UWB navigation

Ultra-wideband positioning (UWB-positioning) is one of the latest technologies for determining indoor positioning. Navigation accuracy is up to 0.5 meters. Ultra-Wideband (UWB) is a wireless communication protocol that uses electromagnetic radiation at high frequencies with a wide bandwidth. This allows you to transfer large amounts of data, consuming little energy.

Deploying a navigation solution based on Ultra-Wideband positioning is now expensive, but provides high accuracy in tracking movements in the building.

Basically, UWB tracking is used to track tangible assets, access to hazardous areas in the enterprise and control the execution of work processes in the field. Contributes to increased security.

In sports, UWB navigation allows you to track players on the field, control the location of exhibits in museums and exhibitions, and find goods on shelves faster in warehouses.

Using Ultra Wideband for indoor geolocation.
Navigation: With the help of UWB technology, it is possible to determine the location of a person in a building with high accuracy and display it on the map of his smartphone screen, with the ability to guide along the route to the desired point. Mobile devices supporting UWB technology provide an accuracy of determining the position in the room up to 0.5 meters.
Tracking movements: UWB technology helps to carry out training of personnel and tangible assets in the premises with high accuracy. Control of hazardous areas, goods in the warehouse, placement of employees and equipment in production, social distance, movements of the security service, has a positive effect on the overall safety of the facility.
Analytics: The use of solutions based on the UWB protocol allows you to collect high-precision statistics of user behavior at your enterprise and analyze it using heat maps visualizing the distribution throughout the territory. The analysis of places with critical situations is especially relevant for their further prevention and damage reduction.
UWB positioning technology UWB is a radio communication protocol that uses a wide bandwidth with short pulses with very little power consumption. Ultra-Wideband uses a high repetition rate of short pulses to improve positioning accuracy and data transfer rates that can reach 100 Mbit/s, which makes UWB an excellent solution for transmitting information over short distances. The graph clearly shows the frequency range of UWB in comparison with other positioning technologies. Due to the narrow frequency band, most of the traditional solutions for indoor navigation are affected by various third-party interference and obstacles in the form of a large crowd of people in the room, the presence of partitions and columns, reducing data transmission speed and accuracy.

Positioning methods using UWB technology can provide accurate tracking of the indoor position in real time and can be used in such areas as: navigation for blind and visually impaired people, tool tracking in production, search for victims and the source of danger by emergency services, and more. UWB positioning methods provide the most accurate assessment of the location in the premises (from 0.1 to 0.5 meters). Thus, UWB positioning can be considered one of the most suitable options for mission-critical tracking solutions that require high-precision results.

How does UWB positioning work

The deployment of a solution based on Ultra WideBand technology can be carried out by trained specialists in a very short time. First of all, a specialist creates a map of the room in which navigation needs to be organized in the INP platform editor.

USB receivers are installed in the room and connected with a UTP cable to a POE switch with Internet access or a local server on which special software for indoor navigation is installed. The distance between Ultra-Wide Band receivers should not exceed 50 meters. For example, in a room of 2500 m2 (50x50 meters), 4 UWB receivers will be required, which must be installed in its corners. In the control panel of the Indoor Navigation Platform, equipment location points are added to the room layout.

Users are given specialized UWB tags or a mobile application is installed on their device with UWB support. Ultra-Wide-Band tags have different form factors (badge, wristband, helmet tag, etc.) and functionality (feedback button or call for help, determining the user's fall, collecting temperature information, etc.). pressure). Depending on the solution of the necessary tasks, the most suitable beacons are selected.
