Coshamport is a large city. In order to transform Coshamport into a smart city, capable of providing a high quality of smart life to its residents, the municipal government plans to build a broadband wireless metropolitan area network (MAN) that will cover the entire city area (17,500 square meters)—this will provide the convenience and benefit of wireless Internet access to all in the region.

Cost Centres:

Cost centres are the resources that are used directly to produce the end product.

Cost centres include human resources such as design engineers, project managers as well as equipment such as controllers. Human resource is a major cost center, the resources needed are assigned as well as the driver rates determined. Also, the activities are identified e.g. planning, designing and implementation as well as the drivers for such activities as well.

 

One Major Direct Cost Centre:

Major cost centre includes the cost of hiring Human resources to replace the wires between the controller and the sensor manager and active sensor unit with a WLAN.

 

Indirect Cost associated with Human Resource:

Indirect expenses are the overhead costs that need to be allocated to the project. These expenses include room rent, cleaning, computer purchasing and maintenance, water, software, network administration, paper, printers and the like.

(3)  Referring to the top-down network design approach, prepare a meeting agenda for discussing network requirements with budget holders. [16 Marks]

(4)  Prepare a full tradeoff table and discuss one technical goal with the highest number and another with lowest number. [18 Marks]

(5)  Discuss typical problematic network design practices using some illustrative examples. [16 Marks]

(6)  What are main metrics with which the performance of this wireless MAN can be measured? [16 Marks]
