"this system will not allow 2X information to be carried" I believe that is the entire point of the article. To allow double the capacity between two devices.

"this system will not allow 2X information to be carried" I believe that is the entire point of the article. To allow double the capacity between two devices. The original capacity would be the amount of data that could be sent by a single device. However if both devices can send at the same time that is double capacity.
