Introduction The Ubitag V1.0 is a wireless device intended to be used for the real-time location of objects within buildings. It transmits ultra-wideband (UWB) pulses which are picked up by a network of basestations (Ubisensors) placed inside the building, allowing the 3D position of the tag to be found. The use of UWB technology enables greater positioning accuracy within buildings than other wireless technologies, because it is much less susceptible to multipath interference effects.
PAGE 4
Features of the Ubitag The diagram below shows several important features of the Ubitag: Ubisense – Ultra-wideband In-Building Location System – Ubitag V1.
PAGE 5
Installation and Operation Instructions Switching the Ubitag on for the first time The Ubitag is supplied with batteries. A paper tab prevents the device from operating and drawing current from the batteries until it is removed by the user. The Ubitag can be switched on for the first time by pulling the paper tab directly away from the body of the Ubitag and clear of the device, as shown in the photograph below.
PAGE 6
Replacing the batteries in the Ubitag The Ubitag uses two Sony CR2450 3V lithium coin cells (or equivalent). Ubitags frequently report their battery health to the system via the Ubisensors, so system administrators should be notified by the system when the batteries in a particular tag require replacement.
PAGE 7
Leave the Ubitag unpowered for 30 seconds, then insert two fresh batteries into the retainers, observing the polarity marked on the battery and the retainers: When both batteries have been replaced, the Ubitag will bleep once and flash its LEDs to indicate correct start-up, and the Ubisense In-Building Location System will then be able to determine the Ubitag’s location. Replace the back of the Ubitag and tighten the four screws removed previously to complete reassembly of the device.
PAGE 8
Troubleshooting The activity of the LEDs on the Ubitag may be used to diagnose potential problems with the device: • • Periodic, short (less than 1/10th second) flashes of the green LED indicate that the tag is in communication with the local Ubisensor network, and that the device is emitting ultrawideband signals enabling its position to be found.
