Broadband Communities Summit Reprises Age-Old Question About Fiber Versus Wireless Networks

September 29, 2020 — A panel of experts with experience deploying both fiber and wireless networks weighed the pros and cons of each technology during a virtual conversation on Thursday streamed as part of the Broadband Communities 2020 Virtual Summit.
The panelists recognized that there are benefits and shortcomings to each technology. Both fiber and wireless networks will be required to close the digital divide, they said.
“Using the right tool for the job” was a common refrain during the discussion.
“Fiber needs wireless and wireless needs fiber,” said Nathan Stooke, CEO of the Wisper wireless internet service provider in Illinois. He said it may not be beneficial to spend a great deal of time on the age-old question of “fiber or wireless,” although the panel still engaged in a lively discussion on the topic.
Mike McGannon, vice president at Engineering Associates, laid out the case for fiber to the home deployments. He said “fiber requires high capital expenditure and is slow to deploy, but has a low operational expense and holds its value over time. The payback on a fiber network is easily realized in five to ten years.”
McGannon noted that fiber networks are “more likely to offer symmetrical speeds and provide higher latency, which is required by smart cities and internet of things technology.”
“Fiber is more resilient when faced with environmental disruptions than wireless networks,” he said, adding that fiber networks are “estimated to have a 30 to 50-year lifespan, which no other technology can compete with.”
In defense of wireless networks, Brett Glass, founder of Lariat.net, retorted that “wireless has a low capex and is super-fast to deploy.” Yet he also noted the downsides to maintaining wireless networks, saying “they have higher operational expenses and offer speeds nowhere near what fiber is capable of offering.”
But Glass maintained that in some places, and during some points in time, wireless remains the better option.
He detailed a build conducted in a town where only five people lived per square mile in North Dakota, saying it was the financially the smartest option.
Glass further urged that wireless networks have been crucial during the coronavirus pandemic as many have rushed to expand their networks to serve the unserved, as quickly as possible.
While wireless networks allow for broadband to reach consumers sooner, “the rising demand for fiber” and symmetrical upload and download speeds cannot be ignored, said Carroll Faulkner, president and CEO of Digital Fields. Faulkner upheld that “the competitive landscape is trending towards fiber.”
Spectrum
Industry Dissent on Whether Spectrum Sharing is Sustainable
Experts disagree on the capabilities of spectrum sharing, particularly the CBRM model.

WASHINGTON, March 22, 2023 – Industry leaders disagreed on the capabilities of spectrum sharing and its future in the United States at a Federal Communications Bar Association event Wednesday.
Dynamic spectrum sharing – a technology that allows for 4G, LTE, and 5G wireless to be used in the same frequency bands – is essential to a successful national spectrum strategy, said Jennifer McCarthy of Federated Wireless.
Establishing a combination of access points for one frequency band can open its availability for all prospective users, she continued, touting the success of the Citizens Broadband Radio Service established by the Federal Communications Commission in 2012.
CBRS is the spectrum in the 3.5 GHz to 3.7 GHz band which is shared through a three-tiered framework. Access to the spectrum is managed by a dynamic spectrum access system where incumbent users have protected access, priority access users enter through competitive auction, and general authorized access is given to a broad pool of users when not in use by others.
Representative of T-Mobile, John Hunter, disagreed, claiming that dynamic spectrum sharing means there is less power available for technologies, particularly on higher frequencies that don’t propagate very far despite power disparities. As such, deploying the CBRS framework at scale across the country is not cost-feasible, he said.
We should not conclude to share just for the sake of sharing, he said, particularly because it will decrease utility of the band so much that it will decline quality of networks down the line. “In many cases, sharing just outright won’t work,” said Hunter.
Colleen King, vice president of regulatory affairs at Charter Communications, pushed against the argument that dynamic sharing’s lower power will stop providers from providing great service, claiming that it instead allows for more carriers to provide great service. In fact, the CBRS auction had 228 winning bids, 10 times the amount of other spectrum auctions, she said.
The FCC’s Communications Marketplace Report showed that in one market where Verizon is using the CBRS framework, the company is providing “much faster speeds” than its other markets, King cited. Charter will use the CBRS system for its spectrum uses, she said.
Panelists nevertheless agreed on the importance of maintaining US leadership in the spectrum space by developing a national spectrum strategy to address sharing issues.
The panel followed considerable debate over spectrum allocation, sharing, and expansion. Earlier this week, industry leaders suggested that the allocation process be updated in preparation for future disputes. Additionally, debate continues over whether 5G operations can be shared on the 12 GHz spectrum with satellite service providers.
Broadband Mapping & Data
Association Says FCC Not Budging on Identifying Anchor Institutions on Broadband Map
SHLB said FCC officials recommended a workaround that risked penalties.

WASHINGTON, March 22, 2023 – An association representing anchor institutions said in a letter Wednesday that officials from the Federal Communications Commission conveyed that they will not be changing the methodology that excludes schools and libraries from the broadband map and instead recommended a “work around” that the group said could risk penalties.
The Schools, Health and Libraries Broadband Coalition has repeatedly told the FCC that its broadband map incorrectly leaves out anchor institutions because they are categorized as non-broadband serviceable locations by virtue of the fact that they are treated as businesses that purchase commercial service rather than subscribers to “mass-market broadband internet access service,” which is what the FCC maps. SHLB has said this means institutions may not be able to get enhanced connectivity.
While SHLB has said that many small and rural libraries and other institutions subscribe to mass market service, it said in meeting notes from a Monday rendezvous with officials that the commission is “locked into” their current methodology and even recommended a “work-around” that the association said risked penalties.
According to SHLB, officials said the institutions could challenge their status on the map by representing that “they are not anchor institutions in order to change their designation.
“This recommendation is not feasible,” SHLB said. “Anchor institutions are not about to risk penalties by mis-representing themselves in such a way.”
The map, which has been extensively challenged by local governments and is updated every six months, is relied on to provide the most accurate picture of connectivity in the country and to assist federal agencies in divvying out public money. In fact, the National Telecommunications and Information Administration will use the map to determine how much each state will get from tis $42.5 billion Broadband Equity, Access and Deployment Program by June 30.
SHLB said it commissioned a study that found the “vast majority” of 200 libraries on the FCC map were “grayed out” as not broadband serviceable locations.
“If states base their funding decisions on the Map, they will not be able to provide funding to ensure that anchor institutions receive gigabit level service as called for” in the BEAD program, SHLB said in the letter.
The association also said that information presented to it by the FCC during the meeting suggests the map “significantly overstates the areas that are served.”

David Strauss: How State Broadband Offices Will Score BEAD Applications
Fiber, coax and fixed wireless network plans dependent on BEAD funding demand scrutiny.

Given the vital ways in which access to broadband enables America, adequate Internet for all is a necessary and overdue undertaking. To help close the digital divide, the Infrastructure Investment and Jobs Act includes $42.5 billion in Broadband Equity, Access and Deployment funding for the last mile. Add to this the estimated level of subgrantee matching funds and the total last mile figure rises to $64 billon, according to the BEAD Funding Allocation and Project Award Framework from ACA Connects and Cartesian.
The federal funds will be disbursed by the Department of Commerce’s National Telecommunications and Information Administration to the State Broadband Offices who will then award subgrants to service providers. On June 30, each state will find out their allocation amount. By 2024, the states will establish a competitive subgrantee process to start selecting applicants and distributing funds.
A critical element of the selection process is the methodology for scoring the technical merits of each subgrantee and their proposal. Specific assessment criteria to be used by each state are not yet set. However, the subgrantee’s network must be built to meet these key performance and technical requirements:
- Speeds of at least 100 Megabits per second (Mbps) download and 20 Mbps upload
- Latency low enough for “reasonably foreseeable, real-time interactive applications”
- No more than 48 hours of outage a year
- Regular conduit access points for fiber projects
- Begin providing service within four years of subgrant date
What level of scrutiny will each state apply in evaluating the technical merits of the applicants and their plans?
Based on our conversations with a number of state broadband leaders, the answers could be as varied as the number of states. For example, some states intend to rigorously judge each applicant’s technical capability, network design and project readiness. In contrast, another state believes that a deep upfront assessment is not needed because the service provider will not receive funds until certain operational milestones are met. Upon completion, an audit of the network’s performance could be implemented.
We, at Broadband Success Partners, are a bit biased about the level of technical scrutiny we think the states should apply. Having assessed over 50 operating and planned networks for private sector clients, we appreciate the importance of a thorough technical assessment. Our network analyses, management interviews and physical inspections have yielded a valuable number of dos and don’ts. By category, below are some of the critical issues we’ve identified.
Network Planning & Design
- Inadequate architecture, lacking needed redundancy
- Insufficient network as-built diagrams and documentation
- Limited available fiber with many segments lacking spares
Network Construction
- Unprotected, single leased circuit connecting cities to network backbone
- Limited daisy-chained bandwidth paths on backhaul network
- Lack of aerial slack storage, increasing repair time and complexity
Network Management & Performance
- Significant optical ground wire plant, increasing potential maintenance cost
- Internet circuit nearing capacity
- Insufficient IPv4 address inventory for planned growth
Equipment
- Obsolete passive optical network equipment
- Risky use of indoor optical network terminals in outdoor enclosures
- Sloppy, untraceable wiring
Technical Service / Network Operations Center
- Technical staff too lean
- High labor rate for fiber placement
- Insufficient NOC functionality
While the problems we uncover do not always raise to the level of a red flag, it happens often enough to justify this exercise. Our clients who invest their own capital in these networks certainly think so. The same should hold true for networks funded with taxpayer money. Fiber, coax and fixed wireless network plans dependent on BEAD funding demand serious scrutiny.
