The new method by which signals are sent from Earth is designed to effectively deliver commands and instructions using hundreds of millions of tiny transmitters, all linked together in what is called a phased array. Such a method could also free giant satellite dishes currently used to send and receive the long-range information for other applications.

The technique is based on a method of aligning a number of mini-transmitters alongside one another and directing their combined beam into the sky. Such a system has previously been used for military technology, but has only recently become cost effective for civilian use.
