Technologies
Ubudu supports most standard low power radio technologies BLE, UWB and LoRa to offer affordable solutions that best fit your requirements and environment.
Radio Technologies
Ubudu hybrid approach leveraging different radio technologies through the same system enables to adapt the solution to all use cases in different environments with the highest ROI.
Uses a very low energy level for short impulses, wide-bandwidth that are immune to multi-path and interference to bring high accuracy.
Is used to provide considerably reduced power consumption and cost while maintaining a similar communication range than classic Bluetooth.
Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet with very long range.
Radio standards
IEEE radio standards are used in all Ubudu products to ensure system openness, compatibility and cost efficiency.
Highly secured
Security from the transmission of wireless data packets to data access and management on the software hosted on the cloud or on-premise.
Low maintenance
High availability & redundancy, horizontal scalability through automatic load balancing and supervision tools with automatic alerts
Technical architectures
Ubudu Hybrid RTLS technical architecture can be used separately or simultaneously.
Infrastructure can even be mutualised between different technical architectures.
UWB Time Difference of Arrival (TDoA) uses the difference in the time of arrival of the signal received by different anchors from the tag to measure the distance of the tag to the anchors and compute a position through trilateration.
Best accuracy and stability
This architecture provides 20-30cm accuracy and accelerometer data is used to stabilise the positions.
Best latency
The positions of thousands of tags can be updated in real-time without any delay.
Best for
Industrial sites, warehouses, metallic environment with large open areas, high ceiling.
BLE Smart architecture uses the RSSi value of wireless BLE emitters (Beacons) received by the Tags and transmitted back to the network through Bluetooth Low Energy.
Good accuracy and stability
This architecture provides 2-3m accuracy and can be used also to locate tags by zone
Light and flexible infrastructure
Thanks to the use of wireless beacons, the infrastructure is light and the accuracy can be easily adapted to different areas.
Best for
Medium to big size venues with small open areas (hospitals, restaurants)
Retrofit existing building with simple wireless solution
BLE Smart LoRa architecture uses the RSSi value of wireless BLE emitters (Beacons) received by the Tags and transmitted back to the network through LoRa network.
Good accuracy
This architecture provides 2-3m accuracy and can be used also to locate tags by zone.
Very light and flexible infrastructure
No cabling needed for this architecture thanks to the use of wireless beacons and long-range LoRa gateways that can receive data from tags at a range of several hundred meters.
Best for
Very large sites with mix of indoor and outdoor (construction site, warehouse, factory).
BLE Network Directional architecture uses the RSSi value received by the directional antennas from the tags to detect the tag by zone in real-time.
Good accuracy
This architecture provides 2-3m accuracy and can be used also to locate tags by zone.
Good latency
Few seconds latency maximum to detect the tag in the zone which means that it can be used to detect entry / exits in zone to generate real-time alerts.
Best for
Small size venues with low ceiling and small open areas (restaurants, clinics) or when only entry/exit detection is needed.
New buildings with cabling still to be done.

UWB TDoA has the highest accuracy and can compute positions up to a 20-30 cm accuracy of thousands of tags simultaneously.
BLE frequency is 2.4GHz.
UWB supports 9 RF bands from 3.5 GHz to 9 GHz. We typically use channel 5 at 6.48 Mhz.
LoRa frequency for Europe is 868MHz.
Impulse radio UWB (Ultra Wide Band) outperforms other technologies because it is very short impulsions concentrate energy and are therefore more immune to multi-path and interferences that narrow band technologies such as BLE and Wifi.
Ubudu tags typically integrates an accelerometer or eventually even an IMU that can be used in conjunction with RF signals to estimate position of tags. In our mobile SDK we leverage all sensors from smartphones (GPS for outdoor, accelerometer, gyroscope, magnetometer, barometer). All sensors data and RF localisation techniques are fused with particle filtering algorithm methods (a set of Monte Carlo algorithms used to solve filtering problems arising in signal processing and Bayesian statistical inference).
