Reality Check: 5G – the history of the future

Over 50% of the world’s LTE subscribers today are in the U.S. With its aggressive 4G deployments aided by the thriving application ecosystem, the U.S. was able to wrestle back the leadership mantle of the mobile world.

While consumers are enjoying their mobile broadband devices and services, chatter around “5G” has begun. Some new to the industry might be perplexed by all the talk of a technology cycle that is years away, however, if we study the 35-year-old history of the mobile industry, things are going according to plan.

All the major mobile markets have started to focus on defining 5G and the subsequent launch dates. Even Europe, which still has a long way to go before its 4G networks are built out, has set its sights on 5G to recapture the mantle and the pride of the GSM days. Korea and Japan led the world in 3G, but lost the lead of 4G to the U.S., but both countries are eager to be considered leaders in 5G. The Japanese government has set the ambitious goal of having 5G before the Tokyo Olympics in 2020 (Russia wants it by 2018 for the FIFA World cup). U.S regulators have also started to talk about 5G and the future spectrum needs as well.

Students of the industry will observe that these network technologies evolve over a 20-year cycle. In general, the time to peak – the point at which the net revenue for the technology peaks and starts dropping – is generally slower than the time from peak to sunset. This is primarily because as the last generation is peaking, investments and rollouts of the new generation of technology start, taking away the share at a faster pace. On average, the time-to-peak has been 12 years, while the time from peak-to-sunset has been seven years. Obviously, there are shifts in different countries – depending on spectrum auctions, competitive dynamics and investment availability – but they largely follow the 20-year cycle.

For each of these 20-year cycles, the research and development, and standardization time period of seven to eight years typically precedes the first major deployments of the network technology. So overall, these are big cycles of 25 to 30 years from initial concepts to the last subscription leaving the network technology. The research work for 5G got started in 2012, and we might have our first networks by 2018-2020.

While there is no consensus yet on what 5G will feel and look like, there is some agreement on the types of performance criterion that are worth considering. Some of the performance goals for 5G under discussion are:

• Average speeds of between 500 megabits per second, up to 10 gigabits per second
• Less than 1 millisecond latency
• (Almost) 100% network coverage
• 1,000 times reduction in power consumption
• Very high reliability in all circumstances especially indoors (99.999%)
• Deep indoor coverage (+20dB)
• 30 times higher device density
• 10 to 100 times as many connected devices
• Significantly higher security requirements

The first four generations have largely followed the same business model, that of “metering.” The operator typically invested in assets such as spectrum, network build-out, operational capacity, etc., and then built the business based on the usage. In the early days, it was more of a linear model with a tight correlation between the usage and the cost of the usage, but as the markets matured, the past revenue curves melded into the new ones. That’s the reason voice and messaging are offered as unlimited packages designed around the data services.

Will 5G offer new business models, or explore a different relationship between usage and cost? Will consumers warm up to the idea of value-based pricing? Or, will access just become a commodity layer like water and electricity with most of the value residing in the platform and application layers? Although we have started to see the shifts, how fast will the future accelerate? Will the ecosystem landscape be markedly different from what we have in place today? These questions will be answered in due course.

Another important question for the industry will be around the control points. From 1G to 3G, the industry clearly revolved around the operators. Almost all of the revenue in the industry flowed through the operators, which controlled more than 75% of the industry revenue. However, primarily because of the broadband capability of the networks, the emergence of the powerful computing platforms in Apple’s iOS and Google’s Android, and the very powerful computing devices they power, the picture in the 4G era is changing. We estimate that the overall control of the industry revenue by the operators will shrink to 50% or lower within the next five years. That doesn’t mean operator revenue will decline in aggregate as we think they will continue to increase 1-3% globally. But, the ecosystem is growing much faster and, as such, the operator share will decline.

With 5G, it is very likely that a highly distributed application and services ecosystem will become the dominant industry source of revenue around which the rest of the mobile solar system will evolve. The tectonic shifts are likely to result in fewer mobile operators in the 5G technology era. Most countries will have two or three major operators, and since so much mobile traffic is indoors, we will see the wireline and wireless operators merge at a frantic pace in the next five years. Many will also become content owners, banks and might even operate car companies. On the flip side, we might see the rise of nontraditional mobile virtual network operators wherein vertical industry players will bundle IP access with their services.

The noise around 5G will only grow louder in 2015, but that is normal. All mobile network technology evolutions have gone through the same cycle in the last 35 years and 5G will be no different. However, the ecosystem and the control points in 2025 are likely to look markedly different from the first three cycles. Tighten your seat belts and enjoy the ride.
