InfiLINK XG

Parameter Description
value
Higher CINR is better
RSSI
Displays the Received Signal Strength Indicator
measured in downlink and expressed in dBm
Represents the power of the received signal as a whole
(useful signal plus noise and interferences) and if it goes
below the level of the sensitivity, the link will go down
Acc TBER
Displays the Transport Block Error Ratio, showing the
percentage of errored transport blocks
Each application has an acceptable air block error rate
defined as a minimum requirement
The values are presented in the table below
Table 23 - Wireless Links Statistics
CINR and RSSI are very important in analyzing the link performance. Below there
are the guidelines for CINR and RSSI levels:
CINR (dB) Comment
5…12
Very low quality signal suitable for low-order modulations
only. It is highly recommended to improve signal quality by
selecting less congested channel or increasing signal level
13…19
Low signal quality, average modulations are available
20…27
Average signal quality
>=28
Very good quality signal suitable for highest-order
modulations
Table 24- CINR value ranges
RSSI (dBm) Comment
-90…-80
Close to the receiver sensitivity level, suitable only for the
lowest modulation levels; it is highly recommended to
improve signal level or switch to narrower available channel
width in order to avoid the loss of connectivity
-80…-60
Average input range
-60…-40
The recommended range for achieving best performance
>-40
Input signal level is too high, it is recommended to decrease
the Tx power in order to avoid possible damage of the radio
module of the remote unit
