Hi Gordon,

I am not sure which of the questions you are referring to here.  If you
are still talking about question 2.3, you can determine the number of 
sectors from the angles provided.  For 120 degrees sectoring, the cell 
will be separated into 360 degrees divided by 120 degrees, which is 3 
sectors.  Similarly, the 60 degrees sectoring will sub-divide the cell 
into 6 sectors.

If you are referring to question 2.5, N=7 for both part a and b of the
question.  Remember that sectoring [done in part b] does not change the
number of cells in a cluster.  The only thing that changes is the number
of trunks per sector.  This is calculated as:

     Number of Channels / Number of Sectors
     = 57 / 6 = 9.5      [Number of Sectors = 360 degrees / 60 degrees]

Kassim.
