But I look around my own part of the world and I have a hard time seeing this kind of impact. I live in a town of 90,000 people. If we are like the average US market then roughly 85% of homes here already have landline broadband. Practically everybody here also has a cellphone, with the majority using smartphones.
People may read my blog and think I am not a fan of 5G – but that’s not true, I’m just not a fan of the hype. I would love for Verizon to offer me another choice of home broadband – I would consider changing to Verizon at the right price, as would many other households. My biggest question is how much value Verizon would create by introducing 5G in my town. Let’s say Verizon was to capture 30% of the broadband market here – that certainly creates an advantage to Verizon and gives them a significant new revenue stream. However, for every customer Verizon gains, Charter or AT&T would lose a customer, and overall that’s a zero-sum game. Further, if you assume that 5G competition would drive down prices a bit (it might not since oligopolies tend to not compete on price), then the overall spending on broadband in the town might actually decrease a bit.
The same thing would happen with cellular 5G. The big four cellular companies will have to spend a lot to upgrade all of the cell sites here to 5G. We’re a hilly and heavily wooded City and it will take a lot of small cell sites just to fill in the existing cellular holes. But unless they can find a way to charge more for 5G cellular broadband, then cellphone broadband is also a zero-sum game. Everybody in town already has a cellphone and a data plan, and the long-term trend is for cellular data prices to drop. I don’t see the new revenue stream from 5G cellular that will pay for the needed upgrades. Perhaps faster cellular data speeds will attract more people to drop landlines, but that’s also a zero-sum for the market as a whole.
There is one new aspect of 5G that the cellular carriers are counting on to create a new revenue stream. Once the 5G technology has been developed, the 5G standard calls for the ability of a cell site to communicate with as many as 100,000 devices – a huge increase over today’s capabilities. The cell carriers are clearly banking on IoT as the new revenue opportunity.
However, that kind of transition isn’t going to happen overnight. There are a whole lot of steps required before there is a huge cellular IoT revenue stream. First, the technology has to be developed that will handle that huge number of IoT devices. The 5G core standards were just developed last year and it will take years for vendors and labs to achieve the various goals for 5G. As those improvements are realized it will take a lot longer to introduce them into the cellular networks. We are just now finally seeing the deployment of 4G LTE – AT&T is just now deploying what they call 5G Evolution into any major markets, which is actually fully-compliant 4G LTE. The same slow roll-out will occur with 5G – we’ll advance through 4.1G, 4.2G, etc. until we see fully-compliant 5G network in a decade.
We’ll also have to wait for the rollout of IoT sensors that rely on a 5G network. It will be a bit of a chicken and egg situation because nobody will want to deploy devices that need 5G until 5G is active in a sufficient number of neighborhoods. But eventually this will come to pass – to a degree we can’t predict.
The question is if IoT usage is the trillion-dollar application. I certainly look forward to a time when I might have an embedded chip for 24/7 health monitoring using a 5G network – that’s a service that many people will be willing to pay for. But there is no guarantee that the revenue streams will materialize for IoT monitoring to the extent envisioned by AT&T and Verizon. I’ve done the math and the only way that the carriers can see a trillion-dollar benefits from IoT is if future homes have an IoT monitoring bill of the same magnitude as our current cellular or broadband bills – and that may never come to pass. I would love to see a concrete business plan that predicts where these huge new benefits come from, but I’ve seen nothing specific other than the big claims.
There is one aspect of the hype that I do buy. While I can’t see any way to equate the value of 5G to be as important as electricity, it is likely to share the same kind of introduction cycle that we saw with the electric grid. It took 25 years for electricity to spread to the majority of US cities and another 25 years until it was in most of rural America. New technologies today deploy faster than the deployment of electric grids – but this still can’t happen overnight and is at likely to be many years until rural America sees 5G cellular and a lot longer for 5G fixed broadband.
If you believe the hype in the press, we’ll start seeing big benefits from 5G in 2019 and 2020. I can promise you a blog at the end of next year that looks to see if any of this hype materialized – but I already suspect the answer will be no.
