Resources

If you're reading this, you've obviously already found the ECE445 web site. It is extremely important that you familiarize yourself with the website as soon as possible, since all major semester milestones are organized using PACE. Documents are uploaded to your Project Page for grading, meetings are scheduled, and parts are requested. In addition, we use PACE as our general discussion board for the semester and Compass2g to manage grades.

Below is a list of important links you'll use all semester:

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.

Description:

We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
