Wireless Network Quality Indicators

Step	Action
1	Launch the PowerTag Link webpage in the web browser.
2	Login with user name and password.
3	Click Diagnostics > Communication > Wireless Network Quality Indicators.

The Wireless Network Quality Indicators page displays wireless network quality information such as Link Quality Indicator (LQI), Received Signal Strength Indicator (RSSI), and Packet Error Rate (PER).

Parameter	Description
Modbus Address	Displays the Modbus address of the wireless device.
Asset Name	Displays the user-defined asset name of the wireless device.
Usage	Displays the user-defined usage of the wireless device.
Product	Displays the type of wireless sensor.
LQI	Displays the measurement of the strength and / or quality of the received frames. The following values of LQI indicates the quality of the received frames: The value from 0...29 indicates that the RF communication is bad. In this case, check whether the rules of installation are followed. You can also change the location of the PowerTag Link gateway inside the panel to be near to the wireless device. The values from 29...59 indicates that the RF communication is average. In this case, look at the RSSI value whether to accept the level of quality or not. If the RSSI is above limit, consider the value of LQI as acceptable. The value greater than 59 indicates that the RF communication is OK. NOTE: It is recommended to use this indicator as the main indicator of acceptance.
Radio Quality	Displays the quality of the frames. When the LQI value is greater then 59, it indicates with green light and when LQI value is lesser than 29, it indicates with red light. When the LQI value is between 30 and 59, it indicates with orange light.
RSSI	Displays the power level of the wireless signal between the PowerTag Link gateway and the wireless device. Good: 0...-65 dbm Average: -65...-75 dbm Bad (with risk of outage): < -75 dbm
PER	Displays the ratio of the packet that does not reach a destination over the total expected number of packets and is expressed in percentage. For PowerTag Link gateway, the ratio is calculated over a fixed window of five minutes.

Email Service
