The non-stop wireless industry claims that we’ve moved from 4G to 5G finally slowed to the point that I stopped paying attention to it during the last year. There is an interesting article in PC Magazine that explains why 5G has dropped off the front burner.

The article cites interviews with Art Pouttu of Finland’s University of Oulu about the current state and the future of 5G. That university has been at the forefront of the development of 5G technology and is already looking at 6G technology.

Pouttu reminds us that there is a new ‘G” generation of wireless technology about every ten years but that it takes twenty years for the market to fully embrace all of the benefits of a new generation of wireless technology.

We are just now entering the heyday of 4G. The term 4G has been bantered around by wireless marketing folks for so long that it’s hard to believe that we didn’t see a fully-functional 4G cell site until late in 2018. Since then, the cellular companies have beefed up 4G in two ways. First, the technology is now spread through cell sites everywhere. But more importantly, 4G systems have been bolstered by the addition of new bands of cellular spectrum. The marketing folks have gleefully been labeling this new spectrum as 5G, but the new spectrum is doing nothing more than supporting the 4G network.

I venture to guess that almost nobody thinks their life has been drastically improved because 4G cellphone speeds have climbed in cities over the last few years from 30 Mbps to over 100 Mbps. I can see that faster speed on my cellphone if I take a speed test, but I haven’t really noticed much difference between the performance of my phone today compared to four years ago.

There are two major benefits from the beefed-up 4G. The first benefits everybody but has gone unnoticed. The traditional spectrum bands used for 4G were getting badly overloaded, particularly in metropolitan areas. The new bands of spectrum have relieved the pressure on cell sites and are supporting the continued growth in cellular data use. Without the new spectrum, our 4G experience would be deteriorating.

The new spectrum has also enabled the cellular carriers to all launch rural fixed cellular broadband products. Before the new spectrum, there was not enough bandwidth on rural cell sites to support both cellphones and fixed cellular customers. The many rural homes that can finally buy cellular broadband that is faster than rural DSL are the biggest winners.

But those improvements have nothing to do with 5G. The article points out what has always been the case. The promise of 5G has never been about better cellphone performance. It’s always been about applications like using wireless spectrum in complex settings like factories where feedback from huge numbers of sensors needs to be coordinated in real-time.

The cellular industry marketing machine did a real number on all of us – but perhaps most of all on the politicians. We’ve had the White House, Congress, and State politicians all talking about how the U.S. needed to win the 5G war with China – and there is still some of that talk going around today. This hype was pure rubbish. What the cellular carriers needed was more spectrum from the FCC to stave off the collapse of the cellular networks. But no cellular company wanted to crawl to Congress begging for more spectrum, because doing so would have meant the collapse of cellular company stock prices. Instead, we were fed a steady diet of false rhetoric about how 5G was going to transform the world.

The message from the University of Oulu is that most 5G features are probably still five or six years away. But even when they finally get here, 5G is not going to bring much benefit or change to our daily cellphone usage. It was never intended to do that. We already have 100 Mbps cellular data speeds with no idea how to use the extra speed on our cellphones.

Perhaps all we’ve learned from this experience is that the big cellular companies have a huge amount of political and social clout and were able to pull the wool over everybody’s eyes. They told us that the sky was falling and could only be fixed with 5G. I guess we’ll find out in a few years if we learned any lesson from this because we can’t be far off from hearing the hype about 6G. This time it will be 100% hype because 6G deals with the use of extremely short frequencies that will never be used in outdoor cellular networks. But I have a feeling that we’ll find ourselves in a 6G war with China before we know it.
