寬帶神話：市政寬帶規(guī)模是否能很好地滿足美國寬帶需求

1、Broadband Myth Series:Does Municipal Broadband Scale Well to Fit U.S. Needs?DOUG BRAKE AND ALEXANDRA BRUER | JUNE 2021No, local governments generally are not well-suited to providing broadband service. Economic theory suggests city-run broadband would not serve the country well, and previous real-wo

2、rld attempts bear that out with a mixed track record marked by several failures.KEY TAKEAWAYSUnlike traditional utilities that are relatively static, like electricity distribution, broadband is dynamic, requiring consistent investment to keep up with technological change. The private sector can bett

3、er adapt and drive continual improvement.Municipal networks often deploy first in low-cost, high-return business-improvement districts and are necessarily limited in their jurisdiction, making it difficult for regional providers to support areas outside city limits.Municipalities do not support inno

4、vation as well as the private sector does. For example, they do not contribute to standards-setting organizations or invest in R&D.Several municipal networks have failed, and those that remain financially viable often owe their success more to federal subsidies or unique circumstances than to their

5、ownership model.That said, broadband policy should not be ideological or absolutist. If there are areas that private providers are not interested in serving, even with subsidies, then municipalities should be empowered to step in and offer broadband.INTRODUCTIONThe Biden administration has proposed

6、a preference for federal funding of broadband infrastructure provided by municipal or nonprofit operators, thrusting municipal ownership of broadband facilities back into the center of telecommunications policy debates. Any federal broadband infrastructure subsidies should be awarded on an “ownershi

7、p neutral” basis, neither favoring nor penalizing government-provided broadband systems. Municipal broadband does not scale well to serve the country, but should be an available option for connecting areas private firms would otherwise leave genuinely unserved despite infrastructure subsidiesgeneral

8、ly small, widely dispersed towns where private provision is unsustainable even after the initial subsidized infrastructure deployment.For advocates on the left, who would like to see broadband provided as a utility-like service, having the local authority provide Internet service at cost as a public

9、 good is nirvana. There are several problems with this view, however. It ignores the dynamic, evolving nature of broadband. It misunderstands the economics of a high sunk-cost industry with a limited addressable market.And it encourages unfair “cream skimming” wherein municipal providers take the lo

10、west cost, highest revenue customers and leave the others outside of municipal borders for private providers.On the other side of the political spectrum, free-market libertarians also go too far, preferring no government involvement in this market at allindeed many states bar local authorities from

11、providing broadband service, even if they can prove they will do it without unfair subsidies or regulatory advantages. Policymakers should be pragmatic and keep all tools available for bridging the digital divide, but the significant trade-offs of municipal broadband mean it is only appropriate for

12、narrow circumstances.Mandating additional facilities-based, government-owned competitive “overbuilding” would increase national broadband costs with little benefit.Importantly, municipal broadband providers do not invest in innovation the same way the private sector does. Local governments are unlik

13、ely to contribute to standards-setting organizations or develop and patent new technologies or techniques like private broadband firms do.Many municipal advocates seem to think that once supposedly “future-proof” technologies are deployed, there is no more necessary investment or upkeep. True, build

14、ing broadband involves large up-front sunk costs in the trenching of fiber or stringing of cable along poles. But there are also tremendous ongoing expenses to ensuring that even easily upgradable technology actually remains future-proof. If we start to treat broadband as a public utility, such as w

15、ater pipes, sewers, or roads, we are likely to see the same problems develop: deferred investment, congestion, declining quality, and a lack of innovation.Competition from the public sector may, in some circumstances, see incumbents drop prices or marginally raise speeds in response. This dynamic is

16、 regularly lauded by municipal broadband advocates as a sign of progress, but it comes at the cost of long-term investment in both the development of new innovations and the ongoing upkeep and upgrades of existing infrastructure.If the goal is additional competitors to provide more consumer choiceso

17、mething that comes at a cost of duplicate facilitiesthere is still much that local governments can do to lower the barriers to market entry and facilitate low-cost deployment by private firms. Rather than enter the market directly, local authorities should ensure a streamlined process to access righ

18、ts of way and attach to poles, for example. Enabling dynamic competition would best serve consumers in the long term. But mandating additional facilities-based, government-owned competitive “overbuilding” would increase national broadband costs with little benefit. In crafting a national broadband i

19、nfrastructure package, Congress should avoid elevating the role of municipal and nonprofit providers.MUNICIPAL BROADBAND BACKERS OFTEN IGNORE TRADE-OFFSDetermining the appropriate broadband policy and regulations requires an understanding of the series of trade-offs when deciding one pathway over an

20、other. Broadband policy is not simply about access or affordability, but also about investment, competition, and innovation. Policy must seek to develop an appropriate balance that optimizes the multiple facets of broadband to ensure optimal connectivity today and into the future.Broadband Requires

21、Constant InvestmentFuture-proofing broadband is not a one-and-done expense, as it requires constant investment. Deploying, maintaining, and upgrading broadband have costs that go well beyond the initial capital expenditures used to build the network foundation. Broadband providers in the United Stat

22、es averaged expenditures of over $74 billion per year between 2010 and 2019. HYPERLINK l _bookmark0 1 Moreover, data compiled by the Progressive Policy Institute (PPI) highlights how telecom providers are regularly some of the largest investors in capital spending across the country. PPIs 2019 repor

23、t indicates communications and broadband as the number-one industry in capital growth between 2007 and 2017. HYPERLINK l _bookmark1 2 AT&T and Verizon Communications alone contributed $284 billion in capital in the United States between 2011 and 2018. HYPERLINK l _bookmark2 3Consider that in the fir

24、st quarter of 2021 alone, AT&T posted capital expenditures equaling $4 billion, and Comcast posted capital expenditures of $1.9 billion. HYPERLINK l _bookmark3 4 We cannot realistically expect municipal governments, even collectively, to be investing at this level consistently. Broadband is not the

25、type of infrastructure that is future-proof simply as a virtue of the technology initially installed. Even fiber optics will require continual maintenance and upgrades, at least of the electronics, in order to keep pace with changes in technology.If policymakers insist on cities providing broadband

26、like a utility, networks likely will face the same pitfalls of deferred maintenance and underinvestment that burden U.S. roads, bridges, and sewers.An infusion of cash to help build out new networks may allow certain areas to leapfrog to the latest access technology, but networks will still require

27、constant investment and improvements to offer competitive services to consumers. Representative John Curtis (R-UT), who is also the former mayor of Provo, Utah, highlighted this point in a recent hearing, noting that Provos municipal network failed due to its “inability to deal with the fast-changin

28、g nature of broadband and the large capital needs that happen on a recurring basis.” HYPERLINK l _bookmark4 5 He explained that municipalities cannot assume that, because they provide electricity, they can easily provide broadband: “There are dramatic differences between streets, sewers, parks, and,

29、 yes, even municipal power andbroadband deployment.” HYPERLINK l _bookmark5 6 A typical house in America is served by the same street, sewer, and electricity lines as it was when it was built. But the broadband it gets improves on a regular basis.If policymakers treat broadband like a utility, it ma

30、y face pitfalls similar to our sewers and roads: deferred maintenance and underinvestment. HYPERLINK l _bookmark6 7 For example, after the American Recovery and Reinvestment Act (ARRA) of 2009, when a large infusion of funding was dispersed to improveU.S. roadways, “growth in federal spending due to

31、 ARRA was accompanied by a decline in state and local government spending.” HYPERLINK l _bookmark7 8 Within roughly six years, local and state funds returned to their pre-ARRA levels. HYPERLINK l _bookmark8 9 Yet, over a decade later, U.S. roadways received a “D” on the 2021 report card from the Ame

32、rican Society of Civil Engineers. HYPERLINK l _bookmark9 10 Like roadways, fiber will require constant investment to ensure upkeep and evolution.Moreover, the notion that fiber is the only future-proof technology is a myth. Because of technological innovation, cable broadband speeds have dramaticall

33、y increased. Digital subscriber line (DSL) continues to see breakthroughs in throughput, at least over longer distances, with important implications for competition and the economics of legacy networks. Mobile speeds have seen remarkable improvements with breakthroughs in antenna technology, and mor

34、e spectrum is made available for the commercial sectorwith the additional benefit of mobility and wide coverage.To have future-proof broadband, we shouldnt be relying on local governments to install todays best wired technology, whatever the cost. Instead, we should continue to rely on private compe

35、tition to serve the vast majority of the country, driving continued investment and innovation that pushes technology forward.Artificial Competition Can Result in Overbuilding and Lower the Chance of Connectivity in High-Cost AreasDeploying a municipal broadband network in areas where competing netwo

36、rks exist in order togenerate artificial competition results in overbuilding, with taxpayers paying for additional infrastructure where it already exists. Deploying a broadband network requires substantial initial investment. This is a sunk cost that cannot be put to other uses or avoided if a netwo

37、rk loses a customer. As Jonathan Nuechterlein and Howard Shelanski explained in a recent paper, “When one broadband provider loses a household to the other, it loses all revenues associated with that household but saves very little in the form of avoided costs.” HYPERLINK l _bookmark10 11When a new

38、“competitor” in the form of a local government enters a duopoly market, the overall costs of providing the infrastructure to that area go up by roughly 50 percent. And the service base, which any one provider can rely on for revenue goes down from half of the market to a third of the market, assumin

39、g equal market share. The overall system has higher costs with a more fragmented base to recoup those costs, ultimately slowing investment and innovation.When the same amount of revenue is spread across more providers, it makes recovering costs harder, and delaysif not eliminatesplans to provide com

40、petitive upgrades. In theory, municipal providers should have an advantage over incumbents. They often enjoy financially advantageous terms in the bond market, can avoid right-of-way fees, dont pay taxes, and can eschew profits.But in lived reality, the track record of municipal networks is mixed. S

41、ome operate successfully, but many fail, with municipal networks having defaulted on loan obligations, faced lowered city bond ratings, lost track of invested assets, and required additional infusions of taxpayer money. HYPERLINK l _bookmark11 12 When municipalities enter a market, it is only logica

42、l that incumbents will reduce prices in order to maintain market share. HYPERLINK l _bookmark12 13 While lower prices certainly are a gain to consumers in the city in the short term, this comes at a cost in terms of capital available for long-term investment (in the entire service area of the privat

43、e company) and contributions to research and development (R&D) as well as for the financial health of the municipalitys project.Municipal networks often cherry-pick ideal parts of the markets, leaving behind higher-cost areas on the outskirts of town or outside city limits worse off. Initial build-o

44、uts of municipal networks almost always start with city buildings, then deploy to commercial corridors or business improvement districts, before gradually deploying through the rest of the city as finances allow. This certainly makes sense from the municipalitys perspective. Not only does this have

45、the largest productivity gains for the local economy early on, but business and local government customers are also often the best paying and lowest cost to serve, all in one concentrated location. Incumbent private providers regularly serve both high-density areas and their low- density peripheries

46、 because of earlier franchise agreements and other efforts to deploy universal service.There are real trade-offs to municipal networks, especially when considering a larger view of regional or nationalrather than personal or localinterests.Additionally, municipal networks are necessarily limited by

47、jurisdiction. Outside of city limits, private providers are left with the higher-cost, lower-return areas. These more-dispersed areas have already had trouble attracting private investment, and now with a municipality taking significant market share next door, the economics of the region become even

48、 more difficult. This means higher costs and lower revenues from private providers serving large geographic areas.Municipal networks make it more difficult for private operators to invest in regional networks or invest in future innovation. There are real trade-offs to municipal networks, especially

49、 when considering a larger view of regional or nationalrather than personal or localinterests. This kind of cherry-picking might make economic sense for a particular city, but if every city engaged in it, residents in nonincorporated places would face much higher costs for broadband.Broadband Requir

50、es Standards, Innovation, and ExpansionBroadband is continually improving, with constant innovation and new standards developed as technology evolves. CableLabs, for example, provides R&D for cable broadband technologies. HYPERLINK l _bookmark13 14 As part of this research, CableLabs has developed c

51、able standards such as Data Over Cable Service Interface Specification (DOCSIS). This standard continues to evolve, incorporating new developments such as full duplex communications, which will allow up- and downstream traffic to share data channels within the network. HYPERLINK l _bookmark14 15 Mor

52、eover, CableLabs work helps to ensure the interoperability of cable technologies, to include Wi-Fi routers. HYPERLINK l _bookmark15 16 CableLabs is composed of 64 companies, 17 of which are from the United States and whose dues are calculated based on each members cable revenue. HYPERLINK l _bookmar

53、k16 17 It is these private sector companies that help drive forward the standards for broadband to ensure increased optimization and interoperability of technologies.Examples of private sector broadband innovation abound in the copper network planet as well. Bell Labs and its successors contributed

54、to the advent of the asymmetrical digital subscriber line (ADSL). HYPERLINK l _bookmark17 18 Many of the most important innovations in DSL were pioneered by Dr. John Cioffi, who has held positions at Stanford and multiple private firms. HYPERLINK l _bookmark18 19 Innovations led by Cioffi such as ve

55、ctoring and dynamic spectrum management for DSL continue to improve performance of the copper network. G.fast, the latest mainstream DLS standard, allows for gigabit speeds over legacy copper infrastructure over short distances. Current research at Brown University and Stanford, with funding through

56、 a combined National Science Foundation (NSF) grant and industry sponsorship, promises “fiber-like speeds of 10 1000s of Gbps” are possible over current copper infrastructure. HYPERLINK l _bookmark19 20Private sector competition also helps drive breakthroughs in new access technology. A government-b

57、acked utility would be more difficult for a new entrant to displace than would private sector incumbents. Knowing that a municipality can potentially recover costs from taxpayers or otherwise benefit from implicit (or explicit) subsidies considerably diminishes the incentives for innovators to devel

58、op disruptive technology to enter the broadband market. The prospect for taking market share in home broadband connectivity has driven development of 5G home broadband products. Mobile broadband itself continues to improve speeds to the point where it increasingly competes directly with fixed access

59、. HYPERLINK l _bookmark20 21 While as a matter of policy the Information Technology and Innovation Foundation (ITIF) believes everyone should have broadband access in the home that allows for participation in online activities, this can certainly be achieved with mobile access, depending on the form

60、 factor of the devices connected.Satellite access is undergoing rapid, dynamic change. Investments in Low Earth Orbit satellite constellations, such as those being deployed by SpaceX and Amazons Project Kuiper, would likely be diminished if broadband were provided as a local utility.
