The Advantages of Ultrasonic Indoor Positioning System

Ultrasonic indoor positioning is widely employed in various economic sectors, including businesses, hotels, warehouses, and healthcare.

FREMONT, CA: With the rapid global growth of the internet, information about people and assets is essential for businesses to optimize their business processes. Numerous techniques are used for indoor navigation, which relies on precisely calculating coordinates and transmitting them to a specialized platform for processing. One of these technologies is ultrasonic indoor positioning. Due to the system's capacity to accurately define the position of objects within a few millimeters, it has tremendous potential for integration with commercial and corporate infrastructure.

Ultrasound is a term that refers to a range of sound waves with frequencies that are too high for humans to hear—typically greater than 20 kilohertz (kHz). Using the ultrasonic range to determine position is a typical tactic found in nature. Bats are well-known for their reliance on echolocation to identify insects, generating ultrasonic pulses as high as 200 kHz and extraordinarily sensitive to minute variations (as low as .0001 kHz). Numerous cetaceans and some fish travel, hunt, and communicate via ultrasound. The technique is based on ultrasound, which defines the frequency range of sound waves that are too high to be perceived by humans. Due to the ultrasonic locating system's ascending/descending signal transmission mode, the number of receiving devices is not limited during installation. Ultrasonic location is a more effective solution than GPS since it does not require direct visual contact between transmitters and signal readers. Ultrasonic location is based on the ToF (Time-of-flight) principle, which quantifies the time required for a signal to travel from the sensor to the receiver. Unique tags that transmit ultrasonic impulses are used to determine distance. The receiver network analyzes these signals and communicates data to the central system, which uses multilateration to identify the location within three centimeters.

Ultrasonic indoor positioning system signal update frequency varies between a sub-second and three seconds. Because of the technology, it is possible to obtain highly exact information about the location of an object within a few centimeters. An ultrasonic indoor positioning system can be incorporated into any business process. A few sensors ensure complete coverage of the area. Long-lasting batteries power the devices. An ultrasonic indoor positioning system is primarily accomplished wirelessly. Due to the battery power, it is feasible to fine-tune the system's operational deployment. The ultrasonic indoor positioning system simplifies diagnosis and program updates.
