On the bottom-right side of the "Status" page the «Clear All Counters» button is present with the scope of resetting the counter values to 0 when clicked on.
| Warning |

|
Clearing these counters by clicking on the «Clear All Counters» button means losing the history data about the functionality of your unit. Avoid this operation unless you are completely sure you don’t need this data in the future. |
The "Status" page has the following sections:
- "Interface Statistics" - displays the main parameters of all configured interfaces (physical and logical).
- "Wireless Link Statistics" - displays the main parameters of the radio link.

| Wireless Link Status | - Displays the status of the radio link which can be

“Up” or “Down” | | Measured Distance | - Displays the measured distance of the radio link in meters
|
If the remote end stats is disabled, the measured distance is only shown at the slave unit| Channel Width | - Displays the channel bandwidth that is in use

| | Parameter | Description |
|---|
| Tx capacity | - Displays the maximum transmission capacity expressed in Kbps for the current modulation and coding scheme
|
; if - . If the MCS changes, the Tx capacity will also change accordingly
| | Tx/Rx Frequency | - Displays the center Tx frequency expressed in MHz
| | DFS status | - DFS status information. Possible statuses:
- "NO_INIT" - utility is not initialized
- "DISABLED" - DFS is disabled
- "ENABLED" - DFS is enabled
- "FG_RADAR_SEARCH" - selected frequency scanning for radars existence
- "FG_RSSI_SCAN" - all available frequency grid noise level scanning
- "RADAR_FOUND" - radar found
- "RADAR_UP" - frequency with radar is blocked for selection
- "BG_RSSI_V" - "background" RSSI on the vertical channel
- "BG_RSSI_H" - "background" RSSI on the horizontal channel
- "BG_RDRDT_MAIN" - radar "background" searching on the main frequency
- "BG_RDRDT_ANNOUNCE" - radar "background" searching on the potential frequency
- "BG_FF_UL" - uplink frequency changing
- "BG_FF_DL" - downlink frequency changing
| | Tx/Rx Frames | - Displays the number of transmitted and received air frames
| | Rx Bad frames | - Displays the number of air frames received with errors for which the Control Block cannot be correctly decoded
| | Rx Acc FER | - Displays the Frame Error Ratio, meaning the percentage of frame loss (air frames that cannot be decoded divided by the total number of air frames received)
| | Tx parameters |
|---|
| MCS | - Displays the modulation and coding scheme that is in use at Tx side. There are
|
10 - 11 MCS schemes available and if the AMC is set to auto, the MCS will dynamically change its value based on the link quality (at both units - local and remote). The maximum Tx capacity varies based on the MCS in use.
- For example, for
|
QAM256 “QAM256” - “QAM256” is the modulation in use, “7/8” is the coding scheme in use (for every 7 data bits encoder produces 8 bits to be sent over the air) and “(8)” represents the index of the MCS in use
| | Power | - Displays the current power level of the Tx signal for each radio chain in dBm
| | Rx parameters |
|---|
| MCS | - Displays the modulation and coding scheme that is in use at Rx side. The representation is similar to that for Tx part
| | CINR | - Displays Carrier to Interference and Noise Ratio measured in downlink and expressed in dB
- CINR can be limited either due to too low signal level or because of the interference from other radios
- AMC algorithm makes its decisions based on the CINR 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

For the InfiLINK XG 1000 family models the real time radio link parameters are displayed for both radio modules. |
CINR and RSSI parameters
CINR and RSSI are very important in analyzing the link performance. Below there are the guidelines

| Table - | value rangesRSSI | 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 | | | -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
