A hydrant in Chengdu has a SIM card
By: Robert Sterling – SeaPRwire – Somewhere in Chengdu there is a fire hydrant that reports for duty every morning. It sends a short packet through a carrier’s network, several times a day, saying in effect that it is still a hydrant, still upright, still where the map says it is. The electricity meter in the same stairwell does something similar. So does the lift, the shared bicycle locked to the rack outside, and the parcel locker by the gate that has started charging tenants for the fourth hour of storage.
None of these objects has a voice plan. None of them streams video. Each of them holds a SIM card and each of them counts, in the regulator’s arithmetic, as a connection.
By the end of 2025 the three carriers in China (Mainland) — China Telecom, China Mobile and China Unicom — reported 2.888 billion cellular IoT terminal users, a net increase of 232 million over the year. That figure now exceeds the 1.061 billion mobile phone users on the same networks. Machines outnumber people on the Chinese mobile network by something close to three to one, and the ratio is still widening. IoT connections make up 61.3% of every terminal connected to those mobile networks.
This is the part of the story that never makes the press conference. The other part does: 5G base stations, gigabit fibre, computing hubs in the interior. Both parts are true, and they are true in the same year, and only one of them moves revenue.
The 9.1% and the 0.7%
Here are the two numbers the Ministry of Industry and Information Technology put at the top of its 2025 telecommunications statistics bulletin, released in late January 2026.
Telecommunications service volume — a quantity index, roughly a measure of how much traffic and how many connections the system carried, weighted and deflated — rose 9.1% year on year.
Telecommunications service revenue rose 0.7%.
Read those two lines next to each other for a while. Nine point one against zero point seven. A network that carried almost a tenth more of everything it carries, and brought in well under one percent more money for doing it. (The carriers will point out, reasonably, that volume and revenue measure different things, and that a deflated volume index is not a price. It is still a fairly stark pair of numbers to publish about yourself.)
This gap is not a Chinese peculiarity. Every operator in every market that built out fibre and 5G in the 2020s is living inside some version of it. What is distinctive about China (Mainland) is the scale at which the gap is now running, and the frankness with which the regulator puts both figures in the same bulletin.
The practical consequence lands on the capital side. If traffic grows at high single digits and revenue grows at a rounding error, then the return on the next base station is not the return on the last one. The engineering answer has been to chase cost out of the network. The commercial answer, so far, has been to sell connectivity in units nobody would have recognised as a product in 2015: a hydrant check-in, a lift diagnostic, thirty seconds of video from a dashcam.
Where the base stations sit
The build-out did not slow down. At the end of 2025 the country had 12.87 million mobile base stations in total, up 227,000 on the year. The split inside that number is more interesting than the total.
- 5G base stations: 4.838 million, a net addition of 588,000, now 6% of all mobile base stations, up four percentage points on the year.
- 4G base stations: 7.192 million, up only 80,000. 4G is still the larger single technology by site count, and it will be for a while.
- Base stations with 5G RedCap capability: 2.064 million, equal to 7% of all 5G sites.
That last line is the one that explains the hydrant. RedCap — Reduced Capability, the industry’s own name for the cut-down version of 5G — is designed for devices that need more than a legacy IoT chip and far less than a phone. Lower bandwidth, lower power, cheaper modules, no need for the full antenna count. Rolling it out across 42.7% of the 5G estate within roughly a year of it becoming a deployment priority is the carrier’s direct answer to the margin question: if the network is going to carry 2.888 billion things, then a large share of those things should occupy the cheapest possible slice of it.
On the user side, 1.204 billion 5G mobile subscribers were counted at the end of 2025, 65.9% of all mobile phone users, up 9.2 percentage points in twelve months. The migration is far enough along that the remaining 34% is now the harder half: older devices, price-sensitive users, rural households whose 4G handset still does everything they ask of it.
RedCap, the cheaper 5G
It is worth slowing down on RedCap, because it is the clearest example of how the Chinese network shifted from a consumer build to an industrial one.
A full 5G module in a sensor is absurd. You do not need multi-gigabit downlink to tell a district heating utility that a valve is closed. What you do need is a module cheap enough to deploy in tens of millions, a battery that lasts years rather than days, and a network that will still be maintained in 2035. RedCap trades bandwidth and latency headroom for exactly those three things.
The numbers on the ground are straightforward. Out of 4.838 million 5G base stations, 2.064 million had been upgraded to accept RedCap devices by the end of 2025. That is not a pilot. That is a coverage decision made at national scale, and it is what makes the 28.88 million-per-year growth in IoT connections physically possible rather than aspirational.
- Meters, hydrants, lifts and shared mobility: cheap modules, tiny payloads, years of battery life.
- Dashcams and in-vehicle units: intermittent bursts, moderate bandwidth, high device counts.
- Wearables and health monitors: low duty cycle, long replacement cycles, tight power budgets.
- Factory sensors and inspection cameras: the segment that actually justifies 5G’s latency claims.
The fourth category is the one the policy documents care about, and the one that is hardest to count. The first three are the ones that show up in the connection statistics, and they show up in enormous numbers.
Fibre, 10G PON, and 74.99 million kilometres of glass
Fixed infrastructure kept the same rhythm. During 2025, 2.113 million kilometres of new optical cable were laid, taking the national total to 74.99 million kilometres. For scale, the equator is about 40,000 kilometres, so the country now has enough glass in the ground to circle it roughly 1,875 times. (This is the kind of fact that appears in every national telecom bulletin and means very little, which is precisely why it appears in every national telecom bulletin.)
The useful numbers sit under it:
- Fixed broadband access ports: 1.251 billion, up 48.77 million.
- Fibre access (FTTH/O) ports: 1.21 billion, up 50.30 million, now 8% of all broadband ports.
- 10G PON ports capable of gigabit service: 31.62 million, up 3.419 million.
- Fixed broadband subscribers: 691 million, up 20.99 million.
- Subscribers on 1000 Mbps or faster: 238 million, up 31.57 million, 5% of all fixed broadband users.
Copper is functionally finished as an access technology. At 96.8% fibre ports, the remaining 3.2% is legacy estate being retired rather than a competing platform.
The gigabit number deserves a second look. Thirty-one point six million 10G PON ports serve 238 million gigabit subscribers, which is a ratio of roughly 7.5 subscribers per port — a reasonable split ratio for passive optical networking, and one that suggests the port build is running slightly ahead of subscriber demand rather than desperately behind it. Growth of 31.57 million gigabit subscribers in a year, against 20.99 million total broadband subscriber growth, means the gigabit tier is now where essentially all fixed broadband growth happens. People are not joining; they are upgrading.
Eight hubs, five of them in the west
The computing side is where national policy became physical concrete. The “East Data, West Computing” programme, known in Chinese as dongshu xisuan, was designed to move data processing away from the coastal provinces that generate it and toward the interior provinces that have cheap land and, more importantly, cheap electricity.
Eight national computing hub nodes were designated. Five of them are in the western region. The logic is not subtle: a training cluster or a cold-storage archive does not need to sit next to its users, it needs power that costs less and does not brown out in August, and land that a coastal municipality would rather use for something with a higher tax yield.
By mid-2025, the National Data Administration was reporting total computing capacity as second in the world by scale, alongside a claim about the geographic distribution that matters more than the ranking: interior nodes were taking a growing share of new capacity, and the coastal provinces were, for the first time, not the default answer to “where does this data centre go”.
Across the three carriers, 938,000 data centre racks were in service and offered externally at the end of 2025, up 108,000 on the year. That is a growth rate of about 13% in rack count, in a year when service revenue grew 0.7%. The description in the ministry’s own bulletin is revealing: the carriers’ focus has shifted from “broad coverage” to “deep integration”, from selling basic cloud resources to selling scheduling, and from building racks to making the racks they already have work together.
That shift is a margin story. Racks are capital. Scheduling is software. If you can sell the same rack twice by filling its idle hours, you do not need to build as many racks.
Racks, power, and the bill that arrives later
There is a cost to all of this that the connection statistics do not capture.
A 938,000-rack estate draws a great deal of electricity, and in China (Mainland) it draws it from a grid that is simultaneously absorbing an enormous build-out of solar and wind. The interior hubs were sited for cheap power, but “cheap power” in a province that is also industrialising fast is a moving target. Several western hub sites have already had to plan substation capacity alongside rack capacity, which is the sort of detail that turns a two-year project into a four-year one.
The second cost is the one that arrives later: depreciation. A base station built in 2020 is on a different depreciation clock from a RedCap upgrade installed on it in 2025, and a rack commissioned in a hub in 2023 is competing with racks commissioned in 2025 that are denser, better cooled and cheaper to run. The carriers’ capital budgets have to absorb both, and the revenue line grows at 0.7% while they do it.
- Network traffic and connections: up sharply, and the volume index says 9.1%.
- Revenue per unit of traffic: down, and the revenue line says 0.7%.
- Capital intensity: still high, because coverage commitments do not expire.
- Power and land: the input cost that the western hubs were supposed to solve, and partly have.
Put those four together and you get the actual strategic problem of Chinese telecom in the late 2020s. It is not a coverage problem and it is not a technology problem. It is the problem of an industry that has built something extremely good and has not yet found a way to charge for it in proportion to how good it is.
The west connected faster than the east
One regional detail in the bulletin deserves more attention than it got.
Gigabit subscriber penetration at the end of 2025, by region:
- Western region: 36.1% of fixed broadband users, up 4.4 percentage points.
- Eastern region: 34.6%, up 3.4 points.
- Central region: 33.9%, up 2.7 points.
- North-east region: 29.0%, up 5.4 points.
The west leads the east on gigabit penetration, and gained faster. There is a mundane explanation: the western provinces were starting from a lower base, and new build is cheaper to do at gigabit than upgrading an estate that already has copper-era plant in it. There is also a policy explanation, which is that the same programme that put five of eight computing hubs in the west has been pushing fibre and transmission spending there for several years.
Revenue, though, has not followed capacity eastward. Telecom service revenue share by region in 2025: eastern 50.9%, western 24.3%, central 19.7%, north-east 5.1%. The Yangtze River Delta on its own accounts for 23.2% of national telecom revenue; the Beijing-Tianjin-Hebei region, 9.1%.
So the network that is being built fastest is, in relative terms, being built where the money is thinner. That is a defensible national policy and a difficult commercial one, and the tension between the two is not going to resolve on its own.
Who pays for a network that keeps getting cheaper
Follow the money and the answer is: industry, mostly, and increasingly industry that is not telecom.
The 5G applications that show up in the ministry’s framing are industrial — connected factories, port automation, mining, grid inspection, and the “5G + industrial internet” category that has been in every five-year document since 2019. These are the applications that justify the latency and the slicing, and they are also the applications that require someone other than a carrier to do the integration work.
That is where the revenue shows up, if it shows up at all: not in the access charge, but in the system integration contract, the platform fee, the maintenance agreement. The carriers have spent a decade becoming very good at building networks and are now trying to become credible at selling everything wrapped around them, which is a different business with different margins and different competitors.
For the consumer side, the picture is simpler and less comfortable. Prices have fallen, speeds have risen, and 65.9% of mobile users are on 5G. Almost none of those users is paying a premium for it. The upgrade was absorbed into existing plans, which is exactly what the 9.1%-versus-0.7% pair describes from the other end.
1.19 billion HarmonyOS devices and 60% of AI patents
Two more figures from the same August 2025 State Council briefing are worth holding carefully, because both are large and both need a definition attached.
The first: the HarmonyOS ecosystem passed 1.19 billion devices, spanning more than 1,200 product categories — phones, cars, appliances, and a long tail of things that used to ship with a proprietary little operating system nobody updated. That is a genuine installed base, and it is the largest single piece of evidence that the country has an alternative client platform with real scale.
The second: 60% of the world’s artificial intelligence patents. This one is more slippery. Patent counts depend entirely on which office you count, whether you count applications or grants, and whether a family counts once or once per jurisdiction. Sixty percent of global AI patent filings is a defensible statement about filing behaviour at the national office. It is not a statement about who has the best models, and the briefing did not claim it was.
The reason both numbers belong in an article about telecom infrastructure is the same reason RedCap belongs in it. The build-out was never only about access. The stated goal, repeated across four years of policy documents, has been a domestic stack: domestic chips, domestic operating systems, domestic models, running on domestic networks, sold to domestic industry.
- Access layer: 4.838 million 5G sites, 1.21 billion fibre ports, 31.62 million 10G PON ports.
- Device layer: 1.19 billion HarmonyOS endpoints, 1.204 billion 5G subscribers.
- Compute layer: eight national hubs, five in the west, 938,000 external racks.
- Application layer: 2.888 billion IoT connections, 61.3% of everything attached to the mobile network.
Each layer is measured by a different agency, in different units, on a different schedule. That is precisely why the revenue figure is the one worth watching — it is the only number in the stack that cannot be flattered by choosing a unit.
What the bulletin declines to break out
A national statistics bulletin is a political document as well as a technical one, and its silences are informative.
There is no breakdown of IoT revenue per connection. There is no average revenue per user for the gigabit tier, only subscriber counts and port counts. There is no utilisation rate for the 938,000 racks, which is the single number that would tell you whether the western hubs are filling or standing half empty. There is no figure for how much of the 588,000 net new 5G sites were built to meet a coverage obligation rather than a demand signal.
None of these omissions is sinister. All of them are commercially sensitive, and a regulator that published them would hear about it. But a reader trying to work out whether the 9.1% versus 0.7% gap is narrowing or widening cannot do it from this bulletin alone, because the two lines that would settle it — revenue per IoT connection, and rack utilisation by hub — are exactly the two that are missing.
That leaves outside observers doing arithmetic on the numbers that are published. Divide 232 million net new IoT connections into the difference between total service revenue growth and what subscriber growth alone would explain, and you get a number with an enormous error bar and the right sign. It suggests IoT is being sold at a fraction of the per-unit revenue of a phone line, which is unsurprising, and that the fraction is not improving quickly, which matters.
Read the revenue line, not the press release
If you want to know how this goes, do not read the base station count.
Base stations are a commitment, and commitments get met. Racks are a commitment too. What is not a commitment is the revenue line, and that is where the honest information lives. Watch three things next year: whether service revenue growth climbs back above two percent, whether IoT connection growth continues to outrun any plausible growth in IoT revenue per connection, and whether the western hubs start reporting utilisation figures rather than capacity figures.
The hydrant in Chengdu will keep checking in either way. It has no opinion about any of this, which is of course the entire point of it.
