A More Practical Way to Keep Track of Cattle on Large Pastures
Managing cattle across a large pasture is very different from managing animals inside a small, fenced farm. A rancher may know how many cattle entered a grazing area in the morning, but confirming their location later in the day can require hours of driving, walking and checking difficult terrain.
Most cattle remain with the herd, but individual animals can become separated. A damaged fence, an open gate, illness, extreme weather or the search for water may cause an animal to move into an unexpected area. By the time the rancher notices that one is missing, its last known location may already be several kilometres away.
This is where a LoRaWAN GPS cattle tracker becomes useful. It does not replace the farmer’s experience or the need to inspect the animals. Instead, it provides another layer of information that makes daily herd management more focused and efficient.
From searching for cattle to checking their location
A GPS collar periodically calculates the animal’s position and sends the coordinates to a LoRaWAN gateway. The gateway forwards the information to a server, where the rancher can view it on a computer or mobile application.
This creates a straightforward working process:
Each collar is assigned to a specific animal.
The device collects a location according to its configured schedule.
Position and battery information are sent through LoRaWAN.
The management platform displays the animal on a map.
The system generates an alert when an unusual event occurs.
The displayed point may not represent the animal’s exact position at the current second. It normally shows the latest successful location report. For ordinary herd supervision, this is often more useful than continuous tracking because it reduces energy consumption and extends battery life.
If an animal leaves an assigned area, the reporting frequency can be increased temporarily. Once it returns to normal conditions, the collar can resume its energy-saving schedule.
Why LoRaWAN is suitable for remote farms
Cellular GPS trackers work well where mobile coverage is stable, but every tracker normally needs network access and a SIM subscription. This can become expensive when a farm manages hundreds or thousands of animals.
LoRaWAN uses a different structure. The cattle collars communicate with one or more gateways installed around the farm. The gateway, rather than every collar, provides the connection to the internet.
This arrangement can offer several practical advantages:
No SIM card is required in each LoRaWAN collar.
The devices can remain in a low-power state for most of the day.
A private network can be deployed where mobile coverage is weak.
One infrastructure system can support a large number of animals.
The farm can control the gateway locations and network coverage.
LoRaWAN is a long-range technology, but its real performance depends on the environment. Hills, forests, buildings and low antenna positions can all reduce coverage. A gateway placed on an elevated structure will usually perform better than one installed close to the ground.
For a large ranch, it is sensible to test the radio signal at water points, pasture boundaries, valleys, shelters and other places frequently visited by the herd. Additional gateways can then be installed in areas where the first gateway cannot provide reliable coverage.
Virtual boundaries that follow the grazing plan
Pasture boundaries do not always remain the same throughout the year. A ranch may divide land for rotational grazing, temporarily close an area or move cattle according to water and forage conditions.
The platform allows the farm manager to create virtual boundaries on a map. Different groups can be assigned to different grazing areas without changing the configuration of every collar manually.
When a tracked animal crosses a boundary, the platform records the time and location and sends a warning to the responsible person. A useful system can distinguish between several situations:
An animal is approaching the edge of the pasture.
An animal has crossed the permitted boundary.
A collar has remained outside the area for a defined period.
One animal is moving away from the main herd.
Several animals are leaving through the same location.
The last situation can be especially important because it may indicate an open gate or a damaged section of fencing rather than normal individual movement.
GPS geofencing should not be treated as a physical barrier. Positioning has a natural margin of error, so virtual boundaries require a safety buffer. Roads, cliffs, deep water and other hazardous locations should still be protected with appropriate physical fencing.
Looking beyond a single location point
The value of a cattle tracker is not limited to finding a missing animal. Historical movement can show how cattle use the pasture over time.
If animals repeatedly gather in one section while avoiding another, the farmer can investigate water availability, forage quality, shade or ground conditions. If one animal moves much less than the rest of the herd, it may deserve closer inspection.
A motion sensor inside the collar can also help the device recognize general activity changes. It may support alerts for prolonged inactivity or unusual movement, but this information must be interpreted carefully. A low-activity alert is not a veterinary diagnosis. It is a reason to inspect the animal and assess the situation directly.
Good livestock software should present location, activity and device condition separately. This prevents a communication interruption from being mistaken for an animal health problem.
Battery life depends on the operating strategy
It is tempting to evaluate a cattle tracker only by the battery capacity stated in mAh. In practice, battery life is strongly influenced by the way the device is configured.
The most important factors include:
How often the GNSS receiver calculates a position
How long satellite acquisition takes
How frequently data are transmitted
LoRaWAN signal quality
Transmission power and retransmissions
Ambient temperature
Motion-sensor settings
Battery chemistry and ageing
A collar that reports every few minutes will consume much more energy than one reporting every hour. However, using the same long interval in every situation can delay an important alarm.
A better approach is adaptive operation. The device uses a longer interval under normal conditions and switches to more frequent positioning when it detects movement near a boundary or another abnormal event. This provides useful tracking without keeping the most energy-intensive components active all the time.
Solar charging can extend the operating period, but it should not be treated as unlimited power. Dust, mud, animal hair, winter weather and the changing orientation of the collar all affect the energy collected by a small panel.
A realistic ranch deployment
Consider a ranch divided into three grazing sections. Cattle rotate between these areas during the season, and some sections are partly hidden by hills.
Before installing trackers across the entire herd, the farm begins with a pilot group. An outdoor LoRaWAN gateway is installed at an elevated point, and test collars are carried through the main routes used by the cattle.
The test reveals that most of the pasture has reliable coverage, but a valley behind one hill receives inconsistent data. A second gateway is added to cover this area. The farm then creates a separate geofence for each grazing section and assigns the pilot animals to the active pasture.
During normal operation, the collars report at an energy-efficient interval. When an animal crosses a boundary, the platform changes its status and alerts the farm manager. The manager checks the latest coordinates and movement direction before sending a worker to the area.
After the pilot period, the farm reviews battery consumption, lost packets, collar retention and false alarms. Only then are the final settings applied to the remaining herd.
This staged approach is more dependable than selecting a range figure from a product specification and immediately deploying hundreds of devices.
Technology that supports the people on the farm
A livestock tracking system is most valuable when it fits into ordinary farm work. It should make it easy to see which animals are safe, which devices need maintenance and which events require attention.
The objective is not to replace ranch workers with dots on a map. It is to give them better information before they travel into the field.
A well-planned LoRaWAN cattle tracking solution can reduce unnecessary searching, provide earlier notice of boundary crossings and create a clearer record of how the herd uses the land. Its success depends on suitable hardware, thoughtful reporting intervals, reliable gateway coverage and, most importantly, a deployment designed around the actual pasture.
