LAN Media Selection Criteria
47. Why is copper cabling susceptible to eavesdropping?
When electric signals travel across copper wires, they create an electrical field that can be
detected outside of the wires. Using the right equipment, this field can be intercepted and
interpreted.
Criteria for Choosing Network Media
48. What are the benefits of installing a wireless network?
Wireless networks can be used to extend your network, whether you need a temporary
connection, you need to span a greater distance than your existing network can handle, or you
are not able to install wiring due to the type of building material. Wireless can be used as a
backup solution. Wireless also allows users to roam.
49. What are the benefits of fiber-optic cabling?
Fiber-optic is capable of much higher bandwidths. Fiber-optic cabling is immune to EMI and
RFI so it has no problem with interference. It also has no leakage so it is highly secure,
almost impervious to eavesdropping. Because of low attenuation, fiber-optic cable can travel
greater distances at a higher bandwidth.
