Question # 13

Using a radio performance monitoring tool, you fetch counters CI and C2 and calculate KPI K for the four 15-minute ROPs in an hour. The values obtained for the CI and C2 counters and for KPI K are shown In the exhibit.

In this scenario, what is the hourly value of KPI K?

Options:

A.

The value obtained for KPI K is 97%.


B.

The value obtained for KPI K is 96%.


C.

The value obtained for KPI K is 95%.


D.

The value obtained for KPI K is 94%.

Question # 16

An operator's LTE single layer network has a cell not carrying enough traffic. To increase the traffic carried by the cell, the operator decides to modify the Idle mode behavior of the cell. Values for the qRxLevMin and qQuaimin parameters are currently set to -120 dBm and -12 dB.

Referring to the exhibit, which two configurations would be used to potentially increase the traffic carried by this cell? (Choose two.)

Options:

A.

Set the qRxLevMin parameter to -117 dBm.


B.

Set the qQualMin parameter to -15 dB.


C.

Set the qQuaiMin parameter to -9 dB.


D.

Set the qRxLevMin parameter to -123 dBm.


Expert Solution
Questions # 17:

Why is synchronized operation used in LTE TDD base stations?

Options:

A.

to allow downlink MIMO to be used


B.

to allow handovers to LTE FDD carriers


C.

to achieve good RACH timing accuracy


D.

to reduce interference between uplink and downlink


Expert Solution
Questions # 18:

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.)

Options:

A.

adding additional GSM 900 sectors


B.

changing the handover margin


C.

expanding the site's transmission link


D.

changing the idle mode cell reselection parameter
