Drive test for 2G to 5G Flashcards
Choose 2G GSM drive test parameters
1) Rx level
2) Rx Quality
3) C/I: The carrier-over-interference ratio
4) FER: Frame Erasure Rate
All of them
In 2G drive test, FER stands for
1) Frame Error Rate
2) Frame Erasure Rate
Frame Erasure Rate
shows dropped frames
2G GSM drive test parameter FER is indication of
1) voice quality
2) data quality
voice quality
FER: Frame Erasure Rate
2G GSM drive test parameter Rx quality is measured on the basis of
1) FER
2) BER
BER: Bit Error Ratio
Range 0-7 where value 0 denotes minimum BER
Choose 3G GSM drive test parameters
1) CPICH Ec/No
2) CPICH RSCP
3) RSSI
4) SIR
all of them
1. Chip Energy by Noise- Common Pilot channel Ec/No
2. Received signal Code Power
3. Received Signal Strength Indicator
4. Signal to Interference ratio
In 3G drive testing, _____ shows the level of Noise disrupting the specific CPICH
1) CPICH Ec/No
2) CPICH RSCP
CPICH Ec/No
0 to -7 Good
to -10 Acceptable
10 to -36 Bad
In 3G drive testing, Ranges for Ec/No: (-36 to 0)
0 to -7 Good
to -10 Acceptable
10 to -36 Bad
In 3G drive testing, Tx Power is the power of a mobile station measured in the dedicated mode. It ranges from ______dBm to ________dBm
50 to -50
In 3G drive testing, choose the correct one
1) RSSI= RSCP + Ec/No
2) RSCP= RSSI + Ec/No
1) RSSI= RSCP + Ec/No
Choose 3G GSM drive test parameters
1) SQI
2) RRC STATE
3) TX POWER
4) AS
all of them
SQI: Speech Quality Index
AS: active set
3G GSM drive test parameter AS indicates
Active Set
Set of scrambling codes on which the user equipment is currently latched on.
There can be at least maximum three scrambling codes in an Active Set.
In 3G drive testing, there can be at least maximum ______ scrambling codes in an Active Set.
1) one
2) two
3) three
4) four
three
Neighbor cell that is detected by user equipment as a neighbor
1) MN: Monitored Neighbour
2) DN: Detected Neighbour
3) Active set
MN: Monitored Neighbour
The cells detected by UE, which are neither in the Active set nor in the Monitored set
1) MN: Monitored Neighbour
2) DN: Detected Neighbour
3) Active set
DN: Detected Neighbour
In 3G drive testing, set of scrambling codes on which the user equipment is currently latched on
1) MN: Monitored Neighbour
2) DN: Detected Neighbour
3) Active set
Active set
In 3G drive testing, ______ are used to identify different cells of a node B
