Publication number: 20170163334Abstract: A method for modifying a communication signal for transmission from a source to a destination includes identifying, by data processing hardware, a target platform for communication with a communication device. The method includes establishing a communication connection between the target platform and the communication device and identifying an available communication channel for communicating data between the target platform and the communication device. The method also includes modifying a communication signal by multiplying the communication signal with a pseudo random noise spreading code. The method also includes causing transmission of the modified communication signal from the communication device to the target platform through the available communication channel.
