Place Order

Uh-oh, the Legal department and the HR department are demanding their own network.
The departments feel that their data is sensitive enough that their data should be separated from the other departments.
In addition, the Outside Sales department has gotten brand new Apple iPads for all of their users. So there needs to be a Wireless network setup so they can go online.
So, you need to build out a change order for the network to account for these two curveball requests.
Your submission should be in a Word document and should cover the following (not a complete list)

How will you separate the networks, physically or virtually?
What type of WiFi network will you setup?

What hardware will you use?
What encryption method will you use?
Will you limit the WiFi signal via physical means?

What additional hardware is needed? Software? Etc?
Remember to justify your choices
