The main problem that this project is attempting to solve is finding a way to transmit electrical signals wirelessly through metal barriers. Due to metals electric conductivity it is impossible to get a wireless electrical signal to transmit through metal barriers.
To solve this problem any electrical signal that tries to pass this barrier will be received by a transducer and converted into an acoustic signal. Once this occurs the acoustic signal, with the correct frequency, will theoretically be able to transmit through the metal barrier and picked up by another transducer which will transmit that acoustic sound back into an electrical signal.
The main problems of this project are finding the correct frequency to transmit at. Very little work has been done on this topic before, but theoretically an audio signal should be able to transmit through the metal at either a very low dBm (infrasonic) or a very high dBm (ultrasonic). To find the right frequency two approaches will be taken. The first is to find use matlab ad simulink to create a theoretical box and test for the proper signal electronically. The second approach is to create two trial boxes, one made out of aluminum and the other steel, and then test using a signal generator and receiver to try and find the correct frequency by adjusting the signal constantly over time.
It is hoped that a similar signal will be found via both tests and therefore we will be able to move on to our next stages of the project.
