Wi-Fi is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices.
Wi-Fi uses multiple parts of the IEEE 802 protocol family and is designed to interwork seamlessly with its wired sibling Ethernet. Compatible devices can network through wireless access points to each other as well as to wired devices and the Internet. The different versions of Wi-Fi are specified by various IEEE 802.11 protocol standards, with the different radio technologies determining radio bands, and the maximum ranges, and speeds that may be achieved.
This is the previous blog about AR remote instruction.
In AR remote instruction, the supporter or the client will have a problem, that is very often unable to find the target location and cannot provide assistance. Almost all locations are indoor environments, such as warehouses or offices.
Therefore, we searched some existing research information to investigate which methods are suitable for find out the target location.
Indoor positioning system (IPS) includes many kinds of methods. And we talk about the Indoor positioning system (IPS) in the previous blog. It explains in detail how to use iBeacon as IPS auxiliary positioning.
The other method name is the Wi-Fi positioning system.続きを読む
