Product Overview

The Viconics wireless survey tools are intended to verify

and validate the deployment and use of the Viconics

wireless controllers on a potential job site.

 • 2x120Vacchargerforthetools

Before performing a survey, please insure that

both survey tools are fully charged overnight.

The survey tool will display a numerical percentage

value on the LCD screen which represents the wireless

network ZigBee RSSI dBi value (Receiving Signal Strength

Indicator).

Please note that it is normal for the value to

uctuate slightly (up to 10-20%). The nal

ZigBee Mesh Network Overview

ZigBee is a specication for a suite of high level

communication protocols using small, low-power digital

radios based on the IEEE 802.15.4-2003 standard for

wireless personal area networks (WPANs).

Mesh networking is a type of network where each node

in acts as an independent router. It allows for continuous

connections and reconguration around broken or

blockedpathsby“hopping”and“re-meshing”fromnode

to node until the nal destination is reached.

General characteristics of the wireless physical

communication layer are:
