Question 3:4
By experimentation, work out the lowest SNR, under which 4 users can si- multaneously communicate, without error, via this system. For SNR, simply report the largest value for the noise power parameter, in the spreadsheet cell which changes the strength of the noise. Your answer should include a report on experiments in which the messages could be repeatedly communicated successfully, and also reports of experi- ments in which communication sometimes failed.
Question 3:10
It has become established practice to define network security by means of rules. These rules can take many different forms. Although security is often con- cerned with preventing access, good security requires consideration of other aspects than merely preventing access. Rules may state what types of service or activity are not allowed, and also what should be allowed. Rules may take precedence over other rules.
Complete set of rules for the following situations:
(i) A network of wireless access which is provided in a nationwide network of ho- tels;
(ii) a university campus network (with three types of user – academics, admin, and students);
(iii) a home wireless network.
In each case, include both positive and negative rules, and also rules which are not sim- ply about access, and attempt to ensure that the resulting set of rules is unambiguous, complete, and consistent.
