RTWP Troubleshooting Guide

Hello friend!

As far as I know, there is no RTWP Troubleshooting Guide, but you can check the product documentation for troubleshooting. 

To obtain the product documentation, click: Troubleshooting RTWP Faults

Hope this helps!

RTWP troubleshooting

1- check the cells configuration matches the physical hardware

2- check feeder path ( jumpers and cables and connectors) 

3- external interference

For more details, here is an article I wrote about RTWP Troubleshooting, you can read it.

Good answer, thanks

The NodeB measures the RTWP of each uplink channel in a cell every second. In the alarm reporting period (2 hours), if more than 80% of the measured value on the cell uplink channel is higher than or equal to the threshold (default value: –70 dBm), the Cell RTWP Excessive alarm is reported. After the alarm is reported, in the alarm clearing period (3 minutes), if more than 80% of the measured value on the cell uplink channel is lower than the threshold, the alarm is cleared. If the desensitization parameter is configured, the measured value on the uplink channel is modified based on the cell-level desensitization intensity. If the cell is enabled with GU@5 MHz, the threshold is modified based on the GU@5 MHz configurations.

First open maintenance client , monitor, Board RTWP
Choose the board
If R0A and R0B antenna channel the same value and up -70dBm that mean external interference.
If there different in the value about 6 dBm check DTF and VSWR or if 4T4R check E-tilt for antenna.
