LoRa™-based wearable technology for tracking cattle helps improve animal welfare and productivity on feedlots

Camarillo, California - March 31, 2016 -

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced that after extensive testing its Internet of Things (IoT) LoRa™ wireless RF technology has been selected by Quantified Ag to help improve the welfare and productivity of feedlot cattle through the ingenious use of a connected health tracker that attaches as an ear tag on the cattle. The tracker was designed, implemented and tested by Communication Systems Solutions (CSS), a design house and systems integrator specializing in long range communication technologies.

The tracker is part of a complete health monitoring system for livestock in which sensors in each ear tag constantly monitor livestock temperature, movement and other vital signs. The information from the ear tracker is relayed to a receiver, which sends data to a central system in the cloud where it is processed. Then, the information is sent back to the feedlot or ranch for viewing on a dashboard that is accessible via smartphones, tablets, email, SMS or secure website.

According to Quantified Ag CEO Vishal Singh, the method currently used to identify sick cattle is visual observation. For example, if a worker finds a sick animal, it is pulled from its pen and checked. The problem with this approach is that many animals typically do not openly display their symptoms so humans are not able to notice them until they are very ill.

“With our new LoRa-based health monitoring system for livestock, we are able to remove that human observational element so that animals cannot hide their symptoms anymore," said Singh. "The sensors in the tags provide feedlot operators the information they need to identify and treat sick animals sooner, which means the operators are less likely to lose livestock to illness and more likely to see them reach their desired weight. All of this adds up to healthier animals and increased productivity for feedlot operations.”

Another consideration in developing the monitoring system was range, scalability and battery life. According to CSS, which helped conduct the testing of Quantified Ag’s system, the LoRa-based solution provides the range and reduced interference needed to track thousands of animals with one gateway, making the system easy to install and cost effective. It also provides a long battery life to ensure the ear trackers last for the duration the animals reside at the feedlot.

“We are planning to target the leading feedlots in the U.S. with our LoRa-based solution,” said Singh. “The largest feedlot operator can have a capacity of up to one million heads, so you need a system that can quickly scale to that level while also providing a reliable signal and long battery life.”

“Agriculture applications such as cattle monitoring are an ideal fit for LoRa and LoRaWAN,” said Hardy Schmidbauer, Director of Wireless Products for Semtech’s Wireless and Sensing Product Group. “The Qualified Ag solution is a great example of how sensor monitoring solutions in agriculture can significantly improve productivity and return on investment.”
