In the rapidly evolving landscape of supply chain management, businesses are constantly seeking innovative ways to streamline their operations, reduce costs, and deliver exceptional customer experiences. One powerful solution that has gained significant traction in this domain is the use of sensor networks and IoT (Internet of Things) technologies. Among the various options available, LoRaWAN (Long Range Wide Area Network) has emerged as a preferred choice for asset tracking and supply chain visibility.
The Rise of LoRaWAN for Asset Tracking
LoRaWAN offers a compelling set of benefits that make it an increasingly popular choice for supply chain applications. Compared to alternatives like cellular networks, RFID (Radio Frequency Identification), Wi-Fi, and Bluetooth (BLE), LoRaWAN stands out for its lower deployment and maintenance costs, an ever-growing ecosystem of standards-based tracking devices and environmental sensors, and rapidly expanding network coverage across land, sea, and indoor environments.
As highlighted in recent research, LoRaWAN is designed to support a massive number of devices simultaneously, making it an ideal solution for tracking and monitoring a wide range of assets, regardless of their quantity or location. The key components of a LoRaWAN asset tracking solution include the devices (trackers and environmental sensors), the network gateways, network management software, and the supply chain visibility application.
Versatile LoRaWAN Devices for Supply Chain Needs
LoRaWAN-powered devices, such as trackers and environmental sensors, are designed to be low-cost, long-range, and low-power, enabling extended battery life over long periods and eliminating the need for frequent battery replacements or recharging. These devices can be tailored to support a variety of supply chain use cases:
- LoRaWAN-GPS trackers are used to manage high-value outdoor assets, tracking their location and movement.
- LoRaWAN-BLE (Bluetooth Low Energy) devices are employed for indoor tracking, leveraging proximity-based technologies.
- LoRaWAN-based location estimation solutions provide an alternative for applications that do not require precise coordinates but still benefit from tracking data combined with other environmental information.
Flexible LoRaWAN Network Architectures
LoRaWAN networks can be public, private, or hybrid in nature, offering businesses the flexibility to choose the most suitable approach for their supply chain needs. While public LoRaWAN networks are available across most major transportation routes, private LoRaWAN networks can be built and managed at a very low cost. Hybrid public-private networks are a common implementation for asset tracking, as they deliver a combination of outdoor and indoor connectivity to meet the diverse requirements of supply chain operations.
Furthermore, the integration of terrestrial and satellite LoRaWAN networks provides far-reaching and cost-effective connectivity for a wide range of fixed, mobile, and nomadic use cases, ensuring seamless coverage and uninterrupted data transmission throughout the supply chain.
Enhancing Supply Chain Visibility and Decision-Making
The data collected by LoRaWAN sensors is consumed by end applications, providing increased supply chain visibility and management for users. These applications may include inventory management systems (IMS), warehouse management systems (WMS), order management systems (OMS), or enterprise resource planning (ERP) systems.
By capturing a wealth of location and state data throughout the supply chain, businesses can make informed decisions and act in real-time to improve their operations. Some of the key use cases for LoRaWAN-powered asset tracking include:
Inventory Management
LoRaWAN enables businesses to efficiently monitor and manage inventory levels, eliminating the risk of human error from manual processes. Sensors on pallets, in trucks, or in storage areas can automatically track inventory levels, monitor stock movements, and provide timely alerts of mishandling or discrepancies.
Cold Chain Monitoring
Temperature-sensitive goods, such as food or pharmaceuticals, require special care during transportation and storage. LoRaWAN devices are integral to diligently tracking and monitoring temperature, humidity, and other environmental conditions, ensuring that perishable items are kept within the required temperature range, minimizing spoilage, and guaranteeing product quality.
Returnable Asset Tracking
Returnable assets, like pallets, containers, kegs, or crates, play a crucial role in the supply chain. LoRaWAN tracking provides the data to effortlessly monitor the location and usage of these assets, optimizing asset utilization, reducing loss, and improving asset recovery processes.
Theft Prevention and Security
Protecting valuable assets is a top priority for supply chain professionals. LoRaWAN devices can be seamlessly integrated with security features like motion sensors or tamper detection mechanisms, particularly in warehouses. By creating a “smart building” scenario, businesses can keep a watchful eye on asset movement in real-time and receive immediate alerts in case of unauthorized access or theft attempts, bolstering security and safeguarding assets.
Embracing LoRaWAN for Efficient and Secure Supply Chains
Asset tracking and condition monitoring are critical to ensuring goods are transported, received, and delivered on time and in proper condition. By embracing LoRaWAN-powered solutions, businesses can reach new levels of efficiency, transparency, and security in their supply chain operations.
As more companies continue to look for ways to reduce costs while boosting efficiency, LoRaWAN technology offers a robust option that empowers supply chain professionals with the data they need to manage costs, streamline operations, and make informed decisions while delivering high-quality customer experiences.
