In this scenario, which two situations would cause the interference? (Choose two.)

A.

Equipment that generates electrical magnetic fields are in the same location.

B.

The antenna was placed on a mast near the edge of a rooftop.

C.

A plastic enclosure was placed to cover the antenna.

D.

Reflective objects such as metal chains or metal ladders were placed in front of the antenna.

Question # 12

A.

less than 33 dBm

B.

36 dBm or more Independently of the maximum transmission power

C.

8-10% of min[maximumTransmissionPower, maxDlPowerCapability]

Question # 14

Which two statements are valid for Call Re-establishment in WCDMA? (Choose two.)

A.

Call Re-establishment in WCDMA targets RL failures or RLC errors in the DL.

B.

When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE selects a new cell using the soft handover procedure.

C.

Call Re-establishment in WCDMA improves the voice drop rate.

D.

When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE goes to idle mode.

Question # 15

Which two statements are true about the Antenna Integrated Radio (AIR)? (Choose two.)

A.

The AIR is a hardware unit that integrates the radio and the antenna.

B.

The AIR replaces the digital/baseband unit.

C.

The AIR in an LTE system is directly connected with the MME using the SI interface.

D.

The AIR can replace the standard RU/RRU and antenna.

Question # 16

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.
