Indoor Real-time Location System



Indoor RTLS Targets the ePOS and retail, automotive, agriculture, building control and automation, factory automation, healthcare, safety and security, warehousing and logistics and a range of other Applications.

Utilizing the 802.15.4-2011 Ultra Wide Band (UWB) technology, this allows for accurate Time of Flight (TOF) and Time Difference of Arrival calculations to provide a precision indoor/outdoor ranging solution for tracking objects down to 10cm Accuracy* without GPS. Low Power TDoA algorithms provide the end user with location information using simple web API's or a MQTT feed. 

A Real-Time location system is used to provide tacking and management of equipment and personal with high accuracy. 

Pure Engineering has developed several products to support your high accuracy indoor location tracking needs.  

UWB Anchor and Gateway
A UWB Anchor provides functions to support indoor location tracking and transport of the location data to the server. UWB and BLE  sensing are both supported to provide different tracking methods.  
  • UWB anchor: provides fixed location data to the tags that request it. 
  • UWB Wifi Bridge: Provides a data path for the Tag to send the location data to servers
  • BLE Scanner: Can scan standard existing BLE devices that are not using UWB technology. Enables lower cost tags, but with less accurate location information. 
  • Internal Mesh: Can be used to extend the range of UWB/BLE scanning coverage without additional WiFi AP infrastructure. 
  • Compatible with third-party UWB and BLE tags (depending on implementation) No lock-in.
  • Self locating: enables quick setup and reconfiguration. 
  • $29 each for 1500 MOQ.
UWB Tag
  • Ultra low power Tag, 1 year+ battery life
  • UWB radio for high high accuracy indoor location tracking and transport of location data to base-station devices. 
  • BLE capable for configuration and backup location information, and sending of location data
  • BLE smartphone interface: allows adding location awareness to your smartphone application. 
  • MEM's motion sensor for smart power management, and triggering events on start and stop of motion. 
  • $29 each for 1500 MOQ.
UWB Basestation
A UWB Base-station provides mutiple functions to support indoor location tracking. UWB, BLE and proximity sensing are all supported to provide mutiple tracking methods.  
  • UWB anchor: provides fixed location data to the tags that request it. 
  • UWB Wifi Bridge: Provides a data path for the Tag to send the location data to servers
  • BLE Scanner: Can scan standard existing BLE devices that are not using UWB technology
  • USB bridge: Can connect to a USB host providing direct hardwired connection to the Base-station, in addition to providing a low cost power source. 
  • Narrow FOV Proximity Sensor:  Sensing of people and direction of movement in front of the Basestation, up to 4M range. Used for tracking movement of personal without UWB tags. Primary function is to be placed across a entry way to count number of people entering and leaving a room. Person counting does not require UWB or BLE tags. Also can be used as an intrusion detection system for unbadged persons.   
  • Compatible with third-party UWB tags (depending on implementation) No lock-in.
  • SigFox Ready: allows for transport of UWB data over sigfox or custom UNB for non WiFi connected Basestations.  
  • Under $39 each in volume
Location Server
  • Provides a central point for all location data to be archived. 
  • Database provides high resolution data for 24 hours(programmable) for real time assist tracking
  • Data is compressed down to manageable data-points for archive and data analysis. Key data points that are archived are timestamped entering/exiting of programmed locations. 
  • BLE beacon data estimated locations based on RSSI can be requested. System uses UWB location data to build accurate indoor BLE RSSI location methods over time.  
  • API's to trigger on location aware events. 
  • Device Management: deploy new firmware to devices, track device health and battery life. 
  • Included with volume purchase of Gateway devices. 

Standard deployment consists of placing one UWB base-station per room to maintain coverage so that a tag can maintain 30M range to at least 4 base-station units. The Base-station units can be paired to an existing WiFi network. Not all base-stations are needed to connect to Wifi, but at least one unit needs to be connected to transport the data to the server per groups of 20. The Anchor devices will all self location relative to each other. By configuring 3 fixed locations the entire UWB network will switch to WGS84 coordinate system. 

Customization is available for your particular application.
