1. Pat’s Petunias : You have been called in as a network consultant by your cousin Pat, who operates a successful mail-order flower business. She is moving to a new office and wants to install a network for her telephone operators, who take phone calls and enter orders into the system. The number of operators working varies depending on the time of day and day of the week. On slow shifts, there are usually only 10 operators, whereas at peak times, there are 50. She has bids from different companies to install (1) Wi-Fi or (2) a switched Ethernet 100Base-T network. She wants you to give her some sense of the relative performance of the alternatives so she can compare that with their different costs. What would you recommend? Use the format below to begin working on the report. Given : Assumptions: Comparison: WiFi – IEEE 802.11 100Base-T Switched Ethernet Performance: Discuss reason for collisions How would you solve collisions? How can you give a good throughput?

Pros and Cons Summary Pros and cons summary Suggestion based on the analysis in the above table: Solution I think she should consider Wi-Fi because the data rates for Wi-Fi have increased substantially with the introduction of 802.11n, so they are similar to the data rates offered by 100Base-T wired Ethernet. Wi-Fi is considerably cheaper than wired Ethernet because the largest cost of LANs is not the equipment, but in paying someone to install the cables. The cost to install a cable in an existing building is typically between $150 and $400 per cable, depending on whether the cable will have to be run through drywall, brick, ceilings, and so on. The cheapest point at which to install network cable is during the construction of the building; adding cable to an existing building can cost significantly more. Additionally, it’s more convenient for anyone walking or driving within the range of the AP (access point) can begin using the network. IV.

Case 2: Eureka! Company
Eureka has just leased a new office and are considering options for wiring it. Most users at the
company bring their own laptops to do work. They have bids from different companies to install
(a) a shared Ethernet 100Base-T network, (b) a switched Ethernet 100Base-T network, or (c) an
802.11ACwireless network.
What would you recommend and why?
South West State University installed a series of four Wi-Fi omnidirectional APs spread across
the ceiling of the main floor of their library. The main floor has several large, open areas plus
two dozen small offices spread around the outside walls. The WLAN worked well for one
semester, but now more students have laptops, smart phones, etc. and performance has
deteriorated significantly.
