Each cell of a wireless system, is partitioned in 6-sector as shown in Figure 8.13.





(a) What will be the impact of channel-borrowing and co-channel interference

if sectoring scheme of (i) is used?

(b) Repeat (a) if the scheme of (ii) is used?

(c) How do you compare (a) with (b)?

(d) Is it possible or desirable to use a combination of sectoring schemes of (i)

and (ii)? Explain carefully.


(a) Sector x can borrow channels from sector e because either the reuse distance

is satisfied or the directions of e sectors are such that they will not interfere

with sector x.







(b) Similar with (a). Co-channel interference is the same as the analysis done in

Chapter 5. There are only one co-channel interference sector for each sector.







(c) See parts (a) and (b).

(d) No. It makes the borrowing scheme more complicated. Because in a simple

sectoring scheme, you only need consider the effect on the co-channel

interference of a single cell and the scheme could be applied on all other

cells.
