Boosting Productivity with Scalable Indoor Tracking Solutions

Opening Notes

In a world where operational efficiency is crucial, indoor asset tracking in real-time is no longer a luxury but a necessity. Businesses across industries, whether in healthcare, logistics, retail, or manufacturing, are recognizing the importance of indoor positioning systems. It's not just about knowing where your assets are, but ensuring they are available when needed, optimizing their use, and minimizing costly inefficiencies.

Indoor positioning systems help companies gain real-time visibility of their assets, whether it’s equipment, inventory, or machinery. The IoT modules should be designed to offer seamless, scalable, and efficient tracking solutions, enabling businesses to automate asset management and reduce human errors.

What is RTLS?

Real-Time Location System (RTLS) is a technology that automatically tracks and identifies the location of people and objects in real time within a specific area. Using a network of sensors and tags that wirelessly communicate with a central gateway, RTLS provides live, accurate data about the movement and position of assets like tools, machinery, and even people. Unlike traditional inventory systems, RTLS gives businesses the ability to track assets in real-time, significantly reducing the risk of misplaced items. This capability is especially critical in industries where delays caused by lost assets can lead to costly disruptions and financial losses.

How Does an Indoor Positioning System Work?

An Indoor (IPS) uses Real-Time Location System (RTLS) technology to track assets. Each asset is fitted with a wireless tag that continuously sends signals to fixed anchors (or readers) placed around the indoor space. The system uses factors like signal strength and the time it takes for the signal to reach an anchor to determine the asset's location.

This data is processed and displayed on a centralized dashboard through IoT software, allowing users to track assets in real-time. With this continuous flow of data, operations teams gain better control, visibility, and automation.

Key Technologies for Indoor Asset Tracking

Keeping track of assets indoors can be tricky, especially in busy warehouses, hospitals, or large facilities. That’s where modern indoor asset tracking technologies come in, using Bluetooth, RFID, Ultra-Wideband, GNSS, and Wi-Fi, making it possible to pinpoint the exact location and movement of every asset in real-time. Each technology has its strengths, helping businesses stay efficient, reduce losses, and maintain visibility across even the most complex spaces.

Bluetooth and Bluetooth Low Energy (BLE )

Bluetooth and BLE are commonly used for indoor GPS tracking, particularly within buildings where RFID or GPS may not be effective.

• BLE Beacons:

  Small, battery-powered devices emit Bluetooth signals containing unique identifiers. These beacons are strategically placed throughout the indoor environment to communicate with BLE-enabled tags worn by workers or attached to assets.

• Signal Strength (RSSI):

  BLE uses Received Signal Strength Indication (RSSI) to estimate the proximity between the BLE tag and the beacon. By analyzing RSSI values, the system can estimate the distance between the tag and the beacon, providing location data.

• Proximity Detection:

  Multiple BLE beacons work together to track the movement of assets or personnel within a defined area, providing near real-time data on location.

RFID (Radio Frequency Identification)

RFID technology is widely used in asset tracking, especially for people and equipment management in manufacturing environments. Here’s how it works:

• Tagging:

  An RFID tag, often attached to a worker’s ID badge or an asset, is used to track its location within the facility.

• Signal Transmission:

  RFID readers, placed at strategic points throughout the facility, emit radio waves. When an RFID tag comes within the range of a reader, the tag’s chip is activated, transmitting its unique identifier to the reader.

• Real-Time Tracking:

  The reader sends this information to a central system, enabling live tracking of the worker or asset’s movement.

RFIDs’ primary advantage is their accuracy and ability to work in harsh environments. It has a long read range and is resistant to interference. However, the tag must be within the reader's line of sight, and metal objects in the environment can disrupt signal transmission. Despite these challenges, RFID remains a reliable and robust technology for tracking people, assets, and equipment in real-time within an industrial setting.

Ultra-Wideband (UWB)

Ultra-Wideband (UWB) offers centimeter-level accuracy by measuring the time of flight of radio signals between the tag and receiver. It provides precise location data, making it ideal for environments that require high accuracy.

• High Precision:

  UWB technology excels in high-density environments like healthcare or manufacturing settings, where assets need to be tracked with pinpoint accuracy.

• Real-Time Location:

  UWB’s time-of-flight mechanism ensures near-instantaneous updates, enabling real-time tracking with centimeter precision.

While UWB offers superior accuracy, it requires specialized hardware for both the tags and readers, which makes it a bit more costly compared to BLE or RFID. However, its use in mission-critical applications is well justified by its high level of precision.

Global Navigation Satellite System (GNSS)

GNSS is primarily used for outdoor asset tracking, but can be integrated into hybrid systems for indoor tracking as well.

• Outdoor Use:

  GNSS is most effective for tracking in outdoor environments, where satellite signals are not obstructed.

• Indoor Hybrid Systems:

  When paired with BLE or UWB, GNSS can improve accuracy in large indoor environments like warehouses and distribution centers. By using GNSS for broader location tracking and integrating it with other technologies like BLE or UWB, businesses can ensure seamless, real-time tracking of assets both indoors and outdoors.

Wi-Fi

Wi-Fi is a widely adopted technology for indoor asset tracking, leveraging existing infrastructure to track assets in real-time. By using Wi-Fi access points, asset location is determined based on signal strength (RSSI) received from nearby access points.

Benefits:

• Cost-Effective:

  Utilizes existing Wi-Fi networks, minimizing infrastructure costs.

• Scalable:

  Easily expands to support large facilities or multiple sites.

• Real-Time Data:

  Provides continuous location updates for asset visibility.

• Integration:

  Can be combined with BLE or RFID for enhanced accuracy.

Wi-Fi offers a straightforward and efficient solution for businesses looking to optimize asset tracking without investing in new systems.

Wi-Fi Scanning: An Essential Technology for Indoor Asset Tracking

Wi-Fi scanning utilizes the existing Wi-Fi infrastructure in a facility to track the position of assets, personnel, or equipment within the indoor environment. Unlike traditional methods, such as RFID or GPS, which can be limited by environmental factors like walls or lack of coverage, Wi-Fi scanning leverages the abundance of Wi-Fi access points already present in most commercial buildings.

The Cavli C16QS and C17QS modules come with built-in Wi-Fi scanning capabilities. These modules continuously scan for nearby Wi-Fi networks and measure the signal strength of each access point. By triangulating these signals, the modules can estimate the position of the tagged asset or personnel in real time, providing highly accurate indoor tracking.
