UNIT 7:Radio Network Planning

A

1

Primary objective of frequency planning?

Maximize capacity

2

What is the minimum acceptable Signal-to-Interference ratio (S/I) for the AMPS analog system, which is equivalent to 63.1 in linear scale?

18 dB

3

What comes from cells far away that happen to be using the same frequencies as your serving cell?

Co-Channel Interference

4

 GSM parameter that prevents intra-cell collisions between users?

MAIO(Offset)

5

What happens to a new call in Fixed Channel Assignment when all pre-assigned channels in a cell are occupied?

Blocked

B

1

Gain provided by frequency hopping to combat independent signal fades?  

Frequency diversity

2

Constant number of first-tier co-channel interferers in hexagonal geometry?

6

3

What specific scenario occurs when a nearby high-power mobile overwhelms a receiver tuned to a weak desired signal?

Near-far scenario.

4

GSM control channel that is strictly prohibited from frequency hopping?  

BCCH carrier

5

What is the maximum number of individual GSM radio channels (ARFCNs) allowed in a single Mobile Allocation hopping set?

 64 ARFCNs
