What is IoT asset tracking?

IoT asset tracking is the application of IoT technology to asset management. It connects tagged items in your inventory - transportation, people, shipments and such - to your asset management ecosystem and gives real-time insights into where each item is in the world, how far along it is in your supply chain, and how long it takes each item to move through it.

Many industries can minimise human errors, losses and theft by replacing manual asset management with real-time location systems (RTLS) tracking. Gaining real-time insights and data into what is happening to the asset can improve logistics, resource management and security.

This guide will cover everything your organisation needs to know about IoT asset tracking. We’ll go through the basics, the different types of asset tracking solutions available to you, the benefits effective asset tracking can reap, and various use cases for real-time IoT asset tracking.

Types of IoT asset tracking solutions

One of the first things you’ll want to decide on when investing in IoT asset tracking is the type of tracking technology to rely on. RTLS solutions have a broad range of use cases and depending on what your business needs. Here are examples of the most popular tracking solutions:

Long and wide range asset tracking

GPS Asset Tracking

The Global Positioning System (GPS) is a satellite-based navigation system developed by the US Government. It uses global satellites to triangulate the location of an asset by sending and receiving several signal types to a set of 4 satellites in position. It is part of the GNSS and one of the GNSS most accurate systems.

GPS trackers are the most widely used type of trackers, which makes them a ready-available low-cost option. They are also a suitable low-power option. Current system accuracy is within 3m or 95%.

The system is ideal for tracking assets that travel around the world on long routes and through remote locations.

 

GNSS / Satellite

Satellite tracking utilises the Global Navigation Satellite System (GNSS) that encompasses a number of international navigations systems, among which GPS, GLONASS, Galileo and BDS.

GNSS tracking determines the position of an asset by measuring the time it takes the signal to reach from orbit. Sending and receiving signals from the orbital satellite also means the strength of the signal is influenced by obstacles, so this type of tracking is not suitable for indoors and underground.

GNSS trackers are compatible with all navigation systems within the network, which makes them a good option for global-scale operations that require more frequent updates.

 

How satellite asset tracking works

Cellular

Tracking assets with cellular connectivity relies on getting location data from nearby cell towers. Each tower location is mapped within a global database and when passing in the proximity of one, the tracker sends an update that is currently in its vicinity.

Cellular tracking is currently the most popular solution for IoT, because it supports highly accurate location tracking with real-time and high-volume data capabilities.

This solution type is suitable for highly mobile assets, such as road vehicles and cargo, where location stamps and asset status data is needed at regular intervals.

With the advancement of 5G, cellular tracking accuracy is expected to increase even further.

 

LPWAN

Low Power Wide Area Networks are a subset of cellular connectivity that has been developed specifically for the IoT industry. It includes networking options like NB-IoT and LTE-M.

LPWAN solutions exist to make cellular connectivity more affordable, secure and less power-intensive by transmitting data with a shorter, weaker signal. While the hardware for LPWAN is similar in price to cellular, it can cut down on networking costs.

LPWAN solutions create an internal network subset, hence the increased security and are perfect for tracking assets within the designated area. Examples may include shipping docks, construction sites, farms and such, where the assets are expected to remain on-premise.

 

How cellular tracking works

 

Short-range asset tracking

Ultra-wideband

Ultra-wideband has grown in popularity in recent years thanks to its high level of accuracy. It can detect assets with centimetres and remains accurate in the face of interference.

UWB uses precision tracking anchors to define an operational space and uses radio signals to track tagged assets within it. Because it uses a wide bandwidth, it does not interfere with other transmissions, making it ideal for indoor use cases.

Tracking with UWB is based on several methods. Your tracker can calculate positioning based on the signal send and arrive times or the angle of arrival.

UWB is a popular choice for warehouse logistics, entertainment, sports and any other case that requires high precision tracking.

Wi-Fi

Wi-Fi is unique among the IoT asset tracking options thanks to its ability to transmit large quantities of data in a short amount of time. It’s fast and reliable, making it ideal for short-range data transmission.

On the other hand, Wi-Fi is less than ideal when it comes to accuracy. It relies on triangulation and is only accurate within 15m. It’s expensive as well, especially when supporting more than ten to twenty devices.

Wi-Fi uses RSSI technology, much like Bluetooth to track assets via the signal strength, and can leverage the angle of arrival in some cases.

 

Bluetooth

Tracking via Bluetooth is based on measuring the signal strength of the Bluetooth receiver compared to the Bluetooth beacons within range. This is the so-called received signal strength indicator or RSSI value.

With the advancement of Bluetooth 5.1. the technology has incorporated tracking via angle of arrival (AoA) and can produce real-time meter accuracy and direction-finding.

Much like UWB, Bluetooth tracking solutions are often used for indoor logistics, where you can set up the beacons and define the tracking space for best results.

Bluetooth asset tracking

 

RFID tagging

The last type of IoT asset tracking to consider is RFID tagging. RFID is a passive form of asset tracking because it cannot pinpoint a device’s location. Instead, it just reports whether or not a particular RFID tag is within range of an RFID scanner.

For instance, you could have a handheld RFID scanner that only detects tags within a few centimetres of the scanner. Or you could have a scanner with up to 800m of range that alerts you whenever a tag enters that range.

Although RFID can’t provide precise location information or transmit data, it is available in various form factors and ranges. It doesn’t require a battery and is very low cost. RFID is highly susceptible to interference, though, which is important to keep in mind.

How IoT asset tracking works

Tags

In order to track an asset, it has to be visible for the asset tracking system. This could be done through the so-called ‘tag’ which transmits signals. Both short and long-range navigation systems require your asset to be able to send and receive on specific bandwidths. The tags can come in many forms and be built in or attached to the asset.

Connectivity infrastructure

The connectivity infrastructure is the way to connect the tags to a system and locate them. GPS asset tracking, for example, would include a set of orbital satellites to which your asset would send signals. Cellular navigation would require cell towers and indoor tracking would rely on connecting via beacons and anchors. Your infrastructure would need to send the location data back to a database.

Management software

Asset location information needs to be sent to the business management software. The software identifies each of your tags and reads the data transmitted by your connectivity solution. You can use this system to view the location of your inventory in real-time.

JT IoT can also offer you the possibility to track and manage your cellular tracking IoT SIM tags via the Nomad Connectivity Management Platform. Integrate it with your existing software for a complete overview of your asset locations and data usage. 

The benefits of IoT asset tracking

Track your assets in real-time

The core benefit of IoT asset tracking is that it provides real-time insights into the location of your inventory items. IoT asset tracking lets you offer more precise shipment tracking to customers and build more advanced insights into your logistics timeline.

Depending on your operation, real-time asset tracking can be fully automated. Automated monitoring not only provides real-time location insights, but it can do so instantly at all hours.

Prevent theft and losses

IoT technology makes it much easier to reduce theft and loss as well. You immediately know when an item is moved without authorisation, reducing the time between loss and discovery of a loss.

Additionally, it’s easier to find items because they have built-in tracking. So whether an item was stolen or lost within your system, you can recover it faster and more reliably.

Save time and reduce disruptions

There are several ways you can use IoT asset tracking to save time and reduce disruptions in your logistics.

It’s more accurate and automatic than manual methods, reducing errors and hangups.

You can use the real-time data you collect through IoT tracking to find slow points and issues in your supply chain, highlighting potential solutions.

Finally, because IoT asset tracking is automatic, you can save person-hours for every item moving through your inventory.

Boost sustainability efforts

One significant long-term benefit of investing in IoT asset tracking is its potential to boost your sustainability efforts.

For most businesses, their supply chain accounts for 90% of their environmental impact. Making this impact positive is essential to promoting sustainability, winning over customers, and adhering to regional requirements.

To reduce this footprint, though, you need data. IoT asset tracking can provide you with this data, empowering you to strive towards carbon neutrality.

Industry use cases and applications

IoT asset tracking can be helpful in many different industries, including:
