Zigpos product line up
Dresden-based Zigpos came to Embedded Technology 2016 to showcase its “seamless indoor/outdoor navigation” technology – energy efficient real-time location system dubbed “eeRTLS.”
Zigpos uses Ultra-wideband (UWB) chips designed by DecaWave (Dublin, Ireland).
Leveraging the IEEE 80215.4 standard that uses the globally available 2.4GHz IMS band, UWB-based Zigpos’ eeRTLS solution can be integrated into beacons and objects. Multiple distances are measured from beacons with known locations which can be used to triangulate an object's position.
In the era of IoT, expect ZigBee and Bluetooth LE connectivity to proliferate everywhere. These wireless technologies are already used for location applications, but their protocols are designed for data streaming. By bringing UWB into the mix, “We can directly measure distances -- with an accuracy of 30cm,” Zigpos’ managing director Christoph Goetze told EE Times.
The value of eeRTLS technology is that location information is no longer limited to outdoors. The eeRTLS can be used both in indoor, outdoor or mixed scenarios in a completely independent mode of operation, the company explained.
Zigpos anticipates wide-ranging applications in smart factories, offices and homes. This includes real-time object and person tracking for home automation, industrial sensor/actuator networks, logistics, retail chain support, smart transportation and IoT.

The ultimate advantage, however, is in achieving lower power consumption.
The company said that the system saves more energy by using time-synchronized networks and cognitive mechanisms to automatically set algorithm parameters based on the user environment. Every single device can be accessed via defined interfaces to the Internet of Things.
