OWIN6G Wireless Sensor Network

LED Tx panel — VLC downlink Access Point (corner ⅛-sphere) Sensor Node (truncated pyramid) IR uplink (SN → AP) Wired backbone / cloud

Radiation patterns

AP IR activation

Period 3.5 s
AP FOV 10°
Req. 10%
isoline = activation requirement; only SNs inside it activate.

EH — energy harvesting (floor)

LED FOV 45°
EH req. 35%
isoline = min. VLC power for energy harvesting at the SNs.

SN uplink (ceiling)

SN FOV 40°
Comm. req. 65%
isoline = min. power for SN → AP communication.

SN battery levels

Drag = orbit · Scroll = zoom · Right-drag = pan
