Figure 3-1: Example of deployment
1
The deployment study produced the following information:
• total number of radio areas in the company = 7 (from Z1 to Z7)
• total number of mobiles in the company = 90
2
The following information was supplied by the customer:
User mobility: medium
Distribution of mobiles in company:
• 10 mobiles in radio areas Z1 and Z4, "low" traffic
• 20 mobiles in radio areas Z2 and Z5, "medium" traffic
• 60 mobiles in radio areas Z3, Z6 and Z7, very "high" traffic
3
The final picture will be:
• Homogenous area 1 = Z1 + Z4, "low" traffic area
N/Z = 10/2 = 5, i.e.1 base station per radio area
• Homogenous area 2 = Z2 + Z5, "medium" traffic area
N/Z = 20/2 = 10, i.e.2 base stations per radio area
• Homogenous area 3 = Z3 + Z6 + Z7, very "high" traffic area
N/Z = 60/3 = 20, i.e.3 base stations per radio area
Homogenous area 1 has one cell (cell 0), homogenous area 2 one cell (cell 1), homogenous
area 3 three cells (cells 2, 3 and 4), i.e. one cell per radio area to handle the traffic.
