Question 1:
Create a table that lists all 2G, 2.5G, and 3G mobile telephone standards. Carefully
research the latest sources to determine the following parameters for each standard:
(a). RF channel BW; (b). peak data rate; (c). typical data rate; (d). responsible
standards body; (e). maximum number of concurrent users; (f). modulation type.

Question 4:
Draw a cellular network with the hexagon cell shape and cluster size equal to 4. Mark the
frequency assignments in each cell.
Using: N = i2 + ij + j2
For N = 4
Choosing i = 0, j = 2
Steps to find the nearest co-channel neighbours of a particular cell:
19
1. move i cells along any chain of hexagons
2. turn 60o counter-clockwise and move j cells.
This is the location of our next co-channel cell.
