Overview

This tag is designed to be used with Ekahau's Wi-Fi RTLS (real-time location system). Per the datasheet, features include...

  • naturally, real-time location reporting to their controller server (ERC) and privileged users (via Ekahau Vision or something else [via XML API])
  • OLED text display for text messaging
  • audio buzzers and two LEDs for alerts
  • a duress / panic switch (pull out the unit's top hook, shown used with a lanyard)
  • a motion detector for an auto man down alert

Per the FCC docs..

Additional specifications, per Ekahau's datasheet, follow...

  • Battery: 600mAh Li-Poly battery, rated for 300 cycles w/ > 70% of initial capacity, 2 hr charge time
    • The badges use a high-energy, rechargable battery that works for weeks (depending on location update interval) without recharging). The battery can be charged using individual desk chargers or a rack charger which can charge up to 10 tags at a time.
  • Tx Putput Power: +12dBm
  • Recieve Sensitivity: -93dBm @ 1Mbps (?? PER / BER)
  • Typical Operating Range
    • Open space: 330ft / 100m @ 11Mbps, 500ft / 150m @ 2Mbps
    • Closed office: 140ft / 40m @ 11Mbps, 200ft / 60m @ 2Mbps
  • Weight: 46 g / 1.7 oz
  • Dimensions: 60 mm x 90 mm x 8.5 mm

The 00:18:8E OUI is per the FCC EUT's label. It may not be representative of in-use devices.
