New description: - [New technical field] -· This creative department provides an indoor wireless positioning system, especially a wireless sensing network that can be built in an uncertain terrain environment. The signal strength level 'to estimate the position of the device to be positioned. [Prior Art] In recent years, positioning technology has been widely used in daily life, and the development of outdoor positioning and technology is a major breakthrough. Among them, GPS satellite positioning system is the most common, but because the indoor environment is not easy to receive signals, GPS satellite positioning is not available indoors, so many positioning technologies have gradually developed many different types of indoor positioning systems. The development of wireless networks is a major breakthrough. Many of the advantages are not met by wired networks. For example, the convenience of construction, the complexity of the lines, the terrain space, etc. are all difficulties for cable networks. . Since many people often have the problem of forgetting where their belongings are placed, I think that if you can use it - wireless communication I set up with the fixed tilting technique, you can directly solve the position of the item we are looking for by computer, I believe that many people can solve it. Troubled. So 'how to develop an indoor wireless positioning system that can build a wireless sensing network in an uncertain terrain %, and use the received signal strength illusion to estimate the position of the device to be clamped, will be This creative office wants to actively explore.
