A.

Call Setup Success Rate

B.

Handover Success Rate

C.

Call Drop Rate

D.

Voice Quality

Question 4
Multiple choice

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.

location area code plan

B.

propagation model

C.

type of terrain in the area

D.

BAL measurements made by UEs

E.

Question 5
Single choice

How would you connect a Baseband module in the eNodeB to an Antenna Integrated Radio (AIR)?

A.

using optical fiber

B.

using a microwave link

C.

using an RJ-45 Ethernet cable

D.

using Bluetooth

Question 6
Single choice

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?

A.

Signal attenuation from the transmitter to the location has increased.

B.

The antenna pattern of cell A has changed.

C.

The PRB utilization of cell A has decreased.

D.

Soft handover factor has increased.

Question 7
Multiple choice

An operator receives customer complaints from an indoor location. The Issues result from a bad neighbor plan in a single RAT and frequency network.

Which two optimization processes would you use to resolve the problem? (Choose two.)

A.

call trace based neighbor optimization

B.

drive test based neighbor optimization

C.

PM counter based neighbor optimization

D.

prediction based neighbor optimization

Question 8
Multiple choice

Which two statements about physical resource blocks (PRB)s are correct? (Choose two.)

A.

The maximum number of assigned PRBs for a TTI can exceed the number of available PRBs in the cell for that TTI.

B.

The DL PRB distribution is not affected by the number of active cell users in the cell.

C.

A higher throughput is expected when more DL PRBs are assigned to a user for a TTI.

D.

The number of PRBs assigned for a user is dependent on the number of active users in the cell.

Question 9
Single choice

Which statement is correct about power control on an HS-PDSCH channel?

A.

Available power for the EUL channel impacts the HS-PDSCH data capacity.

B.

Inner closed loop power control is used.

C.

Available power and radio conditions impact the HS-PDSCH data rate.

D.

Outer loop power control is used.

Question 10
Single choice

Which statement describes uplink Discontinuous Transmission (DTX)?

A.

DTX is a method of saving battery power for the BTS by turning off the transmitter while "voice" is not present.

B.

DTX is a method of saving battery power for the MSC by turning off the transcoder while "voice" is not present.

C.

DTX is a method of saving battery power for the BSC by turning off the transcoder while "voice" is not present.

D.

DTX is a method of saving battery power for the MS by turning off the transmitter while "voice" is not present.
