A Short History of Wireless Cable

Spectrum offered Chicago competition to larger ON-TV, selling commercial-free movies and sports on scrambled UHF channel 66 (today WGBO-TV).

Long before many Americans had access to cable television, watching premium commercial-free entertainment in the 1970s was only possible in a handful of large cities, where television stations gave up a significant chunk of their broadcast day to services like ON-TV, Spectrum, SelecTV, Prism, Starcase, Preview, VEU, and SuperTV. For around $20 a month, subscribers received a decoder box to watch the encrypted UHF broadcast programming, which consisted of sports, popular movies and adult entertainment. The channels were relatively expensive to receive, suffered from the same reception problems other UHF stations often had in large metropolitan areas, and were frequently pirated by non-paying customers with modified decoder boxes.

With the spread of cable television into large cities, the single channel over-the-air services were doomed, and between 1983-1985,virtually all of their operations closed down, converting to all-free-viewing, usually as an independent or ethnic language television outlet.

But the desire for competition for cable television persisted, and in the mid-1980s the Federal Communications Commission allocated two blocks of frequencies for entertainment video delivery. The FCC earlier allocated part of this channel space to Instructional Television Fixed Services (ITFS) for programming from schools, hospitals, and religious groups, which could use the capacity to transmit programming to different buildings and potentially to viewers at home with the necessary equipment.

Home Box Office got its start broadcasting on microwave frequencies before moving to satellite.

In practice, ITFS channels allocated during the 1970s were underutilized, because running such an operation was often beyond the budgets and technical expertise of many educational institutions. Premium movie entertainment once again drove the technology forward. After signing off at the end of the school day, Home Box Office, Showtime, and The Movie Channel signed on, using microwave technology to distribute their services to area cable systems and some subscribers. As those premium services migrated to satellite distribution beginning in 1975, reallocation for a new kind of “wireless cable TV” became a reality.

Wireless cable (technically known as “multichannel multipoint distribution service”) began in earnest in the late 1980s and early 1990s, with a package of around 32 channels — typically over the air stations, popular cable networks, and one or two premium movie channels. Some operations in smaller cities sought to beam just a channel or two of premium movies or adult entertainment to paying subscribers, the latter at a substantial price premium. Installation costs paid by providers were more affordable than traditional cable television — around $350 for wireless vs. $1,000 for cable television. That made wireless attractive in rural areas where installation costs for cable television could run even higher.

However, it was not too long before wireless cable operators ran into problems with their business models. Obtaining affordable programming was always difficult. Some cable networks, then-owned by large cable systems, either refused to do business with their wireless competitors or charged discriminatory rates to carry their networks. By the time legislative relief arrived, the wireless industry realized they now had a capacity problem. As cable television systems were being upgraded in the 1990s, the number of channels cable customers received quickly grew to 60 or more (with many more to come with the advent of “digital cable”). Wireless cable was stuck with just 32 channels and a then-analog platform. Satellite television was also becoming a larger competitive threat in rural areas, with DirecTV and Dish delivering hundreds of channels.

American Telecasting gave up its wireless cable ventures, under such names as People’s Wireless TV and SuperView in 1997, selling out to companies including Sprint and BellSouth (today AT&T). BellSouth pulled the plug on the services in February, 2001.

Wireless providers simply could not compete with their smaller packages, and most closed down or sold their operations, often to phone companies. The few remaining systems, mostly in rural areas, have typically combined their wireless frequencies with satellite provider partners to deliver television, slow broadband, and IP-based telephone service.

Rebooting Wireless Cable for the 21st Century

By the early-2000’s the Federal Communications Commission proposed a new allocation for a “Multichannel Video and Data Distribution Service” (MVDDS). Designed to share the 12.2-12.7GHz band with Direct Broadcast Satellite (DBS) services DirecTV and Dish, MVDDS was partly envisioned as a potential way to deliver local stations to satellite subscribers over ground-based transmitters. But things have evolved well beyond that concept, especially after both satellite providers began using “spot beams” to deliver local stations to different regions from their existing fleet of orbiting satellites.

MVDDS was ultimately opened up to be either a competing cable television-like service or for wireless broadband, or both. Michael Powell, then-chairman of the FCC during the first term of George W. Bush, said the technology was free to develop as providers saw fit:

What is MVDDS? The short answer is that we do not know.  Its name, Multichannel Video Distribution and Data Service, seems to suggest everything is possible – and perhaps it is.

But the service rules the Commission has adopted do not require MVDDS to provide any particular kind of service – it could be a multichannel video, or data, or digital radio service, or any other permutation on spectrum use.

The Commission was once in the business of requiring spectrum holders to provide a certain type of service.  That approach failed because government is a very bad predictor of technology and markets – both of which move a lot faster than government.  Over the past decade or so, the Commission has adopted more flexible service rules that bound a service based largely on interference limitations and its allocation (fixed or mobile, terrestrial or satellite).  In this Order, we follow that flexible model for MVDDS.

In 2004 and 2005, licenses to operate MVDDS services were opened up for auction, and a handful of companies won the bulk of them: MDS America, which built a 700-channel wireless cable system in the United Arab Emirates, DTV Norwich, an affiliate of cable operator Cablevision, and South.com, which is really satellite provider Dish Network. Another significant winner was Mr. Bruce E. Fox, who wants to partner with other providers to finance and operate MVDDS services.

Cablevision and Fox are the two most active license recipients at the moment.

A Look at Today’s MVDDS Wireless Players

Fox launched Go Long Wireless in Baltimore as a demonstration project. Go Long transmits its signal from the roof of the World Trade Center at the Baltimore Inner Harbor to the Emerging Technology Center, a business incubator site a few miles away. Fox believes the technology is especially suited to multi-dwelling units like apartment complexes and condos. He plans to work with other service providers who will market and bill the service under their own brand names. Fox does not seem to be interested in challenging the marketplace status quo. He does not believe in using MVDDS to provide television service, for example. In Fox’s view, the real money is in broadband and Voice over IP telephone service.

Cablevision’s involvement is more direct-to-consumer. Its Clearband service– now operating under the new brand ‘OMGFAST’ — is now selling up to 50/3Mbps wireless broadband service in the Deerfield Beach, Fla. area. The company has had nothing to say about whether this service is slated to expand, and if it does, Cablevision will not be permitted to operate it in areas where they already provide cable service, due to the FCC’s cross-ownership rules.

OMGFAST originally bundled voice service in its broadband packages, which it sold at different price points: 12Mbps for $39.95 a month, 25Mbps for $59.95 a month, and 50Mbps at $79.95. The company also tested a 50Mbps promotion priced at $29.95 a month for three months, $59.95 ongoing. Today it offers a better deal: $29.95 a month for 50Mbps service as an ongoing rate. (Expect to pay $10 a month more for mandatory equipment rental, and $14.95 a month if you also want voice service.)

Here is a promotional video explaining how Clearband (now OMGFAST) wireless broadband works. (3 minutes)

MVDDS currently delivers broadband with similar constraints cable systems operate under — namely, download speeds are much faster than upload speeds. That is because upstream bandwidth relies on another transmission technology, often WiMAX, in the 3.65 GHz or 5 GHz bands.

The wireless technology is also very “line of sight,” meaning the tower must be within six miles of the subscriber and not blocked by any obstructions. Hills, buildings, even heavy foliage can all block MVDDS signals the same way satellite signals can be blocked (they share the same frequencies).

Most customers end up with an antenna that very much resembles a traditional satellite dish from DirecTV or Dish, mounted on a roof. To maximize available bandwidth, MVDDS uses a configuration similar to cellular systems, with up to 900Mbps of total bandwidth available to each 90-degree narrow beam sector.

Cablevision has MVDDS licenses to serve most large cities in the United States.

The question is, how will license holders ultimately use the technology. Although originally proposed as a competitor to traditional cable or satellite TV, deregulation has left the fate of MVDDS in the hands of the operators.

Some are considering not selling the service to consumers at all, but rather making a market out of providing backhaul connectivity for cell towers. Dish may be interested in using its licenses to offer customers a triple play package of broadband and phone service with its satellite TV package. Nobody seems particularly interested in providing television service over MVDDS, primarily because programmers’ demands for higher carriage payments would cut into revenue.

Even Cablevision isn’t completely sure what it wants to do. Although it currently is trialing broadband and phone service in Florida, the company earlier petitioned the FCC for increased power to establish a more suitable wireless backhaul service it can sell to mobile phone companies.

For the moment, reviews seem relatively positive for the Florida market test. Of course, as more customers pile on a wireless service, the less speed becomes available to each customer. OMGFAST does not appear to be currently concerned, noting it has no usage caps on its service.

The wireless industry is in transition. Increasing capacity also means decreasing the number of customers trying to share a traditional cell tower. The future will bring a combination of shorter-range cellular and Wi-Fi antennas that can sustain traffic loads much easier than overburdened traditional cell towers.

The President’s Council of Advisors on Policy and Technology’s recommendation that the growing demand for wireless spectrum be met by sharing frequencies with the federal government is getting a cold reception from the wireless industry.

AT&T, other wireless operators, and their lobbying trade association have been embarked on a fierce campaign in Washington to free up additional spectrum they can use to meet growing demands for wireless data. Unfortunately, clearing spectrum that can be re-purposed for wireless phone companies requires complicated, and often expensive frequency reassignments as existing users relocate elsewhere. With the federal government holding a large swath of spectrum for the use of a range of public safety, research, and military applications, the best source for new frequencies comes from Washington.

PCAST’s final 200-page report urges the Commerce Department prioritize locating 1000MHz of frequencies that could be re-purposed for private wireless communications. But the council also recommended that frequencies could be more quickly made available by asking wireless telecom companies to share them with existing users.

Today’s “exclusive use” licenses all too often are being underutilized and, in fact, are sometimes used as a valuable investment tool to buy, trade, or sell. Issuing exclusive licenses guarantees that no other players can use those frequencies. That is a valuable tool for wireless companies protecting their market share from potential competitors.

PCAST declared the concept of a “spectrum shortage” to be largely a myth:

Although there is a general perception of spectrum scarcity, most spectrum capacity is not used. An assigned primary user may occupy a band, preventing any other user from gaining access, yet consume only a fraction of the potential spectrum capacity. Unique among natural resources owned by the public, spectrum capacity is infinitely renewable from second to second—that is, any spectrum vacated by one user is immediately available for any other user.

Measurements of actual spectrum use show that less than 20 percent of the capacity of the prime spec­trum bands (below 3.7 GHz) is in use even in the most congested urban areas.

This spectrum inefficiency is not just a problem for the wireless industry, it also afflicts government use as well. But it is a problem that can be solved by modernizing spectrum allocation policy in the United States.

“Exclusive frequency assign­ments should not be interpreted as a reason to preclude other productive uses of spectrum capacity in areas or at times where the primary use is dormant or where underutilized capacity can be shared,” the report concludes.

If implemented, the wireless industry could begin accessing hundreds of megahertz of new spectrum, with the understanding there may be other users sharing certain frequencies in different areas at different times. For example, AT&T could use spectrum assigned to forest rangers in federal parks for wireless data in Manhattan or other urban areas, where neither user will create interference for the other. Verizon could use spectrum allocated for naval communications at seaside ports in land-locked Nebraska, Utah, Kansas, or West Virginia.

The proposal identifies these frequency bands as ideal for shared use between private and government users.

As technology progresses, shared spectrum users will easily afford equipment that dynamically locates open frequencies for communications with little or no interference even if two users are located right next door to each other.

The benefits to taxpayers, governmental users, and private industry are notable:

1. The cost to relocate existing government users to other bands is prohibitively time-consuming, complicated, and expensive. Taxpayers often foot the bill for the frequency changes;
2. Government use of spectrum is not particularly efficient either. Identifying under-utilized spectrum for shared-use can bring pressure to government users to consolidate operations and increase operating efficiency;
3. Private industry gets much faster access to new spectrum, which suddenly becomes plentiful and potentially affordable for new entrants in the wireless marketplace.

Despite the benefits, the wireless industry had a frosty reception to the new report:

Joan Marsh, AT&T Vice President of Federal Regulatory:

“While we are still reviewing the PCAST report, we are encouraged by the sustained interest in exploring ways to free up underutilized government spectrum for mobile Internet use.  However, we are concerned with the report’s primary conclusion that ‘the norm for spectrum use should be sharing, not exclusivity.’  The report fails to recognize the benefits of exclusive use licenses, which are well known.  Those licenses enabled the creation of the mobile Internet and all of the ensuing innovation, investment and job creation that followed.

“While we should be considering all options to meet the country’s spectrum goals, including the sharing of federal spectrum with government users, it is imperative that we clear and reallocate government spectrum where practical.  We fully support the NTIA effort of determining which government bands can be cleared for commercial use, and we look forward to continuing to work with NTIA and other stakeholders to make more spectrum available for American consumers and businesses.”

CTIA – The Wireless Association:

The CTIA is the wireless industry’s lobbying group

“We thank the Administration and PCAST for focusing on the need to make more efficient use of spectrum currently assigned to federal government users. As the PCAST report notes, it is sensible to investigate creative approaches for making federal government spectrum commercially available, including the development of certain sharing capabilities. At the same time, and as Congress recognized in the recently-passed spectrum legislation, the gold standard for deployment of ubiquitous mobile broadband networks remains cleared spectrum.

“Cleared spectrum and an exclusive-use approach has enabled the U.S. wireless industry to invest hundreds of billions of dollars, deploying world-leading mobile broadband networks and resulting in tremendous economic benefits for U.S. consumers and businesses. Not surprisingly, that is the very same approach that has been used by the countries that we compete with in the global marketplace, who have brought hundreds of megahertz of cleared spectrum to market in recent years.

“Policymakers on a bipartisan basis have grasped the importance of making more spectrum available to meet the growing demand for mobile Internet services, and this report highlights a range of forward-looking options, some of which are not yet commercially available, that may be considered to meet this important national goal. We look forward to continuing to work with the Administration, the FCC, NTIA, Congress and other interested parties to increase access to federal government spectrum and to continue to assist our nation in its economic recovery.”

Wireless carriers will continue to lobby Washington lawmakers to leave the current “exclusive use” spectrum policies in place, even if it delays opening up “badly-needed” spectrum for years.

In short, the major players in the wireless industry are hostile to the idea of losing exclusive-use spectrum. That comes as little surprise because shared spectrum cannot be controlled by the wireless industry. Spectrum squatting, where large phone companies or investment groups hang on to unused spectrum either to keep competitors out or as an investment tool until it eventually can be resold at a major profit, is a significant problem in the industry. Wall Street analysts routinely assign value to the spectrum holdings of wireless carriers, whether they are used or not. Since most spectrum is now sold to the industry at “highest bidder wins” auctions, only the largest players are frequently serious contenders. Auctioning off shared spectrum, if practical, will bring lower bids — but could potentially bring new bidders like start-up ventures that have some new ideas on how to use wireless frequencies to compete.

Therefore, it has been in the wireless industry’s best interests to keep the idea of sharing frequencies with other players out of the minds of Washington regulators and legislators. Their technical objections and claims that shared spectrum would somehow destroy innovation and investment ring hollow, and are weak deflections from the more obvious agenda: to maintain their status quo control of wireless frequencies, well-utilized or not.

AT&T and other wireless players will no doubt lobby their case to Washington politicians, many who will rush to the industry’s defense. The shadow argument most likely to be used to defend the current “exclusive use” auction system is the auction proceeds collected by the federal government. Billions have been raised from past auctions, and shared use frequencies would never net that level of return. But PCAST’s report exposes the rest of the story. The cost to reallocate existing users to other frequencies, hand out new radios, raise new antennas and purchase new transmitters is often so costly, the government’s net gain, post-auction, is likely to be minimal.

Abroad, many governments have already adopted shared use, discarding the focus on spectrum earnings and refocusing spectrum allocation on delivering the best bang for the buck — whether that dollar belongs to the consumer, the wireless industry, or the government.

Attempts by AT&T and others to kill PCAST’s recommendations should also be considered proof the industry’s dire claim of a spectrum shortage emergency is vastly overblown. In a true crisis, everyone makes compromises.  That does not appear to be the case here. Congress and regulators should receive that message loud and clear.

NOAA caught this ominous derecho cloud front in La Porte, Ind on June 29. The same storm would later cut power for millions all the way to the eastern seaboard.

A series of severe thunderstorms accompanied by near-hurricane-force winds caused millions of customers in several Mid-Atlantic states to lose power and telecommunications services late Friday, and some are expected to remain without service until at least this coming weekend.

The storm, known as a “derecho,” uprooted trees, which in turn knocked down power lines and caused wind-related damage to buildings from Ohio to West Virginia, Virginia to Maryland, and even into North Carolina.

But the storm also is raising questions about the massive failures in commercial telecommunications systems that left entire 911 emergency response systems offline for days, wireless networks non-operational, cell phone systems overwhelmed, and broadband service, deemed a lower priority by emergency officials, down and offline.

Some of the biggest problems remain in and around the nation’s capital and in the states of West Virginia and Virginia, where inadequate infrastructure proved especially susceptible to the storm’s damaging winds.

D.C., Maryland, and northern Virginia

In northern Virginia, calls to 911 were met by silence over the weekend, thanks to a catastrophic failure of Verizon’s landline network. With primary lines down, Verizon’s backup 911 systems also failed, leaving millions with no access to emergency responders.

Fairfax County officials finally put the word out the best way to summon emergency help was to drive (through streets littered with debris and downed power lines) to the nearest fire or police station for assistance.

“It’s just not OK for the entire 911 system in the region to go down for the period of time that we were out, especially after an enormous emergency where people needed to make those calls the most,” Sharon Bulova, chairman of the Fairfax County Board of Supervisors, told the Associated Press.

Verizon spokesman Harry Mitchell was left flat-footed, promising an investigation into Verizon’s latest 911 failure, and called the storm as damaging as a hurricane. He urged local officials to “move forward” beyond the immediate criticism and help make progress to get service restored.

Many emergency response networks also depend on telecommunications services, including fiber cables, to reach transmission towers for radio dispatch and mobile data terminals. In northern Virginia, the city of Alexandria has been managing to handle emergency dispatch services for several counties.

With power lines down, cable and phone lines often went as well. In those cases, electric utilities have first priority to restore service, and then cable and phone companies can begin repairs of their own.

Since cable operators rely on power companies to supply electricity to their amplifiers and other equipment, Comcast and Cox, which dominate the region, are blaming most of their outages on power disruptions, and promise service will be restored when the power returns.

Verizon’s DSL and FiOS broadband networks were both disrupted by the storm, primarily because of downed lines and power losses.Even wireless networks, which some might suspect would be immune to downed lines, were also seriously affected by the storm. Cell towers connect to the provider’s network through fiber optic and T1 lines, and although backup power generators can maintain a cell tower for days in some cases, backhaul line cuts can leave cell towers useless.

In metro D.C., call completion problems were a problem during the storm and sometime after as local residents turned to cell phones to communicate. Over the weekend, customers in and around Richmond, Va., found Verizon Wireless useless for text messages because of a service disruption. As backup generators ran dry of fuel, some cell towers that survived the initial storm have been shutting down until maintenance crews arrive and refuel.

The harshest criticism has so far escaped phone and cable companies. Instead, local officials and residents remain focused on Pepco, the power utility serving the Washington area. Pepco has learned from previous storms to become a master of lowered expectations, and is promising to do its best to restore power a week or more after the storm was a memory.

West Virginia and western Virginia

The state of West Virginia, and western rural Virginia state, have illustrated what happens when deteriorating infrastructure is asked to withstand winds of up to 100mph. Frontier’s operations in West Virginia were hit especially hard. Landline networks in that state had been allowed to deteriorate for years by former owner Verizon Communications. Frontier had its hands full trying to keep up with repairs, calling in additional staff and trying to maintain landline service in some areas with the help of generators.

That job was made much harder by a rash of generator thefts that impacted the phone company, and local authorities are still looking for those responsible. At least one-third of all central switching offices operated by Frontier in West Virginia remain on generator power as of yesterday. As of July 3, the company reported it has 12,000 repair requests still waiting for action.

It was a similar story in the western half of Virginia where independent phone companies and Verizon were faced with an enormous number of downed trees and power lines, many in rural areas. More than 108,000 Virginia residents are still without power as of this afternoon, and many will not see it restored until the weekend.

Because the derecho swept across a large area encompassing the entire state, it has been difficult for utility crews to respond from unaffected areas to assist in repairs because the damage was so widespread. Logistically, just coordinating repair operations has proved difficult because cell service has been spotty (or networks have been jammed with calls) in some of the worst-affected areas.

“Derechos are nothing to fool with, but still this was not the most serious storm Virginia has ever dealt with, and the impacts on our telecommunications networks seem to indicate they’ve been allowed to fall apart over the last several years,” shares Stop the Cap! reader Edward Klein, who lives near Roanoke. “I think an investigation is needed to make sure utilities are spending enough money to keep these networks in good shape so this kind of thing doesn’t happen everytime a storm sweeps through.”

AT&T is ingratiating itself with both sides of the political divide, as the Democratic National Convention Committee names the company the “official carrier” of the convention.

While that is likely to bring good will for AT&T among convention delegates, politicians, and their families, Charlotte, N.C. residents are also welcoming the major upgrades that are coming with AT&T’s presence at the event.

The phone company is installing at least 50 micro-tower antennas atop light poles in downtown Charlotte, designed to boost capacity for both AT&T’s Wi-Fi and cellular networks. Another 10 mobile cell towers will be in place during the event to accommodate the anticipated 35,000 visitors attending the convention at Time Warner Cable Arena.

Canadians: Get ready for more cell towers in your neighborhood.

Industry Canada’s fuzzy math threatens to allow cell phone companies to erect new cell towers in some of the country’s most scenic areas, which often coincidentally offer the best reception.

Residents in Pontiac, Quebec are learning that first-hand, as Industry Canada approves a controversial proposal from Vidéotron to install an 82-meter cell tower in the middle of a vista that tourist officials use in brochures to promote travel in the Ottawa River region.

It turns out the regulator now only considers an antenna’s base as a factor in determining whether to approve a new cell tower. That base amounts to just one square meter, “too small” by Industry Canada’s standards to conduct an environmental assessment. No matter that the antenna will tower nearly 270 feet into the skyline. Industry Canada is only interested in measuring the three legs of the tower (each leg is evaluated individually, not collectively), and at just one tiny meter, it isn’t worth their time.

That means local residents will have to contend with a new tower 25-stories high. As the Ottawa Citizen puts it, Vidéotron’s tower is smaller in the government’s eye than any pre-fabricated garden shed from Home Depot, which often requires a permit to install.

The new tower will be installed on Hurdman Heights, much to the consternation of area residents and naturalists opposed to its presence, ruining what many call the most scenic place in the region.

The local government of Pontiac has opposed the new Vidéotron tower since it was first announced, but the cable/wireless company pulled an end run around the municipality claiming there was a negotiating impasse and local officials would not meet to work it out, a good enough reason for the regulator to approve the new tower. Pontiac Mayor Eddie McCann says there was no impasse and the local council has been trying hard to reach a deal with the telecommunications company and never cut off talks:
