It331: Technology Infrastructure Essay Example

You have been asked to design a LAN with operation over a distance of about 100m. Compare and contrast twisted pair cable, coaxial cable, fiber-optics, and wireless for this application. You should create a table or flow chart which would facilitate choosing between these options depending on circumstances. The table or flow chart should be submitted as part of your document. You may not submit a separate file. Twisted Pair Cable
Media Type Coaxial Cable Wireless Fiber Optics UTP STP
Maximum Segment Length (Thicknet)

(Thinnet)
185 m 802.11a=60ft
802.11b=92m
802.llg=300ft

100 Mbps
Cost Relatively inexpensive, but more costly than
UTP Can be much more cost effective than buying and installing cables Expensive Least expensive Not expensive but more expensive than UTP
Advantages Less susceptible to EMI interference than other types of copper media Slower, more interference, and can be unstable Cannot be tapped, so security is better; can be used over great distances; is not susceptible to
EMI; has a higher data rate than coaxial and twisted-pair cable Easy to install; widely available and widely used Reduced crosstalk; more resistant to EMI than Thinnet or
UTP
Disadvantages (Thicknet)
Difficult to work
With, limited bandwidth (Thinnet); entire network can crash if cable is damaged It is difficult to terminate Susceptible to interference; can cover only a limited distance Difficult to work with; can cover only a limited distance 2. An entrepreneur is interested in establishing her own world-wide satellite radio infrastructure and has requested your help. Describe and justify the infrastructure that you would develop.
