This page contains all the information related with the project In-Flight file transfer for group Red:
In a scenario in which mobile wireless communications are restricted, like in the case of being in an airplane, sharing files between mobile devices may not be possible. In previous years, some alternative solutions that do not use RF signals have been explored, such as the usage of the phone speakers and microphone, as well as the camera and the screen (QR codes). The problem with such methods, is that the rate is heavily limited due to channel impairments like external sounds or visual limitations.
In this year’s project, we will use a different approach, which is: to transmit a file using an audio cable. To achieve this, we will use the audio/mic jacks as transceivers and then, connect two phones with a 3.5mm cable to send a modulated audio signal with the file information. The transmission and reception of such file will be managed by the Android application that is to be developed. In this way, we expect to achieve a higher throughput compared with the case of transmitting sound over the air [Continue to Project Plan...].
