The Slow Deployment of 5G

Somebody asked me a few days ago why I write so much about 5G. My response is that I am intrigued by the 5G hype. The major players in the industry have been devoting big dollars to promote a technology that is still mostly vaporware. The most interesting thing about 5G is how politicians, regulators and the public have bought into the hype. I’ve never seen anything like it. I can remember other times when the world was abuzz over a new technology, but this was usually a reaction to an actual technology you could buy like the first laptop computers, the first iPhone and the first iPod.

Anybody that understands our industry knew that it will take a number of years to roll out any major new technology, particularly a wireless technology since wireless behaves differently in the field compared to the lab. We’re only a year past the release of 5G standards, and it’s unrealistic to think those standards could be translated into operation hardware and software systems in such a short time. You only have to look back at the history of 4G, which started as slowly as 5G and which finally had the first fully-compliant 4G cell site late last year.  It’s going to take just as long until we see a fully functional 5G cell site. What we will see, over time, is the incremental introduction of some of the aspects of 5G as they get translated from lab to the field. That rollout is further complicated for cellular use by the timeline needed to get 5G-ready handsets into peoples’ hands.

This blog was prompted by a Verizon announcement that 5G mobile services will be coming to 30 cities later this year. Of course, the announcement was short on details, because those details would probably be embarrassing for Verizon. I would expect that the company will introduce a tiny few aspects of 5G into the cell sites in business districts of major cities and claim that as a 5G roll-out.

What does that a roll-out this year mean for cellular customers? There are not yet any 5G capable cellphones. Both AT&T and Verizon have been working with Samsung to introduce a 5G version of their S10 phone later this year. Verizon has also been reported to be working with Lenovo for a 5G modular upgrade later this year. I’m guessing these phones are going to come with a premium price tag for the early adaptors willing to pay for 5G bragging rights. These phones will only work as 5G from the handful of cell sites with 5G gear – and that will only be for a tiny subset of the 5G specifications. I remember when one of my friends bought one of the first 4G phones and crowed about how it worked in downtown DC. At the time I told him his great performance was because he was probably the only guy using 4G – and sure enough, his performance dropped as others joined the new technology.

On the same day that I saw this Verizon announcement I also saw a prediction by Cisco that only 3% of cellular connections will occur over a 5G network by the end of 2022. This might be the best thing I’ve seen that pops the 5G hype. Even for folks buying the early 5G phones, there will be a dearth of cell sites around the country that will work with 5G for a number of years. Anybody who understands the lifecycle of cellular upgrades agrees with the Cisco timeline. It takes years to work through the cycle of upgrading cell sites, upgrading handsets and then getting those handsets to the public.

The same is true for the other technologies that are also being called 5G. Verizon made a huge splash just a few months ago about introducing 5G broadband using millimeter wave spectrum in four cities. Even at the time of that announcement, it was clear that those radios were not using the 5G standard, and Verizon quietly announced recently that they were ceasing those deployments while they wait for actual 5G technology. Those deployments were actually a beta test of millimeter wave radios, not the start of a rapid nationwide deployment of 5G broadband from poles.

AT&T had an even more ludicrous announcement at the end of 2018 where they announced 5G broadband that involved deployment of WiFi hotspots that were supposedly fed by 5G. However, this was a true phantom product for which they had no pricing and that nobody could order. And since no AT&T cell sites have been upgraded to 5G, one had to wonder how this involved any 5G technology. It’s clear this was technology roll-out by press release only so that they could have the bragging rights of saying they were the first ones to have 5G.

The final announcement I saw on that same day was one by T-Mobile saying they would begin deploying early 5G in cell sites in 2020. But the real news is that they aren’t planning on charging any more for any extra 5G speeds or features.

I come back to my original question about why I write about 5G so often. A lot of my clients ask me if they should be worried about 5G and I don’t have an answer for them. I can see that actual 5G technology is going to take a lot longer to come to market than the big carriers would have you believe. But I look at T-Mobile’s announcement on price and I also have to wonder what the cellular companies will really do once 5G works. Will AT&T and Verizon both spend billions to put 5G small cells in residential neighborhoods if it doesn’t drive any new cellular revenues? I have to admit that I’m skeptical – we’re going to have to wait to see what the carriers do rather than listen to what they say.

5G For Rural America?

FCC Chairman Ajit Pai recently addressed the NTCA-The Rural Broadband Association membership and said that he saw a bright future for 5G in rural America. He sees 5G as a fixed-wireless deployment that fits in well with the fiber deployment already made by NTCA members.

The members of NTCA are rural telcos and many of these companies have upgraded their networks to fiber-to-the-home. Some of these telcos tackled building fiber a decade or more ago and many more are building fiber today using money from the ACAM program – part of the Universal Service Fund.

Chairman Pai was talking to companies that largely have been able to deploy fiber, and since Pai is basically the national spokesman for 5G it makes sense that he would try to make a connection between 5G and rural fiber. However, I’ve thought through every business model for marrying 5G and rural fiber and none of them make sense to me.

Consider the use of millimeter wave spectrum in rural America. I can’t picture a viable business case for deploying millimeter wave spectrum where a telco has already deployed fiber drops to every home. No telco would spend money to create wireless drops where they have already paid for fiber drops. One of the biggest benefits from building fiber is that it simplifies operations for a telco – mixing two technologies across the same geographic footprint would add unneeded operational complications that nobody would tackle on purpose.

The other business plan I’ve heard suggested is to sell wholesale 5G connections to other carriers as a new source of income. I also can’t imagine that happening. Rural telcos are going to fight hard to keep out any competitor that wants to use 5G to compete with their existing broadband customers. I can’t imagine a rural telco agreeing to provide fiber connections to 5G transmitters that would sit outside homes and compete with their existing broadband customers, and a telco that lets in a 5G competitor would be committing economic suicide. Rural business plans are precarious, by definition, and most rural markets don’t generate enough profits to justify two competitors.

What about using 5G in a competitive venture where a rural telco is building fiber outside of their territory? There may come a day when wireless loops have a lower lifecycle cost than fiber loops. But for now, it’s hard to think that a wireless 5G connection with electronics that need to be replaced at least once a decade can really compete over the long-haul with a fiber drop that might last 50 or 75 years. If that math flips we’ll all be building wireless drops – but that’s not going to happen soon. It’s probably going to take tens of millions of installations of millimeter wave drops until telcos trust 5G as a substitute for fiber.

Chairman Pai also mentioned mid-range spectrum in his speech, specifically the upcoming auction for 3.5 GHz spectrum. How might mid-range spectrum create a rural 5G play that works with existing fiber? It might be a moot question since few rural telcos are going to have access to licensed spectrum.

But assuming that telcos could find mid-range licensed spectrum, how would that benefit from their fiber? As with millimeter wave spectrum, a telco is not going to deploy this technology to cover the same areas where they already have fiber connections to homes. The future use of mid-range spectrum will be the same as it is today – to provide wireless broadband to customers that don’t live close to fiber. The radios will be placed on towers, the taller the better. These towers will then make connections to homes using dishes that can communicate with the tower.

Many of the telcos in the NTCA are already deploying this fixed wireless technology today outside of their fiber footprint. This technology benefits from having towers fed by fiber, but this rarely the same fiber that a telco is using to serve customers. In most cases this business plan requires extending fiber outside of the existing service footprint – and Chairman Pai said specifically that he saw advantage for 5G from existing fiber.

Further, it’s a stretch to label mid-range spectrum point-to-multipoint radio systems as 5G. From what numerous engineers have told me, 5G is not going to make big improvements over the way that fixed wireless operates today. 5G will add flexibility for the operator to fine-tune the wireless connection to any given customer, but the 5G technology won’t inherently increase the speed of the wireless broadband connection.

I just can’t find any business plan that is going to deliver 5G in rural America that takes advantage of the fiber that the small telcos have already built. I would love to hear from readers who might see a possibility that I have missed. I’ve thought about this a lot and I struggle to find the benefits for 5G in rural markets that Chairman Pai has in mind. 5G clearly needs a fiber-rich environment – but companies who have already built rural fiber-to-the-home are not going to embrace a second overlay technology or openly allow competitors onto their networks.

AT&T’s 5G Strategy

AT&T recently described their long-term 5G strategy using what they call the 3 pillars of 5G – the three areas where the company is putting their 5G focus. The first pillar is a concentration on 5G cellular, and the company’s goal is to launch a 5G-based cellular service, with some cities coming on board in the second half of 2020. This launch will use frequencies in the sub-6 GHz range. This admission that there won’t be any AT&T 5G until at least 2020 contradicts the AT&T marketing folks who are currently trying to paint the company’s 4G LTE as pre-5G.

The biggest problem for the public will be getting a 5G cellphone. AT&T is working with Samsung to hopefully launch two phones later this year that have some 5G capability. As always with a new generation of wireless technology, the bottleneck will be in handsets. The cell phone makers can’t just make generic 5G phones – they have to work with the carriers to be ready to support the spectific subset of 5G features that are released. You might recall that the 5G cellular specification contains 13 improvements, and only the first generation of a few of those will be included in the first generation 5G cell sites. Cellphone manufacturers will also have to wrestle with the fact that each big cellular carrier will introduce a different set of 5G features.

This is a real gamble for cellphone makers because a 5G phone will become quickly obsolete. A 5G phone sold in late 2019 probably won’t include all of the 5G features that will be on the market by late 2020 – and this is likely to be true for the next 3 or 4 years as the carriers roll out incremental 5G improvements. It’s also a gamble for customers because anybody that buys an early 5G cellphone will have early bragging rights, but those cool benefits can be out of date in six months. I think most people will be like me and will wait a few years until the 5G dust settles.

AT&T’s second pillar is fixed wireless. This one is a head-scratcher because they are talking about the fixed cellular product they’ve already been using for several years – and that product is not 5G. This is the product that delivers broadband to homes using existing low-band cellular frequencies. This is not the same as Verizon’s product that delivers hundreds of megabits per second but is instead a product that delivers speeds up to 50 Mbps depending upon how far a customer lives from a cell tower – with reports that most households are getting 15 Mbps at best. This is the product that AT&T is mostly using to satisfy its CAF II requirements in rural America. All of the engineers I’ve talked to don’t think that 5G is going to materially improve this product.

The final pillar of AT&T’s strategy is edge computing. What AT&T means by this is to put fast processors at customer sites when there is the need to process low-latency, high-bandwidth data. Like other carriers, AT&T has found that not everything is suited for the cloud and that trying to send big data to and from the cloud can create a bandwidth bottleneck and add latency. This strategy doesn’t require 5G and AT&T has already been deploying edge routers. However, 5G will enhance this ability at customer sites that need to connect a huge number of devices simultaneously. 5G can make it easier to connect to a huge number of IoT devices in a hospital or to 50,000 cell phones in a stadium. The bottom line is that the migration to more edge computing is not a 5G issue and applies equally to AT&T’s fiber customers.

There is really nothing new in the three-pillar announcement and AT&T has been talking about all three applications from some time – but the announcement does highlight the company’s focus for stockholders.

In what was mostly a dig at Verizon, AT&T’s CEO Randall Stephenson did hold out the possibility of AT&T following Verizon into the 5G fixed wireless local loop using millimeter wave spectrum – however, he said such a product offering is probably three to five years into the future. He envisions the product as an enhancement to AT&T’s fiber products, not necessarily a replacement. He emphasized that AT&T is happy with the current fiber deployments. He provided some new statistics on a recent earnings call and said the company is seeing customer penetration rates between 33% and 40% within 18 months of new fiber deployment and penetration around 50% after three years. Those are impressive statistics because AT&T’s fiber deployments have been largely in urban areas competing with the big cable companies.

A year ago, Stephenson said that getting sufficient backhaul was his number one concern with deploying high-bandwidth wireless. While he hasn’t repeated that recently, it fits in with his narrative of seeing millimeter wave radio deployments in the 3-5 year time frame. The company recently released a new policy paper on its AirGig product that says that the product is still under development and might play well with 5G. AirGig is the mysterious wireless product that shoots wireless signals along power lines and somehow uses the power lines to maintain focus of the signal. Perhaps the company is seeing a future path for using AirGig as the backhaul to 5G fixed wireless deployments.

Windstream Turns Focus to Wireless

Windstream CEO Tony Thomas recently told investors that the company plans to stress wireless technology over copper going into the future. The company has been using point-to-point wireless to serve large businesses for several years. The company has more recently been using fixed point-to-multipoint wireless technology to satisfy some of it’s CAF II build-out requirements.

Thomas says that the fixed wireless technology blows away what could be provided over the old copper plant with DSL. In places with flat and open terrain like Iowa and Nebraska the company is seeing rural residential broadband speeds as fast as 100 Mbps with wireless – far faster than can be obtained with DSL.

Thomas also said that the company is also interested in fixed 5G deployments, similar to what Verizon is now starting to deploy – putting 5G transmitters on poles to serve nearby homes. He says the company is interested in the technology in places where they are ‘fiber rich’. While Windstream serves a lot of extremely rural locations, there also serve a significant number of towns and small cities in their incumbent service areas that might be good candidates for 5G.

The emphasis on wireless deployments puts Windstream on the same trajectory as AT&T. AT&T has made it clear numerous times to the FCC that they company would like to tear down rural copper wherever it can to serve customers with wireless. AT&T’s approach differs in that AT&T will be using its licensed cellular spectrum and 4G LTE in rural markets while Windstream would use unlicensed spectrum like various WISPs.

This leads me to wonder if Windstream will join the list of big telcos that will largely ignore its existing copper plant moving into the future. Verizon has done it’s best to sell rural copper to Frontier and seems to be largely ignoring its remaining copper plant – it’s the only big telcos that didn’t even bother to chase the CAF II money that could have been used to upgrade rural copper.

The new CenturyLink CEO made it clear that the company has no desire to make any additional investments that will earn ‘infrastructure returns’, meaning investing in last mile networks, both copper and fiber. You can’t say that Frontier doesn’t want to continue to support copper, but the company is clearly cash-stressed and is widely reported to be ignoring needed upgrades and repairs to rural copper networks.

The transition from copper to wireless is always scary for a rural area. It’s great that Windstream can now deliver speeds up to 100 Mbps to some customers. However, the reality of wireless networks are that there are always some customers who are out of reach of the transmitters. These customers may have physical impediments such as being in a valley or behind a hill and out of line-of-sight from towers. Or customers might just live to far away from a tower since all of the wireless technologies only work for some fixed distance from a tower, depending upon the specific spectrum being used.

It makes no sense for a rural telco to operate two networks, and one has to wonder what happens to the customers that can’t get the wireless service when the day comes when the copper network gets torn down. This has certainly been one of the concerns at the FCC when considering AT&T’s requests to tear down copper. The current FCC has relaxed the hurdles needed to tear down copper and so this situation is bound to arise. In the past the telcos had carrier of last-resort obligations for anybody living in the service area. Will they be required to somehow get wireless signal to those customers that fall between the cracks? I doubt that anybody will force them to do so. It’s not far-fetched to imagine customers living within a regulated telcos service area who can’t get telephone or broadband service from the telco.

Customers in these areas also have to be concerned with the future. We have wide experience that the current wireless technologies don’t last very long. We’ve seen electronics wear out and become functionally obsolete within seven years. Will Windstream and the other telcos chasing the wireless technology path dedicate enough capital to constantly replace electronics? We’ll have to wait for that answer – but experience says that they will cut corners to save money.

I also have to wonder what happens to the many parts of the Windstream service areas that are too hilly or too wooded for the wireless technology. As the company becomes wireless-oriented will they ignore the parts of the company stuck with copper? I just recently visited some rural counties that are heavily wooded, and which were told by local Windstream staff that the upgrades they’ve already seen on copper (which did not seem to make much difference) were the last upgrades they might ever see. If Windstream joins the other list of big telcos that will ignore rural copper, then these networks will die a natural death from neglect. The copper networks of all of the big telcos are already old and it won’t take much neglect to push these networks into the final death spiral.

Can Cable Fight 5G?

The big cable companies are clearly worried about 5G. They look at the recently introduced Verizon 5G product and they understand that they are going to see something similar over time in all of their metropolitan markets. Verizon is selling 5G broadband – currently at 300 Mbps second, but promised to get faster in the future – for $70 standalone or for $50 for those with Verizon cellular.

This is the nightmare scenario for them because they have finally grown to the point where they are approaching a near monopoly in most markets. They have successfully competed with DSL and quarter after quarter have been taking DSL customers from the telcos. In possibly the last death knell for DSL, both Comcast and Charter recently increased speeds of their base products to at least 200 Mbps. Those speeds makes it hard for anybody to justify buying DSL at 50 Mbps or slower.

The big cable companies have started to raise broadband rates to take advantage of their near-monopoly situation. Charter just recently raised bundled broadband prices by $5 per month – the biggest broadband price increase I can remember in a decade or more. Last year a major Wall Street analyst advised Comcast that their basic broadband price ought to be $90.

But now comes fixed 5G. It’s possible that Verizon has found a better bundle than the cable companies because of the number of households that already have cellphones. It’s got to be tempting to homes to buy fast broadband for only $50 per month in a bundle.

This fixed 5G competition won’t come over night. Verizon is launching 5G in urban markets where they already have fiber. Nobody knows how fast they will really implement the product, due mostly to distrust of a string of other Verizon hype about 5G. But over time the fixed 5G will hit markets. Assuming Verizon is successful, then others will follow them into the market. I’m already seeing some places where companies American Tower are building 5G ‘hotels’ at poles, which are vaults large enough to accommodate several 5G providers at the same location.

We got a clue recently about how the cable companies might fight back against 5G. A number of big cable companies like Comcast, Charter, Cox and Midco announced that they will be implementing the new 10 Gbps technology upgrade from CableLabs. These cable companies just recently introduced gigabit service using DOCSIS 3.1. It looks like the cable companies will fight against 5G with speed. It sounds like they will advertise speeds far faster than the 5G speeds and try to win the speed war.

But there is a problem with that strategy. Cable systems with the DOCSIS 3.1 upgrade can clearly offer gigabit speeds, but in reality cable company networks aren’t ready or able to deliver that much speed to everybody. Fiber networks can easily deliver a gigabit to every customer, and with an electronics upgrade can offer 10 Gbps to everybody, as is happening in parts of South Korea. But cable networks have an inherent weakness that makes gigabit speed problematical.

Cable networks are still shared networks and all of the customers in a node share the bandwidth. Most cable nodes are still large with 150 – 300 customers in each neighborhood node, and some with many more. If even a few customers start really use gigabit speeds then the speed for everybody else in the node will deteriorate. That’s the issue that caused cable networks to bog done in the evenings a decade ago. Cable companies fixed the problem then by ‘splitting’ the nodes, meaning that they build more fiber to reduce the number of homes in each node. If the cable companies want to really start pushing gigabit broadband, and even faster speeds, then they are faced with that same dilemma again and they will need another round, or even two rounds of node splits.

For now I have serious doubts about whether Comcast and Charter are even serious about their gigabit products. Comcast gigabit today costs $140 plus $10 for the modem. The prices are lower in markets where the company is competing against fiber, and customers can also negotiate contract deals to get the gigabit price closer to $100. Charter has similar pricing – in Oahu where there is competition they offer a gigabit for $105, and their price elsewhere seem to be around $125.

Both of these companies are setting gigabit prices far above Google’s Fiber’s $70 gigabit. The current cable company gigabit is not a serious competitor to Verizon’s $50 – $70 price for 300 Mbps. I have a hard time thinking the cable companies can compete on speed alone – it’s got to be a combination of speed and price. The cable companies can compete well against 5G if they are willing to price a gigabit at the $70 Verizon 5G price and then use their current $100+ price for 10 Gbps. That pricing strategy will cost them a lot of money in node upgrades, but they would be smart to consider it. The biggest cable companies have already admitted that their ultimate network needs to be fiber – but they’ve been hoping to milk the existing coaxial networks for another decade or two. Any work they do today to reduce node size would be one more step towards an eventual all-fiber network – and could help to stave off 5G.

It’s going to be an interesting battle to watch, because if we’ve learned anything in this industry it’s that it’s hard to win customers back after you lose them. The cable companies currently have most of the urban broadband customers and they need to act now to fight 5G – not wait until they have lost 30% of the market.

The Physics of Millimeter Wave Spectrum

Many of the planned used for 5G rely upon the use of millimeter wave spectrum, and like every wireless technology the characteristics of the spectrum defines both the benefits and limitations of the technology. Today I’m going to take a shot at explaining the physical characteristics of millimeter wave spectrum without using engineering jargon.

Millimeter wave spectrum falls in the range of 30 GHz to 300 GHz, although currently there has been no discussion yet in the industry of using anything higher than 100 GHz. The term millimeter wave describes the shortness of the radio waves which are only a few millimeters or less in length. The 5G industry is also using spectrum that is a little longer than millimeter waves size such as 24 GHz and 28 GHz – but these frequencies share a lot of the same operating characteristics.

There are a few reasons why millimeter wave spectrum is attractive for transmitting data. The millimeter spectrum has the capability of carrying a lot of data, which is what prompts discussion of using millimeter wave spectrum to deliver gigabit wireless service. If you think of radio in terms of waves, then the higher the frequency the greater the number of waves that are being emitted in a given period of time. For example, if each wave carries one bit of data, then a 30 GHz transmission can carry more bits in one second than a 10 GHz transmission and a lot more bits than a 30 MHz transmission. It doesn’t work exactly like that, but it’s a decent analogy.

This wave analogy also defines the biggest limitation of millimeter wave spectrum – the much shorter effective distances for using this spectrum. All radio waves naturally spread from a transmitter, and in this case thinking of waves in a swimming pool is also a good analogy. The further across the pool a wave travels, the more dispersed the strength of the wave. When you send a big wave across a swimming pool it’s still pretty big at the other end, but when you send a small wave it’s often impossible to even notice it at the other side of the pool. The small waves at millimeter length die off faster. With a higher frequency the waves are also closer together. Using the pool analogy, that means that the when waves are packed tightly together then can more easily bump into each other and become hard to distinguish as individual waves by the time they get to the other side of the pool. This is part of the reason why shorter millimeter waves don’t carry as far as other spectrum.

It would be possible to send millimeter waves further by using more power – but the FCC limits the allowed power for all radio frequencies to reduce interference and for safety reasons. High-power radio waves can be dangerous (think of the radio waves in your microwave oven). The FCC low power limitation greatly reduces the carrying distance of this short spectrum.

The delivery distance for millimeter waves can also be impacted by a number of local environmental conditions. In general, shorter radio waves are more susceptible to disruption than longer spectrum waves. All of the following can affect the strength of a millimeter wave signal:

  • Mechanical resonance. Molecules of air in the atmosphere naturally resonate (think of this as vibrating molecules) at millimeter wave frequencies, with the biggest natural interference coming at 24 GHz and 60 GHz.
  • Atmospheric absorption. The atmosphere naturally absorbs (or cancels out) millimeter waves. For example, oxygen absorption is highest at 60 GHz.
  • Millimeter waves are easily scattered. For example, the millimeter wave signal is roughly the same size as a raindrop, so rain will scatter the signal.
  • Brightness temperature. This refers to the phenomenon where millimeter waves absorb high frequency electromagnetic radiation whenever they interact with air or water molecules, and this degrades the signal.
  • Line-of-sight. Millimeter wave spectrum doesn’t pass through obstacles and will be stopped by leaves and almost everything else in the environment. This happens to some degree with all radio wavs, but at lower frequencies (with longer wavelengths) the signal can still get delivered by passing through or bouncing off objects in the environment (such as a neighboring house and still reach the receiver. However, millimeter waves are so short that they are unable to recover from collision with an object between the transmitter and receiver and thus the signal is lost upon collision with almost anything.

One interesting aspect of these spectrum is that the antennas used to transmit and receive millimeter wave spectrum are tiny and you can squeeze a dozen or more antenna into a square inch. One drawback of using millimeter wave spectrum for cellphones is that it takes a lot of power to operate multiple antennas, so this spectrum won’t be practical for cellphones until we get better batteries.

However, the primary drawback of small antennas is the small target area used to receive a signal. It doesn’t take a lot of spreading and dispersion of the signal to miss the receiver. For spectrum in the 30 GHz range the full signal strength (and maximum bandwidth achievable) to a receiver can only carry for about 300 feet. With greater distances the signal continues to spread and weaken, and the physics show that the maximum distance to get any decent bandwidth at 30 GHz is about 1,200 feet. It’s worth noting that a receiver at 1,200 feet is receiving significantly less data than one at a few hundred feet. With higher frequencies the distances are even less. For example, at 60 GHz the signal dies off after only 150 feet. At 100 GHz the signal dies off in 4 – 6 feet.

To sum all of this up, millimeter wave transmission requires a relatively open path without obstacles. Even in ideal conditions a pole-mounted 5G transmitter isn’t going to deliver decent bandwidth past about 1,200 feet, with the effective amount of bandwidth decreasing as the signal travels more than 300 feet. Higher frequencies mean even less distance. Millimeter waves will perform better in places with few obstacles (like trees) or where there is low humidity. Using millimeter wave spectrum presents a ton of challenges for cell phones – the short distances are a big limitation as well as the extra battery life needed to support extra antennas. Any carrier that talks about deploying millimeter wave in a way that doesn’t fit the basic physics is exaggerating their plans.

Is the Public Buying the 5G Hype?

T-Mobile recently conducted a survey, conducted by HarrisT, that looks in detail about how the public feels about the role of pending new technologies. They expect to repeat this survey quarterly to track how public perceptions of technology changes over time.

As you would expect, a significant number of the questions in the poll were about 5G. I’m sure that T-Mobile’s motivation for conducting the survey is due to the fact that they are one of the few companies in the industry that are not hyping 5G. They expect 5G to start creeping into the industry in 2020 and then taking as much as a decade to become a widespread reality.

The survey started by asking if respondents had heard of various new technologies. The 5G hype isn’t fully pervasive yet with 57% having heard of the technology. For other technologies: Internet of Things – 29%; machine learning – 26%; virtual reality – 83%; artificial intelligence – 78%; cloud computing – 52% and blockchain – 19%.

One of the most interesting responses in the survey is the public expectation of when they expect to see 5G in the market place. Of those that have heard of 5G, 29% thought it was already here in late 2018. 35% more think they’ll see 5G in 2019 and another 25% expect 5G in 2020. This response has to reflect the flood of marketing hype and press releases extolling 5G. The public has been inundated for several years by articles and press releases that declare that 5G is going to solve our broadband problems by delivering huge data speeds wirelessly everywhere.

When asked more specifics about 5G, 64% were somewhat excited or very excited about 5G in general. They were also somewhat or very excited about the following attributes of 5G: faster upload and download speeds – 92%; wider network coverage – 91%; higher quality streaming video – 85%; higher quality voice calls – 89%; less lag time on mobile devices – 90%; more reliable mobile connections – 93%; greater number of connected devices – 80%; smart city data sensors – 68%; driverless vehicles – 50%; virtual reality in the work environment – 59%; smart energy grids – 75%; supercharged IoT – 64%; expanded use of drones – 47%; next generation artificial intelligence – 59%; telehealth – 68%; remote surgery – 59%; real time language translation – 72%; replacement of landline broadband connections – 75%; replacement of traditional cable TV – 75%.

Interestingly, only 27% of total respondents thought that 5G would have a big influence on their daily life.

In a finding that I find disturbing, 65% of respondents think 5G will have a positive impact on rural America. Even the biggest 5G proponents admit that 5G is going to be hard to justify in low-density areas. It’s not hard to understand this belief because I’ve seen numerous articles that make this claim. 79% think 5G will have a positive impact in cities.

When asked which companies would be leaders in 5G, the unsurprising responses include Verizon (43%), AT&T (36%), Apple (43%), Samsung (35%) and T-Mobile (20%). However, there were surprises on this list including Amazon (24%), Comcast (12%), Google (36%), Facebook (12%), Microsoft (34%) and Dish Networks (5%).

The public believes that 5G is going to bring price increases. 84% said they thought that 5G would result in higher cellular service prices. 77% said they thought 5G would lead to higher cable TV prices (this has me scratching my head). 81% said they thought 5G would lead to higher process for home broadband – but wouldn’t increased competition for home broadband bring lower prices? 86% expect the prices for smart phones to be higher.

Overall, the survey shows an unrealistic public perception about when we’ll see the benefits of 5G. It’s not hard to understand this misperception since there are untold articles making it sound like we’re on the verge of a 5G revolution. I’m guessing this might have been one of the motivations for T-Mobile to sponsor this survey since they are one of the most realistic voices in the industry talking about the 5G time line. It will be interesting to see what the public thinks in a few years after very little 5G has actually been implemented. But perhaps I’m just being overly skeptical since the big carriers like AT&T are now extolling their 4G LTE product as 5G – maybe the public will but it.

AT&T is Not Launching Mobile 5G

AT&T recently took the next step in the 5G hype race by announcing that it is releasing the first mobile 5G device. The announcement was made at end of the year to cover past AT&T announcements that the company would launch mobile 5G in 2018. The company can now say that they beat Verizon and Sprint to the market.

The AT&T announcement is referring to the device they are calling a puck. It’s a small Netgear modem that is being touted as a 5G mobile hotspot. The puck is based upon at least a few aspects of the 3GPP NR standard, allowing AT&T to claim it’s 5G. AT&T has not been fully forthcoming about how the device works. Where available the device will supposedly grab bandwidth from AT&T’s 5G cellular network – but since the 5G network is mostly still imaginary, in most places it will grab signal from the existing 4G LTE network. Within a home the puck will transmit WiFi, just like any other WiFi router.

There is no real product here. For at least three months AT&T will be giving away the puck and service for free to selected users. After that they’ve said the pricing will be $499 for the puck plus $70 monthly for bandwidth with an incredibly stingy 15 GB data cap. My prediction is that this product never makes it to market because it’s hard to envision anybody in an urban area willing to pay $70 a month such a small amount of WiFi bandwidth. The only market for the puck is possibly a few early adapters with money to burn who want to be able to say they owned the first 5G devices.

This announcement sets a new low for 5G hype. What I found most disturbing is that dozens of news sites picked up the story and basically spit back the AT&T press release and called it news. Those dozens of articles give the public the impression that 5G mobile is right around the corner, which is exactly what AT&T intended – they want the public to equate 5G and the AT&T brand name together. To be fair, there are several industry articles that didn’t buy into the AT&T hype.

The AT&T announcement also made this sound like a breakthrough technology by implying that this will deliver faster cellular speeds. There is a lot needed before there is a faster 5G cellular network. First, AT&T would need to install 5G transmitters on residential streets, requiring them to build neighborhood fiber networks. For the puck to work with millimeter wave spectrum AT&T would need to put a small antenna on the outside of a home to receive the signal since millimeter wave bandwidth won’t pass through the walls of a home. A network that will deliver residential millimeter wave cellular bandwidth is nearly identical to a network that would deliver 5G fixed broadband.

AT&T is not taking any of those needed steps. In fact, AT&T’s CTO Andre Fuetsch spent the fall repeatedly taking potshots at Verizon’s 5G deployment, saying that Verizon is making a mistake chasing the ‘fixed’ 5G market.

To further deflate this announcement, AT&T’s CFO John Stephens recently told AT&T investors to not expect any 5G revenues in 2019. He admitted it will take many years until there are enough 5G phones in the market to make a noticeable difference in revenues. It seems the only cellular carrier being truthful about 5G is T-Mobile which says it will begin introducing some 5G characteristics into their cell sites starting in 2020.

The bottom line is that AT&T just announced the release of a WiFi router that works off their 4G LTE network, but which supposedly will incorporate at least some aspects of the 3GPP NR standard. The company isn’t planning to charge for the product and it’s hard to envision anybody buying hotspot bandwidth at the prices they announced. But AT&T got what they wanted, which was dozens of news articles declaring that AT&T was the first to market with mobile 5G. I bet a decade from now that’s exactly what the Wikipedia article on 5G will say – and that’s all AT&T was really shooting for.

Telecom Predictions for 2019

It’s that time of year when I look forward at what the next year might bring to the industry. I see the following as the biggest telecom trends for 2019:

5G Will Not Save the World (or the Industry). This will be the year when we will finally stop seeing headlines about how 5G will transform society. There will be almost no actual introduction of 5G in networks, but we’ll still see numerous press releases by the big ISPs crowing about fictional 5G achievements.

CAF II Buildout Nearly Complete, but Few Notice. The CAF II upgrades will not have the impact hoped for by the FCC. Many areas that should have gotten speed increases to at least 10/1 Mbps will get something less, but nobody will officially monitor or note it. Households that buy the upgrades to 10/1 will still feel massively underserved since those speeds are already seriously obsolete.

People Will Wonder Why They Bought 5G Cellphones and 802.11ax Routers. The wireless carriers will begin charging premium prices for 5G-capable cellular phone yet there will be no 5G cell sites deployed. Households will upgrade to 802.11ax WiFi routers without realizing that there are no compatible devices in the home. Both sets of customers will feel cheated since there will be zero improvement in performance. Yet we’ll still see a few articles raving about the performance of each technology.

FCC Will Continue to Work Themselves out of the Regulatory Business. The current FCC will continue on the path to deregulate the large carriers to the fullest extent possible. They will continue to slant every decision in the direction of the big ISPs while claiming that every decision helps rural broadband.

Rural America Will Realize that Nobody is Coming to Help. I predict that hundreds of rural communities will finally realize that nobody is bringing them broadband. I expect many more communities to begin offering money for public/private partnerships as they try desperately to not fall on the wrong side of the broadband divide.

Broadband Prices Start to Climb. 2019 will be the first year that the world will notice the big ISP strategy to significantly increase broadband prices. We saw the first indication in November when Charter increased bundled broadband prices by $5 per month – the biggest broadband price increase in my memory. All the big ISPs are hoping to have broadband prices to $90 within 5 – 7 years.

Corporate Lobbyists Will Drive Policy. In 2018 there were numerous FCC decisions that came straight from the pens of telecom lobbyists. In 2019 those lobbyists will drive state and federal telecom legislation and FCC decisions.

Comcast and Charter Continue to Eat into Cellular Market. These two cable companies will quietly, yet significantly begin eating into the cellular markets in urban areas. I still don’t expect a major reaction by the cellar companies, but by 2020 we should start seeing cellular prices take another tumble.

Household Bandwidth Usage Will Continue to Grow. There will be no slowdown in the growth of household broadband as homes add many more bandwidth-capable devices to their homes. Another few million customers will cut the cable TV cord and ratchet up bandwidth usage. Online programming will routinely first offer 4K video and we’ll see the first commercial 8K video online.

We’ll See First Significant Launches of LEO Satellites. There will be little public notice since the early market entries will not be selling rural broadband but will be supporting corporate WANs, cellular transport and the development of outer space networks between satellites.

25 New Online Programmers Emerge. There will be a flood of new online programming options as numerous companies jump into the market. We won’t see many, and possibly no failures this year, but within a few years the market reality will drive out companies that can’t gain enough market share.

Transport Price Pressure Tightens. Anybody selling transport to cellular companies will see big pressure to lower prices. Those who ignore the pressure will find out that the carriers are willing to build fiber to bypass high costs.

Big Companies Will Get Most New Spectrum. The biggest ISPs and cellular carriers will still gobble up the majority of new spectrum, meaning improved spectrum utilization for urban markets while rural America will see nearly zero benefits.
