+In this thesis, I research an alternative short-range wireless communication method that uses magnetic induction instead of conventional radio waves for transmission of data and create a prototype that uses magnetic induction for communication.
-magnetic induction instead of conventional radio waves for transmission of data, and point out the advantages and disadvantages of magnetic induction as a communication channel.
-
-For demonstrating the communication method, I create a prototype implementation of a simple communication protocol that utilizes magnetic induction and that can be run using components found in everyday devices such as a smartphone and a laptop.
-
-At the end, I benchmark the prototype implementation under multiple conditions and configurations to illustrate how feasible and robust the communication is and if it is viable as an alternative to radio wave communication.

-The solution that I created for my thesis consists of two parts: a laptop that acts as the sender and a smartphone that acts as the receiver. The communication between the devices works over magnetic induction using a simple protocol.
+The goals of the prototype were that it should work one way between a laptop and a smartphone and that the transmission should also be possible, when no other connectivity is available e.g. when the phone is in airplane mode, as this is one of the advantages of magnetic induction based connectivity.
-
-On the sending side, by putting controlled stress on the processor of the laptop, an attempt can be made to manipulate the magnetic field that gets generated around the CPU. By manipulating the magnetic field in a controlled way, a payload signal can be encoded into the field. The sender was implemented as a website which allows the user to input a text, which then gets transmitted.
-
-On the receiving side, a smartphone is used to receive the signals from the magnetic field. By putting the smartphone on top of the sender, the magnetic field emitted by the CPU can be measured using a magnetometer, which is a sensor that is available in most modern smartphones. The received signal is then decoded and the contents of the payload can be displayed. This part was realized as a native Android application, which allows the user to listen for data signals in the magnetic field and display them on the screen.

-The results of my thesis is a pair of applications and a protocol that I call together \textbf{MagSend}.
+The solution that I created consists of two parts: a website for sending data and a smartphone application for receiving data. I call the complete system \textbf{MagSend}.
 
-MagSend allows the user to send small messages of up to 16 characters over a small distance using magnetic induction. The speed of the transmission is very slow with about 1 bit/s, and it is very susceptible to wrong results when other applications already use the CPU on the laptop or by moving the receiver during the transmission.
+On the sending side, by putting controlled stress on the processor of the laptop, an attempt can be made to manipulate the magnetic field that gets generated around the CPU. By manipulating the magnetic field in a controlled way, a payload signal can be encoded into the field. 
 
-In the future, MagSend could be improved by incorporating more sophisticated error detection methods and by increasing the transmission data rate.
+On the receiving side, a smartphone is used to receive the signals from the magnetic field. By putting the smartphone on top of the sender, the magnetic field emitted by the CPU can be measured using a magnetometer in the phone. The received signal is then decoded and the contents of the payload can be displayed.
