Digital Matter has been asked numerous times for a device that can be used to locate items indoors – where even the best GPS will not work – such as in a warehouse or basement. This version of the Yabby uses a Wi-Fi ‘sniffer’ to scan for Wi-Fi access points and the signal strength from each one. This information is then used to triangulate a position which is typically accurate to 30 m in metropolitan areas. This can typically all be done in less than 3 seconds, using a lot less power than a typical GPS fix.
This Wi-Fi sniffing combined with the new low-power capabilities of the LTE-CATM1 module allows the company to shrink the design size down even smaller and use smaller AAA batteries.
