Homework 2


This problem should be done in a small group with a maximum of two people, though you can do it by yourself.  You want your write ups to be a couple pages for each problem.  Succinctness is important, and you're likely to want to number your responses to coincide with the questions.  But try to use complete sentences when reasonable.

  1. Draw a diagram of a relatively small wireless network focusing on a single AP

  3. How is security/access done?  Is there encryption?
  4. Have you seen the system get bogged down with too many users?  What is it like?
  5. Have you seen difficulties with losing the signal?  What sorts of things seem to be the source of these difficulties?
  6. Does the AP have an IP address? 
    1. Is it static?
  7. Do the client devices have IP addresses? 
    1. If they do, how are they assigned?
    2. If they don't how does the AP identify the client?
