Start by doing what's necessary; then do what's possible; and suddenly you are doing the impossible. This has been the ethos of Swedish tech company Wittra who sought a solution for accurate positioning over narrow-band radio technologies, something previously considered impossible. Wittra today is announcing the introduction of their Time-of-Flight (ToF) based positioning functionality, complimenting their existing Received Signal Strength Indicator (RSSI) capabilities. Wittra continues to make the impossible possible.

Taking a different approach to positioning, Wittra’s technology is based on much lower radio frequency (sub-GHz, license-free SRD/ISM) bands. The advantage is improved signal transmission range, both outdoors, underground and indoors in a single technology deployment. For the first time, users can implement a reliable and accurate positioning system (±5 meters accuracy 85% of the time) at a low cost, as the required density of “anchor points” throughout the site is much lower than other short-range technologies such as WiFi, Bluetooth and Zigbee, which are limited in range and offer positioning with varying accuracies which can be up to several tens of meters.

Wittra has implemented a combined ToF and RSSI positioning algorithm called WiPE (Wittra intelligent Positioning Engine). WiPE is configurable and can operate in different modes, RSSI only, ToF only and a combined mode. The benefits of this approach to indoor and outdoor positioning are:

High accuracy with consistent results
Robust… can work in a large variety of radio environments
Economical… low density infrastructure (relatively low number of anchor points)
