Abstract
We set out to develop a device that plugs into your phone and works with an app to without communication without cell phone service or WiFi. This would be useful if you are going on vacation to a cruise or service-less area outdoors and want to communicate with family or fellow travelers across long distances.
We implemented the hardware portion of this project by using a researched Xbee chip set that has the ability to broadcast signal approximately a mile away. This chip set was rigged to interface with the audio jack of a phone.
We implemented the software phase by programming a phone app, which is responsible for modulating and demodulating the signal and translating text into an audio signal for the audio jack output.
