ZLOC-U UWB and IMU based ITNS (Accuracy: 20-50 cm)

Ultra Wide Band (UWB)

Unlike traditional radio technologies (like Bluetooth or Wi-Fi), UWB operates with the signal’s so-called Time of Flight rather than RSSI (Received Signal Strength Indication), which makes the technology much more precise and enables it to make very exact ranging measurements. This opens up new opportunities in several business verticals, that have simply not been possible before.
Ultra Wide Band (UWB) is a technology for the transmission of data using techniques which cause a spreading of the radio energy over a very wide frequency band, with a very low power spectral density. The low power spectral density limits the interference potential with conventional radio systems, and the high bandwidth can allow very high data throughput for communications devices, or high precision for location and imaging devices.

IEEE 802.15.4a standard

The 802.15.4a amendment added Ultra Wideband into the standard, which introduced new feature of very precise ranging gained by the UWB PHY.
UWB utilizes a train of impulses rather than a modulated sine wave to transmit information. This unique characteristic makes it perfect for precise ranging applications. Since the pulse occupies such a wide frequency band, its rising edge is very steep and this allows the receiver to very accurately measure the arrival time of the signal. Plus the pulses themselves are very narrow, typically no more than two nanoseconds.
Due to the nature of the signals, UWB pulses can be distinguished even in noisy environments, plus the signals are resistant to multipath effects. All of these traits give UWB big advantage over traditional narrowband signals in case of ranging capabilities. Also due to the strict spectral mask, the transmit power lies at the noise floor, which means that UWB does not interfere with other radio communication systems operating in the same frequency bands, since it just increases the overall noise floor, a principle that is very similar to spread spectrum technologies (CDMA).

Proximity Marketing

Proximity is about reaching a user or customer based on their actual physical relationship to other objects. For example, when they are on a bus or when they are approaching a particular coffee shop or when they are exiting your store. Technology means businesses can choose when to send which messages and to whom in order to achieve the best results and satisfy customers.
Proximity means knowing where your customers and assets are and interacting with them in ways that are meaningful. Without proximity technology, marketing efforts can fall flat by not addressing the customer at the right moment in their journey.

AADONA ZLOC-U solution

We help you by delivering highly reliable UWB indoor positioning system, which can be quickly demonstrated in customer premises and subsequently easily scaled into the large complex industrial environment. In order to guarantee best performance to your customer, our solution integrates complex UWB system management tools. Check positioning precision in real-time, record capture files for further analyses, change device configuration remotely or get system reports periodically. All these functions guarantee your success. To locate objects AADONA ITNS uses a set of hardware devices collecting UWB signals and transmitting them to the ITNS server, where the position is calculated by the location engine.
Set of devices and software tools used are as follows :
  • Wireless tags with UWB to be placed on the assets to be tracked
  • Hubs/Gateways connected with power and ethernet/WiFi which map the area and track the tags with accuracy
  • A server running software on premises/cloud for managing and setting up the network/li>
  • A warehouse/industry/factory 3D simulation environment with ability to place and name tags for various machines, devices and humans. This allows you to watch, zoom and track every resource on the floor in real time.
Wireless Tags in regular interval transmit very short UWB signal, which is received by the ambient hubs. The hubs send the timestamps from the UWB signals via Ethernet or WiFi infrastructure to the ITNS server running the management software, which calculate the exact position and store data in the database. Positioning data are then available through the API. ITNS software also allows to visualize the real-time tracking and to analyze the stored data. Key benefits choosing AADONA ITNS for your project is outstanding system management, easy scalability and high precision.
These set of devices can provide unprecedented level of accuracy in the tracking of assets in any industry vertical. With ultra low power consumption and robust network, it works in high speed environments with ease. With centimetre level accuracy, the user can set-up geofencing for resources and humans to generate alerts whenever a breach occurs. Access to various regions in the premises can be provided using the tags.
To decrease the latency in tracking, the server for monitoring and controlling the devices can be setup in the premises for swift notifications and actions.


  • Turns a factory/shop-floor/manufacturing unit/warehouse into an interactive map showing each asset and people’s locations in real-time.
  • Makes your space smarter by setting up geofencing on resources to allow you to get notified when a resource reaches a particular place.
  • Makes your space adaptive by learning the behaviour of each resource and the path it takes during its operation and suggesting potential faults and optimization of resources.


  1. Hub is a reference device with a known position. Set of hubs creates location infrastructure where tags are being located.
  2. The primary goal of the device is to gather radio signals from mobile locators called tags and forward them to our cloud IoT platform where the position is being estimated. Moreover, hubs can also receive data from sensors equipped within the tag such as acceleration, orientation, button event or custom data payload. Data are further exposed to the user via open API.

  3. Generally, the hub is an IP network device equipped with an Ethernet/Wi-Fi interface for both data backhaul and/or power supply. Hubs are configured and managed via our cloud IoT platform. They are delivered with holders to simplify the installation in any premises. They are usually mounted above tags which ensures maximum coverage and minimizes obstacles blocking its communication line.


  1. Tag is an active mobile locator. Its position is reported within selected refresh rate. Tracked objects need to be equipped with this device.
