Latest / The 5G Podcast with Fexingo: Wireless Networks, Carriers, and Mobile Infrastructure / How 5G Is Quietly Transforming Agriculture
Transcript
- Lucas: A few weeks ago I was reading about a 2,500-acre corn farm in Iowa that decided to ditch its Wi-Fi-based sensor network and deploy a private 5G system instead. The results from the first full growing season just came out, and they’re pretty striking. Luna: How big of a leap are we talking — is this just a tech demo or something that actually pencils out? Lucas: It pencils out. The farm spent about 180,000 dollars on the private 5G build — that’s a small cell base station, core network gear, and installation across the entire property. They now connect over 1,200 IoT devices: soil moisture sensors, irrigation valve controllers, drone-based crop imagers, and even a pair of autonomous tractors. Luna: And what did they get in return? Lucas: A 15 percent yield increase and a 22 percent reduction in water usage. The numbers are from the farm’s own reporting, not a vendor white paper. The key driver was latency and reliability. With Wi-Fi, the sensors would drop off when they were too far from a router, and data would buffer for minutes. With 5G, everything updates in near-real time. Luna: So the precision part of precision agriculture actually works when the network doesn't hiccup. Lucas: Exactly. And this isn't an isolated case. The smart agriculture market is projected to hit 34 billion dollars by 2030, and 5G-enabled solutions are growing at a compound annual growth rate of 28 percent, according to a report from Grand View Research published earlier this year. Luna: That’s faster than most enterprise 5G use cases I’ve seen. What's driving that growth? Lucas: A few things. First, labor shortages in agriculture are acute. The USDA reported that farm employment in the US fell by 6 percent year-over-year in the first quarter of 2026. Automation is the most obvious answer, but automation requires connectivity that can keep up with moving equipment across hundreds of acres. Luna: And Wi-Fi just can't cover that kind of geography without a ton of repeaters. Lucas: Right. A typical Wi-Fi access point covers maybe 300 feet indoors. Even with outdoor mesh systems, you're looking at dozens of nodes to cover a large farm, and each node introduces latency and potential failure points. Private 5G can cover several square miles from a single small cell, with handoffs that are seamless for moving vehicles. Luna: But private 5G isn't cheap. A hundred and eighty grand is real money for a farm. Can the economics work for smaller operations? Lucas: That's the big open question. The Iowa farm I mentioned is relatively large. For a 500-acre farm, the upfront cost might be in the 60 to 80 thousand range, which is harder to justify unless you're growing high-value crops. But the carriers are starting to offer alternatives. T-Mobile, for instance, launched a dedicated agriculture connectivity service last fall that combines its public 5G network with a private network slice. Luna: So you don't have to build your own core — you buy a guaranteed slice of the carrier's network. Lucas: Exactly. Network slicing lets a farm get dedicated bandwidth and low latency without owning the infrastructure. Verizon has a similar offering called Thingspace for Ag. The pricing isn't public, but early reports suggest it's about 30 to 40 percent cheaper per device than a full private network, which could open the market to medium-sized farms. Luna: What about the other major IoT protocol for agriculture — LoRaWAN? That's been the go-to for low-power soil sensors for years. Lucas: LoRaWAN is still very relevant for simple, low-data sensors — things like temperature or humidity readings once an hour. But it can't handle high-bandwidth applications like real-time drone video or control signals for autonomous tractors that need sub-20 millisecond latency. 5G can do both on one network. That convergence is important because farmers don't want to manage two separate connectivity stacks. Luna: One network to rule them all. But there's a tension — 5G modems consume more power than LoRaWAN chips. If you're putting a sensor in a field for three years on a battery, that matters. Lucas: It does. And that's where 5G's reduced capability standard, often called nr light, comes in. It's a variant of 5G designed for IoT devices that need mid-tier data rates and longer battery life. Chipsets for nr light started shipping in volume this year, and they're expected to cut power consumption by about 50 percent compared to full 5G. That makes 5G viable for more sensor types. Luna: So the technology stack is maturing. But what about the actual equipment — tractors, combines, sprayers. Are manufacturers building 5G into their machines? Lucas: John Deere has been the most aggressive. In January 2026, they announced that all new models of their 8R series tractors would come with integrated 5G modems as standard equipment. That's a big deal because Deere has a massive installed base and they have the leverage to push the entire supply chain. CNH Industrial, which owns Case IH and New Holland, followed with a similar announcement in March. Luna: That's going to create a pull effect — when the tractor already has 5G, farmers are more likely to invest in the network to use it. Lucas: Precisely. And the use cases go beyond just driving. With 5G, a tractor can communicate with a drone overhead in real time. The drone spots a weed patch, sends the coordinates to the tractor, and the tractor applies herbicide only to that specific spot — not the whole field. That's the kind of application that saves money and reduces chemical usage. Luna: We should talk about drones more. That's a use case where 5G's uplink speed really matters. Lucas: Absolutely. A high-resolution multispectral camera on a drone generates a lot of data — a single pass over 100 acres can produce several gigabytes. With 4G or Wi-Fi, you'd have to land the drone and offload the data physically. With 5G, you can stream that data to a cloud-based AI model while the drone is still in the air, and get back actionable maps minutes later. Luna: And that speed means you can adjust irrigation or fertilizer application on the same day, not the next week. Lucas: Right. One of the farms I read about in Nebraska uses a 5G-connected drone to generate normalized difference vegetation index maps every three days. They cross-reference that with soil sensor data and adjust water flow to individual irrigation pivots within hours. They reported a 30 percent reduction in water use compared to their previous weekly scouting schedule. Luna: That's impressive. But I wonder about the data side — who owns all that agronomic data? The farm, the carrier, or the equipment manufacturer? Lucas: This is a real tension point. John Deere has historically been protective of the data generated by its machines. However, under pressure from farmer advocacy groups, Deere announced a new data-sharing framework in February 2026 that gives farmers explicit control over who can access their data and for what purpose. But for smaller carriers and startups, the data ownership question is still murky. Luna: And that could slow adoption if farmers don't trust the ecosystem. Lucas: It already has. A survey from the American Farm Bureau Federation in April 2026 found that 43 percent of farmers cited data privacy as a major barrier to adopting connected farming technologies. That's down from 51 percent the year before, so trust is improving, but it's still the second most cited barrier after cost. Luna: Speaking of barriers — what about coverage? Even if a farmer wants 5G, if they're in a rural area where the carrier hasn't deployed mid-band spectrum, they're stuck. Lucas: That's a real limitation. T-Mobile has the best rural 5G coverage because of its 600 MHz spectrum, which travels farther. But even they don't cover every farm. Verizon and AT&T are still catching up. For farms in deep rural areas, private 5G on CBRS spectrum, which is the 3.5 GHz band licensed for shared use, is actually more feasible because the farmer can deploy their own network without needing a carrier's macro tower nearby. Luna: CBRS has been a game changer for enterprises. It's interesting to see it become a bridge for agriculture. Lucas: And the FCC made it easier in late 2025 by lowering the licensing fees for small-scale CBRS deployments. That cut the cost of a private 5G network on CBRS by roughly 15 percent, according to some analysts. It's not a huge savings, but it's a step in the right direction. Luna: So where do you see this going in the next couple of years? Is 5G in agriculture going to be a niche or the norm? Lucas: I think it will become the norm for larger farms — say, over a thousand acres — within five years. The economics are already there for high-value crops like corn, soybeans, and cotton. For smaller farms, it will depend on whether carriers offer affordable network slicing plans or if equipment manufacturers bundle 5G connectivity into the cost of the machinery. Luna: And on the regulatory side, any policies that could accelerate this? Lucas: The USDA's Rural Utilities Service launched a pilot program in March 2026 that provides grants covering up to 50 percent of the cost of private 5G networks for farms in underserved areas. The initial budget is 20 million dollars, which is modest, but it's a signal that the government sees connectivity as infrastructure, just like roads and electricity. Luna: That's a smart framing. Because you can't have precision agriculture without precision connectivity. Lucas: Exactly. And if the pilot proves successful, there's already talk of expanding it in the next farm bill, which is due in 2027. So there's momentum. Luna: It's one of those rare cases where the technology, the economics, and the policy incentives are all pointing in the same direction. Lucas: Yeah. And you know, conversations like this one — where we dig into a specific case and the numbers behind it — that's exactly what we try to do on this show. We're able to do it because we keep the podcast free of ads and sponsors. No commercials, no pitches, just the story. Luna: And that's a choice we make deliberately. If you find value in that approach, and you'd like to support it, there's a simple way: buy me a coffee dot com slash fexingo. Lucas: It's not expected, but it helps us keep doing episodes like this one. No pressure at all. Luna: Alright, back to the fields. So we've got the Iowa farm, the Nebraska drone example, and the policy push. What's the one thing a listener should take away from all this? Lucas: That 5G in agriculture isn't a futuristic concept — it's happening now, with measurable ROI. The technology is moving from early adopters to the early majority, driven by real yield and cost savings. And it's going to reshape how we think about farming. Luna: And probably how we think about 5G, too. Most people associate it with faster video streaming, but the most impactful use cases might be in places we never see. Lucas: Exactly. The next time you see a cornfield, there might be a 5G signal running under it.
