channel bandwidths. The term “payload capacity” is not defined. The same rule also defines “typical utilization” of the required payload capacity for each channel bandwidth as multiples of the number of voice circuits a channel can accommodate.
13. FWCC had originally recommended adoption of the efficiency requirements using bits/second/Hertz values adopted by Industry Canada, with appropriate adjustments for bands where Canada does not have FS services. Comsearch supported those standards. FWCC subsequently proposed an adjustment that would continue to express the standards based on bits/second/Hertz but tighten the standards for certain channel bandwidths in the 11 GHz and 13 GHz bands.
14. First, we convert the current voice-circuit based efficiency standards to bit/second/Hertz standards using standards recently proposed by FWCC. Commenters generally support the idea of replacing our existing payload capacity requirements with efficiency requirement expressed in terms of bits-per-second-per-Hertz. We have reviewed the most recent standards proposed by FWCC, and find that they closely approximate what our current rules require and are otherwise appropriate. This action will allow our payload capacity requirements to reflect modern technologies. Furthermore, if we allow new channel bandwidths in microwave bands, a bit/second/Hertz standard will automatically accommodate new channel bandwidths.
15. FWCC and Comsearch support the proposed definition of payload capacity as consistent with industry practice. We adopt the proposed definition because it is useful to define that term in our rules and the proposed definition is appropriate.
16. A second and related issue is the definition of “throughput” for purposes of the efficiency standards. The definition is important because FS operators use a variety of network configurations, and using an unnecessarily restrictive definition of throughput can prevent operators from using some of those network configurations. We consider two proposals offered by commenters and adopt an approach that meets both of their objectives.
17. Clearwire supports the idea of adjusting the minimum payload requirements to account for the increased capacity that would be available with wider bandwidth channels. It expresses concern, however, that simply establishing a bits/second/Hertz standard may not be appropriate for modern network topologies. Clearwire uses an Ethernet-based microwave mesh that relies on a ring topology to provide 99.999 percent network availability by providing redundant link diversity from every cell site location. Normally, a ring is split in half with traffic travelling clockwise on one half and counterclockwise on the other half. If a radio fails on a link, the traffic is aggregated and re-routed around the failed/downed link. Because each link must be designed to carry enough data to accommodate failures elsewhere in the system, the links must be designed to be less than fully loaded during normal operation. Clearwire proposes that the Commission require
18. FWCC recommends a different approach. FWCC asks that we drop the voice circuit designations in § 101.141(a)(6) and (7) of the Commission's rules, which define “loading” for purposes of existing rules, and replace them with a new § 101.141(a)(6) to read as follows: “Digital systems using bandwidths of 10 megahertz or larger will be considered 50% loaded when at least 50% of their total payload capacity is being used.”
19. We believe the objectives behind the Clearwire and FWCC proposals can be met through a simpler approach. Therefore, we update our existing traffic loading requirements, which are not expressed in terms of actual data throughput but in terms of the capacities of multiplexers attached to the transmitters. The definition we adopt today will ensure the efficient use of spectrum while allowing operators to use network configurations with redundant links in order to maintain continuity of service if a link fails. While we update our definition to take into account current technologies, the definition we adopt uses an approach that is consistent with our current rule.
20. To harmonize the proposals and respond to concerns expressed by Comsearch, FWCC, Clearwire and other commenters, we replace § 101.141(a)(6) and (7) with the following new § 101.141(a)(6) to read as follows: “Digital systems using bandwidths of 10 MHz or larger will be considered 50 percent loaded when at least 50 percent of their total capacity is being used. For purposes of this subsection, a Fixed Service channel is being used if it is attached to a communications system that is capable of providing data to it at a rate that is sufficient to occupy at least 50 percent of the payload capacity of the Fixed Service channel, after header compression is applied.”
21. This definition should ensure that FS systems will be designed to carry the amount of data that is likely to be transmitted over them after IP radio systems remove extraneous header data, to the extent licensees use transmission systems that remove such data. It should also accommodate the needs of operators that deploy FS links in ring topologies, where excess capacity is needed to ensure network reliability.
22. In the
23. We adopt a new policy, the Rural Microwave Flexibility Policy, designed to provide operators relief, through our waiver process, from the efficiency standards that may not be necessary in noncongested rural areas. Granting licensees in noncongested areas relief from these efficiency standards can facilitate the use of microwave backhaul in rural areas by allowing substantial cost savings in deployment. Indeed, granting relief from the efficiency standards could allow the use of microwave in areas where such use would not be economically feasible under the current rules. In adopting this policy, we take into consideration concerns raised by commenters and institute a series of criteria to ensure that relief is appropriately tailored. If experience with this Policy suggests that a rule change is warranted in the future, we will reconsider that possibility at the appropriate time.
24. Exempting licensees from the efficiency standards in noncongested areas can reduce the cost of deploying microwave backhaul facilities and substantially increase possible path lengths, thereby spurring deployment of broadband in rural areas. The benefits of relaxing efficiency standards in rural areas could be considerable. For example, in 2010, Sprint, FiberTower, and the Rural Telecommunications Group estimated the cost of deploying and operating a 6 GHz link covering 100 miles and requiring four different relay towers would be over $3 million. Additionally, FWCC has demonstrated that allowing a 6 GHz licensee to vary its modulation between 256 Quadrature Amplitude Modulation (a throughput of 208 Mbps) and Quadrature Phase Shift Keying (a throughput of 45 Mbps, about one-fifth of the throughput of 256 QAM) could extend the usable length of a link from 24.56 kilometers to 66.45 kilometers, because the lower throughput allows the operator to maintain reliability over a longer distance.
25. An increase in usable path length would allow some operators to replace multiple paths with single paths. For each intermediate relay station that could be eliminated, the operator would save the cost of a transmitter, antenna, and site rental for that relay site. If one uses the $3 million cost estimate provided by Sprint, FiberTower, and the Rural Telecommunications Group, and assumes that each station contributes equally to the overall cost of the link (two end stations and four intermediate relay stations), the cost of each intermediate relay station would be approximately $500,000. A review of our licensing data shows that there are over 22,000 stations in the 6 GHz and 11 GHz bands that currently use Category B antennas that would potentially be eligible for such relief. Moreover, there may be many more sites where microwave service is not yet deployed because of the prohibitive cost of multiple hops. In these cases, a more flexible policy could spur increased broadband “middle mile” deployment.
26. Even if an intermediate relay station cannot be eliminated, providing relief from the minimum payload capacity rule can result in cost savings. Allowing use of lower data rates could allow licensees to use less expensive transmitters and lower power, both of which would result in cost savings. Under the revised minimum capacity requirements that we are adopting in this order, for example, a transmitter operating with a bandwidth of five
27. Several commenters express concerns about the proposal in the
28. We recognize commenters' concerns about the impact of providing relief from efficiency standards in rural areas, but we find there is a better approach than the alternatives presented. FWCC and Comsearch are concerned that providing relief from the minimum payload capacity requirements will provide incentives for licensees to use Category B antennas, which can increase interference. We do not agree with FWCC and Comsearch that allowing adaptive modulation and smaller antennas can be a substitute for relief from efficiency standards, because granting appropriate relief from the efficiency standards can result in much greater cost savings in rural areas. We disagree with those commenters who suggest that granting relief from the traffic loading standards would be an adequate substitute for granting relief from the minimum payload capacity requirements. If we merely provided relief from the traffic loading requirements, FS operators would have to build links that were fully capable of meeting the minimum payload capacity requirements. Denying permission to reduce payload capacities in such areas would all but eliminate any cost savings that would otherwise be made possible by reducing loading percentages alone, because most of the savings associated with granting relief from the efficiency standards would result from reduced up front equipment costs, as opposed to operating costs.
29. Given the concerns presented in the record, we opt to implement our proposal as a policy, listing specific criteria under which we will favorably consider waivers of the efficiency standards, as opposed to a blanket rule exempting licensees from those criteria. This approach responds to the concerns raised by Comsearch and FWCC. More specifically, the policy will not “lock in” inefficient usage because licensees will be required to upgrade facilities to use Category A antennas and comply with the efficiency standards if needed to accommodate new FS applicants (or to avoid interference). Furthermore, the criteria we establish will ensure that relief is limited to areas where the use of lower capacity radio equipment will be appropriate. This policy will provide a meaningful opportunity for relief for rural operators. Adopting relief as waiver policy will allow us to consider individual circumstances and to gain more information on when relief from the efficiency standards would be appropriate. As we gain more experience with such waiver filings, we may consider refining the criteria or codifying the policy as a Commission rule.
30. Specifically, we adopt a Rural Microwave Flexibility Policy and direct the Wireless Telecommunications Bureau (“Bureau”) to favorably consider waivers of the payload capacity requirements if the applicants demonstrate compliance with the following criteria:
• The interference environment would allow the applicant to use a less stringent Category B antenna (although the applicant could choose to use a higher performance Category A antenna);
• The applicant specifically acknowledges its duty to upgrade to a Category A antenna and come into compliance with the applicable efficiency standard if necessary to resolve an interference conflict with a current or future microwave link pursuant to § 101.115(c);
• The applicant uses equipment that is capable of readily being upgraded to comply with the applicable payload capacity requirement, and provide a certification in its application that its equipment complies with this requirement;
• Each end of the link is located in a rural area (county or equivalent having population density of 100 persons per square mile or less);
• Each end of the link is in a county with a low density of links in the 4, 6, 11, 18, and 23 GHz bands;
• Neither end of the link is contained within a recognized antenna farm; and
• The applicant describes its proposed service and explains how relief from the efficiency standards will facilitate providing that service (
31. By establishing our Rural Microwave Flexibility Policy, we do not intend to restrict licensees' ability to obtain such relief under §§ 1.925 and 1.3 of our rules. We direct the Bureau to carefully consider requests for waiver of the efficiency standards filed under the general waiver standard, consistent with the Commission's duty to take a “hard look” at applications for waiver and consider all relevant factors when determining if a grant of relief is warranted. The Bureau should not reject a waiver showing under the general waiver standard merely because the applicant has not shown all of the factors listed above. We would anticipate that as an applicant demonstrated compliance with more of the factors listed above, that an applicant would be more likely to have made the requisite showing in support of a waiver. We also direct the Bureau to consider other factors in support of a waiver request, if appropriate.
32. We agree with Comsearch and FWCC that licensees who could use Category B antennas but choose to use Category A antennas should not be foreclosed from seeking waiver relief under the waiver policy we establish today because of their voluntary decision to use a higher performance antenna. Accordingly, we clarify that licensees who could use Category B antennas are eligible for relief from the minimum payload capacity requirements, even if they choose to use a Category A antenna, so long as they meet all of the criteria specified in the Rural Microwave Flexibility Policy we adopt today.
33. Our action today will provide major benefits to FS operators in rural areas. Providing relief from the efficiency standards may allow longer path links, which can eliminate the need for intermediate relay stations. As noted above, the cost of operating an intermediate relay station can be up to
35. Commenters generally support FWCC's proposal, primarily on the ground that smart phones and other mobile devices are generating increased data demands for cellular backhaul. Comsearch and US Cellular advise proceeding cautiously because the conventional approach to assigning channels of 30 megahertz bandwidth in the 6 GHz band and of 30 or 40 megahertz in the 11 GHz band has been to follow an adjacent-channel alternating-polarization (“ACAP”) plan. Comsearch states that this kind of cross-polarization is worth up to a 35 dB reduction in interference when compared with the amount of interference that a signal on the same polarization would cause. If we allow 60 or 80 megahertz channels to be assigned on a single license, it becomes harder to maintain the ACAP licensing plan, particularly when the wider channels are overlaid on existing 30 or 40 megahertz channels. Ultimately, however, in light of the potential cost savings, Comsearch supports allowing wider channels in the 6 and 11 GHz bands “subject to appropriate safeguards.”
36. In response to FWCC's petition for rulemaking, NSMA suggested that the Commission should consider: (1) “Requiring a showing of necessity and availability for applications planning use of more than one or two 60/80 MHz wide channels on any one path”; (2) designating certain slots as “preferred” slots for wider bandwidth channels (
37. We find that allowing 60 megahertz and 80 megahertz channels in the 6 GHz and 11 GHz bands, respectively, would serve the public interest by allowing backhaul operators to handle more capacity and offer faster data rates. In light of the explosive growth in demand for broadband services, we believe it is important to provide operators with the capability to offer faster services wherever possible. Allowing wider channels can also result in more efficient spectrum utilization.
38. The only concern, which was raised by Comsearch and US Cellular, was whether wider channels would be consistent with assigning channels using ACAP. Neither of those parties opposes allowing wider channels, however, so long as appropriate safeguards are instituted against warehousing and inefficient use of spectrum. Commenting parties support the conditions suggested by NSMA. After reviewing the conditions, we will adopt NSMA's suggestion that wideband channels be assigned by preference to the highest available channels in the relevant bands, except where such a choice would impede the efficiency of local frequency coordination efforts. We also adopt today a broader revision of our payload efficiency rules to apply uniform bits-per-second-per-Hertz requirements across multiple bands and bandwidths. Together, we believe those actions will ensure that the 6 and 11 GHz bands are used efficiently while allowing licensees to benefit from wider channels.
39. To protect receivers on geostationary satellites from the potential for interference from FS transmitters, § 101.145 of the Commission's rules requires a waiver filing for: (1) FS transmitters in the 2655-2690 MHz and 5925-7075 MHz bands with an antenna aimed within 2° of the geostationary arc; and (2) FS transmitters in the 12700-13250 MHz range with an antenna aimed within 1.5° of the geostationary arc. To be approved, a waiver request must show, among other factors, that the transmitter EIRP is below listed limits. In contrast, Article 21 of the ITU Radio Regulations places the 2° restriction on the pointing azimuth of antennas of FS transmitters in the 1-10 GHz band only if the EIRP is greater than 35 dBW, and the 1.5° restriction on the azimuth of antennas in the 10-15 GHz band only if the EIRP is greater than 45 dBW.
41. We adopt the proposal to require that a waiver filing be necessary for FS facilities pointing near the geostationary arc only if the FS station's EIRP is greater than the values listed in the ITU Radio Regulations. As noted in the
42. We do not change the requirement that FS facilities protect previously authorized satellite facilities. Nor do we limit the right of satellite licensees to file petitions to deny or informal objections against FS facilities that they believe would cause interference to their facilities. The only change from the viewpoint of satellite providers is that FS operators proposing power below the limits contained in ITU regulations will now be able to operate pursuant to conditional authority.
43. Sirius XM Radio, Inc. (Sirius XM) is the only commenter to oppose the proposed change. Sirius XM operates feeder links in the 7025-7075 MHz band to uplink its digital radio transmissions to its satellites. It also has telemetry, tracking and control links in that band. Sirius XM expresses concern that, even if no single FS transmitter were to interfere with one of its satellites under the proposed rule change, several FS transmitters together might do so. On that basis, Sirius XM urges the Commission to establish a numeric limit on the aggregate amount of interference that FS transmitters impinge upon the geostationary satellite arc. In reply, Comsearch provides a detailed technical analysis demonstrating that it would be extremely rare for terrestrial microwave antennas in this country to be directed towards either of Sirius XM's satellite positions.
44. Comsearch's showing that there are currently only three microwave antennas in this country pointed toward one of Sirius XM's satellites demonstrates that the aggregate incremental effect of such multiple exposures is likely to be quite low. While the Commission is prepared to consider showings based on aggregate interference in appropriate circumstances, we decline to adopt Sirius XM's proposal at this time.
45. We find that reducing the circumstances under which FS operators must seek waivers when pointing towards the geostationary arc will produce substantial benefits. Each private FS applicant must pay an application fee of $180 when seeking a waiver. In 2011, we granted 275 applications requesting a waiver of § 101.145 of the Commission's rules where the EIRP was below the limits contained in the ITU Radio Regulations and the applicant had to pay a waiver fee. The total application costs associated with those waivers would be $49,500. Furthermore, each applicant must prepare a waiver exhibit at additional expense. Furthermore, every time a waiver is requested, the applicant cannot commence service until the waiver and applications are granted. While the cost of such delays cannot be quantified based on this record, it is apparent that such delays may be costly to FS providers and their customers. On the other hand, we find that the potential for increased interference or other costs would be minimal from this action. Accordingly, we find that the benefits of the Commission's actions outweigh the costs.
46. In the
47. The National Association of Broadcasters (NAB) and the Society of Broadcast Engineers, Inc. (SBE) contend that the “introduction of new wireless backhaul operations would be incompatible with effective, unpredictable itinerant newsgathering and news reporting, and it would disserve the public if ENG services at the scene of breaking news were undermined by interference concerns caused by the presence of nearby wireless backhaul operations.” NAB and SBE are also concerned that it would not be feasible to mix the formal coordination process used by FS applicants with the more informal coordination process used by broadcasters, because FS applicants do not have the same incentives as broadcasters to accommodate the needs of TV pick-up operations.
48. We decline to adopt FWCC's proposal to permit FS operations in channels adjacent to BAS/CARS operations at this time, for three reasons. First, as a technical matter, microwave signals that are being transmitted on adjacent channels can interfere with each other under some circumstances and, for that reason, require frequency coordination. Second, as discussed in the
49. In comments filed during an earlier phase of this proceeding, EIBASS asked the Commission to prohibit newcomer Private Operational Fixed Service (POFS) stations in the 7 and 13 GHz bands from degrading the noise threshold of any existing electronic newsgathering-receive only (ENG-RO) site by more than 0.5 dB, citing as precedent the Commission's decision to apply that standard to Department of Defense uplinks when determining whether or not they are providing adequate protection to ENG-RO sites in the 2 GHz band. The
50. EIBASS's proposal is unnecessary because we are upholding the Commission's prior decision to prohibit the paths of FS stations operating in the 7 and 13 GHz bands from crossing the
51. FWCC notes that the
52. Section 101.141(a)(3) of our rules applies minimum payload capacities to digital microwave transmitters operating in the 11 GHz band, depending upon their bandwidths. We agree with FWCC that the same standards should be applied to the 13 GHz band. Our decision above adopting the proposal in the
54. We deny the Cambium Petition because the benefits of allowing 50 megahertz channels in the 7 GHz band appear to be quite limited and because operators needing wider channels have alternatives. If we allowed 50 megahertz channels in the 7 GHz band, there would only be two channel pairs available in the 7 GHz band. Allowing 50 megahertz channels could limit the availability of FS spectrum for other operators who need narrower channels. Furthermore, operators who need 50 megahertz or wider channels have alternative options available. Today, we are allowing 60 megahertz channels in the 6 GHz band and 80 megahertz channels in the 11 GHz band. For shorter paths, 50 megahertz channels are available in the 18 GHz and 23 GHz bands. Under those circumstances, we believe the better use of the 7 GHz band would be to accommodate narrower band operations. We therefore deny the Cambium Petition.
55. The “final link rule” prohibited broadcasters from using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of program material to broadcast stations. Concurrent with the Commission's decision to allow FS to share in the 7 and 13 GHz BAS and CARS bands, the
56. In a petition for reconsideration, FWCC argues that the final link rule should only be eliminated in areas where the Fixed Service can use the 7 or 13 GHz bands. FWCC argues that a key rationale for the change was “sharing of spectrum the other way”—i.e., a
57. In the
58. The Commission's action maximized the ability of both FS operators and broadcasters to use the 7 and 13 GHz bands. While it is true that the Commission did not make those bands available for FS use everywhere, that decision was based on the fact that fixed links and ENG operations are different and difficult to coordinate with each other. In contrast, there is no technical reason why broadcasters, cable operators and part 101 FS operators cannot share the same spectrum when transmitting microwave signals between fixed locations.
59. The Commission's actions maximized the amount of spectrum available to both FS licensees and broadcasters. Furthermore, FWCC does not allege any harm from eliminating the final link rule; and therefore, the Commission's conclusion that there would be significant benefits and no costs to eliminate the final link rule remains unchanged. We therefore deny FWCC's Petition on this issue.
60. In reply comments to the
61. The Commission rejected NSMA's request in the
62. In a petition for reconsideration of the
63. WCAI argues that standards currently applicable to fixed point-to-point services, which require a certain number of links based on population, do not in fact promote service to the public because it requires operators to either build uneconomic links in the absence of demand for backhaul services or lose their licenses. According to WCAI, the standards create “substantial investor uncertainty about the amount of capital required to preserve a license in the millimeter wave bands.” WCAI asks the Commission to adopt an “offer-based” standard that would “require only that an area-wide millimeter wave band licensee offer FP2P service or spectrum leases on commercially reasonable terms and conditions to commercial or government fixed or mobile telephony/broadband service providers or to the licensee's internal network planners.” FWCC and Mary J. Kuiken support WCAI's Petition.
64. WCAI has filed its substantial service proposal for wireless backhaul in WT Docket No. 10-112 and we will consider it in that proceeding, consistent with WCAI's request. The
65. In this
66. FWCC asks that the Commission authorize smaller antennas in the 71-76 and 81-86 GHz bands. We decline to initiate a rulemaking because we do not believe that FWCC has provided sufficient information to justify further action at this time in the context of this proceeding. The current antenna specifications for those bands were adopted after a detailed discussion of the tradeoffs involved. FWCC has not provided sufficient information to demonstrate that smaller antennas could be allowed without increasing interference. Our action today is without prejudice to consideration of a more detailed submission on this issue.
67. EIBASS, which supports the
68. Comsearch and FWCC ask the Commission to streamline application processing when applicants intend to use adaptive modulation by allowing adaptive modulation frequencies to be filed as a single row, as opposed to requiring each combination of modulation, capacity, bandwidth, and transmitter power to be licensed individually. No rule change is required to implement this change, and Bureau staff has started the process of modifying the Universal Licensing System to allow this change.
69. Comsearch and FWCC ask that the Commission eliminate the provision in the rules that allows operation of low power, limited coverage systems in the 23 GHz band because the rules are allegedly unnecessary and allow the use of inefficient antennas. According to Comsearch, that provision was used in the past for low cost analog video systems for purposes such as surveillance. Comsearch describes such systems as “outmoded” and claims to be unaware of any current usage of such systems. The frequencies in question are particularly important and most used in the 23 GHz band because they are available for conditional authority under § 101.31(b) of the Commission's rules. Clearwire also asks the Commission to allow licensees to aggregate channels in the 18 GHz and 23 GHz bands to allow 80 megahertz, 100 megahertz, 120 megahertz, or 150 megahertz channels.
70. We believe these requests should be considered together with other filings relating to the 23 GHz band and therefore defer consideration of them.
71. We recognize that there are other pending matters and proceedings relating to wireless backhaul that are not addressed in this item. Those matters and proceedings include: (1) A petition for rulemaking asking that the 7125-8500 MHz band be allocated for non-federal use and allotted for FS use, (2) a request made in this proceeding to revise the Commission's policy of allowing a satellite earth station to coordinate for the full 360-degree azimuth range of the earth station even when it is communicating with only one satellite in a limited segment of the band, and (3) a petition for rulemaking asking that the Commission establish service rules for FS use in the 42-42.5 GHz band. We defer consideration of these issues and will address them separately or in future orders in this proceeding.
72. This document contains an information collection requirement subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 104-13. It will be submitted to the Office of Management and Budget (OMB) for review under section 3507 of the PRA. Prior to submission to OMB, the Commission will publish a notice in the
73. As required by the Regulatory Flexibility Act of 1980, as amended (RFA), we incorporated an Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on a substantial number of small entities by the policies and rules proposed in the
