Summary of Location device work indoors with 10cm accuracy
DecaWave unveiled its first ScenSor wireless device, a range-finding IC enabling indoor location tracking with 10cm accuracy. Operating on the IEEE802.15.4a standard, it serves as a high-precision alternative to RFID and WiFi where GPS is unavailable, supporting data rates up to 27Mbit/s over 50 meters.
Parts used in the ScenSor project:
- Range-finding IC
- Wireless signals transmitter
- Readers for object location
Dublin-based wireless location chip firm DecaWave has introduced its first ScenSor wireless device at an event hosted by Irish Prime Minister Enda Kenny.
The range-finding IC works by transmitting wireless signals to readers that use them to locate the tagged object to within 10cm.
The device is based on the IEEE802.15.4a standard, which is an extension of the 802.15.4 ZigBee low power wireless comms standard. It supports data rates up to 27Mbit/s in a range up to 50 metres and locating accuracy of about +/- 10 cm.
It is being proposed as an alternative to RFID and WiFi technology currently used for indoor tracking, where satellite-based GPS signals are unavailable.
“Until now, 10cm location communications across close distances was not possible and current systems with metre-level accuracy have limited reliability,” said Ciaran Connell, CEO at DecaWave.
