ABSTRACT:
An electromagnetic data transmission system is disclosed wherein a first and a second data link are connected between a transmitter CPU and a receiver CPU. The first data link, which is for transmitting data with high throughput rates, has a multi-directional electromagnetic transmitter at the transmitting end which can transmit electromagnetic signals in a plurality of different directions over three different dimensions and an electromagnetic receiver at the receiving end. The second data link, which is for providing status and feedback information, has a wide beam electromagnetic transmitter at the transmitting end and an electromagnetic receiver at the receiving end. The inventive method herein, then, includes the steps of transmitting a plurality of test signals in each of the directions of the multi-directional electromagnetic transmitter of the first data link, determining which of the test signals were received most clearly, and finally transmitting data in a number of optimal transmission directions.
