View solution

Q. What happen to a call in fixed channel strategy, if all the channels in a cell are occupied?

View solution

Q. What is a borrowing strategy in fixed channel assignments?

View solution

Q. In dynamic channel assignment strategy, voice channels are allocated to different cells permanently.

View solution

Q. In dynamic channel assignment strategy, base station requests channel from ____________

View solution

Q. Dynamic channel assignment reduces the likelihood of blocking in comparison to fixed channel assignment.

View solution

Q. RSSI stands for ________

View solution

Q. What is the drawback of dynamic channel assignment?

View solution

Q. What is the condition for handoff?

View solution

Q. Handoff does not require voice and control channel to be allocated to channels associated with the new base station.

View solution

Q. The time over which a call can be maintained within a cell without handoff is called _________

View solution

Q. Dwell time does not depend on which of the following factor?

View solution

Q. Which of the following is associated with the handoff in first generation analog cellular systems?

View solution

Q. MAHO stands for ______

View solution

Q. A handoff is initiated when the power received from the base station of a neighbouring cell falls behind the power received from the current base station by certain level.
