Ericsson Certified Associate - Radio Network Optimization Sample Questions:
1. Review the exhibit.
A new residential area has recently been built showing a lack of 3G uplink coverage as shown in the exhibit.
The terrain is flat and all the buildings in the area are 20 meters in height with no other relevant direct obstacles.
What should be applied to cells A_l and 8_1 to provide 3G service to the new area knowing that both cells have a soft handover (SHO) factor of 1.9?
A) Reduce the antenna height.
B) Increase the CPICH power.
C) Increase the electrical downtilt.
D) Change the azimuth.
2. Which two benefits does OSS counter-based optimization provide compared to drive test measurements?
(Choose two.)
A) OSS counters provide OPEX cost savings.
B) OSS counters only capture the outdoor performance.
C) OSS counters capture the indoor performance.
D) OSS counters allow throughput measurements in cells where no traffic is carried.
3. 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) Install TMA and verify the result.
B) Increase the antenna height and verify the result.
C) Increase the transmit power and verify the result.
D) Downtilt the antenna and verify the result.
4. Which two statements about the Radio Connection Supervision (RCS) algorithm in LTE are correct? (Choose two.)
A) It controls the modulation and coding scheme used in DL transmissions.
B) It selects the number of PRBs assigned to users for downlink and uplink.
C) It collects radio problems and inactivity information with the purpose to release resources.
D) It supervises the radio connection between E-UTRAN and a UE in connected mode.
5. You are making a frequency plan for a new site and you need to create an interference matrix for new GSM sectors.
In this scenario, which three inputs should you use? (Choose three.)
A) type of terrain in the area
B) location area code plan
C) propagation model
D) antenna height
E) BAL measurements made by UEs
