Question

What is a borrowing strategy in fixed channel assignments?

(a) Borrowing channels from neighbouring cell

(b) Borrowing channels from neighbouring cluster

(c) Borrowing channels from same cell

(d) Borrowing channels from other base station in same cell

I had been asked this question during an internship interview.

This interesting question is from Channel Assignment Strategies topic in chapter The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Correct choice is (a) Borrowing channels from neighbouring cell

The explanation is: In borrowing strategy, a cell is allowed to borrow channels from a neighbouring cell if all of its own channels are already occupied. The MSC supervises such borrowing procedure and ensures that the borrowing of channel does not interfere with any call in progress.
