What is the Killer App for 5G?

Early on in the 3G era, video calling was a hoped-for new “killer app.” That did not happen. But it has become commonplace on 4G networks. In a similar way, content services were expected to flourish in the 3G era. That did not happen until 4G.

Augmented reality apps were supposed to develop on 3G networks. That still has not happened.

In fact, many would find it hard to point to a killer app  for 3G. Eventually, new apps do emerge. And some might say the early value of 4G was just speed.  

You might argue text messaging was the new killer use case for 2G. You might suggest mobile email and Internet access was the legacy of 3G. Video entertainment is developing as the singular new app that defines 4G.

Internet of things is expected to drive the futuristic new use cases for 5G. Many believe 5G fixed wireless, though, will represent the early new use cases, beyond bolstering consumer internet access speeds and augmenting 4G capacity in geographic areas where congestion is an issue on busy cell sites.  

Still, it is fair to say we are likely to be surprised by what 5G brings, or fails to bring, as has been the case for the other next G mobile networks.

Among the possible surprises could well be that hoped-for new use cases do not flourish in the 5G era, but take longer to reach near-ubiquity. That is why some believe 5G will wind up being more like 3G--a platform whose innovation lagged expectations--than 4G, a network platform that some would argue largely developed on the promise of new apps enabled by greater capacity.

As was the case for 4G, which provided significantly faster speeds, making video consumption feasible, 5G will boost access speeds, by an even greater margin. But the bigger long-term change is the shift to ultra-low latency.

It would be a reasonable supposition that use cases for higher speed will develop sooner, with greater scale, than use cases for ultra-low latency. And that is why some believe 5G might be more like 3G than 4G.

The wild card is the role of enterprise apps and use cases. Some of us argue that what makes 5G clearly different from all prior mobile generations is that brand-new use cases are more likely to emerge in the enterprise segment of the market.

In the case of prior generations, growth and use cases were lead by consumer applications. That is unlikely to be the case for 5G, if internet of things actually emerges as the killer set of apps.

Will 5G New Use Cases Flourish Only in 6G Era?

If past patterns hold, 5G will reach its peak of adoption in a bit more than a decade, while having a useful life as long as 20 years. So we will know, within a decade, how well 5G lives up to its promise as a platform for new use cases related to internet of things, and how well new ultra-low-latency applications have developed.

There is precedent for something else as well. Many innovations hoped for in the 3G era arguably flourished only in the 4G era. So it is conceivable that although 5G will see the early years for many new use cases, those applications will thrive only in the 6G era.

Despite clear evidence that mobile operators in the United States, Japan, South Korea and China are charging fast into 5G, with firms in each of those countries believing 5G leadership will lead to broader benefits, many operators in other nations are less optimistic about the near term business case.

In some cases, that skepticism or agnosticism also has other roots: recent and major investments in 4G, uncertain spectrum allocations or the general state of the mobile business (very low growth) in general, which raises the risk of big new investments in 5G.

Add to that divergence the sense in early-adopter countries that 5G is about industrial policy, while perhaps not a plausible possibility in most countries, and the split of opinion is easy to explain.

Optimists might point out that business model fuzziness also was a characteristic of both 3G and 4G, so some amount of uncertainty is perhaps typical of next-generation mobile platforms in recent eras that have seen revenue growth drivers migrate from voice to messaging to internet access for revenue growth, and which now will have to depend on additional new growth drivers in the 5G era beyond internet access for people on smartphones.

It also is fair to say that early adopters in 5G vary by continent, with mobile operators in the United States, Japan, China, South Korea moving early and aggressively into 5G, while European, African, South American and broader Asian operators are more circumspect.

In some instances, the hesitation is related to the recency of 4G investments. In other cases the difficulty of the mobile business model in general makes a major upgrade cycle unpalatable.

There are divides, by continent, on the matter of internet of things upside as well, possibly because many observers see the biggest early revenue cases developing in North America and parts of Asia.

So it might not be surprising that mobile operators in the United States and East Asia are more optimistic about the near term 5G and IoT business cases (as IoT upside will be dependent on 5G, in important cases).

In Europe, the IoT opportunity often is included in discussions of the “fourth industrial revolution.”

One hears the term of art used less in the North American markets, perhaps suggesting different perceptions of where opportunity lies. In a broad sense, users of the term fourth industrial revolution seem to use it in a sense similar to “digitalization” and a bit more reliant on applying artificial intelligence to business processes.

Other touted revenue platforms such as edge computing are simply early in development, as edge computing requires new lead apps such as autonomous vehicles to drive such requirements.

Some observers also note the nebulous discussions and status of artificial intelligence within the service provider community at the moment, though, perhaps surprisingly, AI is seen by some as having more relevance for mobile operators than 5G, IoT or edge computing.

The point is that near-term optimism about 5G, internet of things and edge computing--if not complete conviction at the same level--is higher in a few markets than across most of the globe.

In part, that is because 5G business cases are part of the broader IoT and edge computing trends. Without significant IoT growth, it is hard to make the case either for 5G or edge computing.

At the moment, 5G and IoT are a Rorschach test. Different people see different things.

Amazon, Content Suppliers Wrangle Over Prices

Amazon is looking to increase its cut of revenue from some subscription services available through Prime Video by 10 to 20 percentage points to as high as 50 percent, The Information reports.  

Amazon’s share from services such as HBO almost certainly parts with less of the gross amount of subscriber fees. Smaller and niche services might pay half of their sales to Amazon.

Amazon’s attention likely is focused on its share of revenues from channels that currently pay less than 50 percent to Amazon when a sale is made.

Disagreements about revenue splits are commonplace in the entertainment video business. That is especially true for streaming video services, which have difficult business model unless scale is obtained.

To be sure, garnering greater share of subscription revenue makes business sense for ecosystem partners when revenues are growing or shrinking. It matters not which way the trend is pointing.

And though the economics of linear and over-the-top subscriptions are quite different, the OTT model can make sense even for internet service providers who sell linear and OTT products. At a retail level, zero rating of video consumption, or big usage buckets, are necessary.

5G Can Improve Rural Connectivity if Spectrum is Free

It is far from clear how well 5G networks might help improve or supply quality internet access in rural, mountainous and thinly-populated parts of the United States. Almost by definition, such areas do not support sustained business models for fixed networks, and require subsidies.

That is why hundreds of independent wireless internet service providers now are the way many people in rural areas get internet access services. Those firms also tend to rely on use of unlicensed spectrum to make the business model work.

The same sort of economics work for Wi-Fi. Low entry cost, as spectrum is available at no cost, is key.

One might argue that should continue to be the case in the 5G era: networks will have to be wireless, and will require unlicensed spectrum access.

It probably matters less whether the unlicensed spectrum is gotten using shared or dedicated mechanisms (Citizens Broadband Radio Service, which is shared; or new unlicensed spectrum in the millimeter wave bands). The point is that tough business models require no-cost access to spectrum.

Whether 5G networks can make a big difference in providing good rural coverage hinges on access to no-cost and low-cost spectrum.

Over the past few years, some have worried about the cost of 5G spectrum, although spectrum prices are dropping, generally speaking, in part because there is a huge increase in supply, and because mobile operators must now more carefully weigh the cost of new spectrum against expected financial return.  

Also, firm strategies now vary. Some firms believe use of unlicensed spectrum will be more important. Others substitute small cells for additional spectrum. Some need additional spectrum more urgently than others, based on present holdings.

Recent auctions of 3.5-GHz spectrum have no clear pattern, especially since the various auctions featured different amounts of total spectrum and different license allotments (bigger or smaller amounts of spectrum per license), and there always are local market drivers (some contestants have greater needs for spectrum).

The point is that supply and demand issues affect price, as always. Finland offered the most 3.5-GHz spectrum, at 390 MHz. Spain and Italy each sold 200 MHz. U.K. regulators auctioned 150 MHz.

Finland’s prices wound up at 0.04 euros per megaHertz pop (a MHz POP represents one megahertz of bandwidth passing one person in the coverage area).  Spectrum sold for 9.07 euros per MHz POP in Spain, but a whopping 0.51 euros per MHz POP in Italy. U.K. spectrum sold for 0.17 euros per MHz POP.

On the other hand, at least one Australian official worries that a recent big merger between TPG and Vodafone will reduce demand and lead to lower prices.

One might simply argue that supply and demand will  work. Whatever the limits on new spectrum at 3.5 GHz, regulators simply must make more spectrum available in other bands. More supply takes care of pricing pressures. Releasing more unlicensed spectrum, spectrum sharing, spectrum aggregation and additional spectrum in the millimeter wave bands all will help ensure there is plenty of 5G spectrum and that prices will not be onerous.

Supply in the 3.5-GHz auctions will be something of an issue, in most countries, as there is not lots of spectrum available there.

source: GSMA

French regulator Arcep’s chief Sebastien Soriano announced it will be challenging to keep prices low for a 2019 spectrum auction, especially when supply cannot keep up with demand, but said it wants to find a way to do so.

Traditional government views of spectrum auctions as easy ways to raise government revenues also are issues. Policymakers have to balance the need to make lots of spectrum available with the desire to raise revenues.

As you would expect, firms that have paid high prices justify their actions by arguing the new spectrum will help reduce costs per gigabyte, as well as supporting all the new end user demands for capacity.

High spectrum prices, though, have been big problems for mobile operators. Recall the high prices paid for 3G spectrum in many countries, which nearly bankrupted several firms in Europe, the high prices paid in India and in some other countries.

More supply will help keep prices within reasonable ranges.

The deadline to apply for one of the PTC Innovation Awards is Nov. 2, 2019.

How Much 5G Mobile Substitution?

AT&T is preparing to launch commercial 5G mobile service using millimeter wave spectrum and the NETGEAR Nighthawk 5G Mobile Hotspot.

AT&T says the device is the first standards-based mobile 5G device in the world able to access a live millimeter wave 5G network.

At least in principle, the use of a 5G hotspot, on a millimeter wave network,  with retail pricing plans that are comparable to a fixed network plan, allow a mobile 5G network to compete with fixed networks.

As a practical matter, that might not happen in ways that make mobile 5G an effective substitute for fixed service. As has been the case for 4G, some users will find 5G a functional substitute; others will not. In the 4G era, perhaps 20 percent of U.S. households are mobile only for internet access.

And at least some observers believe such mobile substitution could reach 30 percent to 40 percent by about 2022.

67% Use Connected Devices; 64% Say They Do Not Depend on Them

Even though 67 percent of people surveyed by Clutch own a connected device such as a smart refrigerator, oven, or TV. But 64 percent say they do not depend on their connected devices to accomplish daily activities, a survey by Clutch has found.

On the other hand, 64 percent of people use their connected devices daily, typically to access important personal information regarding health, home, and news.

Nearly 40 percent of those surveyed say access to important information is the primary benefit of using a connected device, Clutch says.

Some 36 percent say they do depend on their devices to get through their daily lives. About 35 percent own a wearable device and 27 percent own a digital assistant such as a Google Home or Amazon Echo.
