Navigating Connectivity: Cellular Data Versus LoRa in Precision Agriculture

IoT powered Precision Agriculture can be complex, especially when it comes to network infrastructure, and choosing a network solution can be one of the most consequential choices one can make. According to Grandview Research, the precision agriculture market is poised to reach $43 billion by 2025, emphasizing the industry’s growth potential. However, when deciding to adopt a network for IoT, the choice between utilizing cellular data and LoRa technology is not always clear cut, as each presents distinct advantages and disadvantages, which will be explored in this article.

POWER CONSUMPTION

Energy efficiency is one of primary considerations when implementing IoT in agriculture. LoRaWAN, the open standard protocol utilizing LoRa radio technology, adopts a reliable and simple method of defining three classes of devices to minimize protocol complexity and energy consumption. This approach ensures that devices in the field operate with optimal power efficiency. The significance of low power consumption becomes apparent when considering the remote and often off-grid locations of agricultural operations. LoRa’s ability to operate on minimal energy resources positions it as a sustainable and practical choice for many applications. Cellular devices can also operate with relatively low power consumption, but nearly always consume more power to operate than LoRa.

RANGE AND CONNECTIVITY

LoRa and Cellular can provide a long-range signal, though using gateways with Ethernet backhaul, LoRa devices can often be deployed to areas where cellular coverage is scant or nonexistent. This makes LoRa an excellent choice for remote areas that may lack existing cellular coverage or power sources. However, the existing robust cellular data infrastructure in many rural areas in the United States and elsewhere mean that in many use cases, cellular devices can be deployed easily with less setup that a LoRa powered device. In regions where cellular coverage is already well established, utilizing this cellular infrastructure might provide a seamless and reliable solution.

DATA COST

While the cost of deploying and maintaining sensor networks is a concern, the expense associated with data plans over time can be a decisive factor in choosing between LoRa and Cellular Data. For instance, smaller and medium scale farms may find it economically challenging to afford cellular connections for many devices drawing data from sensors in a large field or group of fields. The incorporation of SIM cards with monthly bills per device could outweigh the potential yield advantage, often making Ethernet gateway LoRa a more cost-effective alternative, especially in dense sensor node deployments. This being said, there are still associated costs with LoRa, such as gateway hardware and maintenance costs, and the convenience of Cellular connectivity may outweigh any additional cost for some.

SUMMARY

Choosing between Cellular Data and LoRa technology is a strategic decision that hinges on the specific needs and conditions of each farming operation. The considerations of location, terrain, power consumption, and data cost underscore the importance of a tailored approach to connectivity solutions. As the industry continues to embrace technological advancements, networking technology will continue to evolve with it, and these various strengths and weaknesses will change as well.

Low Power, Wide Area Networking and its Advantages in Agriculture 

In the ever-evolving landscape of agriculture in 2024, the integration of Internet of Things (IoT) systems has become a key aspect of a successful operation. When deciding to implement IoT systems into an agricultural project, it is important to consider which networking solution is right for the application. Among the array of options, Low Power, Wide Area Networking (LPWAN) emerges as a frontrunner, offering many advantages that cater specifically to the agricultural space’s diverse needs. 

Longer Range for Rural Environments: 

One standout feature of LPWAN is its impressive range, making it an ideal choice for the expansive and often remote landscapes of gorw sites. With a effective range often spanning from 2 km to up to 20 km, LPWAN excels in providing connectivity even in a long distance environment. This extended reach ensures that agricultural operations covering vast areas can stay connected, facilitating efficient data transmission across fields large and small. 

Enhanced Connectivity in Challenging Terrain: 

IoT for agriculture often needs to be deployed in a diverse range of terrain, from dense forests to vast open fields. LPWAN’s ability to penetrate through obstacles and navigate irregular topographies makes it well-suited for such environments. This adaptability ensures that critical data can be transmitted reliably, even in the face of geographical features that would interfere with other methods of networking, providing farmers with a reliable real-time understanding of their land, often in areas that other technology cannot be effusively deployed. 

Low Power Consumption: 

When operational efficiency is paramount, as is the case with managing labor and natural resources, the low power consumption of LPWAN stands out as a key advantage. Unlike traditional networking solutions that may require frequent battery replacements or significant dedicated energy sources, LPWAN devices boast prolonged battery life, only turning on when transmitting, and only for exactly as long as needed. This directly translates to reduced maintenance efforts and costs, allowing farmers to focus on optimizing their processes without the constant concern of powering or replacing devices. 

Cost-Effectiveness: 

Implementing IoT solutions in agriculture can be a significant investment. LPWAN, with its cost-effective open-source infrastructure, presents an attractive option for farmers looking to enhance their operations without breaking the bank. The extended range of LPWAN also means fewer base stations are required to cover large areas, further contributing to the overall cost efficiency of adopting this technology. 

Diverse Applications: 

The adaptability of LPWAN technology is one of its primary strengths, enabling a range of applications in agriculture. From soil monitoring and crop management to depth sensing and smart irrigation systems, LPWAN provides a versatile platform for implementing a huge set of use cases from a single device. This versatility empowers farmers to tailor their use of LPWAN according to their specific needs, fostering innovation and efficiency across various aspects of agriculture and telemetry. 

As the agricultural industry continues to embrace the era of IoT, Low Power, Wide Area Networking emerges as a compelling choice, offering an extended range, adaptability to challenging terrains, low power consumption, cost-effectiveness, and a versatile platform for diverse applications. In a world where precision and real-time data are paramount, LPWAN stands as a testament to the potential synergy between technology and agriculture, helping usher in a new era of smart and connected farming.

Solutions in Precision Agriculture

As climate conditions continue to shift while the global population increases, farmers and food producers everywhere need to continually adapt their methods like never before. Managing and allocating resources to maximize efficiency is crucial, and precise data-driven monitoring is key to accomplishing this. Understanding and overcoming the challenges of farming in the 21st century introduces us to the world of precision agriculture.
What is precision agriculture?
Though definitions can vary, the International Society of Precision Agriculture defines it as “a management strategy that takes account of temporal and spatial variability to improve the sustainability of agricultural production.”
In practice, this generally boils down to a system of agriculture that aims to maximize efficiency in food production while minimizing waste and maintaining a healthy (and ideally self-sustaining) ecosystem. Some experts suggest that precision agriculture draws its roots from the adoption of mechanized processes of food cultivation in the early 20th century, continuing through the Green Revolutions of the 1960’s, when new techniques of controlled irrigation became standard and newly developed high-yield strains of crucial grains were introduced in the form of dwarf wheat and hybrid rice. Today, precision agriculture is driven by technological innovation and careful analysis of continuously changing data in real time.
The use of advanced metrics for managing agricultural production is not just a cost-saving measure used by food producers; it is instead vital to keep up with the ever-increasing demand for nutritious food globally. One frequently cited statistic estimates that “world food production needs to increase by 70% to feed the world population in 2050”, and to produce this food, “it is estimated that 52.8 million gallons of water per second are required”.
Feeding the World’s Present and Future Generations
Raising the world’s net food production is no easy feat, especially when considering delicate environmental considerations. It is now abundantly clear that previous techniques used to maximize food production, like monocropping and concerted animal feeding operations (or CAFOS), are not sustainable in the long term.
This is where the role sensors play in precision agriculture systems come into play. One of the most important and commonly used sensors in agriculture is the soil moisture probe. Soil moisture is a critical factor influencing plant growth, nutrient uptake, and overall crop health, and maintaining the right soil moisture levels is essential for ensuring optimal conditions for plant development. Soil moisture probes can enable farmers to tailor irrigation schedules to the specific needs of each crop and can adjust accordingly. These probes use capacitance or impedance to provide accurate and real-time data about soil moisture levels. To further monitor and manage irrigation systems , pressure sensors are strategically placed within irrigation systems to measure water pressure. This data is then analyzed to determine if adjustments are needed to maintain an optimal water flow rate for different crops.
Of course, natural irrigation must be tracked and accounted for as well. Understanding local precipitation patterns empowers farmers to adapt and optimize their farming practices by gaining insights into rainfall patterns. Rain buckets, also known as rain gauges, operate on a simple yet effective mechanism, consisting of a funnel that directs rainwater to a calibrated container, which is then measured to determine the rainfall intensity. The next level of hydration tracking lies directly at the plant level.
Monitoring leaf wetness is crucial for preventing diseases, as excessive moisture on plant surfaces creates favorable conditions for pathogens to thrive. Early detection and management of these conditions are essential for crop protection. Leaf wetness sensors use conductive or capacitive methods to detect moisture on plant surfaces. These sensors provide real-time information about the duration and intensity of leaf wetness, helping farmers make informed decisions on irrigation and disease control.
All the sensors listed above are just pieces of the overall puzzle of developing and maintaining a precision agriculture operation. Every crop and plot of land may require or benefit from their own specialized monitoring systems, but each of these sensors and the resulting adaptations from the data make up the present and future of precision agriculture, with only new innovations and techniques to come.
