We use the Iiwari Dashboard to demonstrate how accurately the Iiwari positioning system works.
It is also possible to purchase the Iiwari Development Kit for your own testing so that the benefits of historical data collected by positioning can be visually verified.

The patent defines the MBS (Master Base Station) and BS (Base Station) devices that send positioning messages, which allow the receiver of the messages (tag / portable device) to determine the TDOA (Time Difference of Arrival) values between the MBS and BS devices and use them to calculate their own location. The method enables an unlimited number of devices to be located.
The patent obtained together with VTT defines a method for wirelessly locating electronic price tags using UWB and inductive technology.
Local radio technology (inductive radio) or radio technology or an optical method is used for positioning.
The benefits of the technology are that very low-current electronic labels can be positioned and their number on one shelf can be almost unlimited.
The patent application defines MBS and BS devices that act as base stations of the positioning network. The ultra-low current identification device (tag) sends Blink messages, which are received by the MBS and BS devices. In addition, MBS devices periodically send synchronization messages, which enables wireless synchronization between MBS and BS devices and between BS-BS devices. The patent application defines a method for calculating TDOA values between MBS-BS and BS-BS devices. The TDOA values are used to calculate the tag position.
The patent application defines MBS and BS devices that act as base stations of the positioning network. The MBS and BS devices periodically send synchronization messages, which enables wireless synchronization between the MBS and BS devices. The patent application defines a method for calculating TOF values (Time of Flight) between MBS-BS and BS-BS devices. TOF values are used to calculate the positions of MBS and BS devices.
