Out of over 200 companies developing and delivering technology for indoor location positioning, the 28 companies profiled in this report deliver indoor positioning to an accuracy of less than one meter. While this is not important for some applications, for many applications it is critical.
For solutions determining which store in a shopping mall a user is in, or which booth in a conference a user is near, positioning within several meters may be sufficient. But for solutions tracking whether a customer is standing in front of the pretzels or the chips in a supermarket, or which patient in a hospital ward a nurse is checking, or other similar applications, accuracy within less than a meter is necessary.
In the past year we have seen particular growth in four specific areas. The first is dedicated hardware systems that track the locations of smartphones using innovative methods. The second is lighting-based systems, in which customized LED lights transmit signals that are received by smartphone cameras. The third is visual camera-based systems, which use computer vision technology to determine location or track motion. The fourth is the incorporation of high-accuracy location positioning chips into electronic appliances, such as wearables, Internet of Things, Smart Home, and more. In addition, a small number of companies have achieved sub-meter accuracy by adding innovation to common software-based methods.
The 28 companies whose technologies are analyzed below are on the cusp of high accuracy indoor location technologies. These companies present the opportunity right now to deliver highly accurate location positioning indoors.
