EXAMPLE OF A LOCAL AREA NETWORK (LAN)
Diagram of your Instructor's Local Area Network.
My ISP supplied Cable Modem (not shown on the diagram) would
be located at the word "Internet" on this diagram and
connects directly to airport3b (Router).
Each AirPort Extreme is a Wi-Fi Access Point and can also
be configured as a Router.
Each solid line represents a cat5/6 ethernet cable. Ethernet
cables connect Modem to airport3b (Router), which in turn
connect to airport1b (Wi-Fi Access Point) and airport2b
(Wi-Fi Access Point).
The three Wi-Fi Access Points located at opposite ends of
the house provide good coverage in any room. Mesh routers
achieve similar coverage without cables.
