Instructions

Instructions on the cantenna exercise can be found here.

Final presentation

For the cantenna presentations, each group will hold a 5 minutes (!) presentation about its cantenna work.

During the presentation, each group is asked to briefly explain:

1. the theory behind the type of cantenna that has been chosen (not in details! just mentioning which type you have chosen and how it works),
2. the design of the cantenna (meaning which parameters you have dimensioned and their values),
3. the construction phase (shows the deployed can, the complete cantenna, and mention any particular construction work and/or fancy tools you used),
4. the testing set-up (which metrics have been used to test the cantenna and how you measured them),
5. and the testing results.

The cantenna presentations will take place during the last lecture of the security of wireless network course.

The presentations will take place in the usual lecture room. We will provide the necessary equipments (computer + beamer).

In order to reduce the time needed to switch between different presentations, the deadline to send us your presentations (reardonj@inf.ethz.ch) will be before the presentation (date to be announced).

For the cantenna presentation, please, bring your cantenna, the Orinoco card, and the pigtail cable. At the end of the lecture, we will collect the Orinoco cards and the pigtail cables. We will not collect the N-connectors. So, there is not need to remove them from your cantennas.

Workspace

We have some tools to help you building your cantenna in our lab room (IFW A-26), but no space to actually work on it.

As a workspace, there is a workshop at the HG (called "freizeitwerkstatt") that you can freely access to build your cantenna. Additionally, you should find there different tools as well.

For infos check this link.

If you want to access and use the freizeitwerkstatt, please, get in contact with the person in charge by yourself (contact details on the website).
