IoT connectivity in agriculture is changing farming when our global food system needs it most. The UN projects our world population will reach 9.7 billion by 2050. This means agricultural production must grow 69% between 2010 and 2050. Our farms need smarter and quicker ways to grow food.
Farmers now use almost 100 million connected devices, with more being added each day. Agricultural IoT helps them watch soil conditions, monitor livestock health, control irrigation systems, and forecast crop yields. A farmer could feed 25 people sustainably 50 years ago. Now that same farmer can feed over 150 people. The real power of IoT goes beyond these numbers. It gives farmers the tools and information they need to boost production while using fewer resources.
Connected ecosystems let farmers make quick and smart decisions. To cite an instance, cattle wear IoT collars that send data about their location, temperature, and how they move. On top of that, it looks promising for the future. Researchers believe the global market for agriculture IoT solutions will be a big deal as it means that $33 billion by 2032.
This piece shows how IoT connectivity changes farming practices, tackles rural deployment challenges, and explores the tech behind smart agriculture. We’ll see how companies like Trafalgar Wireless provide reliable connections that keep smart farms running well, even in the most remote areas.
The Rise of Smart Agriculture
Traditional agriculture faces a turning point. Global challenges keep mounting, and farming methods that kept humanity fed for generations can’t keep up with today’s needs.
Why traditional farming methods are no longer enough
Farmers across the globe face challenges like never before. Weather patterns have become erratic and disrupt growing seasons that used to be reliable. This makes planning harder than ever. The financial picture looks bleak too. While input costs for seeds, fertilizers, and equipment upkeep keep rising, global market forces push agricultural commodity prices down.
The situation gets worse when you look at how inefficient conventional methods are. Traditional farming wastes about 60% of irrigation water and 30% of agricultural inputs, which hits profits hard. The food waste numbers paint an equally grim picture – we lose or waste one-third of all food produced globally each year.
Nature adds its own set of problems. Poor soil health reduces fertility and water retention. The loss of biodiversity makes farm ecosystems less resistant to pests and diseases. Young people leave rural areas to chase city dreams, and farms lose both workers and valuable knowledge.
What is the role of IoT in agriculture today?
IoT technology provides answers to these growing challenges. Agricultural IoT creates networks of connected sensors, actuators, and cloud platforms that let farmers track and automate crucial processes.
IoT systems gather data about soil conditions, weather, crop growth, and pest problems. Farmers use this information to:
- Use water, fertilizers and pesticides more efficiently
- Keep tabs on livestock health and behavior from anywhere
- Run greenhouses automatically
- Follow products from farm to table
The precision agriculture segment leads all IoT applications with a $7.83 billion market share in 2022. Smart sensors track moisture, soil quality, and temperature to give farmers immediate data. This helps them apply just the right amount of water or fertilizer exactly where crops need it.
Livestock benefit too. Sensors attached to animals track vital signs, movement, and location. Farmers spot diseases earlier, lose fewer animals, and manage their herds better.
How global food demand is driving innovation
The challenge looms large. The world population will hit 9 billion by 2050, which means food demand will double. Total Factor Productivity (TFP) growth – how efficiently we produce agricultural output – has dropped to its lowest rate in decades.
These challenges push technology forward fast. The global IoT in agriculture market reached $13.73 billion in 2023 and should grow to $22.65 billion by 2028, with a 10.7% compound annual growth rate (CAGR). Some experts predict even bigger growth – up to $84.50 billion by 2031 at a 12.6% CAGR.
Farmers now see the cost of falling behind on smart farming. Recent surveys show 58% of farmers believe new agricultural technology gives them an edge over competitors. About half would pay more for better-performing inputs.
Different regions and farm sizes show varied adoption rates. European and North American farmers lead the pack – 61% either use or plan to adopt at least one product within two years. Large farms over 5,000 acres show much higher adoption rates at 81% compared to just 36% for small farms under 2,000 acres.
Key Use Cases of IoT in Agriculture
IoT applications are turning modern farming from theory into practical tools that boost output and save resources. Let’s get into how these technologies help solve specific challenges in farms of all types.
Precision crop monitoring
Farmers now have an unmatched view of their crop health through field sensors and imaging technologies. These sensors gather detailed information about soil conditions, environmental factors, and plant growth. This helps them respond faster and more effectively. Remote sensing, spectral imaging, and robotics work together to collect information about plant traits, which guides decisions about fertilization, irrigation, and pest control.
Smart image processing can spot plants and fruits with high accuracy, even with changing light and busy backgrounds. Farmers can pinpoint exactly where they need water and fertilizer, and where they don’t. This precision helps cut waste while getting the best possible yields.
Livestock health tracking
Time limits and staff shortages make it hard to watch animal behavior through direct observation. Modern IoT-based systems do this work automatically. Small devices attached to animals track their vital signs, location, and how active they are.
The CowMonitor system shows this technology at work. It uses collar devices with motion sensors and wireless connections to track dairy cow behavior, especially during breeding times. These battery-powered units last up to 5 years and send data through Bluetooth to gateway devices that push information to cloud servers.
The results speak for themselves. Two German farmers used smaXtec and saw 80% fewer serious diseases and no animals lost to illness. Their milk production went up too. A US farmer boosted cow pregnancy rates from 25% to 33% with GEA CowScout.
Smart irrigation systems
Traditional irrigation wastes lots of water. Smart irrigation helps farmers use just the right amount of water at the perfect time. Weather data, soil moisture sensors, and smart controllers work together to make better watering decisions.
The numbers tell the story. Research shows soil moisture controllers saved 72% on irrigation in normal weather and 34% during droughts. Another study found 43% less water used in summer compared to manual scheduling, without hurting grass quality.
Autonomous machinery and robotics
Farm automation has grown from basic GPS tractors into advanced self-driving vehicles and specialized robots. These machines now handle planting, harvesting, weeding, and monitoring tasks.
Robotic fruit harvesters can spot and pick ripe produce with 98% accuracy while needing just one person to supervise. Carbon Robotics’ LaserWeeder uses AI and computer vision to find and eliminate weeds without chemicals.
These systems do more than save labor. They can work around the clock with incredible precision and collect valuable data as they operate.
Greenhouse automation
Smart greenhouses showcase some of agriculture’s most advanced IoT technology. These controlled spaces use sensors to watch and adjust temperature, humidity, light, air quality, and soil moisture automatically.
The results are impressive. Tomatoes grow twice as fast in IoT-enabled greenhouses compared to traditional ones. Smart climate control systems cut energy use by about 25% and water consumption by 33%.
A recent study of an IoT greenhouse system showed 32% less water used and 23% better crop yields on average. Some specialty crops did even better, with yields jumping up to 41%.
Connectivity Challenges in Rural Farming
Smart agriculture offers incredible benefits, but IoT technology deployment in rural farming areas faces major challenges. Rural connectivity creates big hurdles that need solutions before agriculture IoT can reach its full potential.
Limited infrastructure in remote areas
The gap between urban and rural America’s digital capabilities remains a serious concern. Right now, 80% of the 24 million Americans who don’t have fixed terrestrial broadband live in rural areas. This divide could grow as global download speeds are expected to jump from 39 Mbps in 2017 to 75 Mbps by 2022.
Rural farms deal with connectivity problems that urban businesses rarely face:
- Unstable internet connections that can’t handle live data transmission
- Physical obstacles like crops, canopies, and terrain that block signals
- Poor cellular coverage in less populated areas
- Unreliable power sources in remote spots
Money makes these problems worse. Telecom providers look at rural deployments the same way they do urban ones – they need business models where money coming in beats costs. Low population density and expensive installation costs make service providers think twice about investing heavily.
High latency and data loss risks
Quality and reliability issues often plague rural deployments, even where connectivity exists. Many agricultural IoT systems need live data transmission – something today’s rural infrastructure doesn’t deal very well with.
Latency – the delay between sending and receiving data – creates serious problems for time-sensitive farm operations. High latency means critical alerts about equipment failures, livestock health issues, or irrigation needs might arrive too late to prevent losses.
Satellite internet comes with its own set of problems, though many see it as an answer for remote areas. The FCC points out that satellite broadband “may not be fully sufficient for Next Generation Precision Agriculture technologies due to the unpredictability of service caused by high latency, capacity limitations, and costs for securing high volumes of data flows, especially when time-sensitive information is required”.
Rural environments’ transmission rates often drop because of delays. This leads to lost packets, network congestion, or data collisions – which end up forcing wasteful retransmissions that eat up network resources. Systems monitoring crop health, irrigation needs, or livestock welfare can fail catastrophically because of this unpredictability.
Device provisioning and maintenance issues
Setting up and maintaining IoT devices across large farm operations creates huge logistical challenges. Rural connectivity in big geographic areas needs complex solutions with multiple carriers and technologies.
One agricultural IoT provider found that “exploiting a single carrier in such a far-reaching deployment is often not practical, maybe even possible”. Managing multiple carrier contracts and connectivity plans internally becomes overwhelming quickly.
Weather and terrain affect network performance substantially. Signal strength varies widely between rural areas, urban environments, and other operational zones. These differences make consistent device setup and management a real challenge.
Edge computing might help solve connectivity problems. Local processing reduces the need for constant internet connectivity, unlike sending everything to the cloud. This approach helps agricultural IoT systems run efficiently even with spotty internet connections.
Other promising technologies include low-power wide area networks like LoRaWAN or NB-IoT. These let devices send data over long distances while using minimal power. New satellite technologies like Starlink also show promise in bringing high-speed internet to areas without traditional infrastructure.
Smart Agriculture IoT Connectivity Requirements
Smart agriculture’s success depends on connectivity that works 24/7 in tough environments. IoT in agriculture needs more than simple internet access, farmers need specialized connectivity solutions built for rural areas.
Reliable and continuous coverage
Data flow must be consistent when crops or livestock depend on it. Smart farming applications need uninterrupted connectivity across large areas, especially where regular networks struggle. This becomes even more crucial as sensor networks grow to track everything from soil conditions to equipment performance.
Regular cellular networks often can’t meet agricultural needs. This has led to hybrid connectivity approaches that use technologies like Low Power Wide Area Networks (LPWAN) for long-range, low-power data transmission in remote rural areas. Multi-network and multi-IMSI SIMs help solve these issues by connecting to the strongest available network automatically to avoid coverage gaps.
Low-latency data transmission
Speed in agriculture matters more than you might expect. Take wildfire detection systems, they need ultra-reliable low-latency communication (URLLC) with response times under 1 millisecond for quick detection and response. Livestock tracking systems also need real-time alerts when animals move beyond farm boundaries.
High latency can reduce operational efficiency and create risks in smart farming applications. Data transmission delays affect critical tasks like irrigation scheduling, pest detection, and livestock monitoring. Fifth Generation Mobile Technology (5G) offers a solution with its ultra-low latency for time-sensitive applications.
Edge computing offers another way to tackle latency issues. Processing data locally instead of sending it to the cloud reduces the need for constant internet connections and speeds up access to real-time data.
Scalability for large deployments
Agricultural IoT systems usually start small but expand quickly. Your connectivity solution must handle growing networks without losing performance. Key scalability factors include:
- Network capacity to handle thousands of connected devices simultaneously
- Infrastructure that supports increasing data volumes
- Flexible deployment options for varied agricultural environments
- Cost-effective expansion paths as operations grow
IoT technology adoption in agriculture keeps rising. IoT devices are expected to triple from 8.74 billion in 2020 to more than 25.4 billion by 2030. This rapid growth needs connectivity solutions that can scale without complete system overhauls.
Remote device management capabilities
Reaching IoT devices spread across hundreds or thousands of acres creates major challenges. Good remote device management lets you:
Monitor device health metrics across your network and get real-time alerts about potential issues. Schedule and run tasks to manage device groups with one-time or recurring actions. Update firmware and software over-the-air to add features without physical access.
Remote provisioning technologies like eSIM let you change carrier profiles without physical SIM swapping, a big advantage in agricultural deployments. As noted in one implementation, “Through the use of eSIM, agricultural IoT providers can provision devices to connect to the strongest available network to avoid gaps in coverage, and if the company chooses another carrier or connectivity technology, they can provision over-the-air to avoid physical SIM swapping”.
Secure out-of-band management capabilities add another layer of control. You can access devices even when primary networks fail. These systems can fix configuration changes automatically and keep network integrity intact without site visits.
Connectivity Technologies Powering Smart Farms
Modern farms depend on interconnected technologies to keep their smart systems running. Rural agricultural settings need specialized solutions that work in big areas where infrastructure is limited, unlike cities that have many network options.
Cellular networks (LTE, 5G)
Cellular technology serves as the foundation for many agricultural IoT systems. Standard LTE gives you the bandwidth you need for equipment tracking and video monitoring, though monthly costs can limit how many farm assets you can connect. Large corporate farms now build their own private 5G networks to support data-heavy applications like drone-based crop monitoring.
Simpler cellular categories play a vital role in agricultural IoT too. LTE-M and NB-IoT, made better by 3GPP Release 17, last longer on battery power and connect better in remote spots. These technologies use existing cellular infrastructure but with simpler communication protocols that use less power than standard LTE. NB-IoT and LTE-M subscriptions start at just $1.50 per device monthly, which costs much less than standard cellular rates.
Satellite and LPWAN options
Satellite connectivity becomes essential where cellular coverage doesn’t reach. Industry experts point out that farmers turn to satellite when sensors are too remote for cellular infrastructure. The market splits between low-throughput L-band services and broadband solutions from LEO operators.
Low Power Wide Area Networks (LPWAN) work great in agricultural settings because they:
- Send data over long distances while using minimal power
- Keep battery-powered devices running for up to 10 years
- Connect thousands of sensors across large areas
LoRaWAN leads the pack of unlicensed LPWAN options with a projected 36% market share by 2027. It works without cellular networks, making it perfect for remote setups when combined with satellite backhaul. Sigfox, Helium, and mioty offer similar options in unlicensed spectrum bands, providing economical connectivity for basic agricultural monitoring.
Private APNs and secure tunnels
Private Access Point Names (APNs) create dedicated gateways within mobile carrier systems and establish secure connections between IoT devices and enterprise systems. Private APNs let you customize network security settings, unlike public APNs that usually assign dynamic IP addresses controlled by mobile network operators.
These private networks add several layers of protection:
- They keep systems away from public internet exposure, which reduces attack risks
- You can set custom security policies for specific agricultural needs
- Your sensitive farm data stays within private networks
Your agricultural operation’s needs for data privacy, coverage, expandability, and control should guide your decision about private APNs. Basic monitoring might work fine with regular cellular security, but operations with sensitive data benefit from private APN’s extra protection.
Multi-network and multi-IMSI SIMs
Farm IoT systems that cover wide areas often need solutions with multiple carriers. Multi-network IoT SIMs from providers like Trafalgar Wireless keep connections going by switching to networks with the strongest signals.
These smart SIMs give you great flexibility through:
- Network switching that prevents coverage gaps
- Access to hundreds of operators worldwide
- Support for technologies from 2G through 5G and LTE-M
Connectivity specialist Transatel explains that “multi-network SIMs provide uninterrupted LTE/5G connectivity for smart farming systems, automatically connecting to a network with the best available signal”. This backup system helps farms deal with connectivity problems caused by terrain, weather, and distance.
The mix of cellular, satellite, LPWAN, private APNs, and multi-network SIMs creates a complete connectivity foundation for today’s smart farms. This technology powers everything from basic soil sensors to advanced autonomous equipment.
The Role of eSIM and Remote Provisioning
eSIM technology changes how agricultural connectivity works by getting rid of regular physical SIM card limitations. Farmers who use IoT networks in their large operations now have game-changing advantages with this digital approach to device connectivity.
What is eSIM and how it works in agriculture
eSIM (embedded SIM) is different from the plastic SIM cards we’re used to. These eSIMs use digital profiles that are built right into agricultural devices. The GSMA created the eUICC (embedded Universal Integrated Circuit Card) specifications back in 2016.
Agricultural devices like soil moisture sensors, weather stations, and livestock monitors use eSIM technology to connect through digital profiles instead of physical cards. The devices create secure connections after activation. They exchange credentials safely through the air using end-to-end security solutions.
The GSMA suggests that agricultural IoT SIMs or eSIMs should include an IoT SAFE applet. This helps create secure communication channels with each device. Farm data stays protected from unauthorized access with this security layer.
Benefits of remote provisioning for IoT devices
Remote SIM Provisioning (RSP) lets you manage SIM cards through the air without touching the devices. This creates several benefits for agriculture:
- Network flexibility – Devices connect to the strongest signal on their own, which helps in areas where coverage is spotty
- Carrier independence – You can switch network providers from anywhere without swapping physical SIMs
- Environmental resilience – eSIM hardware works better in harsh weather than physical cards that might get damaged
- Global deployment – Equipment works with different network providers across regions thanks to multi-carrier capability
In-Factory Profile Provisioning (IFPP) adds value by loading eSIM profiles during manufacturing. This means no manual setup is needed after production.
Reducing truck rolls and manual SIM swaps
The biggest advantage of eSIM in agriculture is not having to visit fields just to manage SIMs. Farmers save many hours by avoiding manual SIM swaps when they have hundreds of sensors spread across big fields. This leads to better operational efficiency.
eSIM makes things easier through bulk provisioning. You can order a thousand eSIM devices from a manufacturer and set them all up with one command. This is a big deal as it means that deployment time drops.
Many farmers start small with pilot projects in specific fields. They test things out before expanding to their whole operation. Later, they can grow their system without worrying about physical SIM limitations.

Farmers can now predict yields accurately, detect pests early, schedule irrigation better, and manage supply chains efficiently. These tools help farms produce food with minimal resources, which reduces water consumption and chemical use.
Edge computing on the farm
The farming industry benefits from edge computing that processes data right where it’s collected, eliminating constant cloud uploads. This technology’s adoption rate should reach 75% by 2025 across industries. Farmers find edge solutions work better and faster than cloud systems. These systems analyze soil moisture and temperature locally to provide quick insights without delays from connectivity issues.
Global standardization of IoT protocols
The agricultural technology sector needs common standards to work smoothly. Future standardization will help devices work together better, which makes data sharing easier throughout the farming ecosystem.
