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 />
