Detailed Product Description

WiSens® LQI Plotter is designed to analyze the LQI (Link Quality Indication) values (ranging

from 0-255) of a ZigBee network. WiSens® LQI Plotter comes with a combination of USB hardware dongle along with a PC Application software on Windows platform. The USB dongle captures the OTA (Over the Air) ZigBee Packets from the vicinity and then plots the LQI Values of the ZigBee devices(at the vicinity) through the PC Application Software.

 

Available Features

 

Anyone of the 16 Channels (from 2405 2480 MHz) can be chosen & selected for Analyzing

 

Identifies the MAC Address/IEEE 16bit Address of every OTA ZigBee packet captured

 

For every uniquely identified ZigBee device there is an exclusive floating child window

(comprising a graph with X & Y coordinates plotted) displayed by the PC Application Software

 

The floating child window represents a graph, where X axis - 'No. of packets' denoting the

number of packets captured from each ZigBee device with respect to

Y axis LQI Values ranging from 0-255

 

The floating child window title displays the ZigBee device address (identified by MAC

Address/IEEE 16bit Address)

 

The verbose messages (at the PC Application) displays the raw data for all the OTA ZigBee

packets(along with their source address) captured by the USB Dongle

 

The Status bar displays 'the total no. of ZigBee devices in the network, the no. of ALL packet

counts from the ZigBee devices in the vicinity, the no. of error counts from all ZigBee devices
