You have been asked to provide consultation to you friend, 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 at any time varies depending on the time of day and day of the week. On slow shifts, there are usually only 10 operators, whereas at peak hours, there are 50 operators. She has bids from different companies to install (1) Wi-Fi, or (2) a switched Ethernet 100 Base T network. She wants you to give her some sense of the relative performance of the alternatives so that it can be related to the costs of each option. What would you recommend?
