Re: Rural Broadband Strategy (GN Docket No.
09-29)
Dear Ms. Dortch:
The
New America Foundation (NAF) submits these brief ex parte comments in response to the Commission's public notice seeking comment on Congress's
directive in the Food, Conservation, and Energy Act of 2008 (2008 Farm Bill)
that the Chairman of the Commission develop, in consultation with the Secretary
of the Department of Agriculture, a comprehensive rural broadband
strategy. We are pleased to see the
Commission is moving forward with this important work. Broadband is the highway of the 21st
century for small towns and rural communities; the vital connection to the
broader nation and increasingly the global economy. It is essential to
promoting economic growth in rural communities and providing residents with
access to quality education and healthcare through telehealth and distance learning
services.
As
the Commission is well aware, rural communities across the country continue to
have little or no access to high speed broadband, with many residents and
businesses still relying upon dial-up modems as their primary connection to the
Internet. Deploying broadband in rural
areas remains a substantial challenge. Build-out costs are often substantially higher
and rural networks remain less profitable than their urban and suburban
counterparts. Adding to these challenges, cost-effective wireless deployment by
local and smaller broadband providers (and potential providers) is limited by
often overly-expensive access to public spectrum and both wired and wireless rural
providers are increasingly burdened with escalating costs for middle-mile
access and backbone transport. Given
these challenges, it is critical for the Commission to develop policy solutions
that focus both on lowering build-out costs for rural deployments and reducing operational
costs for these networks. To that end, NAF recommends the Commission consider the following
policy proposals to encourage greater rural deployment of broadband and
sustainable rural networks.
I. Encourage Greater Wireless Broadband
Deployment through Increased Access to
Spectrum
Section 6112(a)(1)(C) of the 2008 Farm Act requires
the Commission to "address both short- and long-term needs assessments and
solutions for rapid build-out of rural broadband solutions."[1] Wireless remains the most cost-effective and
rapid means to bring broadband access to rural residents. Already, thousands of locally-grown Wireless
Internet Service Providers (WISPs), Rural ILECs, public utilities, NGO's and
local governments are utilizing wireless technology and unlicensed spectrum to bring
wireless broadband to un-served and underserved rural areas across the country. A substantial obstacle for these small and
local providers to expand and scale-up their networks is access to additional spectrum.
Spectrum is the building block for wireless
broadband. While rural provider access
to licensed spectrum is scarce, unused spectrum capacity in rural areas is
abundant. At any given time and
location, the vast majority of our nation's radio frequency spectrum is unused
or substantially underutilized, particularly in rural areas. Recent spectrum occupancy studies by the
Shared Spectrum Company and funded by the National Science Foundation, have demonstrated
in a mix of urban, suburban and rural areas that large swaths of valuable
spectrum are vacant or unused for the majority of the time.[2] For example, the average spectrum use in
rural Limestone, Maine
was just 1.7 percent.[3]
The highest occupancy rate on the prime
beachfront spectrum below 3 GHz was just 13 percent in New York City, while the average across
locations studied was just 6 percent. Across the country, this underutilized
spectrum represents enormous untapped capacity for rural broadband.
The Commission has taken several important
steps to expand access to spectrum for wireless broadband and to encourage more
efficient and intensive use through spectrum sharing -- including its most recent decision to
approve unlicensed "smart radio" access to vacant channels in the TV band, as
well as the "licensing lite" approach in 3.65 GHz and unlicensed access in 2.4
and 5 GHz, which have been essential to spurring wireless broadband deployment in
rural areas by small WISPs, local governments and non-profit operators. Given the success of these open and publicly
available spectrum bands, NAF encourages the Commission to continue to look for
opportunities to lower barriers to spectrum access by increasing the amount of
publicly available spectrum and encouraging greater dynamic spectrum sharing.
Broadband
Mapping Should Include a Mapping of Public Spectrum Capability
As
part of this effort, NAF recommends the Commission perform an Inventory of the Airwaves that maps how
our public spectrum resource is being utilized or underutilized in various
bands. The Commission could draw upon funding
from the American Recovery and Reinvestment Act (ARRA) of 2009, allocated for
developing and maintaining "a comprehensive nationwide inventory map of existing broadband service capability [italics
added]."[4] Spectrum is at the core of wireless broadband
service capability and we believe it would be in the public interest to have a
clear and transparent mapping of those capabilities.
The
Commission and the public need to have a more complete, comprehensive inventory
of what frequencies are actually in
use, for what purpose, with what technology, at what locations, frequencies and
times. Both government and private
sector assignments and uses should be included in the map, with NTIA and the
entire administration an active partner in this effort. With ARRA or other funding, actual spectrum
use measurements in a large and regionally-diverse sampling of markets should
be part of the Commission's broadband mapping exercise.
Spectrum
mapping would help facilitate expanded access to rural broadband providers in
at least three ways:
-
First, more complete and transparent
frequency-by-location data online will improve the functioning of secondary
markets for spectrum license transfers and leasing.
- Second, it will provide information on what will
be required to clear some heavily underutilized bands, so that they can be
reassigned for commercial use.
- Third, it will reveal the far greater number of
frequency bands that could be made available for opportunistic access in
discrete geographic areas, at certain times of day or year, or at certain
altitudes or directions of arrival (azimuth, elevation).
We
believe that rural areas will be the most likely beneficiaries of a mapping of the
U.S.
spectrum capabilities. It will quickly
become clear that particular frequency bands are either completely unused or grossly
underutilized in particular rural markets.
This could provide the Commission or Congress with the information it
needs to reallocate or at least to open these frequencies for non-interfering
use by rural broadband providers. One
promising mechanism for this will be the TV Bands Database, which the
Commission's Office of Engineering and Technology will certify as reliable as a
geo-location lookup service allowing devices on the vacant TV channels to do
real-time checks of channel availability in discrete geographic locations. Additional frequency bands could be added
over time to the database, enriching the spectrum infrastructure for rural
broadband providers and consumers alike.
TV
White Space Rules Should Allow Variable Power for Rural Broadband
NAF also
believes it is vital for the Commission to continue to refine, improve, and
expand upon its rules for spectrum sharing and cognitive or "smart radio"
technology that promise to increase broadband access and to encourage continued
wireless innovation. The Commission's Second
Report & Order adopted last November 4, (Docket 04-186) granting unlicensed
access to vacant spectrum ("white spaces") in the TV band was a tremendous step
forward. However, in its effort to
address the objections of those opposed to any use of the broadcast white
spaces, the Commission adopted overly conservative rules that may limit the
potential of TV band devices (TVBDs) to increase broadband in rural areas.
The
Commission placed a unitary power limit of fixed and mobile TVBDs to protect
incumbent broadcasters, even in rural areas where the vast majority of TV band
is currently unused. As the Public
Interest Spectrum Coalition (PISC) noted in its Petition for Reconsideration in
the Commission's white spaces proceeding, "[t]his limitation is clearly
contrary to the clear Congressional and public interest in promoting more affordable
wireless broad deployment in rural areas where commercial and non-commercial
Wireless Internet Service Providers (WISPs) could use this fallow white space
spectrum to operate at power levels substantially above 4 watts EIRP -- and do
so without any risk of harmful interference to TV reception in areas where
there are four, five, six or even more consecutive unassigned and available TV
white space channels."[5]
In the media market surrounding Pierre, South Dakota,
there are no licensed TV stations above channel 39. A rural WISP could potentially operate a
high-capacity and higher-power broadband service while maintaining a buffer of
three or four empty channels (18-24 MHz guard band) between its service and any
licensed incumbent service. As the Commission's
Order acknowledged "there are advantages, such as reduced infrastructure costs
and increased range, to operation of unlicensed TVBDs at even higher power
levels." Yet, although recognizing the
advantages of variable power limits, the Commission declined at this time to
permit fixed TVBDs to operate at power levels greater than 4 watts EIRP
regardless of proximity to incumbent services -- and instead opted to "further
explore in a separate Notice of Inquiry whether higher powered unlicensed
operation might be accommodated in the TV white spaces in rural areas."[6] While the Commission must guard against reasonable risks of
harmful interference, it should strike a proper balance that furthers the goal
of encouraging broadband deployment.
The Commission has determined that the TV bands database
will be a reliable means of identifying and operating in a channel immediately
adjacent to a television station, or at even higher power with a one channel
separation (n+1). The same database can therefore reliably report that a TVBD
can operate with a n+2, or n+4, or even greater separation from a licensed
service in certain geographic locations -- and hence can operate at a higher
power level without any increased risk of harmful interference. For the same reason, the Commission should
also permit mobile devices to operate at higher and variable power when
separation distances permit.
The
Commission should continue to look for additional opportunities to expand
"smart radio" devices, such as those authorized in white spaces proceeding, to
operate in other underutilized spectrum bands.
This type of technology will continue to promote innovation in spectrum
use and efficiency, while also leading to more reliable and faster wireless networks.
Research is ongoing to develop wireless devices that can dynamically select available
frequencies that will provide for the greatest throughput -- allowing wireless
devices and networks to adjust to the unique RF environment of an area.[7] The key to the continued development of this
advanced wireless technology and other related technologies are access to a
variety of spectrum bands. By focusing
on increasing spectrum sharing and smart radio technology the Commission can help
to expand wireless broadband access while also promoting the U.S. as a global leader in wireless
technology and innovation.
II.
Increase Access to High-Speed Open
Access and Wholesale Middle-Mile Fiber
Infrastructures in Rural Areas to Promote Sustainable and Scalable Networks
A
great deal of the discussion on improving rural broadband access in the U.S. has
focused on last-mile issues, connecting the residences and businesses in a
local community. While this remains a difficult challenge, another key
obstacle to universal high-speed broadband access is the connection of those
last-mile networks to the Internet backbone. No community or network is
an island; and increasingly access to the high-speed middle-mile links that
carry Internet traffic to the backbone, and the escalating costs associated
with transporting traffic among networks, have become fundamental barriers to
spreading connectivity, promoting broadband competition, improving speeds and
lowering prices.
The lack of middle-mile
infrastructure is a considerable problem for existing rural ISPs and a
formidable obstacle to building sustainable rural broadband networks. The
typical rural ISP is 91 miles from its primary backbone Internet connection and
faces considerable costs to transport traffic to and from the backbone.[8] Although prices per megabit have come down in
some instances, total capacity costs are increasing much faster than the razor
thin profit margins of many rural ILECs and WISPs. As network usage increases,
small rural broadband providers are buying more and more capacity to handle the
increased traffic. A National Exchange Carrier Association (NECA) report
found that this "increased IP traffic will exacerbate, rather than
ameliorate" the difficulties of these networks since "existing
revenue shortfalls are multiplied as the scale of operations
increases." NECA's sobering conclusion underscores the necessity for
an intervention: "high-speed Internet service may not be sustainable in
many rural areas based on pure economics."[9]
Without a substantial investment to
bring adequate middle-mile fiber connectivity to rural communities, an increase
in the number of interconnection points and routes, and improved competition in
the middle-mile and backbone, rural networks will hit a wall in terms of speed
and pricing as the capacity costs associated with increased traffic to the
backbone will grow faster than profits.
New America
released a paper in January to directly address this problem with a proposal to
leverage future federally-funded surface transportation spending to build-out
high-speed middle-mile fiber infrastructures in rural communities across the
country.[10] The plan called for funding and mandating
the installation of high-capacity, dark fiber bundles along all
federally-subsidized and direct federal highway projects. The Federal Highway Administration (FHA)
estimates that 90 percent of the cost of deploying fiber in public rights of
way along roadways is associated with digging up and repairing the road to
install the buried fiber.[11]
Thus, it is both expedient and significantly cheaper to install conduit
and fiber while a roadway is already being substantially repaired,
reconstructed or built. This "fiber
to the community" approach would provide the essential wholesale fiber
links necessary to facilitate high-speed broadband deployment by incumbents as
well as new broadband providers and substantially benefit both wired and wireless
networks.
In
addition, rural broadband deployment, competition and affordability would also
benefit enormously from a mapping of the public sector fiber networks used by
federal, state and local public agencies nationwide. Dark fiber and/or excess capacity in public
sector fiber networks is broadband capability that is owned by the public and
should be mapped for potential use along as provided in ARRA. Dark fiber and/or excess capacity on the
public sector's own fiber line infrastructure, opened for wholesale access to
any provider -- commercial or non-commercial -- including
non-vertically-integrated cell phone carriers, WISPs, Rural LECs and muni- or
community WiFi networks, could help to substantially increase middle-mile options.
These
may be among many solutions to improve middle-mile access in rural areas. We
strongly encourage the Commission to address the middle-mile and backbone
transport challenges for rural networks in developing a rural broadband strategy. Affordable and
non-discriminatory access to high-speed middle-mile infrastructures and
backbone transport is absolutely critical to promoting sustainable rural
networks and allowing for these networks to scale-up in terms of speeds and
services.
NAF
appreciates the opportunity to submit the above policy recommendations to the
Commission in its effort to develop a rural broadband strategy. We believe they represent essential building
blocks for expanding high-speed broadband to rural communities; benefiting a
wide variety of providers, business models, and broadband solutions, while also
promoting further innovation, competition, and increased speeds and lower
prices.
