5G: Another Next-Generation Disappointment?

The telecom industry likes using the word "cyclical" to describe the ups and downs it experiences as new technologies are introduced. But when it comes to the narrative that accompanies this process, "recycling" might be more apt. With a few variations, the story has become all too familiar: A next-generation technology hoves into view, is quickly heralded as a game-changer and ultimately underwhelms. The 5G standard now generating reams of hype could prove the biggest anticlimax of all.

That it will disappoint seems inevitable following so much publicity and the precedent set by previous standards. A genuine game-changer, 3G ushered in the mobile Internet but could not cope with traffic demands. The subsequent 4G standard merely rectified that problem, bringing nothing more than additional speed (to some observers, 4G is simply 3G made good).

It would be curmudgeonly to suggest these technologies have been unimportant. The mobile Internet has underpinned the smartphone revolution, with huge implications for the way people live and work. It has fueled the growth of the digital economy and propelled digital pioneers like Uber, a ride-hailing app service that has turned the taxi business upside down.

But it is players outside the telecom industry that have garnered the rewards and recognition. While sales of smartphones have soared, and Uber's roster of drivers has lengthened, telco revenues have stubbornly refused to grow, in many cases, and often been in decline. In the UK, service revenues generated by mobile giant EE (now a part of fixed-line incumbent BT Group plc (NYSE: BT; London: BTA)) fell from £6.2 billion ($7.5 billion) in 2011, the year before its 4G launch, to £6 billion ($7.3 billion) in 2015. This was despite a move into the fixed broadband and TV markets over that period. Consumers treasure their devices but have scant regard for the networks that connect them.

This never-ending story could darken with the launch of 5G in the 2020 timeframe. From a consumer perspective, the forthcoming technology will bring about further -- albeit dramatic -- improvements in connection speeds, putting it on a serious footing with some advanced fixed-line technologies. It will also lead to a reduction in network latency, or the delay that occurs during data downloads. As with 4G, these features should support the use of more advanced data services, such as Ultra HD video. But customers already enjoying a high-quality audiovisual experience on 4.5G networks will notice few extra benefits from 5G. What's more, many of the services that consumers really value on the move, such as Uber, do not require high-speed or low-latency connections. (See 4.5G Sets High Bar for 5G.)

John Strand, an analyst at Strand Consult and one of the industry's more outspoken commentators, is typically gloomy about 5G for such reasons. "People will likely recognize that most 5G services can run on 4G networks," he writes in a set of predictions for 2017. "The change from 4G to 5G will not be as dramatic as the jump from 3G to 4G."

Experience also suggests that higher speeds will not spur any kind of sales growth. "We have been increasing the data bucket since the launch of 4G and yet the revenue trend is negative and has been declining since 2008," says Bengt Nordström, the CEO of the Northstream market research and consulting business. "Launching 5G doesn't mean revenues will increase but it might help operators to keep their customers."

Indeed, while Nordström believes mass deployments are about six years away, competitive pressure will sooner or later spur operators to invest in 5G networks for consumers. Yet much of the 5G interest lies elsewhere -- in enterprise customers and public sector organizations that are digitalizing their products and services. The low latency that comes with 5G could take a car company or healthcare provider into uncharted territory, and positions 5G for a much-vaunted role in the so-called Internet of Things (IoT). "Low latency is the biggest driver [of 5G]," said Sami Elhage, the president of mobile networks for Nokia Corp. (NYSE: NOK), during a recent press briefing in London. "Capacity you can play with in 4G." (See 5G Guru Predicts Rollout Disparity and Nokia: A Global Network Operator for the Enterprise?.)

Re: Plus a change Well I suppose you could argue that 4G is just now starting to live up to its speed promises. But yeah, absolutely not a disappointment, it has revolutionized how many people interface with the world. Will 5G do that? It very well might, but we can't say that yet. Nobody can be sure of that yet!

Re: Plus a change I agree more with @danielcawerey. 4G-LTE is an incredible technology -- absolutely not a disappointment. So another disappointment doesn't scan.

With repect to 5G, I think you need to frame the "diasppointment" more clearly. Are my fellow pundits talking in terms of operator revenues? Tech perfromance? End-user experience? Overall value to industry or society?

Or are these just general comments that 5G will be hard to develop and the industry revenue structure has challenges? If so, we hear that every time there's a new generation.

Sending out a VR video stream Sending out a VR video stream to your buddies via a head-mounted camera will be a lot like flying a F-35 and having another F-35 pilot being able to see all around your plane.

It gives a new meaning to the old term "I've got your back, buddy."

Now that's a killer 5G app.

It All Starts with XHaul I agree with much of what's been said.  I mean really.... how much of an improvement is the visual experience of a 4K Ultra HD movie on a 3.5-inch screen?  Virtual reality will eventually take advantage of the increased bandwidth 5G is selling, but the infrastructure has to be there first.  And that's the sticky wicket of the whole thing.  Telcos are going to encounter the cross-over where the cost-per-bit is going to exceed the revenue-per-bit soon.  Laying out millions of dollars for another infrastructure upgrade seems absurd but yet must be done to keep up with the Jones' and appear relevant.  So the telcos have a HUGE interest in 5G and its fixed wireless xhaul.  They need to reduce capital expenditures to the core by eliminating costly fiber installation.  Once that is solved, the densification of the network (most of it indoors), MEC, the great new apps, etc., etc., will all fall in place.  But it will all have to start with the xhaul.

Not a tech problem The problem for SPs is not technological, it's economic. Consumers view telco service as overpriced and customer service as shoddy. Telcos need more revenue to deliver better service. Nobody wins at that game.

Enterprise service such as IoT seems to be a more promising area for both. Businesses are more willing to pay for what they need.

Re: Plus a change I think 4G has made a huge difference. It's created new categories of apps that couldn't exist previously. There would be no Snapchat without 4G, that's for sure. 

Plus, anyone here ever been caught in a 3G zone? It's like taking your smartphone back to 2007. Not a fun time.

Re: Plus a change I question some of the conclusions from the august panel of experts cited in this post. True 5G will be more than "faster" 4G. As our own Gabriel Brown has noted, 5G will underpin a vastly different mobile communications environment. The label has been co-opted by marketers -- surprise surprise -- who simply can't help themselves. So, yes, early versions of 5G will be disappointing, because they really won't be true 5G.

Plus a change When *isn't* a next-gen network a disappointment? The xG is not what sells a network. It's a device or application that people really want that runs on it. Maybe it will be a 5G VR gadget, who Knows?
