Ubisense UWB RTLS sensors<br />
Angle-and-time-sensing receivers<br />
• Planar array of four UWB receivers per sensor<br />
• Angular resolution ~ 1<br />
• Time resolution ~ 200ps (≡6cm distance)<br />
Sensors connect via Ethernet network<br />
• Use existing structured cabling<br />
• Powered over Ethernet<br />
• Optional networking via WiFi<br />
Cellular architecture<br />
• Similar to mobile phone systems<br />
• Scale to large sites by adding more cells<br />

RTLS installation procedure<br />
Step 1: Site survey to<br />
assess characteristics<br />
of the facility<br />
Step 3:<br />
<strong>In</strong>stall<br />
cabling for<br />
sensor<br />
network and<br />
connection<br />
to computer<br />
network<br />
Step 2: Design<br />
the layout of the<br />
sensors to give<br />
the optimum<br />
performance<br />
Step 4:<br />
Calibrate<br />
the system<br />
using<br />
survey<br />
equipment<br />
Step 5: Operate<br />
the system to<br />
provide location,<br />
tracking, recording<br />
