Case Project 5-4: Survey of Wireless Users Create a short survey to administer to wireless users regarding how they would typically use a free wireless network in a restaurant or coffee shop. Include questions such as, ‘‘Do you know the difference between an ad hoc and a secure wireless network?’’ ‘‘What precautions do you take when using a free wireless network?’’ ‘‘Can you list the dangers in using an open wireless network?’’ ‘‘Do you ever purchase anything that requires you to type in a credit card number while using a free wireless network?’’. Ask five friends or acquaintances for their responses. Based on these responses, give a grade of ‘‘A’’ through ‘‘F’’ to each wireless user. Now take the test yourself and give yourself a similar rating. What improvements can you make in using a free wireless network?
