Cellular System MCQ [Free PDF] - Objective Question Answer for Cellular System Quiz

1. In the case of direct CDMA, interference will occur if the PN codes are

A. Orthogonal to each other
B. Non-orthogonal to each other
C. Orthogonal & Non-orthogonal to each other
D. None of the mentioned

Answer: B

If the PN codes are not purely orthogonal direct CDMA interference will occur.

2. If the active users using a cell doubles, the required Eb/I0

A. Doubles
B. Halves
C. Remains the same
D. None of the mentioned

Answer: B

If the active users were to double, then the received Eb/I0 would essentially be halved.

3. In CDMA ______ frequency reuse is possible.

A. No
B. 50%
C. 90%
D. 100%

Answer: D

In CDMA, 100% frequency reuse can be employed.

4. Bandwidth efficiency improvement involves

A. Dividing the geographical region into cells
B. Allowing frequency allocation
C. Dividing the geographical region into cells & Allowing frequency allocation
D. None of the mentioned

Answer: C

The idea of dividing the geographical region into cells and allowing frequency allocation of one cell can be reused represents bandwidth efficiency improvement methods.
