When we step into a large shopping mall, face the complicated floor layout, or shuttle between the vast library shelves, or stay in the exquisite museum exhibition hall, are we eager to have an accurate, intimate and intelligent "guide"? Indoor positioning navigation system, like a magic key, quietly opened the door to convenient space utilization.

In the medical field, large hospitals are like a maze, and patients and their families are often lost on the way to find consulting rooms, laboratories and operating rooms. The indoor positioning navigation system is as accurate as meters or even centimeters, just like a "medical assistant" who is familiar with every inch of the hospital layout. It can not only plan the shortest and most convenient route for patients from the hospital entrance to the registration office, waiting area, and then to the examination department, avoid the congested area during the rush hour, but also monitor the patient's position in the hospital in real time. For patients with mobility difficulties, it can be linked with the intelligent wheelchair, automatically guiding the wheelchair along a safe and spacious passage, ensuring that patients can arrive at the medical place comfortably and on time, greatly improving the medical experience and efficiency, and making the use of hospital space more efficient and orderly. The ultra-wideband (UWB) technology behind it can achieve centimeter-level accurate positioning in complex buildings by emitting nanosecond-level non-sinusoidal narrow pulses, and has strong anti-interference ability, high stability and safety.

Looking at the warehousing and logistics industry, there are many shelves in the huge warehouse, and the goods are piled up like mountains. The indoor positioning navigation system seems to have a "perspective eye", which can accurately track forklifts, handling robots and cargo pallets in the warehouse. It guides the forklift to shuttle between shelves in the best route, carries goods quickly and accurately, and avoids narrow passages, obstacles and other equipment or personnel at work. At the same time, through the real-time positioning of cargo pallets, the accurate inventory and efficient management of goods are realized, and every inch of warehouse space is brought into full play, which accelerates the circulation of goods and reduces operating costs. For example, in a large e-commerce warehouse, with the help of indoor positioning and navigation system, the handling efficiency of forklift trucks has increased by 40%, and the loss rate of goods has decreased by 30%, greatly optimizing the operation of the warehouse.

In the underground parking lot, the space is dark and the layout is similar, and the owner often falls into an embarrassing situation where he can't find a car. The indoor positioning navigation system accurately presents the parking position of the vehicle on the owner's mobile phone, and plans the most convenient route for the owner according to the real-time traffic flow inside the parking lot. It can also be linked with the intelligent lighting system in the parking lot. When the owner approaches, the lights will automatically light up along the way, which not only guides the direction, but also adds safety and convenience, so that the underground space is no longer "dark and hard to find". Its unique Bluetooth beacon technology, by deploying a large number of Bluetooth nodes in the parking lot, forms a dense positioning network, which can provide accurate positioning services for car owners even in the underground environment with poor signal.

Indoor positioning and navigation system, a magical technology hidden in high-rise buildings, commercial places, transportation hubs and other buildings, is reshaping our cognition and utilization of indoor space with its professional and wonderful power, becoming an indispensable "space decoder" in modern society, leading us to travel in every corner of the room silently and exploring more unknown wonderful things.
