DEMONSTRATE THE IMPACT OF WIRELESS TECHNOLOGY
How many devices do you own or use that transmit signals (not just computer data) wirelessly? Think of as many as you can, and make a list showing the different types of signaling used by each device. Don't forget that some devices use multiple wireless technologies, like cell phones with both cellular signals for voice transmissions and Bluetooth for syncing their address books.
Hint: Don't forget cordless phones, TV and stereo remotes, radios, and portable computers and PDAs with infrared capability (look for a small, glossy black window somewhere on the edge of the case). Can any of your devices communicate with each other?
