UWB positioning technology has become a hot spot for wireless positioning technology in the future due to its low power consumption, good anti-multipath effect, high security, low system complexity, and especially its ability to provide very precise positioning accuracy.
UWB positioning technology advantages:
UWB positioning is an emerging wireless communication technology with high speed, low cost and low power consumption. The signal is a pulse signal with a bandwidth greater than 500MHz or a ratio of baseband bandwidth to carrier frequency greater than 0.2. It has a wide frequency range. The FCC specifies a frequency band from 3.1GHz to 10.6GHz, and limits the signal's transmit power to below -41dBm.
It can be seen that the application focuses on two areas, one is the short-distance high-speed data communication that conforms to the IEEE802.15.3a standard, that is, the wireless transmission of large amounts of multimedia data without delay, and the rate must reach 100Mbit/s-500Mbit/s; and the other One is low-speed and low-power transmission in accordance with IEEE802.15.4a for UWB positioning.
The characteristics of the signal show that it has the advantages of low cost, anti-multipath interference, and strong penetration ability in positioning, so it can be applied to the positioning and tracking of stationary or moving objects and people, and can provide very precise positioning accuracy.
UWB positioning application areas:
Industrial/Automotive: Track assets and inventory in real time, improve processes, improve search efficiency, and reduce waste of resources;
Logistics warehousing: tracking barcode readers and forklifts, reducing insurance inspection links, and making warehousing management flexible;
Military: UWB positioning and equipment tracking, such as warehouse management, advanced research and development;
Medical care: real-time tracking of patients, care and management, which is conducive to disease analysis and treatment improvement, and is convenient for human resource management;
Dangerous environment: locate individuals and resources, emergency search for safe locations, personnel monitoring, and optimize management processes to achieve safety and effectiveness;
Key security areas: personnel entry and exit management, real-time location query, jin zone supervision, isolation distance control, personnel scheduling, monitoring and statistics of personnel location, travel route, distance, and speed;
Sports: real-time tracking and calculation of the direction and speed of the athletes, detailed performance analysis, recording of the team's live competition, and video integration.
