Transcript
- Lucas: So last week I was reading through John Deere's latest quarterly call, and one number jumped out at me: they now have over six hundred thousand connected machines in the field, generating about half a million data points per hour per combine. Luna: Half a million per hour? That's insane. What are they actually measuring? Lucas: Everything. Soil moisture, nitrogen levels, crop density, engine diagnostics, GPS coordinates down to the centimeter. But here's the thing—none of that data matters if you can't move it. And in rural America, you often can't. So Deere quietly partnered with SpaceX to use their satellite network, and they're building custom 5G antennas for combines and tractors. Luna: Wait—5G on a tractor? I thought 5G was all about dense urban cells and mmWave. How does that work in a cornfield in Iowa? Lucas: Great question. The 5G they're using isn't the high-frequency millimeter wave you see in cities. It's the mid-band and low-band spectrum, which travels farther and penetrates better. And they're combining it with satellite backhaul. So the tractor itself becomes a network node—it can relay data to other machines, and the whole fleet acts like a mesh network. Luna: So instead of each tractor needing its own direct connection to a tower, they share the link. That's smart. Lucas: Exactly. And the latency is good enough for real-time decision making. If a sensor detects that a patch of soil is drier than expected, the irrigation system adjusts within seconds, not hours. Deere claims this can reduce water usage by up to thirty percent in some trials. Luna: Thirty percent is huge. But I wonder—who actually owns the data? Is it the farmer, or does Deere keep it? Lucas: That's become a contentious issue. Deere's terms of service have evolved, but historically the farmer licenses the data back to Deere for analysis. The company aggregates it to improve their algorithms. Some farmers are pushing back—they want full ownership. There's actually a Right to Repair bill in several states that also touches on data rights. Luna: Makes sense. If your entire farm's yield data is the asset, you'd want to control it. Lucas: Right. Now, the bigger picture: this isn't just about big agribusiness. Startups like Arable and Farmers Edge are selling affordable soil sensors that run on 5G IoT networks—the kind that uses the same spectrum but with very low power. A sensor can run for three years on a single AA battery. Luna: Three years? That's wild. So a small farm could deploy a hundred sensors for a few hundred dollars and get real-time data. Lucas: Exactly. And the 5G network handles the uplink efficiently because the data packets are tiny—just temperature, moisture, pH. The whole farm might generate less than a megabyte per day. That's the opposite of the video-streaming use case, but it's just as important. Luna: I'd love to see how this affects the labor shortage. We keep hearing that farming is aging out—the average farmer in the US is over fifty-five. Lucas: That's the demographic driver. The USDA says the number of farmworkers fell by about fifteen percent over the last decade. Automation is filling the gap. With 5G, you can remote-monitor a fleet of autonomous harvesters from a tablet in your office. Some farms are already running fully driverless combines for certain tasks. Luna: But isn't that still limited to large, well-capitalized farms? The upfront cost of a connected combine is over half a million dollars. Lucas: You're right. The economics work best for operations above a thousand acres. But there's a cooperative model emerging—smaller farms share access to a connected machine through a local ag retailer. That retailer pays for the 5G connectivity and the machine, and multiple farms book time. It's like a Uber for harvesters. Luna: That's clever. So the network cost gets spread out. Lucas: Yeah. And the 5G carriers are starting to notice. T-Mobile announced a rural 5G initiative last year specifically targeting agricultural zones. They're offering flat-rate unlimited plans for farm equipment that bypass the usual per-device fees. Verizon has a similar program through their IoT subsidiary. Luna: How's the coverage? I've driven through the Midwest—there are huge dead zones. Lucas: That's the bottleneck. Even with low-band 5G, the tower density in rural areas is sparse. That's why the satellite component from SpaceX is so critical. Starlink now covers most of the continental US, and they've partnered with T-Mobile to offer direct to device connectivity for phones and sensors. The latency is higher than terrestrial 5G—around forty milliseconds—but for soil monitoring, that's fine. Luna: Honestly, if today's conversation gave you something useful, you know the drill. If it was worth a coffee to you, the link is buy me a coffee dot com slash fexingo. No pressure, just if it helps. Lucas: Yeah, that's the spirit. And we appreciate everyone who's already done that—it keeps this show ad-free and focused on the actual tech. Luna: So back to the soil. Are there any real-world examples of a farm that's fully transitioned to 5G? Lucas: There's a case study out of Iowa—a soybean farm called 'Hickory Ridge' that partnered with John Deere and a local carrier. They deployed twenty sensors per acre across two thousand acres, all connected via a single 5G tower and a Starlink backup. In the first season, they reduced fertilizer use by eighteen percent while maintaining yield. That's a direct cost saving of about forty dollars per acre. Luna: Forty bucks an acre on two thousand acres—that's eighty thousand dollars. Enough to pay for the equipment in one season. Lucas: Exactly. And that's just fertilizer. They also saw a twelve percent reduction in water use and a five percent increase in yield from better planting timing. The farm manager said the biggest surprise wasn't the savings—it was the ability to predict disease outbreaks. The sensors detected a moisture pattern that historically leads to mold, and they applied fungicide only where needed, instead of blanket-spraying. Luna: That's the dream, right? Targeted intervention instead of brute force. Lucas: That's the promise of 5G in agriculture. It enables a shift from reactive to predictive management. And the data is getting richer. Some sensors now measure leaf wetness, solar radiation, even wind speed at canopy level. All that streams over the same 5G network. Luna: What about livestock? I've heard about connected cow collars. Lucas: That's real. Companies like CowManager and HerdDogg make ear tags and collars that monitor temperature, rumination, and location. On a 5G network, you can track a herd in real time and get alerts if a cow's temperature spikes—indicating illness—hours before symptoms appear. One dairy farm in Wisconsin reduced mortality by fifteen percent using that system. Luna: So this isn't just crops. It's the whole food system. Lucas: Right. And the network effects compound. As more farms adopt 5G, the carriers have more incentive to improve rural coverage, which brings broadband to underserved communities. The FCC's Rural Digital Opportunity Fund has allocated billions for exactly this, and 5G is a key part of those plans. Luna: But there's a risk of a digital divide within agriculture. The bigger farms get the tech and the savings, while smaller farms fall behind. Lucas: That's a real concern. The USDA is piloting a program that subsidizes 5G connectivity for farms under five hundred acres. And some land-grant universities are building open-source platforms that let small farmers plug into the network without paying proprietary software fees. The idea is to democratize the data layer. Luna: That's promising. So where do you see this going in the next three to five years? Lucas: I think we're going to see the 5G farm become the default for any operation above a certain scale. The technology is already cost-effective. What's lagging is the regulatory and interoperability piece—making sure a Deere tractor can talk to a Case IH tractor on the same network, and that the data formats are standardized. There's a consortium called AgGateway working on that. Luna: So it's not just about the signal. It's about the software stack. Lucas: Exactly. The 5G radio is the pipe. The value is in the applications that run through it. And we're only at the beginning of building those. Luna: Great conversation. Thanks Lucas. Lucas: Thanks Luna. See you next time.
