ECP-383 Ericsson Certified Associate - Radio Network Optimization Questions and Answers
Which KPI must be captured in a drive test with TEMS to review VoLTE accessibility?
You are performing a physical parameter optimization of an LTE network with an automatic tool that uses propagation predictions. As a result, the tool estimates an increase of RSRP from cell A at a particular location.
In this scenario, what has happened?
Using a cell optimization tool, you detect a sector that takes a large amount of traffic from a distant location that is covered by other sites and is also outside of the coverage predicted for this sector.
Which physical optimization action should you perform first In this situation?
A customer has Identified problems In an Indoor, medium loaded, urban area of a GSM/WCDMA collocated network. The problem seems to be in the uplink. The signal level received by the problematic site is high, and the downlink signal in the problematic area is acceptable.
Which two actions would you use to troubleshoot the issue? (Choose two.)
After an optimization meeting, an operator decides to double the transmitted power of an LTE cell. To test the effect of this change, a static test is performed before and after the change.
Which statement is correct in this scenario?
Which two interfaces are part of a standalone 5G New Radio (NR) architecture? (Choose two.)
Which two statements are correct about voice quality in a VoLTE network? (Choose two.)
After the installation of a new LTE antenna on a roof top, UL interference power for that sector is observed.
In this scenario, which two situations would cause the interference? (Choose two.)
Which two benefits does OSS counter-based optimization provide compared to drive test measurements? (Choose two.)
You have collocated sectors In your 2G network on the GSM 900 and the DCS 1800 bands. Reviewing the network level traffic distribution, you noticed that the GSM 900 sectors have five times more traffic than the DCS 1800 sectors.
Which two actions would improve load balancing between these bands? (Choose two.)
